弹性金属塑料瓦在大型水泵机组中的应用分析

Application Analysis of Elastic Metal-Plastic Thrust Bearing Pads in Large Pumping Unit

金属推力瓦烧损故障在水电站发生较多,在大型泵站也常有发生。弹性金属塑料推力瓦是近年来研制开发的一种新型轴瓦,有效解决了推力瓦烧瓦问题。介绍了江都第四抽水站采用弹性金属塑料推力瓦,成功解决了立式电机巴氏合金推力瓦烧损问题的应用情况,分析了其运行及安装、检修特性。为更好地完善和正确使用塑料推力瓦提供参考。

The Elastic metal-plastic thrust bearing pad is a new kind of bearing pad in recent years, which has been already extensively applied in water-turbine generator set. The fourth pumping station of Jiangdu has used the elastic metal-plastic thrust bearing pads, which is more earlier in large pumping station, the burnout of the vertical motor babbit alloy thrust bearing pads has been settled successfully. For more perfect and right using the elastic metal-plastic thrust bearing pads, its success application is introduced, its characteristics of running, installation and repair are analyzed.
