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.

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

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 t

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 fo

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 cour

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.

Fermentation tank mainly refers to the production of experimental equipment used for cell culture, pharmaceutical production, animal and plant tissue culture, microbial fermentation production, biological product preparation, sewage treatment, and other experiments, and production to provide a reaction environment. For example, cell culture fermenters are mainly used for animal and plant cell culture, microcarrier culture, genetically modified pharmaceutical engineering, etc. At present, there are many applications in the fields of life science and biopharmaceuticals, and it is mainly used in laboratory sample development and culture. How is the peristaltic pump applied to the fermenter? In the two parts of the raw material configuration and product separation and recovery of the fermenter, the raw liquid transportation will be involved. The transportation process requires sealing and pollution-free, simple maintenance, and good compatibility with machinery, and the peristaltic pump can meet all the above requirements. 1. Transmission method During the transmission process of the peristaltic pump, only the pump tube is in contact with the raw liquid, and the sealing performance is excellent. 2. Good adaptability The peristaltic pump is supported by machinery and can be produced according to your requirements to meet your different needs. 3. Simple maintenance Because of the principle of peristaltic pump operation, the consumables of the peristaltic pump are generally only peristaltic pump tubes, which only need to be replaced regularly, and the cost is low.

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

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.

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:

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

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. How

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 r

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.

A mosquito repellent net refers to a kind of mosquito net with a mosquito repellent effect. Different from an ordinary mosquito net, a mosquito repellent net has mosquito repellent ingredients, so it can repel mosquitoes and even kill insects. Mosquito repellent nets are mainly divided into three types: 1. Drug-dipping type 2. Coating type 3. Polymer injection type, peristaltic pumps are mainly used in coated mosquito nets. In the production process of mosquito repellent nets, the customer uses Chuangrui peristaltic pumps to quantitatively and stably transmit the mosquito repellent liquid and the adhesive, and then evenly coat the mosquito nets. Mosquito function.

Food production, not only has a very high standard of health and safety, and the damage transmission is also very important, such as dairy, cereal drinks, and fermentation additives transmission, not only to ensure the health of the environment, colleagues can carefully make transport processing. 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.

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

The extraction we usually say, the full name is called solvent extraction, is a unit operation that uses the different solubility of the components in the system to separate the mixture. In the course of the experiment, the method of transferring the solute substance from one solvent to another by using the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents. By extraction, the desired substance can be extracted from a solid or liquid mixture. It is used in chemical, metallurgy, food, medical, and other fields. In the actual operation process, for example, when adding an extractant that is predicted to be insoluble in each other in the solution to be separated, it is necessary to ensure a certain proportioning coefficient to achieve successful proportioning. To ensure the accuracy of the solution volume or to perform batch operations, and to avoid the cumbersome manual addition, a peristaltic pump is often required. 1. Hygiene The

A vial, also known as a soda-lime glass injection bottle, is a small bottle sealed with a rubber stopper. The bottle body is generally made of glass. Used as iodine bottle injection bottle oral liquid bottle and other early plates. Nicklin is mostly used in its dress, hence the name vial. Vials are widely used in medicine, food, daily necessities, and other industries, and various types of equipment for filling vials require peristaltic pumps as important supporting equipment for production and use. For example, in a large-scale oral liquid filling machine, the multi-unit simultaneous filling of the filling system and the function of stopping filling when the bottle is missing can stably transmit the fluid and can perform batch filling more accurately. In the pharmaceutical, food, and other industries, because it is related to food, vial filling has very strict hygiene requirements, and peristaltic pumps can fully meet its strict hygiene requirements. 1. Hygienic and pollution-free Because of the unique operating principle of the peristaltic pump, in the process of raw liquid transportation, the raw material only contacts the pump tube and does not contact any other components, and is directly sent to the filling needle for filling, with good sealing performance, in line with pharmaceutical grade, food-grade hygiene standards. 2. Simple maintenance Also, because the raw material only contacts the pump tube, the maintenance of the peristaltic pump is extremely simple. The driver and pump head only need to be cleaned daily without additional maintenance. The pump tube is replaced regularly to avoid wear and tear affecting the transmission stability. 3. Wide application The peristaltic pump can be fully customized according to the needs of users, and the transmission flow range is wide, which is suitable for the transmission of different sizes of flow. If you a

After such a long time of development, the peristaltic pump is now active in many industries, and the process of using a peristaltic pump, often because of improper use, may let production to be affected, the life of the peristaltic pump to be affected and so on, here is to share with you what you need to pay attention to when using it! 1. Transport liquid Because of the operation principle of the peristaltic pump, the flow of liquid with different viscosity will also change. Therefore, when choosing a peristaltic pump, you must pay attention to consult your fluid transmission, so that Chuanggrui can better recommend the corresponding driver, pump head, and hose. 2, pay attention to maintenance Although the peristaltic pump supplies generally only hose, drive and pump head are used for a long time, but also depends on the severity of the working environment, if it is a relatively humid or dusty environment, pay attention to the peristaltic pump diaphragm protection, to prevent water vapor or dust from affecting the components. 3. Hose life Whether the choice of domestic hose or imported hose, is used to have a service life, pay attention to the hose service time, timely replacement, if the hose grinding lead to liquid leakage, even cause roller corrosion, dead, serious burning motor. 4, pay attention to suction and lift Suction range refers to the vertical height from the horizontal position of the liquid level to the pump head, and

E-cigarettes have a much shorter history than cigarettes. They are only a few decades old, but they come in a staggering variety of flavors, including 7,000 to 8,000, and even durian flavored oil. How can I put it? Everyone has different hobbies. Principle of smoke oil The composition of smoke oil is very simple, there are only four kinds in total, that is, propylene glycol (PG), vegetable glycerin (VG), nicotine, and edible essence. Propylene glycol is an organic compound, under normal conditions is a colorless viscous liquid, slightly sweet, in the smoke oil as a carrier of flavor, can increase the taste and throat feeling. Vegetable glycerin It is a water-soluble solution extracted from natural plant materials. Under normal conditions, it is sticky and slightly sweet. Vegetable glycerin is mainly responsible for producing fog in the smoke oil. nicotine I don't need to say more about this stuff. It's what makes cigarettes addictive. It's a throat-throb. Toxic in contact with skin. Edible flavor It's important for smoke oil because all the flavors come from different ways of making it, so the recipe is very complicated. Peristaltic pump in which the application: Generally, the production of tobacco oil may only be prepared to measure tools and elect
