Compressor lubricated in refrigerant immersion mode

Abstract

The invention discloses a compressor. The compressor comprises a rotor, a bearing and a liquid storage tank, wherein the bearing sleeves the rotor; and the liquid storage tank can accommodate a refrigerant and lubricate the bearing through the refrigerant with a lubricating effect. According to the embodiment of the compressor, the liquid storage tank carries the refrigerant with the lubricating effect, the refrigerant is enabled to lubricate the bearing, and at the same time, a lubrication system in the compressor is simplified by using the heat conduction and lubricating effects of the refrigerant.

Description

technical field [0001] The invention relates to the field of refrigeration and air conditioning, in particular to a compressor immersed and lubricated by a refrigerant. Background technique [0002] For general rotating machinery, the lubrication of the rotating parts will play a decisive role in the normal operation of the rotating machinery. And because the bearing is a key part in the rotating parts, in order to ensure its good lubrication, it needs to continuously provide lubricating fluid for lubrication. Existing rotating machines often use independently provided lubrication systems to lubricate different components, and the lubrication systems at least include components such as a liquid storage tank, a communication pipeline, a pressure pump, and a nozzle. [0003] The lubricating fluid for the bearings of related rotating machinery is mostly sprayed by nozzles. In order to ensure the lubrication effect, the lubricating fluid entering the nozzle needs to have a cert...

AI Technical Summary

Problems solved by technology

figure 1 The lubricating system shown is complex in structure, and the lubricating performance of the bearing is affected by the comprehensiveness and uniformity of the nozzle spray liquid. The lubricating effect is difficult to guarantee, and the cooling effect of the lubricating liquid on the bearing is limited, so it is difficult to achieve good lubrication and heat dissipation of the bearing.
