水轮发电机组在运行中，保持轴瓦温度在允许的范围以内，是电站安全运行的保证。一台机组在安装完成投入正常运行以后，轴瓦温度一般应无较大的变化。如果由于季节原因引起外界温度发生较大变化，轴瓦温度上升或下降几度，这是正常的。如在外界温度变化不大时，轴瓦温度上... Hydro-generator set in operation, to maintain the bearing temperature within the allowable range, is the guarantee of safe operation of power plants. A unit in the installation is completed and put into normal operation, the bearing temperature should generally no major changes. It is normal if there is a large change in the outside temperature due to the season and the pad temperature rises or falls by a few degrees. If little change in temperature in the outside world, the bearing temperature ...
