自吸式水泵简介及原理

水泵原理 卧泉泵业 771浏览 0评论

自吸式水泵,为水泵的一种。其原理是水泵启动前先在泵壳内灌满水(或泵壳内自身存有水)。启动后叶轮高速旋转使叶轮槽道中的水流向涡壳,这时入口形成真空,使进水逆止门打开,吸入管内的空气进入泵内,并经叶轮槽道到达外缘。通过反复循环,逐渐将吸入管路中的空气排尽,使水进入泵内,完成自吸过程。

内混式的自吸式水泵,工作原理与外混式自吸泵相同,其区别只是回水不流向叶轮外缘,而流向叶轮入口。内混式自吸泵在启动时,须打开叶轮前下方的回流阀,使泵内液体流回到叶轮入口。水在叶轮高速转动的作用下与吸入管来的空气相混合,形成气水混合物排至分离室。在这里空气排出而水又从回流阀返回到叶轮入口。如此反复进行,直至空气排尽,吸上水来。
