摘要
通过分析大气压力对离心式水泵补水能力 ,建立了一个估算水泵允许吸上真空高度的数学模型 ,指出了高扬程水泵在实际排水扬程偏低条件下运行时 。
Through analysing the relation of atmosphere and centrifugal pump cavitation,this paper founds a model about estimating pallowable degree of suction vacuum of pump,puts forward the reason of high_cift pump can't pump water high enough or cavitation on the condition that pump high_lift is lower and its solving method.
