Description

Rotor compressor

Technical Field

The utility model relates to a compressor technical field especially relates to a rotor compressor.

Background

Conventional compressor systems are widely used to compress gases and find application in many commonly employed technologies ranging from refrigeration units to jet engines. The basic purpose of a compressor is to deliver and compress a gas. To this end, compressors typically apply mechanical energy to a gas in a low pressure environment and deliver the gas to a high pressure environment and compress the gas at the high pressure environment, the compressed gas from the high pressure environment being available for work or as an input to a downstream process that utilizes the high pressure gas. Gas compression technology is well established and varies from centrifugal machines to mixed flow machines to axial flow machines. Conventional compressor systems, while very useful, are limited by the relatively low pressure ratios that can be achieved with a single stage compressor. Where a high overall pressure ratio is required, a conventional compressor system comprising a plurality of compression stages may be employed. However, conventional compressor systems including multiple compression stages tend to be large, complex, and costly.

And the widely adopted triangular rotor compression is adopted at present, and the patent No. 201720661960.1 discloses a triangular rotor compressor without cusp, which needs very high precision in the process of manufacturing three rotors, has very large processing difficulty and needs a great deal of time and money investment.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 to 5, the rotor compressor of the present invention includes an upper cover 1, a lower cover 2, a cylinder block 3, and a rotor 4, wherein the upper cover 1, the cylinder block 3, and the lower cover 2 are connected by bolts 5. The upper head 1 is installed at the upper end of the cylinder block 3, the lower head 2 is installed at the lower end of the cylinder block 3, the compression chamber 6 is formed in the middle of the cylinder block 3, the rotor 4 is installed in the compression chamber 6, and the upper head 1, the cylinder block 3, the rotor 4 and the lower head 2 are connected through a rotating shaft (not shown) connected with a motor. When the rotating shaft rotates, the rotor 4 can only be driven to rotate, and the upper cover 1, the lower cover 2 and the cylinder block 3 cannot rotate along with the rotation.

The cylinder block 3 has a boss 7 extending inwardly of the compression chamber 6 at the center thereof, and the rotor 4 is in tangential contact with the boss 7. When the rotor 4 is rotating, the gas inlet 8 and the gas outlet 9 can be prevented from communicating by the rotor 4 being in tangential contact with the boss 7, resulting in gas leakage.

Have the spout 10 that rotational symmetry set up on rotor 4, have gleitbretter 11 in the spout 10, the one end of gleitbretter 11 has cambered surface 12, this cambered surface 12 and compression chamber 6's inner wall contact, when rotating under the drive of rotation axis when rotating, rotor 4 is in the pivoted, and gleitbretter 11 receives centrifugal effect and opens toward the outside for cambered surface 12 and compression chamber 6's inner wall contact, thereby make gleitbretter 11 compressed gas. The chute 10 has a camber chamber 13 therein, and the camber chamber 13 is located at an end away from the camber 12. This cambered surface chamber 13 is the inner wall contact that is used for preventing the perpendicular terminal surface of gleitbretter 11 and spout 10 to cause two smooth face contactings, lead to the centre not have gaseous, be difficult to make gleitbretter 11 receive the effect of centrifugal force and break away from spout 10. The lower cover 2 is provided with an air inlet 8 and an air outlet 9.

The upper end surface and the lower end surface of the rotor 4 are provided with sealing rings 14, and the highest surface of each sealing ring 14 is higher than the highest surface of the rotor 4. That is, the height of the packing 14 is slightly higher than the height of the rotor 4, so that the packing 14 can be pressed by the upper cover 1 and the lower cover 2 when the packing 14 is mounted, thereby preventing leakage of the high-pressure gas in the compression chamber 6.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
