The invention discloses a multiple compressor system and an oil balancing method and a device thereof. The multiple compressor system comprises a first compressor, a second compressor, a first connection pipe, a second connection pipe, a detecting unit and a control unit, wherein the first compressor is provided with a first exhaust cavity which is provided with a first oil balancing hole, the second compressor is provided with a second exhaust cavity which is provided with a second oil balancing hole, a first magnetic valve is arranged in the first connection pipe, a second magnetic valve is arranged in the second connection pipe, the detecting unit is used for detecting whether the first compressor and the second compressor are short of oil, and the control unit is connected with the first magnetic valve and the second magnetic valve. When the first compressor is short of oil, the first magnetic valve is controlled to be opened; and when the second compressor is short of oil, the second magnetic valve is controlled to be opened. According to the multiple compressor system, the compressors in the multiple compressor system can be prevented from being damaged because of oil shortage.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a multi-compressor system and an oil equalization method and device thereof. Background technique [0002] In a multi-compressor parallel system, the compressors are often damaged due to lack of oil for a long time. Therefore, the effective oil equalization method among the compressors is the key technology to ensure the stability of the system. For low-pressure chamber compressors, oil equalization between compressors can be achieved by setting oil-air balance pipes. However, since the oil chamber of the high-pressure chamber compressor is at the high-pressure end, the oil balance pipe cannot be directly used for oil equalization, and the refrigeration oil must be equalized through a specific oil equalization technology. [0003] Aiming at the problem that the compressors in the multi-compressor system in the related art are often damaged due to lack of oil for a long time, no effect...
