Horizontal rotating two-stage enthalpy increasing compressor

Abstract

The invention discloses a horizontal rotating two-stage enthalpy increasing compressor. The compressor comprises a casing (1) as well as an upper flange (2), an upper gas cylinder (3), a separating plate (4), a lower gas cylinder (5), a lower flange (6) and a lower cover plate (7) which can be arranged in the casing (1) in the axial direction of the casing (1); the lower flange (6) comprises a medium pressure cavity (8) communicating with a gas inlet of the lower gas cylinder (5); through holes (9) for communicating the medium pressure cavity (8) with a compression cavity of the upper gas cylinder (3) are correspondingly formed in the separating plate (4), the lower gas cylinder (5), the lower flange (6) and the lower cover plate (7); and a gas replenishing and enthalpy increasing port (10) communicating with the medium pressure cavity (8) is further formed in the casing (1). With the compressor, the inside temperature of a pump body can be reduced, and the compression efficiency of the compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a horizontal two-stage enthalpy-increasing rotary compressor. Background technique [0002] The structure of the existing ordinary horizontal two-stage enthalpy-increasing rotary compressor is as follows: figure 1 As shown, when the compressor is working, the refrigerant is firstly compressed into a high-pressure and high-temperature refrigerant through a two-stage cylinder, and then discharged into the casing 1'. The high-temperature and high-pressure refrigerant passes through the channel 3 of the pump body in the casing 1'. 'Flow to the exhaust pipe 2' at the end of the shell 1', and then discharge high-temperature and high-pressure gaseous refrigerant from the exhaust pipe 2'. During the working process of the compressor, since the refrigerated oil of the horizontal compressor is stored at the bottom of the housing 1', the refrigerated oil cannot cover and cool the upper...

AI Technical Summary

Problems solved by technology

The high-temperature and high-pressure refrigerant needs to flow from the channel 3' on the upper part of the pump body to the exhaust pipe 2'. During the flow of the refrigerant, the high-temperature refrigerant performs uninterrupted heat exchange on the upper part of the pump body, which increases the internal temperature of the pump body, thus reducing compressor compression efficiency
