Abstract

The invention relates to a double-cylinder rotary compressor. The rotary compressor comprises an outer air cylinder, an ellipse rotor, and an inner air cylinder which are concentrically installed, wherein an inner short shaft of the ellipse rotor is equal to the outer diameter of the inner air cylinder, and an outer long shaft of the ellipse rotor is equal to the inner diameter of the outer air cylinder; the external surface of the ellipse rotor and the inner wall surface of the outer air cylinder are tangent at any kinetic instant, the internal surface of the ellipse rotor and the outer side wall of the inner air cylinder are tangent, the inner air cylinder and the outer air cylinder are respectively provided with two pairs of slip sheets; the inner air cylinder is provided with two pairs of air inlet cavities and exhaust cavities; crescent volume is divided into two pairs of air inlet (liquid) cavities and compressing, exhaust (liquid) cavities by the inner air cylinder and the outer air cylinder so as to form four pairs of corresponding working volumes; and the inner air cylinder and the outer air cylinder are respectively provided with four pairs of air inlet ports and exhaust (liquid) ports. The double-cylinder rotary compressor provided by the invention has the advantages of high efficiency, no vibration, small volume, uniform stressing of a main shaft, small gas pulsation, simple structure, is stable in operation, and eliminates unbalanced force caused by rotation; and the double-cylinder rotary compressor can be used in different gas compressors, fluid pumps and vacuum pumps.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a double-cylinder rotary compressor which can be used in the fields of compression of various gases, transportation of fluids, mixed transportation of oil and gas, and vacuum pumps. Background technique [0002] Compressors and fluid pumps are general-purpose machinery widely used in various fields such as machinery, chemical industry, transportation, air conditioning and refrigeration, and national defense construction. Especially in the field of refrigeration and air conditioning, compressors are important heart equipment; in oilfield exploitation, the multiphase long-distance transportation of crude oil, associated gas and water is a technical problem in oilfield mixed transportation, especially in mountainous, desert and offshore oilfields. Mixed transportation pump is a research hotspot. The mixed transportation of oil and gas can not only save costs, simplify the process flow and impr...
