立式水轮发电机上、下导轴封,一般均采用牛皮、羊毛毡封油。由于在长期运行中油封两边压差造成油从油封内引出甩在下导托盘、线棒、上导盒内。尤其是下导,因甩油下导处到处是油污,发电机下部线棒被透平油渗透,用手指一按都能冒油,线棒上沾染了灰尘、杂质、影响线棒绝缘,加速线棒绝缘的老化;且耗油严重,平均每台机每天3～5公斤。 Vertical hydro-generator, the next guide shaft seal, are generally used leather, wool felt seal oil. As in the long-term operation of the oil pressure on both sides caused by the oil led from the oil thrown in the lower guide tray, bar, on the guide box. Especially under the guide, due to rejection of the oil under the guide is oil, the generator under the bar by turbine oil penetration, with a finger press can take the oil, the bar contaminated with dust, impurities, affect the bar insulation, speed up Wire rod insulation aging; and fuel-efficient, with an average of 3 to 5 kg per machine per day.
