Abstract

The present invention provides a pump body assembly and a compressor with it. The pump body assembly includes a crankshaft part, the crankshaft part includes a long shaft part, an annular groove is arranged on the long shaft part, and a second An oil guide groove, the first oil guide groove communicates with the annular groove to guide lubricating oil into the annular groove; the bearing part has a bearing hole, the first section of the long shaft part is located in the bearing hole, and the annular groove is arranged on the first section. During the operation of the pump body assembly, the lubricating oil enters the annular cavity formed by the annular groove and the hole wall of the bearing hole through the first oil guide groove, which increases the contact area between the lubricating oil and the hole wall of the bearing hole, effectively improving Lubrication effect of crankshaft and bearing hole. Due to the arrangement of the annular groove, the rigidity of the long shaft part of the crankshaft part is reduced, the self-adaptive ability of the improved long shaft part is enhanced, the wear of the long shaft part and the bearing part is reduced, the service life of the compressor is prolonged, and the Compressor reliability.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a pump body assembly and a compressor having the same. Background technique [0002] In the rotary compressor in the prior art, its crankshaft is lubricated by rotating and supplying oil through the spiral oil guide plate installed on the inner side of its lower part. The main and auxiliary bearings of the crankshaft are lubricated mainly through the oil guide grooves on the main and auxiliary bearings. When the air conditioner is installed with a high drop, it is difficult for the system to return oil, which may easily cause insufficient lubricating oil in the compressor. For compressors that operate for a long time under harsh working conditions such as heat pump water heater high temperature heating, air conditioner T3 working condition high temperature refrigeration, etc., the large amount of lubricating oil discharged by the compressor may easily lead to oil sh...
