Peristaltic pump is a new type of industrial pump. In more and more industries, more and more peristaltic pumps are used in liquid transmission. Here chuangrui will share with you what is the pulsation in the peristaltic pump? Why reduce the pulse? What is a pulse? Because the peristaltic pump transmits fluid by alternately squeezing and releasing the flexible hose through the rotor, the flow transmitted will flow out in a stream, and the phenomenon of this transmitted liquid is pulsation. How do you reduce pulsation? 1, replace the soft tube In the case of satisfying the flow transmission, you can choose a thinner hose, and the pulsation will be smaller. 2. Increase the number of rollers Since the pulsation is caused by the rotors pressing against the hose, increasing the number of rotors is sufficient and the pulsation is already low with, say, 10 rotors running the pump head. However, it should be noted that as the rotor becomes more, the flow will become lower. 3. Y-type hose conveying Part of the pump head can be fitted with two hoses, which can be squeezed by cross during operation. The pulsation generated by the two tubes can be complementary to reduce pulsation effectively. 4. External pulse damper

With the different development in social production, the peristaltic pump is widely used in various industries, including water treatment, food and beverage, chemical research, medical and pharmaceutical fields, and plays a very important auxiliary role in the chemical reaction process. First, the liquid medicine used in the chemical reaction has a certain degree of danger, and second, there are high operational requirements in terms of accuracy. At present, the problems of high-risk factors and labor intensity are a kind of standard in chemical reaction work. The peristaltic pump is used for the supply of chemical reactions. By adjusting the mode of the peristaltic pump, the purpose of supplying the raw material pot to the pump of the reaction department can be realized, and the labor force can be replaced mechanically, which can directly reduce the labor intensity of the chemical experimenter and ensure the safe production of. (William Shakespeare, Stuart) To ensure correct machine values, and to improve experimental efficiency and output. Because of the corrosive nature of the chemical material, the 3354 hose, the only component in contact with the material, presents a significant performance challenge. So what are the conditions that need to be met when using a hose in a chemical reaction? 1. Jatan recovery -- the hose is pressed down by the drum of the pump head and quickly returns to the state before extrusion. In the chemical reaction supply process, the hose under the work of the peristaltic pump is subjected to a long time and high intensity of pressure and is directly in contact with the chemical raw materials. The poor magnetic elastic recovery of the hose will directly affect the delivery accuracy of the peristaltic pump and then affect the reaction results. 2. Wear-resistant and pressure-resistant 3354 hose have a long life due to long-term extrusion and friction. A peristaltic pump works by squeezing the pump tube and applying pressure to form flow. If the quality of the hose itself decreases in wear resistance, it is easy to cause damage and lead to raw material leakage. First, idling occurs, affecting production efficiency, followed by frequent replacement of new museums, resulting in economic waste. 3, corrosion resistance In the experimental production process, the hose is often in direct contact with chemical fluids, so it should have much higher chemical compatibility and corrosion resistance than ordinary pipes. The hose of good quality is an indispensable peristaltic pump part in the safety experiment and production process.

