给水泵轴镀铬对振动测量的影响
摘要
华能福州电厂一期机组给水泵检修中对泵主轴采用了镀铬修复工艺
检修后给水泵试转时发生轴振异常波动现象。对此
在试验基础上对泵轴重新进行镀铬修复
镀铬修复后
泵轴振动测量指示正常。
Abstract
During repair period of feed-water pumps for units in the first-phase project of Huaneng Fuzhou Power Plant
the chronium-plating repair technology had been adopted for the main shafts of said pumps.After repair
abnormal fluctuation phenomenon of shaft vibration has occurred in trial operation of the feed-water pumps.For this
the shaft of pumps has been chronium-plated again on the basis of test.After chronium-plating
the indication of vibration measurement for pumps' shaft is normal.
