Peristaltic pump silica gel tube is also called peristaltic pump hose. It uses the platinum vulcanization process for vertical extrusion molding, which eliminates the precipitation problem often encountered in other vulcanization methods. There is a great difference between the peristaltic pump hose and the ordinary silica gel tube. 1, because the silica gel tube is always squeezed in the process of use, so it should have the characteristics of not easy deformation and high resilience. The silica gel tube used by the Leifer pump is made of the high-purity wear-resistant silica gel material, which has the characteristics of high transparency, high-temperature resistance, and 90% resilience. 2, pump transmission characteristics for precision transmission, for peristaltic pump silica gel tube diameter and wall thickness size requirements are very precise, because the size of the inner diameter directly affects the flow rate of pumping liquid, thus affecting the size of the pump flow;

The peristaltic pump can be called a constant current pump, which is a kind of constant current pump, because the conveying precision can reach up to 0.5%, so it plays a role of constant current. The specific analysis is as follows: The principle of the peristaltic pump is that the runner presses the pump tube and rotates to push the fluid in the tube forward to generate fluid flow, just like using two fingers to squeeze a hose filled with liquid, with the fingers When moving, a negative pressure is formed in the tube and the liquid flows. Therefore, the peristaltic pump is a positive displacement pump. The liquid in the pump tube is pushed out by the runner of the pump head. After the runner leaves, the pump tube will stably rebound and suck in new liquid. Our peristaltic pump head produces a constant flow rate per revolution, and the flow rate will increase by the same amount every time the speed is increased per unit time. Therefore, the flow rate generated by the peristaltic pump at a specified rotational speed is constant. Since the peristaltic pump has this characteristic, the user often refers to the peristaltic pump as a constant current pump. The peristaltic pump is a kind of constant current pump. Because there are many kinds of pumps that can realize the function of constant current, such as diaphragm pump, plunger pump, screw pump, etc., the peristaltic pump is only one type of constant current pump. The peristaltic pump has the following advantages as a constant current pump: 1, clean and non-polluting: the fluid only passes through and contacts the peristaltic pump hose. 2, high precision: constant current, reproduction accuracy of up to 0.5%, flow can be precisely adjusted. 3, low shear: It is an ideal tool for conveying shear sensitive and aggressive fluids. 4, corrosion resistance: can transport a variety of fluids, such as organic melting machin

Peristaltic pump (peristalticpump), also known as the hose pump, is a new type of industrial pump, which is a product of the development of modern industry, widely used in pharmaceutical, food, chemical and other industries, the delivery of some sensitive, viscous , Corrosive, with grinding, high purity, and contains a certain granular material medium. Hoses are the only night-time requirement for peristaltic pumps, which work by squeezing the hose through rollers or briquettes, which means the pump can dry, self-priming, and handle high-viscosity, highly abrasive media. In addition, the hose as a separate unit, making the pump without sealing, so it is completely leak-free, very hygienic. And each revolution has a fixed output flow, which makes the peristaltic pump quantitative dosing applications have outstanding performance. This principle can be applied to all peristaltic pumps, then the pump head and drive part is the difference between peristaltic pump quality is the most important factor. Much like muscle contractions, relaxation can make blood flow in blood vessels, peristaltic pumps work by virtue of the pumping performance of several rollers that are alternately squeezed / released along a flexible tube. The pipe is squeezed fluid flow output, the pressure disappears after the tube relies on its own resilience to restore the original shape, the volume increases, resulting in a vacuum, inhaled fluid. This continuous action is the working principle of peristaltic pump. How Peristaltic Pumps Work Peristaltic pumps pump fluid by alternately squeezing and releasing the pump's flexible delivery hose. Like squeezing a hose with two fingers, a negative pressure builds up inside the tube as the fingers move, and fluid flows in. The peristaltic pump creates a "pillow" of fluid in the tubing between the two rollers. The size of the pillow depends on the inner diameter of the tubing and the geometry of the rotor. The flow rate depends on the product

The peristaltic pump constant-flow pump is used in the palm-handling machine. The most important function is to efficiently and accurately transfer the glue water needed by the palm-up machine to the specified position when the label is engaged. If the high-speed hand-held machine needs to use the glue when joining the label, the delivery of the glue is a problem. The previously used coating method such as the transfer coating of the runner has the following problems: 1, the glue contact parts, easy to contaminate the machine, not easy to clean. 2, the glue is not uniformly transferred, and the amount of glue is not easy to control. 3, the glue application process is troublesome, debugging is not convenient. Since the peristaltic pump only has a pump tube that contacts the glue, it can be continuously and accurately delivered to the part where the glue needs to be applied, so that the problem of the glue applied to the palm machine can be solved. The viscosity of the glue is very high, which is different from the general water-based fluid, so it can ensure high-efficiency and long-term stable glue application. The peristaltic pump constant flow pump is applied to the hand-held machine: 1. For very viscous liquids, use a slightly thicker peristaltic pump hose. 2. Appropriately use a peristaltic pump hose with a slightly larger inner diameter to further reduce the rotational speed of the peristaltic pump. 3. Reduce the speed of the peristaltic pump as much as possible, usually within 50 rpm. 4. Regularly check and replace the pump tube in advance to prevent the pump tube from rupturing. 5. When selecting a peristaltic pump, try to choose a peristaltic pump head that can withstand the strength of rubber and corrosion resistance. It is best to choose a peristaltic pump with flow display function and correction function.

