摘要
对轴流泵立式电机上导轴承温度过高现象产生的内部原因和外部原因进行了较为全面的分析,并从减少径向载荷,改善润滑条件,提高热交换效率着手采取改进措施,有效降低了机组运行时上导轴承温升过高的现象,提高了机组运行的安全性,可以在很多类似场合推广。
The internal and external causation of superheating of radial bearing of large vertical pump unit electric motors were analyzed. On the basis of the analyses, three counter-measure of superheating were introduced. The results indicate that by means of lightening the radial load, improving the condition of lubrication, improving the efficiency of heat-exchange were available. These countermeasures can be generalized in many occasions.
