Problems solved by technology

When the scroll compressor is working, especially when it is running at low speed, the refrigerant circulation volume is reduced, and the oil content in the suction gas is reduced, resulting in insufficient oil supply to the compression chamber and the Oldham ring of the scroll compressor.

Abstract

The invention discloses a scroll compressor with an active oil supply system, and relates to the technical field of scroll compressors for air conditioners, in particular to a horizontal scroll compressor with the active oil supply system. A movable scroll cross-shaped ring cavity oil supply structure is arranged between a cross-shaped ring cavity and a crankshaft oil way; a movable scroll compression cavity oil supply structure is arranged between the cross-shaped ring cavity and a compression cavity; lubricating oil in an oil pool is pumped into a crankshaft oil way by a positive displacement pump through an oil suction pipe assembly and enters the cross-shaped ring cavity through the movable scroll cross-shaped ring cavity oil supply structure, after the lubricating oil in the cross-shaped ring cavity reaches a certain height, the lubricating oil enters the compression cavity through the movable scroll compression cavity oil supply structure for lubrication, the lubricating oil is discharged out of a scroll cavity along with a refrigerant, and the oil returns to the oil pool. According to the technical scheme, the problem that in the prior art, the lubricating oil on all sliding faces of the compression cavity and a cross-shaped ring of the horizontal scroll compressor is not uniform is solved.

Description

technical field [0001] The invention relates to a scroll compressor with an active oil supply system, and relates to the technical field of scroll compressors for air conditioners, in particular to a horizontal scroll compressor with an active oil supply system. Background technique [0002] Scroll compressors have become the mainstream compressors used in the refrigeration field due to their compact structure, low noise, and high energy efficiency. However, there are many mechanical friction pairs inside. If the machining accuracy of the sliding surface of the friction pair does not meet the requirements, the structural design is unreasonable, and the lubrication is insufficient, it will cause energy loss, increase in input power, and decrease in energy efficiency. The relative movement between the rotary discs is unstable, which directly leads to damage to the compressor, reducing its reliability and service life. With the rapid development of high-precision machining tec...
