Embodiment Construction

[0016] figure 1 It is a schematic structural diagram of a single-cylinder single-rotor double-acting rotary compressor. figure 1 Among them, the cylinder 2 is fixed, and its center is concentric with the rotor 3. When the rotor 3 rotates around its own rotation center O, it is always tangent to the inner wall of the cylinder 2. The slide 5 moves along the slide groove under the action of the spring 10. , its end face is tangent to the outer surface of the rotor 3, preventing gas (liquid) from flowing through the working volume V d Leakage into working volume V s , the cylinder 2, the rotor 3 and the slide 5 have the same axial length, and the inner wall surface of the cylinder 2, the outer surface of the rotor 3 and the slide 5 divide the entire working volume into two pairs of crescent-shaped intake (liquid) chambers V s and compression cavity V d , when the rotor 3 rotates around the center of rotation O driven by the main shaft 7, V s Continuously increasing, gas (liqui...

Abstract

The invention discloses a single-cylinder dual-function rotary-type compression machinery which comprises an elliptic rotor and an air cylinder; a long shaft of the elliptic rotor equals to the diameter of the air cylinder and is concentric with the air cylinder; the rotary center of the elliptic rotor is concentric with a main shaft; the outer surface of the rotor is always tangential to the inner wall of the air cylinder; a sliding sheet is meshed with the outer surface of the rotor under the action of a spring, and divides a moon-shaped volume into a gas (liquid) inlet chamber Vs and a gas (liquid) compression and exhaust chamber Vd together with the inner wall of the air cylinder and the outer surface of the rotor, and a pair of corresponding working volumes are formed; and the air cylinder is respectively provided with two pairs of gas (liquid) inlets and gas (liquid) exhaust openings. The single-cylinder dual-function rotary-type compression machinery has the advantages of high efficiency, no vibration, stable working, small volume, uniform stress and simple structure, unbalanced force caused by rotation is eliminated; and the single-cylinder dual-function rotary-type compression machinery can be used for a compressor, a fluid pump and a vacuum pump of various gases.

Description

technical field [0001] The invention relates to a single-cylinder, single-rotor, double-acting 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] As we all know, gas compressors and fluid pumps are important general machinery, which are widely used in various fields of machinery, chemical industry, transportation, air conditioning and refrigeration, and national defense construction. Multiphase long-distance transportation of crude oil, associated gas and water is a technical problem in oilfield mixed transportation, especially in mountainous areas, deserts and offshore oilfields. The mixed transportation of oil and gas can not only save costs, simplify the process flow and increase oil recovery, but also greatly reduce the carbon emissions generated by the combustion of associated gas and recover the associated gas to save energy. ...
