自动保持水轮发电机组轴承的正常润滑,是机组自动化的一个重要内容,也是保证机组安全运行的必要条件。我地区一水电站,4台1600kW 卧轴水轮发电机组,其润滑方式为压力油润滑。压力油系统设置有两台油泵,一台是与水轮发电机组同轴的机械油泵,另一台是电动油泵,两管路之间各加一逆止阀隔离。按原设计,机组在额定转速或接近额 Automatically maintaining the normal lubrication of hydro-generator set bearing is an important part of the unit automation and a necessary condition for ensuring the safe operation of the generator set. A hydropower station in my area, 4 sets of 1600kW horizontal axis hydro-generating units, the lubrication method is pressure oil lubrication. The pressure oil system is equipped with two oil pumps, one is a mechanical oil pump coaxially with the hydroelectric generating set, and the other is an electric oil pump with a check valve isolated between the two lines. According to the original design, the unit at rated speed or close to the amount
