The cause of the bearing temperature, phenomenon and handling - bearing knowledge

The analysis of the rolling bearing temperature 1. Reason: ( 1) 。 Rolling bearing cooling water. ( 2) 。 Degradation of oil, the oil itself is not clean or run medium oil degradation, such as moisture in the oil increase can cause the acidity of the oil, can reduce oil lubrication, the bearing shell was corrosion, cause temperature rise of rolling bearing. 2. Phenomenon: ( 1) 。 ( 2) 。 Machine by hydraulic mechanical failure bright light plate, indicating instrument temperature rise in the temperature of rolling bearings, signal relay action. ( 3) 。 The thermometer plate ( Inflating the thermometer) Black stitches overlap or more yellow and yellow needle. ( 4) 。 A rolling bearing fault signal of temperature. 3. Processing when the rolling bearing temperature, first determines whether the misoperation, as did rise, should do the following treatment: ( 1) 。 Check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. ( 2) 。 Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. ( 3) 。 To check whether there is sound, rolling bearing and detect rolling bearing place whether there is abnormal. ( 4) 。 Take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. ( 5) 。 Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing.
