TIMKEN bearings need to pay attention to when applying force; the force of the force can pass through the axis of the bearing; this requires the force point to be evenly symmetrical and stable; Smooth and even; it is not suitable for impact; this requires the use of oil pressure or something that can apply a smooth tension or pressure; the real has to use hammering; also through the copper sleeve and other soft and not chipping metal to cushion; Do your best to be gentle. Use the copper rod or copper hammer for hammering. Prevent the force from being applied through the roll; this requires the inner ring to apply force when the inner ring (shaft ring) is removed; when the outer ring is assembled or removed) Apply force through the outer ring.
First, let's first look at the reason for the temperature rise of TIMKEN bearings:
(1). It can be the oil quality deterioration of TIMKEN bearing; 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 will increase; the smoothing effect of the oil will be reduced; the bearing bush will be corroded; the bearing temperature will rise. .
(2). Can be formed because of the cooling water of the TIMKEN bearing.
3. The appearance of TIMKEN bearing temperature rise:
(1). Announce the fault signal of the bearing temperature rise.
(2). Thermometer disk (bulging large thermometer) black needle and yellow needle coincide or exceed the yellow needle.
(3). The machine side water wheel mechanical fault light plate is bright; the external temperature indicating the bearing temperature rises; signal relay measures.
(4). There is an alarm bell ringing.
What to do if TIMKEN bearing temperature rises:
When the TIMKEN bearing temperature rises; the first discriminant can be mishandled; if it does rise; the following should be done:
(1). 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.
(2). 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.
(3). Check if the bearing can have abnormal sound; and check whether the bearing swing can be abnormal.
(4). Should check the oil pressure of the governor; if the oil pressure is low, the cooling water hydraulic valve can be closed.
(5). 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;
