蠕动泵主要由驱动器、软管1、装在转子3上的滚轮2和外壳组成。在这些构件中，软管1用橡胶或塑料等弹性材料制成，其余则为金属刚性件。蠕动泵的动作柔和，适用于不耐剪切的流体。这种泵的结构简单可靠，也是泵送中等流量、中等压力的磨损性、易损及腐蚀性流体的理想选择。由于只有软管与流体接触，所以它们的维护也很简单。

The peristaltic pump is mainly composed of a drive, a hose 1, a roller 2 mounted on a rotor 3 and a shell. In these components, the hose 1 is made of elastic materials such as rubber or plastic, and the rest is metal rigid. The action of the peristaltic pump is soft and is suitable for the fluid that is not resistant to shear. The pump has a simple and reliable structure, and it is also an ideal choice for pumping medium and medium pressure wear, fragile and corrosive fluids. Because only the hose is in contact with the fluid, their maintenance is also very simple.

蠕动泵的工作原理是利用了一根软质的弹性体管承受变形并恢复到最初形状的能力。蠕动泵就像用手指夹挤一根充满流体的软管，随着手指向前滑动管内流体向前移动。蠕动泵也是这个原理只是由滚轮取代了手指。通过对泵的弹性输送软管交替进行挤压和释放来泵送流体。就像用两根手指夹挤软管一样，随着手指的移动，管内形成负压，液体随之流动。

The working principle of a peristaltic pump is the ability to take advantage of a soft elastomer tube to withstand deformation and restore to its original shape. A peristaltic pump is like squeezing a fluid filled hose with a finger, and the fluid moves forward as the finger moves forward. The peristaltic pump is the same principle that the finger is replaced by a roller. The fluid is pumped through the alternate extrusion and release of the flexible hose of the pump. It is like squeezing a hose with two fingers. With the movement of the finger, a negative pressure is formed in the tube, and the liquid flows.
