Abstract

The invention discloses a compressor and an oil-return switching method. The compressor comprises an oil return pipeline and an oil uniformizing pipeline. The inlet end of the oil uniformizing pipeline and the outlet end of the oil return pipeline are connected to a bottom oil pool of the compressor, the inlet end of the oil return pipeline is connected to an oil return port of an upper oil pool of the compressor, and a preset oil level is set in the bottom oil pool of the compressor. The compressor further comprises an oil way switching device connected with the oil uniformizing pipeline and the oil return pipeline, and the oil way switching device has an oil uniformizing state and an oil return state. The compressor is capable of quickly returning oil and quickly uniformizing oil, oil balancing time is greatly shortened, existing oil is fully utilized for being distributed between all compressors, the oiling amount is effectively reduced, and oil utilization cost is reduced.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor, and also relates to an oil return switching method, in particular to an oil return switching method for a compressor. Background technique [0002] With the rapid development of multi-unit units, the application range of large-capacity and capacity-adjustable air-conditioning units composed of multiple compressors is becoming wider and wider. Multi-connected units usually have the characteristics of long pipelines, large drops, and many elbows. Compared with the operation of a single compressor, it is easy for a certain compressor to suffer from oil shortage or oil accumulation in a multi-connected unit. In order to ensure multiple The lubricating oil in each compressor in the multi-connected system runs at a safe oil level. A core technical problem that needs to be solved in the multi-connected unit is to maintain a stable and reliable oil balance technology among multip...
