我厂共有五台(2、5、6、7、8号)苏制水力机组。由于其推力轴承在结构上存在着较多的缺点,它们相继在53至56年按装投入运行以来,陆续在轴承绝缘、止漏、结构强度、冷油器铜管腐蚀、推力头与镜板结合面产生汽蚀破坏引起轴线易变等方面暴露出不少问题,严重威胁运行的安全。经多年来的试验与处理实践,我们逐渐摸索到了一些有效的改进措施,使推力轴承的运行性能不断得到改善。因此消除了推力头甩油现象,出现了像六号机组运行十年轴线稳定;四号机组在持续运行了九年之久才进行轴瓦的刮花等事例。近几年来,我厂又在推力轴承的运行监护方面初步开展了一些工作,尚有待进一步充实和完善。一、推力轴承的改进 I plant a total of five (2,5,6,7,8) Soviet-made hydraulic unit. Due to its structure of the thrust bearing there are many shortcomings, which have been installed and put into operation 53 to 56 years in succession, one after another in the bearing insulation, leakage, structural strength, brass oil cooler, thrust head and the mirror plate There are many problems exposed due to the axis change due to cavitation damage on the joint surface, which seriously threatens the operation safety. After years of testing and handling practices, we gradually found some effective improvement measures, so that the performance of thrust bearings continue to be improved. Thus eliminating the thrust thrown oil phenomenon, appeared on the 6th unit running ten years axis stability; No. 4 unit in continuous operation for nine years before the bearing scratches and other examples. In recent years, our factory has carried out some initial work in the operation supervision of thrust bearings, yet to be further enriched and improved. First, the thrust bearing improvement