Common problem of peristaltic pump common problem and answer CR peristaltic pump frequently asked questions and answers classification problem answer Understanding peristaltic pumps What is the working principle of theperistaltic pump ? The rotating hose is used to roll the flexible hose, and the fluid in the hose moves with the rotation of the wheel, just like the two fingers pinch the hose, and as the finger moves, the liquid flows. Peristaltic pump uses this principle to form a finger-like squeezing effect between the runner and the pressure block, generating a negative pressure to achieve the purpose of pumping. What are the advantages of

Peristaltic pump manufacturer teaches you how to improve the efficiency of peristaltic pump. Baoding Chuangrui Precision Pump Co., Ltd. is specialized in the development, production and sales of peristaltic pumps for more than ten years. According to its technical experience and customer feedback, Baoding Chuangrui Precision Pump Co., Ltd. Inc. summarizes the following considerations regarding the use of peristaltic pumps to provide their operational efficiency: (1) When the peristaltic pump is not working, loosen the pressure tube clamp to extend the life of the pump tube. The peristaltic pump relies on the natural rebound of the compression hose and the hose to generate suction and fluid. To maintain the long life of the pump tube, when not using the pump, lift the pump head clamp as much as possible so that the pump tube is naturally unstressed. State to extend pump life. (2) Under the premise of satisfying the flow rate when the peristaltic pump is selected, the pump speed can be reduced to less than 300 rpm. The flow rate of the peristaltic pump is generated by the rotation of the pump head. If the rotation is faster, the pump tube will be used for a shorter period of time, so when it is desired to use the pump tube for a longer period of time, the pump of a larger diameter can be selected as much as possible. Thereby reducing the speed of the pump. (3) The peristaltic pump is used on the pump head of the peristaltic pump, and the other connecting pipes are made of ordinary pipes. Extrusion tubes used on peristaltic pumps require good compressive resilience and tear resistance. Therefore, the material purity of these pump tubes is relatively high, and the wall thickness and shape accuracy are high, which causes the peristaltic pump tube to be expensive. Therefore, it is more economical to use a common pipe as the connecting pipe. (4) The peri

The characteristics of the peristaltic pump in the pharmaceutical industry and how to choose a good peristaltic pump, the application of the peristaltic pump is very wide. It is called the laboratory peristaltic pump used in the laboratory, and it is called the industrial peristaltic pump in the industrial field. The peristaltic pump is also used in the pharmaceutical industry. Although the name is different, the core technology is the peristaltic pump fluid transmission. What are the application characteristics of peristaltic pumps in the pharmaceutical industry? The peristaltic pump has the following characteristics in the dosing work: 1. The peristaltic pump only has the pump tube in contact with the liquid. 2. The transmission pressure of the low pressure peristaltic pump is within 0, 2 Pa. 3. The peristaltic pump cannot transport the solid-liquid mixture. 4. The peristaltic pump has higher accuracy than the traditional metering pump. 5. The maintenance of the peristaltic pump is more convenient and the cost is lower. 6, peristaltic pump zui large flow is low, want to transfer more flow should choose a larger flow of peristaltic pump, for this reason, peristaltic pump is also called micro peristaltic pump. 7. The peristaltic pump can transport highly viscous liquids. What should we pay attention to when choosing a peristaltic pump? When choosing a peristaltic pump, choose from the following aspects. 1. Peristaltic pump: The quality of the peristaltic pump itself determines the level of work efficiency, just like the atrium inside the blood circulation system. 2. Peristaltic pump head: The pump head of the peristaltic pump also has

Peristaltic hose pump silica gel tube is also called peristaltic pump hose. It uses the platinum vulcanization process for vertical extrusion molding, which eliminates the precipitation problem often encountered in other vulcanization methods. There is a great difference between the peristaltic pump hose and the ordinary silica gel tube. 1, because the silica gel tube is always squeezed in the process of use, so it should have the characteristics of not easy deformation and high resilience. The silica gel tube used by the Leifer pump is made of the high-purity wear-resistant silica gel material, which has the characteristics of high transparency, high-temperature resistance, and 90% resilience. 2, pump transmission characteristics for precision transmission, for peristaltic pump silica gel tube diameter and wall thickness size requirements are very precise, because the size of the inner diameter directly affects the flow rate of pumping liquid, thus affecting the size of the pump flow; 3, peristaltic hose pump applications are wide, in some industries will be used to transfer acid and alkaline solution, so its corrosion resistance is higher than other hoses. 4, for half of the pipe, there may be magazines and black spots in the pipe wall, but the pump with silicone tube can not appear, because it will cause wear and tear in the pumping process. 5. Wear resistance test of silica gel tube. The continuous working environment of the peristaltic pump will carry out repeated friction extrusion on the tube, and the moving time will be 600 RPM.

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 decreases. 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 fluid overflow: 1. Chuanggri peristaltic pump has low shear force, which can ensure the integrity and activity of biomolecules when pumping biological active substances. 2. Simple and sharp peristaltic pump to replace the hose, in the lab, different transmission solution, only through simple change meet the health level of hose, flow can be manually adju
