摘　　要：为了全面分析现有的锡基合金瓦和改性四氟乙烯塑料瓦的性能情况,对水轮发电机组常用的锡基合金ZSnSb11Cu6推力轴瓦和改性聚四氟乙烯推力轴瓦进行性能实验分析,通过对比锡基合金ZSnSb11Cu6和改性聚四氟乙烯的耐温性能、硬度、摩擦磨损性能,分析出推力轴瓦的最优耐温值、硬度值和摩擦磨损情况。进一步验证改性聚四氟乙烯推力轴瓦材质性能优越性,为不同种类、大小的传统锡基合金瓦电站提供有价值的技改性能参考数据。In order to fully analyze the performance of the existing tin-based alloy tiles and modified PTFE plastic tiles,this paper analyzes the performance of the commonly used tin-based alloy ZSnSb11Cu6 thrust bearings and modified PTFE thrust bearings for hydro-generator sets.By comparing the temperature resistance,hardness,friction and wear properties of the tin-based alloy ZSnSb11Cu6 and modified PTFE,the optimal temperature resistance,hardness and friction and wear conditions of the thrust bearing are analyzed.It further verifies the superiority of the material performance of the modified PTFE thrust bearing bush,and provides valuable technical modification performance reference data for different types and sizes of traditional tin-based alloy tile power stations.
