离心泵有立式、卧式、单级、多级、单吸、双吸、自吸式等多种形式。离心泵是利用叶轮旋转而使水发生离心运动来工作的。水泵在启动前,必须使泵壳和吸水管内充满水,然后启动电机,使泵轴带动叶轮和水做高速旋转运动,水发生离心运动,被甩向叶轮外缘,经蜗形泵壳的流道流入水泵的压水管路。1.泵不吸水,但真空表显示高度真空。故障原因:底阀未开或淤塞;吸水管阻力太大;吸水高度太高。排除方法:打开或清洗底阀;清洗或 Centrifugal pump vertical, horizontal, single-stage, multi-stage, single suction, double suction, self-suction and other forms. Centrifugal pump is the use of impeller rotation and centrifugal motion of water to work. Before starting the pump, the pump housing and suction pipe must be filled with water, and then start the motor so that the pump shaft can drive the impeller and water to do high-speed rotation movement. Centrifugal movement of water occurs and is thrown to the outer edge of the impeller. Road into the pump pressure water pipeline. 1. The pump does not absorb water, but the vacuum gauge shows a high degree of vacuum. Cause of failure: the valve is not open or blocked at the end; suction pipe resistance is too large; absorbent height is too high. Remedy: Open or wash the bottom valve; wash or
