In the past, we contact common examples, summarized and analyzed the following reasons:

1.1. Bearing cooling water is interrupted.

1.2. Mechanical failure of the water wheel on the side panel of the machine lights up, the temperature of the instrument indicating bearing temperature rises, and the signal relay moves.

1.3 Thermometer plate (expansion thermometer) black needle and yellow needle overlap or exceed the yellow needle.

1.4, oil deterioration, oil itself is not clean or oil deterioration in operation, such as the increase in water in the oil will cause the acidity of the oil to increase, will reduce the lubrication effect of the oil, make the bearing bush corrosion, causing the bearing temperature rise.

When we learn what causes the bearing temperature to rise, the second step should be to find a solution. The above four points will lead to the temperature rise of the bearing. According to examples over the years, the following points are the treatment methods, and I hope to help you solve the problem.

2.1. Check whether the water pressure, water flow and pipeline system of cooling water are normal. If the water pressure may be the filter blockage, can not be treated in time, can be shut down processing, when confirmed to work, and then put into use.

2.2. Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may be closed.

3.3, take oil sample to observe whether there is a change in oil color, and test to see whether metamorphism. If confirmed deterioration, should stop the replacement of new oil.
