一概述某站7~#水泵机组为单机800千瓦同步电电动机拖动的1.6米轴流泵。检修后盘车记录情况如表1: 机组投入正常运行12分钟就发现推力瓦温度急剧上升,达到71～74℃(这时上、下导瓦温度为50℃),从而被迫停机。开始误判为供、排水系统发生障碍,经检查无异常情况。再次启动机组,2分钟后推力瓦温度 An overview of a station 7 # pump unit for a single 800 kW synchronous motor drag 1.6 m axial pump. After the inspection, the records of the disc brake are shown in Table 1: The unit is put into normal operation and found that the temperature of the thrust pad rises sharply to reach 71-74 ° C (at this time, the upper and lower guide shoe temperature is 50 ° C) within 12 minutes, thus being forced to stop. Misjudged as the beginning, drainage system obstacles, after inspection no abnormalities. Start the unit again, thrust pad temperature after 2 minutes
