Abstract
The utility model relates to planar worm-groove rotary vane type machinery which comprises a main case, a rotor and two impellers, wherein the main case is a round box type structure piece, and worm grooves are formed in the inner walls of the upper round face and the lower round face of the main case; the rotor is a round cake type structure piece and is installed in the main case through a rotary shaft; the two impellers are movably embedded into the rotator side by side and are respectively engaged with the worm grooves in the two opposite round faces of the inner walls of the main case, and the two impellers can respectively rotate along the radial direction of the rotor. When the rotor rotates, the two impellers rotate along with the rotor and also respectively move along the molded lines of the worm grooves of the main case, and therefore the suction, compression and discharge of media are realized. The planar worm-groove rotary vane type machinery not only can serve as a compressor but also can serve as a hydraulic pump or a pneumatic motor. The planar worm-groove rotary vane type machinery has the advantages of simple structure and wide range of application.
Description
Technical field
The utility model relates to a kind of mechanical structure, relates in particular to a kind of plane snail groove rotary vane type machinery.
Background technique
The ubiquitous problem of single screw compressor of prior art is that screw rod and star-wheel are all to do rotatablely moving of high speed when work, due to the effect of high speed centrifugation power, make its friction surface be not easy to form lubricant film, and unstable wear reduce working life.
The scarcely sliding vane of hydropneumatic motor of prior art, its slide plate is easily stuck in leaf groove, because slide plate is reciprocating in leaf groove, therefore easily wearing and tearing.
The piston motor of prior art is due to its complex structure, bulky, and has the problem that manufacture cost is too high.
Model utility content
The purpose of this utility model, the problem existing in order to solve above-mentioned prior art exactly, provides a kind of plane snail groove rotary vane type machinery.
To achieve these goals, the utility model has adopted following technological scheme: a kind of plane snail groove rotary vane type machinery, and it comprises:
Casing, is circle case type constructional element, and its upper and lower two disc inwalls are provided with snail groove;
Rotor, is patty structural member, and it is arranged in casing by rotating shaft;
Two impellers, side by side movable be inlaid on rotor and respectively the snail groove engagement on two discs relative to casing inner wall be connected, two impellers can be respectively along the radial rotating of rotor, when rotor rotates, two impellers are when rotating with rotor, also along the molded line of casing snail groove, move respectively, thereby realize suction, compression and the discharge of medium.
On described impeller, be evenly interval with four sectors.
Described casing is provided with four suction ports and four air outlets, four suction ports and four air outlets are separately positioned on two discs up and down of casing, wherein two suction ports and two air outlets are corresponding to an impeller, and another two suction ports and another two air outlets are corresponding to another impeller.
On a diameter line of described rotor, be arranged with two grooves that axially connect, described two impellers are arranged on respectively in two grooves, and to the both sides of rotor, stretch out respectively.
Plane snail groove rotary vane type machinery of the present utility model not only can be used as compressor, also can be used as oil hydraulic pump or pneumatic motor, when the liquid of high pressure or gas arrive impeller by the seal space of snail groove and rotor, it acts on power on impeller and can promote impeller and move to exhaust port direction along the molded line of snail groove, until impeller leaves snail groove, enter into the inner space of cylindrical body rotor, swept volume and exhaust port communicate and discharge liquid or gas.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Referring to Fig. 1, coordinate referring to Fig. 2, Fig. 3, Fig. 4, plane snail groove rotary vane type machinery of the present utility model, comprises casing 1, rotor 2 and two impellers 3.
Casing 1 is circle case type constructional element, and its upper and lower two disc inwalls are provided with snail groove 10; This casing 1 is provided with four suction ports 11,13,15,17 and four air outlets 12,14,16,18, four suction ports and four air outlets are separately positioned on two discs up and down of casing, wherein two suction ports and two air outlets are corresponding to an impeller, and another two suction ports and another two air outlets are corresponding to another impeller.
Two impellers 3 side by side movable be inlaid on rotor and respectively the snail groove engagement on two discs relative to casing inner wall be connected, two impellers can be respectively along the radial rotating of rotor, when rotor rotates, two impellers are when rotating with rotor, also along the molded line of casing snail groove, move respectively, thereby realize suction, compression and the discharge of medium.On impeller, be evenly interval with four sectors 31.
Plane snail groove rotary vane type machinery of the present utility model as the working principle of compressor is, when rotor, being contained in epitrochanterian impeller also rotates along the snail groove in casing, due to rotor seal the space between casing ontology and snail groove, when impeller advances in snail groove, the space of sealing dwindles gradually, thereby realizes the compression process of medium.
Plane snail groove rotary vane type machinery of the present utility model as the working principle of oil hydraulic pump or pneumatic motor is, when the liquid of high pressure or gas arrive impeller by the seal space of snail groove and rotor, it acts on power on impeller and can promote impeller and move to exhaust port direction along snail groove, until impeller leaves snail groove, enter into the inner space of rotor, swept volume and exhaust port communicate and discharge liquid or gas.
