Abstract

The invention discloses a compressor fan and a compressor. The compressor fan comprises a substrate and a plurality of blades, wherein the blades are connected with the substrate and are arranged along a radial direction of the substrate; each blade is provided with a through hole penetrated along a width direction of the blade. Through the arrangement, a gas channel is formed between two blades;each blade is provided with the through hole, so that two adjacent gas channels communicate with each other; meanwhile, non-channel area located at the outer sided of the blades at the edge communicate with the gas channels, so that the gas is leaked when the fan operates, the gas pressure is reduced, the gas injection speed is reduced, and the pneumatic injection noise is reduced; and the problemof high pneumatic noise generated by the fan in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of compressors, more specifically, to a compressor fan and a compressor. Background technique [0002] For the existing horizontal compressors, in order to ensure the oil supply of the shafting, such as figure 1 As shown, a part called fan 3 is often fixedly installed on the rotor 2 of the crankshaft 1 long axis section. Such as figure 2 As shown, the fan 3 is usually provided with three radially arranged blades, and a gas channel is formed between two adjacent blades. When the fan 3 rotates with the rotor 2 at high speed, the blade draws air from the inside to the outside through two gas passages to reduce the gas pressure in the center of the rotor 2, thus ensuring the oil supply to the shafting of the horizontal compressor. However, the existing fan 3 is in the high-pressure refrigerant gas. When the fan 3 rotates at a high speed, its blades will inevitably stir the high-pressure refrigerant. ...
