由于离心泵的工作原理和特性，其泵组运行启闭方式一般为电机直接启动，水泵闭阀启动，关阀停泵，该方式对机组及配套水力机械设备产生较大振动。根据某大型泵站离心泵组运行实际情况，对该泵组启动方式进行优化，减轻了振动现象。

Due to the centrifugal pump working principle and characteristics, the mode of on - off operation of the pump unit usually is directly starts the asynchronous motor, opening valve and the pump starts, closing valve the pump stops. The operation mode generates large vibration to the unit and supporting hydraulic mechanical device. In this paper, the starting mode of the pump unit is optimized with the goal of reduce the vibration according to the actual operation situation of a major water supply pumping station's centrifugal Dump unit.