Paper chromatography is a kind of chromatographic analysis with filter paper as the carrier, its principle is mainly using the mixture of each component; They are separated by differences in the distribution ratio (solubility) between the mobile phase and the stationary phase. The adsorbed water on the filter paper is the stationary phase (the filter paper fiber can absorb about 20% water), the organic solvent such as ethanol is the mobile phase, and the pigment extract is the chromatographic sample. The sample point on the filtrate fine line position of the filter paper, when the mobile phase solvent in the filter paper under the action of the capillary, continuously along with the filter paper forward through the filtrate fine line, the components of the sample will move forward with the mobile phase solvent, and in the mobile phase and fixed phase solvent continuous distribution. Results The material with a larger distribution ratio moved faster and farther. The material with small distribution moves slowly and moves closer, and the components of the sample gather in different positions on the filter paper, to achieve separation. Keywords: paper chromatography, chlorophyll, separation, speed To master the method of extracting and separating pigment from the chloroplast. There are several pigments in chloroplasts. Carotene, lutein, chlorophyll A and chlorophyll B could be separated into four pigment bands with different diffusion rates of chromatographic solution on filter paper. Materials and Methods: Appliance: A pair of scissors, dry qualitative filter paper, 3 50ml beakers, and 3 100ml beakers, 3 pieces of white paper, 1 test-tube holder, 1 mortar, 1 glass funnel, nylon cloth or gauze, 1 capillary, 1 medicine spoon, 1 10ml measuring cylinder, 1 balance, 3 test tubes, 1 cardboard, 3 cotton plugs, 3 Petri dishes, scale, 1 syringe, cover glass Reagents: acetone, anhydrous ethanol, layer absorbent (20 parts petroleum ether, 2 parts acetone, 1 part benzene configuration), silica, calcium carbonate, sodium carbonate materials: fresh spinach leaves, green vegetable leaves (II) Methods and steps: 1. Extract pigment from green leaves (1) Take several green leaves, remove petioles and main veins, weigh 5g leaves with a balance, cut them into pieces, and put them into a mortar. (2) Put a little silica and calcium carbonate into a mortar and grind it thoroughly. Use a measuring cylinder to measure 5 ml acetone into a mortar and grind quickly and thoroughly. (3) Quickly pour the abrasive solution into a small glass funnel for filtering. Collect the filtrate into a small test tube and close the tube with a cotton plug. 2. Preparation of filter paper take a piece of pre-dried qualitative filter paper, cut the filter paper 10 cm long and 1cm wide, and draw a thin horizontal line 1cm away from one end of the filter paper with a pencil. 3. Draw the fine line of filtrate, draw a small amount of filtrate with a capillary pipette, and draw a thin and straight line of filtrate evenly along the pencil line. After filtrate, draw 2~3 times. 4. Separate the pigments from the chloroplast and pour 3 mL chromatographic solution into the beaker. Gently insert the filter paper (with the thin line of filtrate facing down) against the inner wall of the beaker, and then cover the beaker with a petri dish. (Note that the thin lines of the filtrate on the filter paper should not touch the chromatography. An organic substance used in paper chromatography Solvents such as acetone, are generally volatile and have certain toxicity, pay attention to sealing chromatography when using, and avoid inhaling too much harmful volatiles.) Results: After 10-15 minutes, the distribution of pigment bands after separation was observed. The top orange is carotene, followed by The yellow is lutein, the lower part is chlorophyll-a, and the lower part is chlorophyll-B. Discussion and analysis: Analysis: Paper chromatography is based on the principle of polarity similarity compatibility, which uses the combined water of filter paper fiber as the stationary phase and the organic solvent as the mobile phase. Due to the different distribution coefficients of each material in the sample, the diffusion rate is different, to achieve the purpose of separation. Generally used for the separation of pigments in chloroplasts, pigments in chloroplasts mainly include carotene, lutein, Chlorophyll A and chlorophyll B have different solubility in the chromatographic solution. The solubility of chlorophyll A and chlorophyll B diffuses quickly with the chromatographic solution on the filter paper, while that of chlorophyll B diffuses slowly with the chromatographic solution on the filter paper. The pigment band is wider when the content is higher. Four pigment bands were left on the filter paper, so the pigment in chloroplast could be separated clearly by paper chromatography. Discussion: 1. Chlorophyll and other pigment molecules are fat-soluble organic molecules. According to the principle of similar phase dissolution, chlorophyll and other pigment molecules are soluble in organic solvents but not in polar water. Therefore, when grinding and collecting chlorophyllin, organic solvents such as acetone or ethanol should be used instead of water. 2. Chlorophyll is distributed on the lamellar film of the grana, and a little silica is added to ground the cell wall, plasma membrane, chloroplast envelope, and photosynthetic tablet so that the pigment is dissolved in acetone. 3. The broken cells contain organic acids such as oxalic acid, and the Mg element contained in chlorophyll molecules is in an unstable combination state. The combination of magnesium ions and organic acids will lead to the destruction of pigment molecules. Adding a little calcium carbonate makes calcium ions bind to organic acids, reduces the transfer of magnesium ions, and prevents the destruction of chloroplast pigments during grinding. So the same goes for adding calcium carbonate as well as sodium carbonate when grinding. 4, choose absorbent cotton or gauze when filtering, rather than filter paper. The main reasons are as follows :(1) the pigment molecules are relatively large and it is not easy to pass through the filter paper; (2) The filter paper has strong absorbability so that the pigment is adsorbed on the filter paper, thus reducing the concentration of pigment and affecting the experimental effect; (3) chlorophyll is fat-soluble. According to the principle of similarity and compatibility, absorbent cotton can reduce the loss of pigment in the experimental process and enhance the experimental effect. 5. According to the capillary phenomenon in physics, the filter paper must be dried before drawing the filter paper fine line, to prevent water molecules from blocking the capillary in the filter paper and affecting the diffusion of the chromatography liquid. But if it is roasted with fire, it will deform the filter paper fiber and destroy the capillary, and affect the diffusion of the chromatography liquid. 6. Because the surface tension is different at different positions of the liquid surface, when the paper is close to the liquid surface, the surface tension at the edge of the paper is larger, and the chromatography liquid spreads too fast along the edge of the filter paper, resulting in the irregular separation of the pigment band. Therefore, two corners are cut off at one end of the filter paper and inserted into the chromatography liquid.

