软管泵的工作原理

发布时间:2021-04-06 14:16 浏览次数:

软管泵属于蠕动泵的范畴。蠕动泵是转子式容积泵的一种,因其工作原理类似消化道以蠕动方式输送气、固、液三相介质而得名。软管泵与蠕动泵之间没有严格的区分。一般而言,蠕动泵指小流量(以毫升/分计)、低出口压力(不超过3kg/cm2),多用于卫生领域及实验室计量。

软管泵通过一对压辊沿着一根特制的橡胶管旋转,将橡胶管压扁,管子靠自身弹性在恢复原状的过程中产生真空将物料吸入泵腔,然后物料在压辊挤压下从管内排出。如此周而复始,物料不断的被吸入和排出。软管泵最大的优势在于:特有的无密封结构,无任何泄露污染,采用先进的滚动技术,压辊不需要任何润滑,自吸能力强并具有自清能力,能正反吸料。另一大特点是,浆料中含有固体颗粒不大于软管内径1/3的情况下不影响物料输送。
