1. Reasons for the increase in bearing temperature

(1). The bearing cooling water stops.

(2). The oil quality is degraded, the oil itself is not clean or the oil is degraded during operation. If the moisture in the oil increases, the acidity of the oil floor will increase, which will reduce the smoothing effect of the oil floor, cause the bearing bush to be corroded, and cause the temperature of the bearing to rise.

2. Disposal of elevated bearing temperature

When the bearing temperature rises, first determine whether it is malfunctioning. If it does rise, similar treatments should be done:

(1). Check whether the cooling water pressure, water flow and pipeline system are deformed. If the water pressure is low, it may be a filter blockage. When it cannot be processed in time, it can be shut down for processing. When it is confirmed that it can work, it can be put into use.

(2). The oil pressure of the governor should be reviewed. If the oil pressure is low, the cooling water hydraulic valve may be closed.

(3). Check whether the bearing has abnormal noise, and check whether the bearing swing is abnormal.

(4). Take an oil sample to see if there is any change in the oil color, and perform a test to see if it has deteriorated. If the deterioration is confirmed, the machine should be shut down and replaced with new oil.

(5). Check whether the oil level of the oil level is normal. If it is abnormal, check whether the drain valve of the oil tank is closed tightly. If it has been closed tightly, oil should be refilled, similar to this, if the sealing rubber gasket is leaking oil, the machine should be shut down for treatment.

When we are using bearings, in the case of high temperature similar to the invention, we should stop the operation of the equipment as soon as possible, and then find out the reason, and make a treatment according to the solution plan provided above. However, the reason may be different due to the increase in bearing temperature.
