Rotary compressor

Abstract

A vane rotary compressor is composed of a rotor, a casing and a drive shaft. The cavity formed by the components between the rotor and the casing is divided into a cylinder and a lubricating cylinder. There are 4 leaves installed on the rotor to make a gradual hinge rotation in the casing and follow the revolution of the rotor. Two adjacent bosses of the rotor are covered by adjacent The two lobes and the casing are divided into a cylinder, that is, the compression cylinder. The two adjacent lobes and the casing on the same boss are divided into a lubrication cylinder. The cylinder volume is variable, and the volumes of other cylinders and lubricating cylinders are simultaneously variable. The volume changes between each other to realize the suction, compression and exhaust process. The strokes of the opposite two cylinders and the lubricating cylinder are opposite, and each stroke is carried out simultaneously. The cylinder works for compression, the lubricating cylinder for lubricating and cooling each component, and the transmission shaft directly drives the rotor to rotate and do work.

Description

technical field [0001] The invention relates to a novel compressor, a pump and pneumatic equipment, in particular to a compressor with a large power-to-weight ratio, no vibration, and applied to large, medium and small equipment. Background technique [0002] At present, among the existing compressors, there are mainly reciprocating piston compressors, rotary compressors, scroll compressors, and screw compressors. [0003] Disadvantages of piston compressors: complex and heavy structure, vibration during machine operation, discontinuous exhaust, and pulsation of air flow; disadvantages of rolling rotor compressors: large leakage, friction and wear between the sliding vane and the cylinder wall, compression The volume is small; the manufacturing cost of the scroll compressor is high, eccentric vibration, and the surface of its moving parts is mostly in the shape of a curved surface.

[0003] Disadvantages of piston compressors: complex and heavy structure, vibration during machine operation, discontinuous exhaust, and pulsation of air flow; disadvantages of rolling rotor compressors: large leakage, friction and wear between the sliding vane and the cylinder wall, compression The volume is small; the manufacturing cost of the scroll compressor is high, eccentric vibration, and the surface of its moving parts is mostly in the shape of a curved surface. The processing and inspection of these curved surfaces are more complicated, and the manufacturing requires high-precision processing equipment and precise adjustment. Center assembly technology, so the manufacturing cost is high, between the moving parts or between the moving parts and the fixed parts, often maintain a certain movement gap to achieve sealing, the gas passing through the gap will inevitably cause leakage, which limits the rotary type It is difficult for compressors to achieve a large compression ratio. Therefore, most rotary compressors are mostly used in air-conditioning conditions; screw compressors have high compressor noise and cannot be used in high-pressure situations. Screw compressors rely on gaps to seal gas. Does not have superior performance in the small volume range
