大型水泵轴瓦摩擦失效原因分析与技术改造

Analysis of the Causes of Frictional Failure and Technical Transformation of Large Water Pump Shaft Tile

基于甘肃省景泰川电力提灌水资源利用中心调水输水工程中的某泵站发生水泵轴瓦和轴套之间摩擦失效的主要原因分析,提出提升二者材料硬度与耐磨性质的改造技术。在改造之后,整个机组运行十分平稳,且噪声与振动均有这减小的情况。

Based on the analysis of the main causes of frictional failure between pump shaft tile and shaft sleeve in a pumping station of water transfer and transmission project of Gansu Province Jingtai River Electricity Irrigation and Water Resources Utilization Center,the transformation technology to improve the hardness and wear resistance of both materials is proposed.After the renovation,the whole unit runs very smoothly and the noise and vibration are reduced.
