Description
Technical field
The present invention relates to a kind of compressor, sliding-vane compressor that especially a kind of cylinder is rotated with rotor.
Background technique
Piston compressor due to be it is reciprocating, the unbalance mass, of crankshaft affects its even running, and noise is larger.Spiral shell
Rod-type compressor arrangement is more complicated, it is impossible to be used in miniature occasion, and it is only used for mesolow range.Sliding-vane compressor structure
Simply, manufacture is easy, Operation and maintenance easy maintenance, almost without friction and axial force, but its major defect is slide plate and rotor
There is very big mechanical friction between cylinder, generates biggish energy loss, therefore its efficiency is than screw and reciprocating compressor
All low 10% or more.
Summary of the invention
The present invention, which provides one kind, can reduce friction loss and improve the slide plate that the cylinder of compressor efficiency is rotated with rotor
Formula compressor.
The present invention adopts the following technical scheme:
A kind of sliding-vane compressor that cylinder is rotated with rotor is set in cylindrical chassis including the cylindrical chassis with pedestal
It takes offence cylinder and cylindrical chassis and cylinder coaxial arrangement of taking offence, is equipped with rotor in cylinder of taking offence and the cylinder of taking offence is set with rotor eccentricity
It sets, air inlet and air outlet is equipped on the left side of casing, also, the air inlet is located at crescent moon between cylinder and rotor of taking offence
The position changed from small to big in rotor rotation direction in the gap area of shape, gas outlet are located at crescent between cylinder and rotor of taking offence
Gap area in position in rotor rotation direction from large to small；The square of >=8 even number item axial directions is uniformly distributed on rotor
Shape groove is equipped with compressed spring, respectively at least provided with 2 radial through-hole in every group of opposite rectangle groove in radial through-hole
Corresponding radial through-hole communicates rectangle groove respectively, each rectangle groove be respectively embedded into the slide plate isometric with rotor and its
In have the insertion of 1 piece wide slide plate take offence the inside wall of cylinder dovetail groove in, so that rotor is taken offence cylinder by the take offence wide slide plate of cylinder of insertion
It rotates synchronously, remaining slide plate is inconsistent with the inner wall for cylinder of taking offence under the action of compressed spring and centrifugal force.
Compared with prior art, the present invention has the advantage that
1. solving cylinder and slide plate with the rotor method that combines with sliding-vane compressor technology of rotation using cylinder
Wear problem.Since the relative speed difference between the turntable and slide plate of take offence cylinder and rotor when following rotation is smaller, thus rub
Wearing, it is smaller to lose, and compressor efficiency is higher.
2. cylinder of taking offence using right end closing left end open structure, convenient in casing left side plate correspond to take offence cylinder with turn
The biggish position changed from small to big in rotor rotation direction in the gap area of crescent between son is arranged from round hole transition
It is arranged for the import in shape hole of dripping and in lesser position from large to small from the outlet that the transition of shape hole is round hole of dripping, so that
Compressor take offence cylinder structure and supporting way simplify；Meanwhile the area that will be covered at the shape hole of dripping of air inlet and air outlet
Domain is designed as being slightly larger than the scheme of sector angle folded by 1 times and 2 times of adjacent slide plates respectively, it is ensured that is not interrupted showing for air inlet
As, and exhaust outlet fluid pulsation phenomenon is mitigated as far as possible；It can guarantee at least there is one between air inlet and air outlet simultaneously
A transition chamber thereof between high pressure and low pressure, to reduce internal leakage.The cabinet parts of the present invention program and cylinder of taking offence turn
Reasonable guarantee can be obtained in gap between disk and slide plate, and can make under the reaction force of high pressure gas to avoid cylinder or rotor
Axial float, each structural member uniform force, gap adjustment is easy to control, and manufacture is easy.Using the present invention program, can fill up
In Rotary Compressor field, small flow high pressure than compressor product blank.
3. boring multiple radial through-hole in opposite sliding vane groove on armature spindle can be periodical in sliding vane groove with buffer slip
Effect is inflated in moving process, the volume in each slot can be made always to hold in shifting as main pipe by center hole
Product is basically unchanged, and reduces drag losses, while being also convenient for lubricating method appropriate, the friction loss of reduction slide plate and slot.It can
To reduce the requirement to lubrication, it might even be possible to oil-free lubrication, and service life is longer.
4. mechanical seal only needs 1, and because the pressure that it is born is lower, to the of less demanding of mechanical seal.
