首先我们先介绍一下软管泵，软管泵又称蠕动泵。为了泵体污染流体或流体污染泵体的危险性，整个泵的装置中只有软管与介质接触。在一般场合下，软管泵使用的都是天然橡胶的软管。内层和外层都是完整光滑的天然橡胶，其目的是很强防磨损。适用于腐蚀性不高但磨损性很大的如泥浆以及无机物等等介质。而且一般适用于脂肪、油类或油脂的介质，以及有机化学物质。内层是橡胶，而外层是天然橡胶或者是复合橡胶。

First of all, lets introduce the hose pump, which is also called peristaltic pump. In order to eliminate the danger of the pump body contaminating the fluid or the fluid contaminating the pump body, only the hose in contact with the medium in the entire pump device. In general, hose pumps use natural rubber hoses. The inner and outer layers are completely smooth natural rubber, the purpose of which is to prevent abrasion. It is suitable for mediums that are not corrosive but very abrasive, such as mud and inorganic substances. And generally suitable for fats, oils or oils, and organic chemicals. The inner layer is rubber, while the outer layer is natural rubber or composite rubber.

 

软管泵分类<br />
软管泵分单作用及双作用两种型式。<br />
单作用式软管泵在活塞往复运动的一个循环中仅完成一次吸排水动作。而双作用式软管泵每往复一次完成两次吸排水动作。若按软管泵的缸数分类：有单缸、双缸及三缸3种。<br />
污水软管泵是单级单吸立式离心泵,主要部件有蜗壳、叶轮、泵座、泵壳、支撑筒、电机座、电动机等组成。蜗壳、泵座、电机座、叶轮螺母是生铁铸造、耐腐蚀性较好，加工工艺方便。叶轮为三片单园弦弯叶,选用半封闭叶轮,并采用可锻铸铁、所以强度高,耐腐蚀;加工方便,通过性好,效率高。为了减轻重量和减少车削量、泵轴是优质碳素钢冷拉园钢制造。软管泵座中装有四只骨架油封和轴套,防止轴磨损,延长轴的使用寿命。<br />！
