Abstract

The invention relates to an exhaust bearing pedestal, a screw compressor and an air conditioning unit. An exhaust opening is formed in the exhaust bearing pedestal; an opening of the exhaust opening is designed as follows: under a condition that the exhaust bearing pedestal is covered in a shell, gas exhausted by the exhaust opening is provided with a component which does rotational flowing along the inner wall of the shell around the axial line of the shell. The exhaust opening is formed in the exhaust bearing pedestal disclosed by the invention, so that air can be guided to do rotational flow along the inner wall surface of the shell around the axial line of the shell; therefore, the flowing path of air in the shell is lengthened, and noise caused by air pulse is reduced.

Description

Technical field [0001] The invention relates to the field of compressors, in particular to an exhaust bearing seat, a screw compressor and an air conditioning unit. Background technique [0002] For semi-hermetic screw compressors, when the compressor does not have a built-in oil separator core, the exhaust bearing seat is surrounded by an oil separator barrel to reduce noise. At this time, the gas discharged from the compressor enters the oil separator barrel through the exhaust bearing seat, and then exits the compressor through the discharge port of the oil separator barrel. Since the compressor does not contain a built-in oil separator core, the discharge port of the oil separator barrel must be at the bottom so that the refrigerant oil carried in the exhaust can be smoothly discharged from the compressor. For screw compressors with a lower slide valve structure, the discharge port of the exhaust bearing seat is generally at the lower part of the exhaust bearing seat. In th...