With the rapid development of peristaltic pumps, more and more industries with liquid transmission needs have been used, but in the use process, because of the unfamiliar with the pump, or other reasons caused by the use of problems, how to solve? Here to share with you. 1. No response after startup If there is no response after the peristaltic pump is powered on, check it in the following order. If there is still no response after checking, you can send a private message. If circuit protection is installed, make sure the circuit does not trip Make sure the power plug is inserted into a working socket Check whether the power cable is firmly inserted Check whether the fuse of the power interface is blown 2. The pump is started but cannot run First, you can check whether the coupling is damaged, if not, please cut off the power supply, manually turn the pump head, and dial the roller, whether the rotation is normal. 3, the pump transmission flow is low or no flow For example, if the flow rate is set to 0.1ml, the roller hardly moves. Set the flow rate to a higher one during the test. Secondly, you can also follow the following steps to check. Check whether the material supply is normal Check whether pipes are twisted or blocked Check that all valves are open Check that the hose is located in the middle of the rotor Check whether the hose is cracked or damaged Viewing the Running Direction Check whether the pump head rotor can rotate flexibly 4. External control cannot be controlled Regardless of the digital display type or LCD type, you can see whether the external control icon has been successfully switched on the screen. If yes, you can check whether the external control cable is correctly connected and whether the signal source Settings are normal.

Although the peristaltic pump has not been active in the market for a long time, its development time is very fast. Many industries with liquid transmission needs will want to know the advantages and disadvantages of the peristaltic pump and whether it is suitable for their industry. Next, Chuangrui will share it with you. 1, no pollution Because of the unique operating characteristics of the peristaltic pump, only the pump tube contacts the raw liquid, so it ensures the safety and pollution-free transmission process. 2, simple operation Compared to some other pumps, peristaltic pumps are simple to operate, just install the pump head and pump pipe, and then they are ready to run. 3. Scope of application Because the pump pipe material is diverse, so the application of the industry is also very wide, the transmission of liquid or corrosion, or more viscous and so on, can match the suitable hose. 4. High stability For industries that need the stable transmission of raw liquid, the peristaltic pump is the first choice, such as cosmetics, pharmaceutical liquid, etc., all choose the peristaltic pump. 5, high precision Peristaltic pump has a certain degree of transmission accuracy, which is very suitable for batch filling industries, such as nucleic acid reagent industry is the use of filling peristaltic pump, of course, if you have high requirements for accuracy, the injection pump is still recommended here. 6, dry operation Peristaltic pumps can be dry operation, avoiding accidents in production. 7, easy to clean The raw fluid only touches the hose, so when cleaning, only need to clean or replace the pump line, it is also very simple to operate. The following is the disadvantage of a peristaltic pump. After all, no matter how good the product is, it must also have shortcomings, which can not meet the needs of all people. 1. Pulse In the process of transmission of peristaltic pump, because it is through the roller to alternating squeezing and releasing the hose and running, so the liquid is a surge of outflow, even after the double roller pulsation decreases, it is hard to avoid completely, so if you can't stand the transmission fluid will have a little bit of ripple, the peristaltic pump is not suitable. 2, hose wear In the operation of the peristaltic pump, the hose is continuously squeezed by the roller, so the wear of the hose is inevitable, and the hose needs to be replaced regularly. Of course, compared with the maintenance of other pumps, the maintenance of the peristaltic pump is relatively simple.

When leaving the factory, the peristaltic pump has been debugged, but when customers use it, there are often differences. Why is this? There are a lot of factors affecting accuracy, here and we introduce one of the - suction and head impact on transmission. 1. What is suction and head First of all, we introduce the difference between the two. Suction refers to the height between the outlet liquid level of the delivery fluid and the pump head of the peristaltic pump, and the head is the vertical height between the pump head of the peristaltic pump and the liquid outlet. 2. What will be affected Under normal circumstances, the suction range is not more than 9 meters, the head is not more than 15 meters, and the impact on the accuracy is relatively small, but once the corresponding value is exceeded, it will have a significant impact on the accuracy of transmission, liquid backflow, flow rate drop and other situations. Of course, in addition to the accuracy will also have an impact on the stability of transmission, so under the condition of conditions, do not let the peristaltic pump head and suction reach the limit, otherwise, it will affect the production. 3. What else affects the accuracy In addition to suction and head, hose wear will also affect the accuracy of the peristaltic pump, so it is necessary to replace the peristaltic pump hose regularly, which can not only maintain the accuracy of the peristaltic pump but also avoid other accidents of the peristaltic pump.

