Abstract

A rotor compressor, when the compressor has a single cylinder, comprises a cylinder body stator. A front end cap and a rear end cap are arranged on the front end face and the rear end face of the cylinder body stator. An eccentricity rotor that has a moving ring is arranged in the cylinder and does rotary motion around a central shaft, forming a crescent empty cavity. The crescent empty cavity isseparated into a high-pressure cavity and a low-pressure cavity by a separating device of a high-pressure cavity and a low-pressure cavity. A rotary shaft of the separating device is integrated with a stop dog. The rotary shaft of the stop dog is hidden in a shaft hole of radial cut opening of a stator inner cavity. The separating device is restrictively driven by a fixed cylinder of the moving ring on the rotor through a connector and does fan-shaped swing around the center of the open shaft hole to realize input and output liquid.

Description

Rotor-type compressor

Technical field:

The present invention relates to the energy conversion device that a kind of mechanical energy changes the pressure ability into, particularly a kind of rotor-type compressor.

Background technique:

Although existing rotor-type compressor has the incomparable advantage of other kind compressors; But owing to existing the processing technology complicacy, sealing insecure shortcoming; Especially the reliability of mechanical structure and sealing greatly reduces when volume strengthens, and therefore is difficult to improve swept volume.Cause the main cause of above-mentioned shortcoming to be that the separation block the sphere of activities of activity of separates chamber and low pressure chamber is little, reliability is relatively poor, when realizing increasing swept volume, processing technology is difficult to realize more.

Goal of the invention:

The object of the present invention is to provide rotor-type compressor, it can realize sealing more reliably between hyperbaric chamber and low pressure chamber, and can under the prerequisite of equal volume, weight, significantly increase swept volume.

Technological scheme:

To achieve these goals, the invention provides rotor-type compressor, when it is the single cylinder structure, comprise a cylinder body stator; Be assemblied in the front and rear cover on the cylinder body stator front/rear end; One is configured in the eccentric rotor that has rotating ring that cylinder interior rotates around central shaft, forms the crescent shape cavity; The separating device of one hyperbaric chamber and low pressure chamber is divided into hyperbaric chamber and low pressure chamber with the crescent shape cavity; The rotatingshaft and the block of separating device are integrated; The rotatingshaft of block is contained in the axis hole of the radially deep opening of bore of stator; Separating device has restrictedly through link under the drive of the stationary cylinder of epitrochanterian rotating ring; Separating device is that fan-shaped swing is done in the center of circle with the axis hole of opening, is accomplished the suction and the discharge of convection cell; The rotatingshaft of separating device is removed with the end face of end cap and is kept having no association outside the necessary axial fit clearance;

The suction port and the exhaust port of fluid are set in the front and back of the circumferencial direction of above-mentioned separating device; Suction port and exhaust port can be arranged on the stator, also can be arranged on the end cap.

According to one aspect of the invention, the block shaft of separating device, block can adopt any way to be fastenedly connected, and the hole in the cylindrical body center of circle is used for connector member, make the separating device of separates chamber and low pressure chamber and rotating ring remain coupled condition.

According to another aspect of the present invention, the link that connects separating device should be swung in the scalloped recess of cylindrical body both ends of the surface, and the opening of scalloped recess realizes being divided into prerequisite to guarantee hyperbaric chamber and low pressure chamber.

Another aspect of the present invention, described rotor-type compressor can be the multi-cylinder structures; In the multi-cylinder structure, realize that dynamic balancing is just passable as long as guarantee arranging of rotor.

Beneficial effect:

Because the separating device that the present invention adopted makes the volumetric efficiency of rotor-type compressor be greatly improved, structure is simpler, and manufacturability is more superior, and the condition of mechanical motion is especially reasonable, can further realize low noise, shockproof.

The drawing explanation:

Fig. 1 is a first embodiment of the present invention cross-section profile;

Realize the preferred embodiments of the present invention:

As shown in Figure 1, the rotor-type compressor of first embodiment of the invention comprises a cylinder block stator 1 and the eccentric rotor 3 that rotates around the axle center that has rotating ring 4, and rotor 3 is by key 5 circumferencial direction location on axle 2; Rotor 3 in motion as shown in the figure by block shaft 10, the block 11 of separating device; To be fixed on through link 7 that cylindrical body 6 links together on the rotating ring 4; Airtight crescent shape cavity is separated into hyperbaric chamber and low pressure chamber; Suck fluid by low pressure chamber suction port 12, will discharge fluid through the exhaust port 9 of hyperbaric chamber through the check valve 8 of any structure thereafter.

In conjunction with Fig. 1, provide each toponym of the present invention:

1. cylinder body stator;

The axle;

3. rotor;

4. rotating ring;

5. key;

6. cylindrical body;

7. link;

8. check valve;

9. exhaust port;

10. block shaft;

11. block;

12. suction port;

More than combine accompanying drawing and embodiment to describe the present invention; But those skilled in the art is to be understood that; The foregoing description only is an exemplary and nonrestrictive, under the condition that does not deviate from spirit and scope of the invention, can make all improvement to the foregoing description.For example: the shape of block and bearing are selected and can be adjusted according to practical application.
