AN EXAMPLE OF BEARING VIBRATION FOR MOTOR-DRIVEN FEED-WATER PUMP DUE TO UNSUITABLY INSTALLED PIPELINE
摘要
登封市热电有限公司210MW机组电动给水泵因进出水管安装不当引起给水泵和管道振动大
切开后进行重新布管焊接
振动值大幅度降低
给水泵运行正常。
Abstract
Serious bearing vibration of the motor-driven feed-water pump and its pipelines concerning 210 MW unit had occurred due to unsuitably installed inlet water pipe in Dengfeng City Thermal Power Co Ltd. After cutting apart
the inlet water pipe has been rearranged and rewelded
reducing the vibration value by a big margin
making operation of the feed-water pump to be normal.
