带负荷启动工况下泵系统的瞬变特性研究

Study of Transient Characteristics in Pump System When Start With Load

以实验研究为基础 ,论述了在失压工况下 ,泵的瞬变工况 ,泵上下游管系内的瞬变流动特性及系统上游压头和管系长度对失控工况系统特性的影响 。

This article based on experiment discusses the follows: the transient condition of the pump, the transient flow characteristics between the upper reaches and the lower one in the pipeline and the influences on the system characteristics come from the pressure of the upper reaches and the length of the pipeline. It can be consulted in the design and application of hydraulic system.
