本文针对我国水轮机存在的一些影响机组安全运行的共同问题,着重从设计、制造的角度,对水轮机汽蚀,剪断销在正常运行中频繁剪断,尼龙轴套抱轴,轴承甩油、结露与轴承运行温度过高,水导密封漏水,轴流式水轮机叶片密封漏油、进水以及转轮泄水锥运行中脱落等问题作了论证分析,并探索了相应的改进措施。对某些问题在分析的基础上,并作了调查或验证试验。证明文中提出的分析与改进措施是正准的,可供设计工作者参考。 In this paper, some common problems that affect the safe operation of turbines in our country are put forward. The design and manufacture of the turbines are mainly focused on the common faults of cavitation and shear pins in the normal operation of the turbines. Bearing operating temperature is too high, water leakage seal seal, axial flow turbine blade seal leakage, water and runner spout conical running off issues such as the demonstration analysis and exploration of the corresponding improvements. On some issues based on the analysis, and made a survey or verification test. Proof of the proposed analysis and improvement measures are accurate, for design workers for reference.
