Preferably, bearing or axle sleeve are equipped between the hollow shaft and casing.

Preferably, bearing or axle sleeve are equipped between the line shaft and casing.

It preferably, is the intensity for increasing hollow shaft, hollow axis center can be equipped with mandrel, and mandrel passes through guide vane and sky Mandrel inner wall is fixed.

Preferably, there are two types of the set-up modes of the mandrel, one is be positioned only in hollow shaft；Another kind is mandrel One end extends on the disk cover where line shaft.

The utility model has the beneficial effects that:

(1) revolving speed is high, and flow is big, continuous exhaust pneumatic wallop, no pulse；

(2) structure is simple, at low cost, is suitble to large-scale production；

(3) components are considerably less, and without vulnerable part, physical life is extremely long；

(4) small, low noise is shaken, is operated very steady；

(5) do not have to be installed into, exhaust valve, no internal leakage；

(6) due to being full rotation, unique friction part is the operating friction of bearing；

(7) the advantages that low energy consumption, and Energy Efficiency Ratio is high, energy-saving and environmental protection.

Specific embodiment

In order to which the technical characteristics of the utility model, purpose and beneficial effect are more clearly understood, now to this reality Following detailed description is carried out with novel technical solution, but should not be understood as the restriction to the enforceable range of the utility model.

As shown, a kind of centrifugation variable displacement type compressed gas compressor, including casing 1, compact disk 2；It is characterized in that institute Stating 1 inner cavity of casing is barrel shaped structure；Axis hole 1-1 is offered at the 1 both ends medium position of casing, and is opened on casing 1 is leaned to one side Equipped with gas vent 1-2, for compressed gas to be discharged to the external world；2 two sides of compact disk be button type dish type disk cover 2-1, two It is fixed between disk cover 2-1 by dike shape blade 2-3, disk cover 2-1 and dike shape blade 2-3 form an entirety, in 2 high speed of compact disk In rotary course, gas can be got rid of the gas in compact disk 2 due to being subject to centrifugal forces to compression plate edge, compact disk 2 The volume at middle part to the edge of compact disk 2 constantly reducing, gas is constantly extruded in this process, forms compressed gas Body is respectively equipped with hollow shaft 3 and line shaft 4 in two two sides disk cover 2-1, and hollow shaft 3 can make outside air enter compact disk 2 It is interior, and bearing or axle sleeve are installed in compact disk 2 and 1 installation place of casing；The compact disk 2 is mounted in casing 1；It is described dynamic Power axis 4 is connect with power source.

It further, is the intensity for increasing hollow shaft 3,3 center of hollow shaft can be equipped with mandrel 6, and mandrel 6 passes through water conservancy diversion leaf Piece 5 is fixed with 3 inner wall of hollow shaft, and flow deflector can not only increase the intensity of hollow shaft, moreover it is possible to air be promoted to enter compact disk 2 In；There are two types of the set-up modes of the mandrel 6, and one is be positioned only in hollow shaft 3；Another kind is that one end of mandrel 6 extends To the disk cover 2-1 where line shaft 4, the latter's intensity is bigger.

The principles of the present invention, the line shaft 4 in compact disk 2 make compact disk 2 generate high speed to revolve by external connection power source Turn, at this moment the gas in compact disk 2 is discharged compact disk 2, makes to form negative pressure in compact disk 2；Ambient atmos pass through compression at this time Hollow shaft on disk 2 is inhaled into compact disk 2, since compact disk 2 constantly rotates at high speed, is generated very big centrifugal force, is made The gas of sucking is due to the effect of centrifugal force constantly from getting rid of to 2 edge of compact disk in the middle part of compact disk 2；It compresses in above process Effect of the gas of disk 2 not only by dike shape blade 2-3 increases its kinetic energy enough, simultaneously because dike shape blade 2-3, volume is not Disconnected variation, volume are gradually reduced by the middle part of compact disk 2 to edge, make gas during compact disk 2 are discharged constantly by It squeezes, then the final compact disk 2 that is discharged is discharged to outside casing 1 by the gas vent 1-2 on casing 1 again into casing 1.

Pass through the principles and methods of above-mentioned method and compressor, it can be seen that the utility model is that velocity profile is centrifugal Air compressor and carried displacement air compressor are organically fused together, so that the method for compressed gas and compressor produce Change substantially.

Although the utility model is described in detail referring to previous examples, come for those skilled in the art It says, still technical solution documented by foregoing embodiments can be carried out and be modified, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done, It should be included within the scope of protection of this utility model.
