When some SKF bearings are in the process of using some errors, it will incur high temperature appearance. So it is not to comment on how much temperature is a good problem; but to pay attention to and prevent the problem of high temperature of SKF bearings. Prevent SKF Bearings caused by high temperature; even the formation of bearing damage can not be used.
Let's comment on the reason why SKF bearings exhibit excessive temperature.
1. The reason for the high temperature appearance of SKF bearing:
(1). There is a cooling water that can be SKF bearings; form a high temperature surface.
(2). There is oil quality deterioration that can be SKF bearings; the oil itself is not clean or the oil is degraded during operation. If the water is added in the oil, the acidity of the oil will increase; the smoothing effect of the oil will be reduced; the bearing bush will be corroded; and then the SKF bearing will be formed. The appearance of elevated temperature.
2. What are the appearances when the SKF bearing temperature is too high?
(1). The alarm bell will ring.
(2). The machine side water wheel mechanical fault light plate is bright; the external temperature indicating the bearing temperature rises; signal relay measures.
(3). Thermometer disk (bulging large thermometer) black needle and yellow needle coincide or exceed the yellow needle.
(4). Announce the fault signal of the bearing temperature rise.
3. SKF bearings are treated in the presence of high temperature images.
When the temperature of the SKF bearing rises; firstly, it is necessary to determine whether there is a wrong measure; if the temperature is indeed rising; the following treatment should be done immediately:
(1). Check the water pressure of the cooling water; whether the water flow and the pipeline system can be normal. If the water pressure is low, it can be blocked by the filter; if it can not be disposed of in time; it can be stopped; when it is admitted that it can work;
(2). Should check the oil pressure of the governor; if the oil pressure is low, the cooling water hydraulic valve can be closed.
(3). Check if the bearing can have abnormal sound; and check whether the bearing swing can be abnormal.
(4). Take oil samples to investigate whether the oil color can be changed; and carry out tests to see if it can change. If you admit to deterioration, you should stop replacing new oil.
(5). Check if the oil level oil level is normal; if it is abnormal; check if the oil drain valve can be closed. If it is closed, it should be replenished; if it is leaking oil, it should be stopped.
Total return; to prevent the appearance of high temperature representation of SKF bearings; add its service life.
