Description

technical field [0001] The invention belongs to the technical field of compressor oil pumps, and relates to a carbon dioxide gas compressor screw oil pump capable of automatically removing excess gas. Background technique [0002] As a part of the carbon dioxide compressor, the oil pump converts low-pressure oil into high-pressure oil, which provides oil delivery power for the compressor and meets the lubrication and heat dissipation requirements of the compressor. [0003] The screw in the traditional compressor screw oil pump is a single transmission movement, and its work efficiency is low, and it will be difficult to discharge excess gas inhaled. Long-term work will cause the valve core to absorb too much medium, which will reduce the life of the safety valve and deteriorate the sealing performance. This affects the operation of the oil pump. In addition, the efficiency of the pump operation should be coordinated with the safety valve. SUMMARY OF THE INVENTION [000...
