摘要
在用注气阀消减泵系统两处断流弥合水锤实验基础上,本文探讨了不同初速、停泵或关阀速度时,注气阀径及位置对消减两处伴有水柱分离的水锤升压作用规律;探索了非满流状态下数值解法,编制的电算程序计算结果与实测曲线吻合良好。
On the basis of experiment on Control of water column separation auo- mpanying transiet flow at two points by entrapped air,the paper studi- ed the influence laws of valve-diameter,position on reducing the wat- er hammer accompanying transiet flow in pump system at two points in the condition of varous velocities of pump-stopping(or valve-shutting), analysed the numerical method of the wnsteady flow-in open channels, the computer programs are complied and th computer solution is in good correspondance with the experiment.
