1000MW机组凝结水泵变频改造后振动处理

Treatment of vibration of 1 000 MW unit condensate pump after variable frequency reformation

以广东大唐国际潮州发电有限责任公司1000MW机组为例,论述了凝结水泵由工频改为变频后共振问题的处理过程,指出了有效解决途径,为凝结水泵长周期、安全、可靠运行提供了保障。

Taking the 1000 MW unit of Guangdong Datang International Chaozhou Power Generation Company Limited as example,the treatment process of resonance of die condensate pump after its driving power source had been changed to variable frequency power source instead of 50 Hz power source was expounded.Effective solving way was point out,which provides guarantee for condensate pump to operate safely,reliably and continuously in long period.
