3月1日,随着最后一台机组推力瓦的顺利更换,丹江电厂6台15万千瓦水轮发电机组已全部更换采用了原苏制弹性金属聚氟乙烯塑料推力轴瓦(简称氟塑瓦,这在全国还是第一家)。推力轴承是水轮发电机组最关键,也是最危险的部件。丹江电厂1号机组就曾发生过推力瓦烧损被迫停机达20天之久的大事故。每年夏季也因机组负何重,气温和水温高,使推力瓦工作于“过热停机”的危险边缘,机组还经常因推力瓦温过高而被迫限荷运行。特别是原 March 1, with the smooth replacement of the last unit of thrust shingles, Danjiang Power Plant 6 sets of 150,000 kilowatts hydro-generating sets have been replaced with the original Soviet-made flexible metal polyvinyl fluoride plastic thrust bushings (referred to as Fula tile , This is the first in the country). Thrust bearings are the most critical hydro generator units, but also the most dangerous parts. Danjiang Power Plant Unit 1 had occurred on the thrust tile burning was forced to shut down for 20 days of major accidents. Due to the heavy load and high temperature and water temperature, the thrust tile works on the dangerous edge of “overheat shutdown” every summer. The unit is often forced to run under limited load due to the high temperature of the thrust tile. Especially the original
