Description
Technical field
The present invention relates to a kind of rotary compressor, be specifically related to a kind of compression that can be used for all gases, the conveying of fluid mixes the twin-tub rotation-type compressor of defeated and field of vacuum with oil, gas.
Background technique
Compressor and fluid pump are a kind of universal machines that is widely used in every field such as machinery, chemical industry, communications and transportation, air conditioner refrigerating and national defense construction.In field of Refrigeration and Air-conditioning, compressor is important heart equipment especially; In oilfield exploitation; The heterogeneous long distances of crude oil, association G&W is that the technical barrier in defeated is mixed in the oil field, especially in the mountain area, desert and marine oil field oil-gas mixed delivery pump study focus especially, oil, gas mix defeated not only can cost saving; Simplify technological process and improve tar productivity; Also can significantly reduce because carbon emission amount that the associated gas burning is produced and recovery associated gas are saved the energy, mixing defeated visual plant is oil-gas mixed delivery pump.
What in above-mentioned field, use at present is that rolling piston compressor tool and rotor compression machinery all have a selenodont active chamber; Through slide plate selenodont active chamber is isolated into air-inlet cavity and compression chamber; The rotation of rotor or rolling piston makes air-inlet cavity and compression chamber volume produce variation, realizes air-breathing (liquid) and the exhaust (liquid) of compressed machinery.But; This traditional rolling piston compressor tool and the insurmountable problem of rotor compression machinery are: first revolution has only a volume in the compression of carrying out gas, and efficient is low, has caused the waste of the energy and the instability of electrical network; The change in torque of another one in the operation cycle is big; In order to make rotating speed even, then need a bigger flywheel balancing, increased manufacturing expense; Its two be a work cycle exhaust once, in pipeline, formed bigger gas, caused Analysis of Pipe Vibrations, influenced mechanical stability and reliability; It three is the rotor geometrical center and the rotating center decentraction of compressor with rolling rotor; There is a throw of eccentric; The machining error of crank throw can run up on the sealing surface of rotor and cylinder, has not only influenced the sealing of the outer surface and the cylinder inner wall face of rotor, has reduced volumetric efficiency; Centrifugal inertia force also can cause the vibration of machine, simultaneously the processing technology more complicated of crank shaft.
Summary of the invention
The objective of the invention is shortcoming to traditional rolling piston compressor tool and rotor compression machinery; Provide that a kind of efficient that can effectively solve traditional rolling piston compressor and rotor-type compressor is low, gas is big, the unsettled twin-tub rotation-type compressor of machine run.
For achieving the above object, the technological scheme that the present invention adopts is: comprise the outside cylinder, elliptic rotor, inside cylinder and the cylinder head that are installed in one heart on the bracket, main shaft is installed in the geometrical center of elliptic rotor; The external diameter of elliptic rotor major axis equals the internal diameter of outside cylinder; The internal diameter of elliptic rotor minor axis equals the external diameter of inside cylinder; On outside cylinder and inside cylinder, be separately installed with two outside cylinder slide plates that are oppositely arranged and two inside cylinder slide plates that are oppositely arranged; One end of two outside cylinder slide plates and the outer surface of elliptic rotor are tangent; The other end contacts with the outside cylinder sliding blade spring, and the outer surface of outside cylinder internal face, elliptic rotor and two outside cylinder slide plates form four outer swept volumes, and offers outside cylinder air inlet (liquid) mouth and outside cylinder exhaust (liquid) mouth in proper order in the upper both sides in two outside cylinder slide plates that are oppositely arranged of outside cylinder;
One end of described two inside cylinder slide plates and the internal surface of elliptic rotor are tangent; The other end contacts with the inside cylinder sliding blade spring; The internal surface of inside cylinder outer wall, elliptic rotor and two inside cylinder slide plates form four interior swept volumes; The both sides that are positioned at two inside cylinder slide plates that are oppositely arranged on the inside cylinder offer inside cylinder air inlet (liquid) mouth and inside cylinder exhaust (liquid) mouth in proper order; Wherein inside cylinder air inlet (liquid) mouth is connected with inside cylinder air inlet (liquid) chamber respectively, and inside cylinder exhaust (liquid) mouth is connected with inside cylinder exhaust (liquid) chamber respectively.
Offer two outside cylinder vane slot and inside cylinder vane slots that are used to install outside cylinder slide plate, inside cylinder slide plate on described outside cylinder, the inside cylinder relatively.
The axial length of described elliptic rotor, outside cylinder, inside cylinder, outside cylinder slide plate and inside cylinder slide plate equates.
The outside of described cylinder head also is equipped with exhausting buffer.
On described inside cylinder exhaust (liquid) mouth and outside cylinder exhaust (liquid) mouth inside cylinder outlet valve and outside cylinder outlet valve are installed all.
The present invention is provided with inside and outside two cylinders; Traditional rolling rotor and rotary compressor one changeed a work cycle to be changed one into and changes inside and outside cylinder and be respectively two work cycle; Therefore efficient is high; Four pairs of swept volumes are just arranged simultaneously in air inlet (liquid) and compression in one changes, four exhaust processes are arranged, its air displacement increases nearly four times than the compressor with rolling rotor and the rotary compressor of equal volume; The asynchronism(-nization) step that interior outside cylinder begins to compress differs 90 °, so live axle is stressed even, gas is little, and stabilization of speed need not be provided with flywheel; Because inside and outside cylinder all is provided with outlet valve, when the pressure of gas in the swept volume (fluid) reached the pressure of system's needs, gas (fluid) was then discharged by the relief opening that is arranged on the inside and outside cylinder; Avoided insufficient compression and the overcompression phenomenon in the gas compressor; Saved power consumption, also avoided the phenomenon of fluid pressurized in active chamber, so can a tractor serves several purposes; Both can be used as the compressor of all gases, can be used as fluid pump again; Because the rotating center of rotor is exactly the geometrical center of rotor, do not have uneven inertial force during work in addition, rotating speed is high, good stability, and volume is then littler, has saved manufacturing expense; Secondly, main working surface is circle, and technology is simple, good airproof performance, and fretting wear is little, the high and saving power consumption of volumetric efficiency.
