哈尔滨大电机研究所于新建成的3000 t 推力轴承试验台,在进行岩滩电站302.5 MW 发电机27.5 MN 钨金瓦推力轴承出厂试验的同时,研制了一台设计负荷27.5 MN 的塑料瓦,并进行了试验。塑料瓦的单瓦面积由钨金瓦的3220 cm~2减小到3000 cm~2,承载负荷由27.5 MN 提高到30 MN,单位压力由钨金的5.34 MPa 提高到6.25 MPa。当加载到27.5 MN时,电阻温度计的指示温度为36℃,表面热
At Harbin Institute of Technology, Harbin Institute of Technology, a newly built 3000 t thrust bearing test rig, a 27.5 MN Tungsten-Metal-Thrust thrust bearing test was carried out at the Yantan Hydropower Station 302.5 MW while a plastic tile with a designed load of 27.5 MN was developed. Conducted a test. The area of single tile of plastic tile is reduced from 3220 cm ~ 2 to 3000 cm ~ 2 of tungsten tile, the load carrying capacity is increased from 27.5 MN to 30 MN, and the unit pressure is increased from 5.34 MPa of tungsten gold to 6.25 MPa. When loaded to 27.5 MN, the resistance thermometer indicates a temperature of 36 ° C and the surface is hot
