Sliding vane lubricating structure, compressor and refrigeration equipment

Abstract

The invention provides a sliding vane lubricating structure, a compressor and refrigeration equipment. The sliding vane lubricating structure comprises an oil supply structure, the oil supply structure comprises an oil supply channel and an oil pump assembly, one end of the oil supply channel communicates with a bottom oil pool of the compressor, the other end of the oil supply channel communicates with a sliding vane groove, and the oil pump assembly is configured to be driven by exhaust of a pump body assembly of the compressor; and lubricating oil in the bottom oil pool is pumped into the sliding vane groove along the oil supply channel. According to the sliding vane lubricating structure, the oil supply channel for supplying oil to the sliding vane groove from the bottom oil pool is arranged in the compressor, the oil pump assembly is additionally arranged, the oil supply capacity of the oil supply channel is improved, and driving force is provided for the oil pump assembly by means of high-speed airflow exhausted by the pump body assembly; and an oil pumping mechanism pumps lubricating oil at the bottom of the compressor into the sliding vane groove formed in an air cylinder of a compression mechanism, lubricating oil supply to a sliding vane is achieved, it is guaranteed that the sliding vane is in a good lubricating state all the time, and the running stability and reliability of the compressor are improved.

Description

technical field [0001] The disclosure belongs to the technical field of compressors, and in particular relates to a sliding vane lubricating structure and a compressor. Background technique [0002] Rotary compressors, scroll compressors, etc. are widely used as air-conditioning compression mechanisms because of their simple structure, small size, excellent performance, high stability, and fewer reciprocating parts. However, there are many friction pairs inside the compressor. , for rotary compressors, such as sliding vanes and sliding vane grooves, rollers, upper and lower flange end covers, rollers and upper and lower flange end covers, crankshaft and rollers, upper and lower flange end covers, etc., many friction pairs are easily generated The friction and wear between the matching end faces and the gap leakage have become important factors affecting the performance and reliability of the compressor. [0003] The wear of the sliding vane and the sliding vane groove, the ...

AI Technical Summary

Problems solved by technology

When the oil level in the compressor casing is low and the oil storage capacity of the liquid separator is small, the above two lubrication methods cannot be reliably lubricated, resulting in dry friction of the sliding plate and its friction pairs, and the performance of the pump body is reduced. At the same time, there is a high reliability. sexual risk