Dispensing machine is also known as gluing machine or gluing machine. It is a kind of equipment specialized in fluid control. It has a three-axis platform and a four-axis platform for point, line, arc, and other ways of dispensing. So what is the relationship between the peristaltic pump and dispensing machine? We can through the characteristics of a peristaltic pump, and dispensing machine for more stable control. Stable transmission: because of the operation mode of the peristaltic pump, the liquid transmission of the peristaltic pump is more stable, and dispensing is more accurate. Simple maintenance: dispensing machine and peristaltic pump collocation for operation, machine maintenance is relatively simple, only need to regularly replace the transmission of raw liquid hose, low loss. Good sealing: in the process of transmission, the raw liquid only contacts the hose, to ensure that the raw liquid will not be contaminated, used in various production environments.

Today I will take you to understand the application of a peristaltic pump in tangential flow filtration: With the gradual formation of the new scientific revolution led by life science and biotechnology, the wave of biotechnology centered on medical biotechnology is developing in-depth. At the same time, the development of biomedical technology promotes the rise of a new industry - the biomedical industry. The biomedical industry involves modern medical fields such as disease prevention, disease diagnosis, biotechnology drugs, biological therapy, and regenerative medicine, and has become the high-tech industry with the best market prospect in the current biological industry. Separation and purification technology is the core of the biopharmaceutical process. To produce high purity and high activity biological drugs, the traditional separation, and purification technology can not solve the technological needs of modern biopharmaceutical enterprises. Due to the diversity of biological drug structures and the increasingly strict requirements of the regulatory authorities on the purity of biological drugs, the biological pharmaceutical process is very strict and stringent requirements on materials, making the separation and purification of biological drugs more and more difficult. Therefore, how concentrating, separating, and purifying target biomolecules from complex components economically and efficiently is often the bottleneck of biological drug production. Tangential flow filtration is an important process step in the biopharmaceutical process. In recent years, with the increasing concentration requirements of some injection products (monoclonal antibodies, vaccines, recombinant proteins, blood products, etc.), the production cost and operation difficulty are also increasing gradually. Tangential flow filtration is necessary for large-scale material and liquid filtration, which is beneficial to reducing the overall cost and making the realization of high concentration technology possible. Tangential flow filtration is one of the pressure filtration/membrane filtration technologies. In the traditional dead-end filtration technology, the flow direction of the filtrate is perpendicular to the filtration membrane and consistent with the filtration direction. Most of the small molecules pass through the filtration membrane, while the large molecules gather on the surface of the membrane. With the increase of time, the particles accumulated on the membrane surface also increase the filtration resistance increases, and the membrane permeability rate decrease. In tangential flow filtration, the flow direction of the filtrate is parallel to the filtration membrane and vertical to the filtration direction. A small part of small molecules pass through the filtration membrane, and large molecules are taken away from the membrane surface. With the increase of time, the number of particles accumulated on the membrane surface is limited, which does not affect the speed and effect of filtration. Tangential flow filtration is commonly used in the production of biological products, blood products, and vaccines. Advantages of peristaltic pump in tangential flow filtration application: 1. Peristaltic pump has low shear force, which can ensure the integrity and activity of biomolecules when pumping biological active substances. 2. Peristaltic pump is simple and convenient to replace the hose. In the laboratory, when transmitting different solutions, the cross pollution between different solutions can be avoided by simply replacing the hose that meets the hygiene level. 3. The flow can be manually adjusted or automatically adjusted by receiving the control signal from the external controller to ensure that the system pressure is within the allowable range. 4. Accurate and controllable flow can maintain the continuous filtration of a tangential flow filtration system to achieve the desired concentration effect. 5, The use of a Pharmed tube, good corrosion resistance, good wear resistance, and the hose service life is more than 10 000 hours, in the transmission of a high-value solution, can reduce the leakage loss caused by hose damage to the greatest extent.

