1. The cause of the bearing temperature: (1). Bearing cooling water. (2). The degradation of oil, the oil itself is not clean or run medium oil degradation, such as moisture in the oil increase can cause the acidity of the oil, can reduce oil lubrication, the bearing shell was corrosion, cause temperature rise of bearing.

2. The phenomenon: (1). Have the alarm bell rang. (2). The machine by hydraulic mechanical failure bright light plate, indicates the instrument temperature, bearing temperature signal relay action. Disk (expansion (3). The thermometer thermometer) black stitches overlap or more yellow and yellow needle. (4). A bearing fault signal of temperature rise.

3. Processing: When the bearing temperature, first of all determine whether false action, such as really rise, should do the following: (1). Check the cooling water pressure, water flow and pipeline system is normal.If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. (2). Check the governor oil pressure, if the low oil pressure may lead to water hydraulic valve closed. (3). Check the bearing whether there is a different tone, and detect bearing place whether there is abnormal. (4). Is sample observation oil color have change, and tests to see if metamorphism.If confirm the degradation new oil should be replaced downtime. (5). Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut.If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing.
