Technical Field

The utility model relates to the technical field of sliding bearings, in particular to a sliding bearing for a large compressor.

Background

The compressor is a driven fluid machine that lifts low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. The low-temperature low-pressure refrigerant gas is sucked from the air suction pipe, the piston is driven to compress by the operation of the motor, and then the high-temperature high-pressure refrigerant gas is discharged to the air discharge pipe to provide power for the refrigeration cycle, so that the refrigeration cycle of compression, condensation (heat release), expansion, evaporation (heat absorption) and the bearing working under sliding friction are realized. The sliding bearing works stably and reliably without noise. Under the condition of liquid lubrication, the sliding surfaces are separated by the lubricating oil without direct contact, friction loss and surface abrasion can be greatly reduced, and the oil film has certain shock absorption capability.