Recently, there have been occasional customer consultations. After the peristaltic pump I bought has been placed for a while, when I use it again, I feel that it is not as easy to use as before. Why is this? Here are some possible reasons and solutions. 1, Well-sealed The peristaltic pump is a precision instrument. It is placed in a humid environment, or there is dust, which will affect the normal use of the peristaltic pump, and even cause a circuit failure to start. Therefore, pay attention to keeping the peristaltic pump sealed in a ventilated and dry environment. 2, Check the problem If it is not used for a long time, check whether the roller in the pump head is flexible when using it again, whether the rotation is stuck, and whether there is any abnormal noise after starting the peristaltic pump for operation. Note: If you find that the roller cannot be rotated or it is difficult to rotate, do not use it forcibly. The motor will be damaged when the fault is serious, and it is recommended to contact us immediately to solve it. 3, hose preservation Peristaltic pump silicone tubes are commonly used consumables, and attention should also be paid to the storage method. If the silicone tube is in a humid environment for a long time, it will be damaged due to the dissolution of water-soluble substances and water in the silicone. If it is not used for a long time, it should be sealed and stored in a dry place.

The peristaltic pump is a new type of industrial pump, gradually accepted by various industries, the general peristaltic pump is composed of three parts: drive, pump head, and hose, as for how to support it, here and we share the place that needs to be paying attention to it. 1, determine the flow As long as the flow rate is determined, the selection range of the peristaltic pump will be greatly reduced. For example, the 600rpm flow range of the yZ1515X pump head is only 2280ml/min, but if kZ25 is used for 600rpm, there is 6000ml/min. Similarly, different pump heads naturally have corresponding drives or hoses. 2. Liquid state When determining the flow to know, the nature of the transmission fluid and its status, and is also an important factor to choose, such as liquid inside the particles or relatively thick it requires better elastic thick wall tube transport, transport liquid, it has the chemical corrosion resistance, then choose the corrosion-resistant hose, can choose to see if doubts are consulting us. 3. Work environment If the working environment needs explosion-proof, then we can only choose an explosion-proof peristaltic pump, or do not need the whole machine pump, need to be matched with the equipment, then do not need to buy the driver, consult us for OEM customization.

Liposuction this industry is also gradually rising with the development of society, also known as liposuction weight loss, and body sculpture, the use of machinery through the skin small incision deep subcutaneous fat layer will be absorbed fragments, to achieve the purpose of absorbing fat. Using negative pressure liposuction machine, shaped shock, absorb human body fat, is commonly used in obesity, or pathological obesity treatment with liposuction, liposuction machine work, needs to be stable, no pollution, easy to clean, and other requirements, so the peristaltic pump has become one of the main equipment of liposuction machine. Features of peristaltic pump working in liposuction machine: 1. Stable transmission When the liposuction machine is working, the peristaltic pump is stable in transmission, avoiding secondary damage to the human body. It has good matching performance with the machine, which is also the reason why the liposuction machine is willing to match the peristaltic pump. 2. No pollution Because only the hose touches the fat during transmission, it is easy to clean and sterilize and ensure aseptic cleanliness during work. 3, simple maintenance As supporting equipment of liposuction machine, maintenance is also very simple, only need to ensure the clean surface of the pump head, do not need other maintenance, according to different use frequency, regular replacement of peristaltic pump hose can be.

Requirements: A semi-liquid concentrate is required to be delivered at a flow rate of 8.0 mL/min. The installation space was small and the operator wanted the pump to have remote switching. Solution: A BT100M single-channel pump in the speed range from 0 to 100rpm, using a 1.6mm inner diameter pipe. The flow rate can be flexibly changed under the condition that the pump speed is always at a moderate level. Pharmed meets FDA and NSF standards while providing long service life and excellent performance when delivering semi-liquid concentrates. In addition, after setting the speed on the pump, the pump can be controlled remotely through the external control interface on the back of the fuselage. Application Example (Peristaltic pump vs gear pump) A quality control technician needs to draw drinks from a spectrophotometer sample pool. Flow rates range from 0.8 to 1.2 mL/min. The technician wishes to transfer a blank solvent simultaneously at the same flow rate. The advantages of the Rayford peristaltic pump: To replace the sample, only the pump pipe needs to be replaced; The dual-channel pump can transfer samples and blank solvents simultaneously. Different flow rates can be achieved by changing pump tube size or adjusting driver speed; Disadvantages of gear pump: Carefully flush the pump before changing the sample; With double-channel function, technicians need to adjust and operate two respectively; Application of peristaltic pump in soft drink filling Requirements: A soft drink dispenser needs to deliver airless soda water to a densitometer at a rate of about 50 mL/min. This is a decisive step in the quality assurance process for bottling equipment. Solution: The BT100M precision pump with remote control can maintain the controlled flow rate of the filling machine without the need to purchase a digital model. Tygon? The high transparency of the pump tube makes it easy for the user to observe the fluid condition. The driver can be locked at the required speed, and then the pump can be switched on and off remotely. Application in dairy processing Application scheme: A dairy processor needs to deliver 30% hydrogen peroxide (H2O2) into a sterile canning system at relatively high back pressure (30 to 40 psi). The advantages of a peristaltic pump: H2O2 is compatible with the pump tube material, and the decomposition degree is controlled at a minimum. A steady flow rate can be maintained under the condition of back pressure; The service life of the pump pipe can be up to 3 months, minimizing the maintenance cost; IP66 protection level driver is the ideal choice for the dairy processing environment; Disadvantages of diaphragm pump: Hydrogen peroxide breaks down on metal to produce oxygen; There is backpressure, the diaphragm pump is difficult to work properly; If you are interested in the peristaltic pump or have any questions, please leave a message or contact us: www.crpump.com,support@crpump.com,15633705132

