船舶机械的可靠性,在很大程度上取决于机械主要构件的良好性能。为了保持这种性能,往往需要局部或全部拆卸这些主要构件予以检修或更换。对冷凝泵来说,轴的断裂、轴套的损毁和轴承的破坏均属于最严重的故障。《华沙》号油船装有两台72/85型冷凝泵,从1961年到现在一直在自调工况下运行,运转经验证明,除了首级和第二级叶轮存在不可避免的轻度的汽蚀破坏现象外,还发生了推力球轴承损坏的情况。由于存在着这样一种看法,即冷凝泵在自调工况下运行时轴向负荷远比其按冷凝器水位
The reliability of marine machinery depends to a large extent on the good properties of the main mechanical components. In order to maintain this performance, it is often necessary to dismantle or replace these main components in whole or in part. For the condensate pump, shaft rupture, sleeve damage and bearing damage belong to the most serious fault. The “Warsaw” oil tanker was fitted with two Model 72/85 condensing pumps, which operated from 1961 to the present in self-regulating conditions. Operational experience has shown that except for the first and second stage impellers there are inevitable mild steam Erosion damage phenomenon, but also occurred Thrust ball bearings damaged situation. Because of the existence of such a view that the condensate pump in the self-adjusting operating conditions when the axial load than its condenser water level
