Centrifugal variable-capacity type compressed gas compressor and method

Abstract

The invention discloses a centrifugal variable-capacity type compressed gas compressor. The centrifugal variable-capacity type compressed gas compressor comprises a machine shell and a compressed disk. The centrifugal variable-capacity type compressed gas compressor is characterized in that a cavity of the machine shell is in a barrel-shaped structure; shaft holes are formed in the middle positions of two ends of the machine shell, a vent hole is formed in the side body of the machine shell; opposite buckle type disk-shaped disk covers are arranged on two sides of the compressed disk, embankment-shaped blades are arranged between the two disk covers, a hollow shaft and a power shaft are correspondingly arranged on the two sides of the two disk covers; and the disk compressed disk is installed in the machine shell; and the power shaft is connected with a power source. The compressor has a high rotational speed, large flow, no pulse, simple structure, precious few part used, low cost anda long service life, and is capable of continuous air exhaust, is not prone losing, at the same time the compressor has the advantages that the noise is low, the compressor is very smooth, and the mechanical wear is very low.

Description

technical field [0001] The invention relates to the field of air compression, in particular to a centrifugal variable capacity compressed gas compressor and a method thereof. Background technique [0002] Air compressor is a kind of equipment used to compress gas. Traditional air compressors are mainly speed type and volume type. Each type has its own shortcomings, and there are many problems: for scroll air compressors, the main The structure is complex and there are many parts; the parts that produce relative motion have many frictional contact surfaces, the sealing is difficult, the mechanical wear is large, and there is internal leakage; in addition, the requirements for raw materials and processing accuracy are high, so the cost is also high. Due to the scroll compression The structure of the machine, the axial force of the gas is very large, which is easy to cause a large power loss and parts wear and increase the energy consumption; for the centrifugal air compressor,...

Problems solved by technology

[0002] Air compressor is a kind of equipment used to compress gas. Traditional air compressors are mainly speed type and volume type. Each type has its own shortcomings, and there are many problems: for scroll air compressors, the main The structure is complex and there are many parts; the parts that produce relative motion have many frictional contact surfaces, the sealing is difficult, the mechanical wear is large, and there is internal leakage; in addition, the requirements for raw materials and processing accuracy are high, so the cost is also high. Due to the scroll compression The structure of the machine, the axial force of the gas is very large, which is easy to cause a large power loss and parts wear and increase the energy consumption; for the centrifugal air compressor, the structure is relatively complicated, the parts are many, the cost is high, and the compression The efficiency is low, the energy consumption is high, the high pressure and low pressure areas cannot be completely separated, and the internal leakage is large. In the field of air compressors, the innovative technology has not been greatly improved, and it is all on the traditional compressor. optimization, so its performance improvement is also limited
