As one of the core components of mechanical equipment, fluid coupling can improve the efficiency of equipment by 30%, but its failure will directly affect the operation of equipment and even cause the production line to stop. Hydraulic couplings are widely used in coal mining and other fields. Bearing damage is a common fault, and temperature rise is an important inducement. The following are ways to avoid this problem:
I. Identify the reasons for bearing damage caused by temperature rise. Impurity accumulation and long-term operation: Hydraulic couplings need to run for a long time due to production needs. The internal liquid has been used for a long time, and impurities are constantly accumulated. When the bearing is running at high speed and in a relatively closed environment, it is difficult for the heat to dissipate, resulting in severe temperature rise, and eventually bearing failure, and even coupling failure. Poor lubrication causes high temperature: Poor bearing lubrication will cause abnormal friction and wear, generate a lot of heat, affect the material organization and lubricant performance, and gradually make the lubricant ineffective. Due to the high operating speed of the coupling, the bearing temperature will rise rapidly, which will cause bearing damage and coupling strike.
II. Preventive measures to avoid bearing damage caused by temperature rise Select high-quality grease and standardize maintenance: Select high-quality grease to maintain the bearing and check it regularly. For equipment that runs for a long time, the relevant parts should be disassembled and maintained when it is shut down to prevent the grease from failing due to high temperature.
Regular inspection and replacement of lubricants: Based on the operating frequency of the coupling, the lubricant is regularly inspected to ensure that there are no impurities such as metal objects. Grease should be regularly replenished or replaced in accordance with regulations, and the amount of grease should be moderate. The bearing box should be refueled regularly in strict accordance with the requirements to ensure that the bearing is always in a good lubrication state and reduce friction heat.
Regular disassembly, inspection and cleaning: For hydrodynamic fluid couplings that run for a long time, they should be shut down and disassembled regularly to clean up the impurities accumulated inside, check the wear of the bearings, and promptly discover and deal with potential problems to avoid impurities affecting the heat dissipation and normal operation of the bearings.
Through the above measures, the probability of turbo fluid coupling temperature increase can be effectively reduced, the risk of bearing damage can be reduced, and the stable operation of the equipment can be guaranteed.
