Peristaltic pump brief introduction to the working principle

【Pump Network in Asia】 Peristaltic pump is a kind of pump equipment with features of non-pollution, high precision, good sealing and easy maintenance. Such products are widely used in China's chemical industry, metallurgical industry, papermaking industry, food industry and petroleum industry Use, then let us learn more about these products through the peristaltic pump working principle. Peristaltic pump works Peristaltic pump is like a finger squeeze a hose filled with fluid, as the fingers slide forward the fluid within the tube to move forward. Peristaltic pump is also the principle just replaced by the roller finger. The fluid is pumped by alternately squeezing and releasing the pump's flexible delivery hose. Just like squeezing a hose with two fingers, as the finger moves, a negative pressure builds up inside the tube and the fluid flows. A peristaltic pump is a section of tubing between two rollers that forms a "pillow" fluid. 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 of the speed of the pump head and the size of the "pillow" and the number of "sleepers" produced per revolution of the rotor. The size of the "pillow" is generally constant except when pumping particularly viscous fluids. Pumps with a larger "pillow" volume, when compared to pumps with the same rotor diameter, have larger volumes of fluid delivered per revolution of the rotor but also greater pulsations. This is the case with membrane valves. A smaller "pillow" volume pump, on the other hand, delivers less volume of fluid per revolution of the rotor; moreover, a small, "pillow" that is formed quickly and continuously produces a smoother fluid flow. This is similar to the work of the gear pump Through the above analysis and introduction of the peristaltic pump working principle, I hope for everyone in the use of peristaltic pump to provide help. With the rapid development of water treatment industry, pharmaceutical industry, medical device industry and other industries, the demand for peristaltic pumps will certainly be more vigorous. How to make peristaltic pumps more suitable for the needs of this market and we need to continue exploring. This article belongs to Industrial Internet (Xiamen) Technology Co., Ltd.
