摘要(Abstract):

通过调查,指出了大型水泵导轴承常见的故障形式,分析了故障发生的原因,提出了导轴承的选用原则和提高其可靠性和耐久性的途径和方法。提高金属油润滑轴承的密封性能和排漏水能力,非金属清水润滑轴承采用护管式结构,提高泵机组和进水流道设计、制造、施工和安装水平,减小导轴承荷载,可以提高大型水泵导轴承的可靠性和耐久性。
Common malfunction forms of large pump guide bearing were pointed out through investigation,whose causes were analyzed.The selection principles of the bearing were put forward and the methods were advanced that could improve reliability and durability of the bearing.The methods are improving seal and water leakage drainage of metal oil-lubricated bearing;protecting pipe configuration being used in non-metal clear water lubricated bearing;improving design,manufacture,construction and installation of pump unit and suction passage.
