Technical Field

[0001] The utility model relates to the technical field of rotor compressors, in particular to a pump body structure with double suction and exhaust functions and a rotor compressor. Background Art

[0002] In recent years, the technology of rotary compressors has developed rapidly and has been widely used in various refrigeration equipment. Existing rotary compressors are generally single suction and exhaust structures, that is, the piston moves in the cylinder once to complete one suction and exhaust action. R&D personnel have continuously sought to improve the efficiency of rotary compressors during the design and development process, and have achieved certain results in many aspects; however, there is still room for improvement in rotary compressors. Summary of the invention

[0003] The purpose of the utility model is to further improve the efficiency of the rotary compressor and to provide a pump body structure and a rotary compressor with double suction and exhaust.

[0004] The specific scheme of the utility model is: a pump body structure with double suction and exhaust, including a cylinder seat and an upper cylinder cover, the upper cylinder cover is connected and fixed to the cylinder seat, a cylinder is provided at the center of the cylinder seat, an air inlet A and an air inlet B are provided on the side wall of the cylinder seat, a sliding vane groove A is provided on one side of the air inlet A, and a sliding vane groove B is provided on one side of the air inlet B; the upper cylinder cover is provided with an exhaust port A and an exhaust port B, the exhaust port A is arranged on the other side of the sliding vane groove A relative to the air inlet A, and the exhaust port B is arranged on the other side of the sliding vane groove B relative to the air inlet B.

[0005] Furthermore, an exhaust valve plate mounting groove A and an exhaust valve plate mounting groove B are provided on one side of the upper cylinder cover. The exhaust valve plate mounting groove A is communicated with the exhaust port A, and the exhaust valve plate mounting groove B is communicated with the exhaust port B.

[0006] Furthermore, the exhaust valve plate mounting groove A is connected to one end of the exhaust valve plate mounting groove B, and a rivet hole is provided at the connection point, the rivet hole is used to install a rivet, and the rivet is used to fix the exhaust valve plate.

[0007] Furthermore, the inner wall of the cylinder of the cylinder seat is provided with notches corresponding to the exhaust port A and the exhaust port B.

[0008] The utility model also provides a rotor compressor equipped with the pump body structure.

[0009] Compared with the prior art, the utility model has the following advantages: by adding a group of suction holes and exhaust holes, the original compressor mechanism part is changed from a single-suction single-row structure to a double-suction double-row structure, which greatly improves the suction and exhaust efficiency of the compressor mechanism part, thereby improving the efficiency of the compressor.
