Abstract
The utility model relates to a dual-working-cavity sliding vane type compressor, which comprises a rotor, a cylinder body, a sliding vane, a flyweight, a pull rope, a front end cap and a rear end cap, wherein a cylinder hole is arranged on the cylinder body, and two working chambers are surrounded by the cylinder hole, the rotor and the end caps; the rotor is positioned in the cylinder hole and is provided with a slideway forming a sliding fit with the sliding vane; the flyweight is connected with the sliding vane by the pull rope. When the rotor rotates, the sliding vane is thrown out of the slide way under the centrifugal force and slides on a mold surface contacting tightly with the cylinder hole. Meanwhile, the flyweight also generates outward centrifugal force because of rotation and acts on the sliding vane by the pull rope, so that reverse pull effect to the sliding vane is formed. The utility model reduces the contact force between the sliding vane and the cylinder hole, reduces the friction and the abrasion between the sliding vane and the cylinder hole, and extends the service life of the compressor and increases the mechanical efficiency.

Background technique
Sliding-vane compressor has little, the in light weight and advantages of simple structure and simple of volume, be widely used in all gases compression device, refrigeration plant and the air conditioner, double working-chamber sliding-vane compressor wherein is because can significantly reduce the radial load of gas to rotor bearing, and air displacement is bigger, thereby is subjected to people's special concern.The structure of traditional double active chamber sliding-vane compressor with working principle is: offer some the flat grooves parallel with rotor axis on a columned rotor, special situation is that these flat grooves are disposed radially; Cylinder-bore is made of specific cylinder profile, the combined type molded lines that cylinder profile is common has simple harmonic quantity function molded lines, elliptic function molded lines, spline function molded lines and high power function type line or the like, cylinder profile also to have to adopt the different combination of function of plurality of sections to form; Rotor is placed in the cylinder, surrounds two active chambers by rotor, cylinder-bore and the front and rear cover that is arranged on cylinder two ends places; The blade of flat is placed in interior and sliding with it the joining of flat chute of rotor, and when rotor rotation, slide plate is thrown away from chute by action of centrifugal force, and its outer end is close to the cylinder profile and is slided; But two adjacent slide plates and rotor, cylinder and end cap etc. constitute the work primitive that the volume cycle changes, and are aided with suitable suction port and relief opening and promptly constitute a compressor.The shortcoming of above-mentioned sliding-vane compressor is: the contact force of slide plate and cylinder profile is big, causes bigger wearing and tearing and the energy loss of generation between slide plate and the cylinder-bore, so working life and mechanical efficiency are lower.
Summary of the invention
The utility model provides a kind of double working-chamber sliding-vane compressor at existing the problems referred to above in the prior art, and its purpose is to reduce the friction and wear between slide plate outer end and the cylinder profile, thereby improves the working life and the mechanical efficiency of compressor.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double working-chamber sliding-vane compressor is provided, and this compressor comprises a rotor, a cylinder body, two end caps and several slide plates; Described rotor has a cylindrical outer surface, and the two ends of rotor are supported on respectively on the described end cap with bearing structure, offer the chute of some flat on the rotor, disposes a slide plate in each chute accordingly, and slide plate and chute are the state of being slidingly matched; Offer cylinder-bore on the cylinder body, the profile of cylinder-bore is by generating such as molded lines such as simple harmonic quantity function, elliptic function, spline function or high power functions; Rotor is placed in the cylinder-bore, constitutes two active chambers between rotor outer surface, cylinder-bore profile and the both sides end cap, it is characterized in that being provided with the special piece that flies, and the described piece that flies is connected with slide plate with stay cord.
The utility model adopts and flies block assembly, when rotor rotation, fly piece and produce outside centrifugal force, this centrifugal force acts on the slide plate and to slide plate by stay cord and forms the effect of pulling back, thus partial offset the outer mental and physical efforts that throw away of slide plate, alleviated the contact force of slide plate and cylinder profile, the result has reduced the friction and wear between slide plate and the cylinder profile, has improved the working life and the mechanical efficiency of compressor.
