Description

Cam rotor sliding vane compressor

Technical Field

The utility model relates to a gas compressor, in particular to a cam rotor sliding vane type compressor.

Background

At present, most of widely used gas compressors are reciprocating piston compressors, and the problems of large vibration, large noise, complex structure, heaviness and high manufacturing cost exist in the operation.

Disclosure of Invention

The utility model provides a cam rotor sliding vane compressor for overcoming the problems, which has simple structure and high working efficiency.

The utility model comprises a cam and a shell, and adopts the technical scheme that: divide into two sets of chambeies by cam, upper and lower gleitbretter with the casing inner space, promptly: the rotary shaft drives the cam to rotate clockwise, low-pressure gas enters from the gas inlet pipe, high-pressure gas is discharged from the gas outlet pipe, and the operation mode of the equipment is a compressor mode.

In the above technical scheme: the upper and lower sliding sheets are provided with a plurality of springs to enable the end parts of the upper and lower sliding sheets and the curved surface of the cam to form a closed line.

When the rotating shaft drives the cam to rotate clockwise, the air inlet pipe is used for high-pressure air inlet, the air outlet pipe is used for low-pressure air outlet, and the operation mode of the equipment is an expander mode.

When the rotating shaft rotates clockwise, the air inlet pipe is used for high-pressure air inlet, and the air outlet pipe is used for low-pressure air outlet. The utility model can be used as an expander. The utility model has the advantages of simple structure, stable operation, small vibration, low noise, easy manufacture, low cost, long service life and high operation efficiency.

Drawings

The utility model is further described in detail below with reference to the figures and examples.

FIG. 1 is a schematic view of the structure of the present invention.

In the figure: 1. rotating shaft, 2, cam, 3, air inlet pipe, 4, shell, 5, front working chamber, 6, spring, 7, upper and lower sliding sheets, 8, rear working chamber, 9 and exhaust pipe.

Detailed Description

FIG. 1 shows: the space in the shell 4 is divided into two groups of chambers by the cam 2 and the upper and lower sliding sheets 7, namely: preceding working chamber 5, back working chamber 8, when axis of rotation 1 drove cam 2 clockwise rotation, low pressure gas got into from intake pipe 3, and high-pressure gas discharges from blast pipe 9, and equipment operation mode is the compressor mode. The upper sliding sheet 7 and the lower sliding sheet 7 are provided with a plurality of springs 6, so that the end parts of the upper sliding sheet 7 and the lower sliding sheet 7 and the curved surface of the cam 2 form a closed line. When the rotating shaft 1 drives the cam 2 to rotate clockwise, the air inlet pipe 3 is used for high-pressure air inlet, the air outlet pipe 9 is used for low-pressure air outlet, and the operation mode of the equipment is an expander mode. The inner surface of the shell 4, the binding surfaces of the upper sliding sheet 7, the lower sliding sheet 7 and the cam 2 are made of graphite materials.

When the utility model is used as a compressor, when the rotating shaft 1 drives the cam 2 to rotate clockwise, the volume of the front working chamber 5 is continuously reduced, the gas in the chamber is continuously compressed, and the pressure is gradually increased. When the pressure of the gas in the chamber rises to a certain set value, the gas is discharged through the gas discharge pipe 9, thereby realizing the compression and discharge processes of the gas.

The rear working chamber 8 realizes the air suction process while the compression and exhaust processes of the air are realized. When the cam 2 rotates clockwise, the volume of the rear working chamber 8 increases continuously, the pressure of the air in the chamber will decrease, and thus the outside air will be sucked into the rear working chamber 8 through the duct 3, thereby completing the suction process.

When the present invention is used as an expander, high-pressure gas is introduced from the line 3, and expanded low-pressure gas is discharged from the line 9. The specific working process is as follows:

when a certain amount of high-pressure gas is introduced into the rear working chamber 8 through the pipeline 3, as the cam 2 rotates clockwise, the volume of the rear working chamber 8 is increased continuously, so that the gas in the chamber is expanded continuously to push the cam 2 to do work, and the processes of gas intake and expansion work in the rear working chamber 8 are completed.

When the air completes the work of air intake and expansion, the low-pressure air in the front working chamber 5 can be discharged out of the machine through the exhaust pipe 9 because the volume in the chamber is continuously reduced, thereby completing the exhaust process.
