大功率高速同步电机暖机进程及顶升油泵系统测试分析

根据长输管道大功率高速同步电机暖机进程及顶升油泵系统现状,对机组暖机进程进行测试并跟踪分析,发现暖机进程与同步电机过临界转速时振动值的相关度不高,暖机时间可以进行减少或取消。对同步电机顶升油泵系统进行测试,分析取消顶升油泵时同步电机振动、温度、起停机时间等的变化情况。试验结果表明,可降低顶升油泵联锁停泵转速。

Test and Analysis for Warmup Process and Jacking Oil Pump System of High Power High Speed Synchronous Motor

According to the warmup process and jacking oil pump system of high power high speed synchronous motor in long distance pipeline, the unit warmup process was tested and analyzed. The warmup process was not highly correlated with the vibration value of the synchronous motor near the critical speed point, and the warmup time could be reduced or cancelled. The synchronous motor jacking oil pump system was tested, and the changes of the synchronous motor vibration, temperature, start stop time, etc. when the jacking pump was cancelled were analyzed. The results showed that the chain stop pump speed of the jacking oil pump could be reduced.
