Problems solved by technology

[0002] The first-stage, second-stage and third-stage compression components in the three-stage compressor in the related art are all rotary compression structures. The characteristic of the exhaust of the rotary compression structure is that the exhaust is only carried out within the range of 180° of roller rotation. Gas, the exhaust is intermittent, which seriously affects the efficiency of the three-stage compressor
Although in the prior art, the problem of intermittent exhaust is alleviated by setting an intermediate cavity (medium pressure cavity), the suction channel of such a structure is too long, and the refrigerant gas is easily heated by the high-temperature environment inside the pump body, which affects the cooling / production process. poor thermal performance

Abstract

The invention discloses a three-stage compressor and refrigeration equipment with the same. The three-stage compressor comprises a shell, a compression mechanism, a first partition plate, a second partition plate and a bent shaft. The compression mechanism comprises a first-stage compression component, a second-stage compression component and a third-stage compression component. The first-stage compression component, the second-stage compression component and the third-stage compression component include at least one rotating compression component and at least one centrifugal compression component. The first partition plate is arranged between the first-stage compression component and the second-stage compression component. The second partition plate is arranged between the second-stage compression component and the third-stage compression component. The bent shaft comprises a body portion and at least one offset shaft portion formed on the body portion. The offset shaft portion is sleeved with a roller. The body portion is sleeved with an impeller. The three-stage compressor is high in efficiency and good in performance.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a three-stage compressor and refrigeration equipment with the three-stage compressor. Background technique [0002] The first-stage, second-stage and third-stage compression components in the three-stage compressor in the related art are all rotary compression structures. The characteristic of the exhaust of the rotary compression structure is that the exhaust is only carried out within the range of 180° of roller rotation. Gas, the exhaust is intermittent, which seriously affects the efficiency of the three-stage compressor. Although in the prior art, the problem of intermittent exhaust is alleviated by setting an intermediate cavity (medium pressure cavity), the suction channel of such a structure is too long, and the refrigerant gas is easily heated by the high-temperature environment inside the pump body, which affects the cooling / production process. Poor thermal performance. Co...
