多台离心泵并联工作时叶轮切割

Incising of Multiple Paralle;-Connected Centrifugal Pump Runners

针对供排水车间多台并联工作的离心水泵实际运行参数大大偏离设计工况点的问题 ,在不更换泵的前提下 ,分析并联工作的离心水泵特性 ,通过计算后对三台泵叶轮进行了切割 ,从而改善泵的运行状况 。

In the light of the fact that the actual running parameters of paralled-conneeted centrifugal pumps are not in keeping with initial design,without changing pumps,characteristics of parallel-connected centrifugal pump are analyzed,and then after computations,runners of three pumps are incised.As a result,running conditions of pumps are bettered and actual current drain of pumps is reduced.
