How to deal with the high temperature of non-standard bearings?

The life of non-standard bearings is closely related to manufacturing, assembly and use. It must be done well in each link to make non-standard bearings in the best running state, so as to extend the service life of non-standard bearings.
1. How to deal with the influence of excessive temperature of non-standard bearings
(1) The alarm bell will ring.
(2). The light plate of the mechanical failure of the water wheel beside the machine is bright, the temperature of the instrument indicating the temperature of the non-standard bearing rises, and the signal relay operates.
(3). Thermometer tray (expansion thermometer) black needle and yellow needle coincide or exceed the yellow needle.
(4) Send out the fault signal of non-standard bearing temperature rise.
2. Causes of high temperature phenomenon of non-standard bearings
(1). It is possible that the cooling water of non-standard bearings is interrupted, resulting in high temperature phenomenon.
(2). It is possible that the oil quality of non-standard bearings is deteriorated, the oil itself is not clean or the oil is deteriorated in operation. Such as the increase of water in the oil will cause the acidity of the oil to increase, will reduce the lubrication of the oil, so that the bearing is corroded, and then cause the phenomenon of non-standard bearing temperature rise.
3. Treatment of non-standard bearings when high temperature phenomenon occurs
When the temperature of non-standard bearing rises, it is necessary to judge whether there is any wrong action first. If the temperature is indeed rising, the following treatment should be done immediately:
(1) Check whether the water pressure, water flow and piping system of cooling water are normal. If the water is low, the filter may be blocked, and can not be treated in time, it can be stopped for processing, and then put into use when it is confirmed that it can work.
(2). Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may be closed.
