Preventive maintenance of compressor equipment

Preventive maintenance of compressor equipment

Compressor as a mechanical equipment, after a period of operation, due to wear, deformation, corrosion, blockage and other reasons to produce failures or failure precursors, so it is normal and necessary to repair. However, there are many types of compressor repairs. According to the order of maintenance time, it can be divided into two categories: after-event maintenance and preventive maintenance.

　　 The so-called post-maintenance is to repair the compressor equipment after failure or low performance is called post-maintenance. In the early 20th century, mechanical equipment maintenance was generally carried out after the failure, that is, after-the-fact maintenance. Its z* big advantage is that it makes full use of the life of parts or system components, but afterwards maintenance is unplanned maintenance, which wastes more remaining repairs, and there are also certain defects and deficiencies.

　　 Preventive maintenance refers to the maintenance method that confirms the status of the equipment in advance based on the operation cycle and frequency of use of the equipment.

　　If you ask everyone, is it better to repair after the event or preventive repair? Probably most people think preventive maintenance is good. Then, compared with after-the-fact maintenance, few people seem to think seriously about the advantages of preventive maintenance.

There are two specific modes of preventive maintenance. One is regular preventive maintenance, which is the shutdown and maintenance scheduled according to the compressor equipment wear cycle plan; the second is condition maintenance, which is to monitor the status of the equipment, find hidden troubles or potential failures, and arrange timely maintenance in time , To eliminate the fault in the budding state.

　　 Another form of preventive maintenance is opportunistic maintenance. That is, preventive maintenance is carried out during the off-season, holidays, weekends, or upstream and downstream downtime for maintenance. The "opportunity" for opportunistic maintenance can be to appropriately extend the maintenance period or to appropriately shorten the maintenance period. After demonstration, this extension or shortening will not cause major damage to the equipment. Such preventive maintenance is also called opportunistic maintenance. No matter what preventive maintenance method is adopted, it is the treatment before equipment failure and shutdown, the purpose is to avoid the occurrence of failure....
