蠕動泵主要由驅(qū)動器、軟管1、裝在轉(zhuǎn)子3上的滾輪2和外殼組成。在這些構(gòu)件中，軟管1用橡膠或塑料等彈性材料制成，其余則為金屬剛性件。蠕動泵的動作柔和，適用于不耐剪切的流體。這種泵的結(jié)構(gòu)簡單可靠，也是泵送中等流量、中等壓力的磨損性、易損及腐蝕性流體的理想選擇。由于只有軟管與流體接觸，所以它們的維護也很簡單。
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.
蠕動泵的工作原理是利用了一根軟質(zhì)的彈性體管承受變形并恢復到最初形狀的能力。蠕動泵就像用手指夾擠一根充滿流體的軟管，隨著手指向前滑動管內(nèi)流體向前移動。蠕動泵也是這個原理只是由滾輪取代了手指。通過對泵的彈性輸送軟管交替進行擠壓和釋放來泵送流體。就像用兩根手指夾擠軟管一樣，隨著手指的移動，管內(nèi)形成負壓，液體隨之流動。
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.
