大中型泵站机组特性测试与诊断系统研究

Research on Large and Medium-sized Pump Station Unit Property Test and Diagnosis System

分析总结了国内外对泵站水泵机组测试与诊断方法研究现状,结合我国泵站工程的实际情况,研究开发了大型泵站机组特性测试与诊断系统,系统可以对水泵机组的扬程、流量、转速、功率等运行特性进行测试,并对测试数据进行分析处理,绘制相关性能曲线,掌握机组运行状态;同时系统可以实现水泵机组的振动、摆度、噪声等参数的在线监测,根据监测数据进行机组早期故障分析和预报,实施机组预知维护。系统通过工程实例验证,效果良好,具有一定的实用意义。

This paper analyzes the test and diagnosis methods of the pump unit at home and abroad, according to the actual engineer- ing situation of pump stations in our country. Large and medium-sized pump station unit property test and diagnosis system is devel- oped, the system can test pump unifs operating characteristics as pumping head, flowrate, rotate speed, power and so on. The sys- tem analyzes, processes the test data and draws related performance curves and have mastered the unit running status. The system can also realize monitors pump unit＇s vibration, throw, noise and other parameters on--line, according to the monitoring data for the early failure analysis and forecast unit and implement unit prescient maintenance. The system through the engineering example veri- fies that the effect is good, so the system has certain practical significance.
