我站地处鄂西北山区,每到丰水期,水流挟带青苔等软质杂物经过拦污栅和过滤器,堵塞上导、下导、水导冷却器,造成导轴承温度升高。经检查,发现污物集结在冷却器进口处,该处与冷却进水管相接,是一个由粗变细的突变不光滑连接段,污物到此处,由于阻力增大,容易造成堵塞。为了排除堵塞,我们一开始以低压压缩空气从冷却器的出水口反向吹扫,这种方法虽然能解决问题,但存在两大缺点:一是冷却水管一般为丝扣连接,麻丝浸漆密封,拆卸冷却器出水管和进水管时容易使与冷却器直接相连接的止漏密封损坏,冷却器恢复通水时,水就容易渗入油盆,劣化油质,影 I was stationed in the mountainous area of ​​northwest Hubei Province. Every wet season, the flow of water entrained with moss and other soft debris through the trash rack and filter, block the upper guide, lower guide, water guide cooler, causing the guide bearing temperature to rise. After examination, it was found that the dirt was collected at the cooler inlet, which was connected with the cooling water inlet pipe. It was a non-smooth connecting section caused by the sudden change of the thick and thin, and the dirt was here. As the resistance increased, it was easy to cause blockage. In order to eliminate the blockage, we first low-pressure compressed air from the cooler outlet reverse purge, although this method can solve the problem, but there are two major drawbacks: First, the cooling water pipes are generally threaded connections, Seal, remove the cooler outlet pipe and inlet pipe is easy to make direct connection with the cooler seal leak damage, the cooler to restore water, the water will easily penetrate the oil pot, deteriorating oil, shadow
