同轴汽轮给水泵推力轴承磨损研究

Wear and Tear Research of Thrust Bearing in Steam-turbine-driven Feed water Pump Co-axially

通过用带机械补偿系统的推力轴承 ,非对称水泵口环形式、水泵叶轮和轴的配合形式等关键技术的研究 。

In the paper,it is introduced that the problem of wear an d tear of the thrust bearing in a feed water pump which is co axially driven by a steam tur bine has been solved through research on the key technologies such as the thrust bearing with mechanical compensation system,and the matching of non symmetrica l port ring,the impeller and the shaft of the pump.
