The invention discloses a gas pulsation attenuation device and an air compressor. The gas pulsation attenuation device is arranged in the air compressor, wherein a sealed space is formed in the air compressor. The gas pulsation attenuation device comprises a high-pressure exhaust end part, a clamping plate and at least one cover plate, wherein at least one gas pulsation attenuation cavity is formed among the high-pressure exhaust end part, the clamping plate and the at least one cover plate; at least one damping channel is formed in the cover plate; and the damping channel communicates the gaspulsation attenuation cavity with the sealed space. According to the gas pulsation attenuation device and the air compressor, gas pulsation in the sealed capacity of the compressor can be attenuatedby virtue of the friction action of the damping channel and the buffer action of the gas pulsation attenuation cavity.
Description
technical field [0001] The present disclosure relates to the technical field of airflow processing, in particular to an airflow pulsation attenuation device and an air compressor. Background technique [0002] As a general-purpose equipment for increasing gas pressure and transporting gas, compressors are widely used in industrial fields such as petroleum, natural gas, chemical industry, and metallurgy. Among them, the screw compressor is a rotary volumetric compressor. The motor drives the female and male rotors to mesh with each other to form the volume change of the working chamber, and realize the periodic suction, compression and exhaust working process of the screw compressor. [0003] Accompanied by the periodic fluctuation of gas pressure and flow during the suction and exhaust process of the screw compressor, air flow pulsation will occur. Among them, during the compression process, as the closed volume decreases, the pressure gradually increases, and the air flow ...
