工作原理
working principle
通过挤压软管实现液体的输送，因此这种泵输送的液体在泵内只经过软管，没有死角，因此极易清洗，不会产生残留，非常适合于需要洁净输送的用途。再因为蠕动泵每转一圈都会输出固定量的流体，因此蠕动泵也非常精准，可以通过调速和计时的方式实现精确的计量输送。蠕动状态的软管就像人的肠道一下推动管内的流体，因此不会对流体产生挤压和破坏，不像离心泵的高速叶轮会对流体中的固体产生叶轮旋切。特别适合输送类似橙子果粒一样的物料。
The liquid is conveyed by squeezing the hose. Therefore, the liquid conveyed by this pump only passes through the hose in the pump, and there is no dead corner. Therefore, it is very easy to clean and will not produce residues. It is very suitable for the purpose of clean transmission. Moreover, because the peristaltic pump will output a fixed amount of fluid every revolution, the peristaltic pump is also very accurate, and accurate metering and transmission can be achieved by speed regulation and timing. The peristaltic hose is like a human intestinal tract pushing the fluid in the pipe, so it will not squeeze and destroy the fluid. Unlike the high-speed impeller of a centrifugal pump, it will spin and cut the solids in the fluid. It is especially suitable for conveying materials similar to orange fruit.
