Problems solved by technology

[0003] In a scroll air compressor, the scroll plate of the moving disk and the tooth line of the static disk move relatively quickly during operation. If the processing accuracy is not enough, the top of the tooth of the moving disk or the bottom of the tooth of the static disk are slightly deformed, it will cause contact wear between the above two , serious cases will cause the compressor to be scrapped

Embodiment 1

[0029] Such as Figure 1 to Figure 6 As shown, the static disk structure of the environment-friendly silent scroll air compressor is composed of a static disk body 1, a barrel body 2, a connecting frame 3, a spring 4, and the like.

[0030] Among them, such as figure 1 with Image 6 As shown, the static disk body 1 is in the shape of a barrel, and the static disk body 1 is provided with a helical wire tooth 1a, and the wire tooth 1a and the static disk body 1 are of an integrated structure. A spiral air groove 1b is formed between the wire teeth 1a and the inner wall of the static disk body 1, and the middle part of the bottom wall of the static disk body 1 is penetrated with an exhaust hole 1c communicating with the end of the air groove 1b, and the static disk body 1 An air suction hole 1d communicating with the head end of the air groove 1b is opened through the side wall.

[0031] Such as Figure 2 to Figure 5 As shown, the bottom wall of the head end of the air groove...

Embodiment 2

[0039] The structure and principle of this second embodiment are basically the same as that of the first embodiment, except that the plugging member 10 is a columnar rubber plug inserted into the oil injection hole 2c, and the side wall of the rubber plug is in contact with the oil injection hole 2c. The wall of the hole is tightly against, and the outer end of the rubber plug protrudes from the oil hole 2c.

Abstract

The invention provides an environment-friendly mute type static disc structure of a vortex air compressor, and belongs to the technical field of machinery. The environment-friendly mute type static disc structure solves the problem that the service life of an existing static disc is short. The environment-friendly mute type static disc structure comprises a barrel-shaped static disc body, whereinspiral linear teeth are arranged in the static disc body; a spiral gas slot is formed between the linear teeth and the inner wall of the static disc body; a circular hole is formed in the bottom wallat the front end of the gas slot in a penetrating mode; the bottom of the static disc body is fixedly equipped with a barrel body; the circular hole communicates with the barrel body; a connecting frame with a T-shaped section is arranged in the barrel body; the connecting frame is composed of a rod part and a circular head part, wherein the head part is positioned in the circular hole; the top wall of the head part is flush to the bottom wall of the gas slot; a spring sleeves outside the rod part; an oil cavity is formed between the head part and the barrel body; an oil injecting hole which communicates with the oil cavity is formed in the side wall of the barrel body in the penetrating mode; and a plurality of strip-shaped oil discharge holes are formed in the head part in the penetrating mode. The environment-friendly mute type static disc structure has the advantage of being long in service life.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a scroll air compressor, in particular to a static plate of an environment-friendly and silent scroll air compressor. Background technique [0002] Scroll air compressors are widely used in industrial, agricultural, transportation and other industries where compressed air is needed due to their high efficiency, low noise, small size, and benefits for energy saving and environmental protection. The main moving parts of the scroll air compressor are only the meshing between the scrolls, the relative speed is low, and there are no vulnerable parts such as suction and exhaust valves, so the service life is longer than that of the piston and screw compressors. It is an ideal power source for pneumatic machinery. In a scroll air compressor, the scroll disk of the main moving part is divided into a moving disk and a static disk, and a scroll plate is arranged inside the moving disk and ...