Peristaltic pumps, also known as constant flow pumps, are widely used in pharmaceutical, food and beverage, chemical, water treatment, laboratory, and other fields. It can transmit corrosive chemical reagents such as strong acid and alkali, and can also transmit viscous and sensitive fluids containing certain particles. Peristaltic pumps are very popular in the pharmaceutical industry for their high precision, low flow rate, ability to transfer highly viscous liquids, and non-contamination and corrosion-free pump tubing types. Whether it is a laboratory peristaltic pump or an industrial peristaltic pump, it is the transmission accuracy of the peristaltic pump that determines the efficiency of the peristaltic pump at work. However, the high accuracy of peristaltic pumps requires good drivers, peristaltic pump heads, and hoses. The peristaltic pump hose is the main component of the peristaltic pump, and its performance directly affects the accuracy and stability of the peristaltic pump flow. Many factors affect the life of the peristaltic pump hose, such as the speed of the peristaltic pump drive, the material of the hose, and the pressure tube gap between the pump head roller and the arc. Fatigue damage is the main manifestation of a hose rupture, and the operating speed of the pump head needs to be adjusted. when choosing a peristaltic pump, you should try to choose a pump head with a larger flow rate, or you can run at a slower speed, thereby extending the life of the hose. The choice of material plays an important role in the overall performance of the peristaltic pump hose. Domestic hoses are generally food-grade silicone hoses, with a lifespan of about 200 hours under the condition of uninterrupted operation at 600 rpm, while under the same conditions, imported hoses can achieve a long life of more than 1200 hours. In contrast, the price of imported hoses will be much higher than domestic ones. However, imported hoses also need to be selected according to the actual use, and not all imported hoses have a long service life. The service life of imported hoses of some materials may be much shorter than that of domestic hoses. Special Occasion. In addition, the size of the pressure tube gap and the uniformity of the pressure tube gap also affect the life of the peristaltic pump hose. For example, whether the curve of the arc is uniform, the machining error of the roller and the wheel, and the assembly error of the center of the roller and the center of the arc. If the gap between the pressure pipes is not uniform, to ensure the airtightness of the pump head, the position at the minimum pressure will be subject to no air leakage, so that the other places will be overpressured (the gap will be smaller than the normal value), which will make the hose The local lifespan is reduced. With the development of the market, the corrosion-resistant peristaltic pump supplements the defects of the traditional peristaltic pump according to the characteristics of the medium (such as corrosiveness). The transport of corrosive media is often accompanied by high temperature, high pressure, or impurities, which will further affect the life of the pump. Various chemicals and organic solvents are often accompanied by an increase in temperature during the transfer process, and many media also have high viscosity and large specific gravity due to various processes. These phenomena have produced a severe test for the pump. Chuangrui peristaltic pump, its YZ1515 pump headshell is made of PPS polymer material, and the pipe fittings in contact with the internal material is a high-function engineering plastic hose, which can well solve the problem of chemical transportation. And its long service life, easy to replace the hose. It can completely solve various problems of ordinary corrosion-resistant pump products, thereby reducing production and engineering costs, and improving system stability. This equipment has outstanding advantages and is gradual wins market attention.

