离心泵原理[0]

Posted on 2023年11月14日 by

离心泵的工作原理就是离心运动,离心其实是物体惯性的表现,比如雨伞上的水滴,当雨伞缓慢转动时,水滴会跟随雨伞转动,这是因为雨伞与水滴的摩擦力做为给水滴的向心力使然。但是如果雨伞转动加快,这个摩擦力不足以使水滴在做圆周运动,那么水滴将脱离雨伞向外缘运动,就象用一根绳子拉着石块做圆周运动,如果速度太快,绳子将会断开,石块将会飞出,这个就是所谓的离心。

离心泵工作时,高速旋转的叶轮叶片带动液体转动,将液体甩出,从而达到输送的目的。离心泵在工作前,泵体和进水管必须罐满液体形成真空状态,当叶轮快速转动时,叶片促使液体很快旋转,旋转着的液体在离心力的作用下从叶轮中飞去,泵内的液体被抛出后,叶轮的中心部分形成真空区域,外部的液体在大气压力的作用下通过管网压到了进水管内。这样循环不已,就可以实现连续输送。
