Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor volute with a water cooling structure. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. The volute of an air compressor is an important component of the air compressor. It is mainly used to cooperate with the impeller to compress the gas. It also has the function of supporting and conveying the gas.

[0003] In the prior art, existing air compressors generate a large amount of heat due to the friction of the impeller stirring the gas at high speed. The gas expands due to the heat, which increases the difficulty of compression and thus reduces the compression efficiency. However, the general air compressor volute does not have a water cooling function, resulting in poor heat dissipation performance of the air compressor volute, which reduces the working efficiency of the air compressor and thus affects the service life of the air compressor.

[0007] Preferably, one end of the volute body is fixedly connected with a connecting port, and one end of the connecting port is fixedly connected with the gas flow channel.

[0008] Preferably, a connecting plate is fixedly connected to one side of the volute body, and the volute body and the connecting plate are integrally formed by casting.

[0010] Preferably, a second mounting hole is provided on one side of the volute body, so that when the water cooling pipe is integrally formed with the volute body, the water cooling pipe can be embedded in the middle part of the volute body.
