Self-lubricating bearing temperature reason, phenomenon and processing method

Self-lubricating bearing temperature reason, phenomenon and 2021 - processing method 01 - 28 self-lubricating bearings, with its unique performance and economical efficiency widely used at home and abroad. The copper substrate with high strength and high hardness of copper alloy, than ordinary copper set of hardness, strength increased more than twice. The copper surface borehole inlaid graphite as the main set of oily solid lubricant, lubrication area accounts for about 25%, to produce a solid layer - bearing runtime itself Liquid mixed lubrication membrane, reduce the effect of friction, greatly improved the performance copper set itself. Can be in heavy load, high temperature, impact load, reciprocating motion, the water, bad working conditions, such hard to come on to the normal work. And ordinary copper ring wear speed up by oil film failure can't even use. This product has a history of nearly ten years, has been widely used in the industries. As the understanding of the product range will be more and more big, will have a good benefit to society. Once in the use of self-lubricating bearing temperature rise will increase the mechanical wear and tear, resulting in reduced and the service life of the following to understand the causes of self-lubricating bearing temperature, phenomenon and processing method. 1. The cause of the self-lubricating bearing temperature: ( 1) Self-lubricating 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, self-lubricating bearing temperature. 2. Phenomenon: 1) Has the alarm bell rang. ( 2) Machine by hydraulic mechanical failure bright light plate, indicating instrument temperature rise in the temperature of self-lubricating bearings, signal relay action. ( 3) The thermometer plate ( Inflating the thermometer) Black stitches overlap or more yellow and yellow needle. ( 4) A self-lubricating bearing temperature fault signals. 3. When self-lubricating bearing temperature, first of all determine whether false action, such as really 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) Check whether self-lubricating bearings have different sounds, and detection of self-lubricating bearings degrees whether there are 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.
