近年来,苏联古比雪夫航空学院研制出一种复合材料,可用作水轮发电机的推力瓦。苏联《水工建设》1977年第10期介绍了伏尔加列宁水电站和萨拉托夫列宁共青团水电站的水轮发电机用该复合材料做推力瓦的试验情况,1982年第6期又介招了布拉茨克水电站进行试验的情况。该复合材料由四氟化塑料和冲压蜗式金属丝作经线制成,简称ЭМП。用它作水轮发电机的推力瓦有如下优点:它和镜板的摩擦系数小,仅为0.09～0.10,而巴氏合金则为0.15～0.20,
In recent years, the Soviet Union Kuberchev Aviation Institute developed a composite material that can be used as a hydro-generator thrust pad. Soviet Union “hydraulic construction” in 1977 tenth introduced the Volguning Hydropower Station and the Saratov Lenin Hydropower Station hydroelectric power generator using the composite material to do the trial of thrust tile, in 1982 No. 6 also referred to the cloth Rakski hydropower station to test the situation. The composite material is made of tetrafluoride plastic and scrolling wire made of warp thread, referred to as ЭМП. Use it as a hydroelectric generator thrust tile has the following advantages: It and the mirror plate friction coefficient is small, only 0.09 to 0.10, while the Babbitt is 0.15 to 0.20,