In the industry, there are many complex mechanical instruments, and the auxiliary projects are progressing steadily, including the automatic non-toxic and non-toxic measuring instrument for insoluble substances introduced this time, which is specially designed to discharge and store waste liquids; large-scale precision instruments for adsorption and filtering of toxic volatiles, This instrument is used in electrical, pipeline, construction and other fields, and the peristaltic pump is also a part of its key supporting settings. Non-toxic automatic analyzer for insoluble matter The automatic analyzer is a kind of testing instrument that can be automatically cleaned and dried automatically after the experiment is completed through the automatic measuring system of reagents, automatic heating system, and automatic stirring system. By placing toluene and quinoline inside the instrument, all processes such as sampling can be completed automatically without human intervention. However, both quinoline and toluene are harmful to the human body. Therefore, in the process of transferring these two stock solutions, it is necessary to ensure the safety of sealing and the accuracy of the transmission amount. To ensure the above two important factors, the peristaltic pump has become one of the important supporting equipment of the automatic analyzer. Peristaltic pump features 1. Sealed and pollution-free Thanks to the unique operating principle of the peristaltic pump, only the pump tube is really in contact with the stock solution, and will not touch other mechanical parts, which ensures the accuracy of the experiment. 2. Stable transmission The peristaltic pump squeezes the hose alternately through rollers. The flow rate is determined by the inner diameter of the pump tube and the geometry between the rotors. Therefore, except for high-viscosity fluids, the "pillow fluid" between the pump heads can always remain stable. transmission. 3. Simple maintenance Based on the working principle of the peristaltic pump, the loss of the peristaltic pump is generally only the hose, and because of this, it is only necessary to replace the hose regularly, avoiding unnecessary trouble. 4. Can be customized The peristaltic pump can be customized according to different equipment to meet different work requirements to the greatest extent. Whether it is a complete machine or a single pump head, it can be freely matched. The above is the reason why the toluene insoluble non-toxic automatic analyzer is used as an important accessory.

It is understood that peristaltic pumps are the fastest growing technology in the world. Usually, chemical corrosion products corrode the valves, seals, rotors, and moving parts of diaphragm pumps and single-screw pumps, resulting in pump damage and production interruptions. Whereas peristaltic pumps have no valves, no leaks, and no mechanical parts in the product line. The fluid is only in contact with the inner wall of the hose or the pipe, and the cost of the pipe is very low, it is low maintenance, and it is very durable. The principle of operation of a peristaltic pump is very simple. A length of hose or tube is placed along with a fixed pump casing and compressed from the outside by rollers or lugs (hose pumps). As the rollers or nubs move along the outside of the tube, fluid is pushed towards the outlet; as the hose or tube behind the nubs returns to its original shape, more fluid is drawn into the pump. The heart of the pump is the hose or tube. It has a long service life and is resistant to corrosion by concentrated acids, alkalis, and solvents. The flow rate of the peristaltic pump is proportional to the rotational speed. The peristaltic pump has no check valve, which eliminates the source of inaccurate metering, so the phenomenon of steam lock will not occur. With valves in diaphragm pumps, there is a risk of jamming, and clogging (due to corrosion of the valve ball or seat), resulting in inflow changes that disrupt the consistency of the final product or result in differences in product quality. The turndown ratio (maximum flow/minimum flow) or flow range of peristaltic pumps is unmatched by other pumps. By simply controlling the rotor speed, the turndown ratio can be scaled up to 1 million by equipping with tubes of different sizes. Diaphragm pumps can usually only achieve a speed ratio of 20:1 under the control of conventional controllers. Although the stroke length of the diaphragm can be adjusted to increase the turndown ratio, the metering accuracy will be greatly reduced in the case of short strokes. When a large flow range is required, two or more diaphragm pumps are usually used to control the flow, which can be solved by a peristaltic pump. The initial investment cost of a peristaltic pump may be slightly higher than other pumps, but the installation, maintenance, spare parts, and related auxiliary equipment of other pumps can be very expensive, and in terms of life cycle costs, peristaltic pumps are superior. In a peristaltic pump, the tube or hose is the only wetted part, requiring little maintenance, no expensive seals to replace, no valves, and no rotors or stators to wear out. It's just the hose or tube that needs to be replaced regularly. Industrial-grade peristaltic pumps deliver thousands of hours of reliable operation. The process of replacing a hose is usually less than an hour, and in some cases, only a few minutes, before the hose fails due to fatigue. Moreover, the hose can be changed quickly and safely without any special tools. This is significantly less than the 4-6 hour repair time required for a diaphragm or single screw pumps, not counting the extra time they take to move, transfer and reinstall. The cost of the hose is very low compared to the repair of a diaphragm pump or a single screw pump, where replacement wet-end parts such as ball valves, rotors, and stators can account for up to 75% of the initial pump purchase cost. Peristaltic pumps do not require the installation of auxiliary equipment. Diaphragm pumps require a back pressure valve and a vent valve to ensure proper operation of the internal check valve. Single screw pumps typically require dual mechanical seals, flushing systems, dry running protection, and built-in check valves. With peristaltic pumps, the cost of these auxiliary components can be eliminated. Many positive displacement pumps require the additional purchase of a separate control board or frequency converter for variable flow metering. If the flow range needs to be increased, the cost and complexity will also increase. The peristaltic pump is self-priming (up to approx. 10 meters), which increases operator safety as the handling of hazardous chemicals is reduced. This kind of pump also has a certain dry running function, which is very suitable for the emptying of storage tanks or other unmanned operation occasions. Peristaltic pumps can also run in reverse and can be used to drain pipes or remove blockages by simply changing the direction of rotation. As a result, the functions and advantages of peristaltic hose pumps will gradually become known. New peristaltic pumps are fast becoming the primary choice for aggressive chemicals.

