摘要
离心泵是国民经济各部门必不可少的通用机械,耗电量较高,因此泵的节能意义十分重大。离心泵为无底阀运行,计算了离心泵取消底阀前后各项阻力损失,选择吸水装置及其设计,并进行经济性分析。
The centrifugal pump is the essential general machinery in the national economy various departments, and the power consumption is high, therefore pump energy conservation significance is very significant. The centrifugal pump without bottom valve movement, then calculates the lose before and after the centrifugal pump cancel the bottom valve, choice absorbing water installs and carries on the design and the efficient analysis.
