低扬程水泵装置停泵过渡过程的近似计算

Numerical Calculation of Hydraulic Transients for a Low-head Pump Station during Its Suspending Period

根据低扬程泵装置管路特性、水泵机组的动力学特性和停泵过渡过程中泵系统能量守恒原理以及泵相似理论 ,并结合现场实测停泵过渡过程曲线的特征点 ,提出了低扬程泵站停泵泵工况动态特性计算的数学模型。

A mathematical model for calculation of dynamic characteristics of a low-head pump station during its suspending period was developed based on the pipeline characteristics of the pumping system. The principles of the energy conservation and the similarity theory combined with the eigenpoints in the hydraulic transients curves measured during suspending period were employed in this modeling procedure.
