Problems solved by technology

The tooth top of the movable and static scroll is provided with a sealing groove, and a sealing part is arranged inside the sealing groove. The sealing part is required to have high temperature resistance. Generally, the material of the sealing part is required to be resistant to high temperature above 200 ℃, and it has good wear resistance. In practice, During the operation of the compressor, the sealing parts are prone to high-temperature melting, which makes the whole machine unable to pump air
[0003] In order to achieve reliable operation of the whole machine, it is relatively difficult to improve the temperature resistance from the material alone, and the air cooling of the fixed and moving scrolls still cannot effectively reduce the temperature at the sealing parts, and there is also the possibility of sealing parts failure

Embodiment Construction

[0030] see in conjunction Figure 1 to Figure 6 As shown, according to the embodiment of the present invention, the part of the compressor and the cooling pipe is arranged in the sealing part of the moving disk 1 , and the cooling pipe moves synchronously with the moving disk 1 and rotates relative to the crankshaft 3 .

[0031] The sealing part of the moving disk 1 of the compressor is provided with a cooling pipe, so the sealing part 11 of the sealing part can be cooled more effectively through the cooling pipe located in the sealing part, the cooling effect is better, and the sealing part of the moving and fixed scroll is avoided. Working in a higher temperature environment is prone to wear and melting problems, which effectively prolongs the service life of the sealing component 11 and improves the overall reliability; at the same time, because the cooling pipe can move synchronously with the drive plate 1 and rotate relative to the crankshaft 3, Therefore, the setting of ...

Abstract

The invention provides a compressor. The compressor comprises a movable plate (1), a cooling tube and a crankshaft (3), wherein the cooling tube penetrates in the crankshaft (3); the cooling tube is partially arranged in a sealing portion of the movable plate (1); and the cooling tube synchronously moves along with the movable plate (1), and rotates relative to the crankshaft (3). According to thecompressor of the invention, the temperature at the position of a sealing component can be reduced effectively.

Description

technical field [0001] The invention belongs to the technical field of air compression, and in particular relates to a compressor. Background technique [0002] The maximum working pressure of the oil-free air scroll compressor is about 1.0MPa, and the pressure ratio reaches 10. When the air cooling device is used to cool the moving and static scrolls, the exhaust temperature under the maximum working pressure reaches 170°C. The tooth top of the movable and static scroll is provided with a sealing groove, and a sealing part is arranged inside the sealing groove. The sealing part is required to have high temperature resistance. Generally, the material of the sealing part is required to be resistant to high temperature above 200 ℃, and it has good wear resistance. In practice, During the operation of the compressor, the sealing parts are prone to high-temperature melting, which makes the whole machine unable to pump air. [0003] In order to achieve reliable operation of the ...
