Cavitations of water pump and its installation level 离心式水泵的汽蚀与安装高度
Reason and balance method of the axial propulsive force of the centrifugal pump 浅析离心式水泵产生轴向推力的原因及其平衡方法
Centrifugal water pump 离心式水泵
The cooler designed is a pipe - shell type cooler and the water pump driven by direct current servo motor is an away center type pump 设计的冷却器是管壳式,水泵采用直流伺服电动机带动的离心式水泵。
A test system was developed and an l9 ( 3 ^ 4 ) orthogonal experiment design was used to test the pump efficiency under different flow rates , lifts , electric voltages and currents 并设计了试验系统,采用l9 ( 3 ^ 4 )正交试验,以离心式水泵效率为试验指标,进行了离心式水泵的流量、扬程、电压和电流的测量。