Now the epidemic has been repeated. We all feel that this year is also quite difficult. I hope the epidemic can pass as soon as possible. Because of the epidemic, we are no longer unfamiliar with nucleic acid reagents, so do you know how to make this reagent? What role does the peristaltic pump play? Share it with you here. What is nucleic acid? In general, the nucleic acid is a general term for DNA and RNA, because viruses are mainly made up of genetic material and proteins, novel Coronavirus is an RNA virus. You can tell if a person is infected by a virus by testing their throat swab sample for viral RNA. With real-time fluorescent reverse transcription-polymerase chain reaction (RT-PCR), the nucleic acid of the sample taken is extracted, and then the DNA is replicated in large quantities by the nucleic acid amplifier, and if it contains novel Coronavirus nucleic acid, then the fluorescence signal will be detected by the instrument, and so the Novel Coronavirus will be detected. Such detection reagents need to be filled in large quantities, and a peristaltic pump is an indispensable part of the filling part. It is controlled by the automatic filling system of the peristaltic pump, the filling accuracy error is small, and the filling head will not drip or overflow. Secondly, in the whole process of reagent transmission in the filling system, the reagent only touches the pump tube, which meets the requirements of safe and pollution-free production. In the whole filling process, only the pump tube will produce losses, so it is very simple to maintain, and the pharmaceutical can replace the pump tube regularly.

Under the strict production demand, the advantages of the peristaltic pump gradually appear: Many foods and beverage manufacturers began to turn to peristaltic technology to meet their core needs, namely to limit pollution, reduce waste and ensure cleanliness. CR peristaltic pump creates customer value with professional services and provides great supporting support for efficient production in food processing. safety and sanitation Peristaltic pump technology in its design has the characteristics of health, the flow channel only hose (silica gel tube) and the medium to be transported in contact, to avoid the fluid and pump mutual pollution, health level can fully meet the requirements of drugs, food-grade Micro damage to the transmission The working principle of micro-loss transmission is that the liquid in the pump pipe is squeezed by the roller, and the liquid moves along the roller to push the liquid forward. With low shear force, the sensitive and reactive medium can be gently sucked to minimize the transmission damage of the fluid. Save labor cost Online cleaning (CIP) and online sterilization (SIP) are essential in food manufacturing. Peristaltic pumps can clean up the production line without further dismantling the pump, greatly saving time and reducing costs. cost reduction Food-grade silicone tubes can be disinfected using all conventional methods, including radiation, steam, and chemical solutions, and the tubes are easy to replace, reducing the cost of disinfection regulations. To prevent backflow The peristaltic pump works by extruding flexible hose elements with a rotating roller. After each runner has been rolled, the hose element returns to form and creates a vacuum to draw the object or fluid in. This has the effect of volumetric displacement, preventing backflow and eliminating the use of check valves when the pump is not operating.

A cell bioreactor is a scientific instrument mainly used in pharmacy, bioengineering, and other fields. It is mainly used for the cell culture of animals and plants. Because of the different culture methods, it is divided into batch type, semi-continuous type, continuous type reactor, etc. Wait. It is the key equipment for transforming biotechnology into products and productivity. When the cell bioreactor is in use, it needs a pump for feeding the equipment, acid-base, foam, or liquid collection. Generally, a peristaltic pump is used to match the equipment, as shown in the figure below. Why match with a peristaltic pump? 1.Because the peristaltic pump can be freely customized according to the needs of customers, it can also be freely controlled by the program of the supporting equipment. 2.Because the operating principle of the peristaltic pump is to squeeze the hose through the roller so that negative pressure is formed inside the tube to absorb the liquid and transmit it, so only the hose really contacts the liquid raw material, which easily avoids the contamination of the raw material. As shown in the figure, the clear liquid between the reactor and the column is transported by a hose. 3.Compared with other pumps, it is more convenient to maintain and replace the hose regularly.
