Star shaped compressing mechanism

Abstract

The invention relates to a star-shaped compressing mechanism. Four air cylinders are positioned on an identical plane inside a compressor casing body and present star-shaped distribution on the periphery of a working cavity, wherein, the inner diameters of the four air cylinders are gradually reduced from the first class to the fourth class; the main axle of the motor extends into the working cavity inside the compressor casing body, and a driving wheel is installed at the inner end of the main axle of the motor; an air inlet opening of the first-class air cylinder compressing cavity is communicated with an air inlet pipe, an air outlet opening of the first-class air cylinder compressing cavity is connected with an air inlet opening of the second-class air cylinder compressing cavity, an air outlet opening of the third-class air cylinder compressing cavity is connected with an air inlet opening of the fourth-class air cylinder compressing cavity, and an air outlet opening of the fourth-class air cylinder compressing cavity is connected with the air outlet pipe. The star-shaped compressing mechanism has the advantages that all of the air cylinders present star-shaped distribution on the identical plane, both the balance and the reliability during the operating process are good, the operation of the whole mechanism is stable, the vibration is small, the noise is low, and the efficiency of the compressed air transmitted to the next level through being compressed is high.

Description

technical field [0001] The invention relates to a compressor, in particular to a star compression mechanism of the compressor. Background technique [0002] As the power source of various pneumatic devices, air compressors have a wide range of applications. The compression mechanism of a traditional air compressor is generally composed of a compressor housing, a motor shaft, a crankshaft, a connecting rod, and a cylinder. The motor shaft is connected to the crankshaft in the compressor housing, and the cylinder is arranged next to the crankshaft. It is connected with the crankshaft through a connecting rod, and the cylinder is arranged in an "L" shape or a "V" shape or an "H" shape. The motor drives the crankshaft to rotate. When the crankshaft rotates, it drives the connecting rod to move, so that the piston makes a reciprocating linear motion in the cylinder. The reciprocating linear motion of the piston compresses the gas sucked into the cylinder step by step, and finall...

AI Technical Summary

Problems solved by technology

[0003] 1. The cylinders are not arranged in the same plane, the force balance and reliability are poor during operation, and large vibration and noise will be generated

[0004] 2. The efficiency of compressed air to be transmitted to the next stage through compression is low, and the heat load is high, which is easy to generate carbon deposits on the valve plate, and the service life of the valve plate is short

[0005] 3. The structure is complex, the manufacturing cost is high, and the replacement and maintenance of parts are difficult

[0006] 4. The space size is large and covers a large area
