Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a scroll compressor static disk to solve the problem of the upper end surface of the movable scroll profile part of the movable scroll and the static scroll of the fixed scroll in the existing scroll compressor. After the lower end surface of the profile part is worn, the axial clearance cannot be automatically compensated, and the amount of oil in the oil and gas is too much or contains impurities, which will easily lead to the static scroll profile of the fixed scroll and the orbiting scroll profile of the movable scroll. The problem of the part being crushed and broken

Embodiment 1

[0020] What the present invention refers to refers to such as figure 1 and Figure 4 The exhaust direction of the exhaust port 2-2 of the static disc seat shown.

[0021] Such as figure 1 , figure 2 and image 3 The scroll compressor static disk shown includes a static disk seat 2, a casing 9, a movable scroll 7 and a fixed scroll 6, and the lower end of the static disk seat 2 of this embodiment is connected to the casing 9 through six bolts 4. The upper end of the connection; such as Figure 5 The shown static scroll 6 includes a static disk body, which has a static disk connection disk part 6-2 and a static scroll profile part 6-1 connected to the lower end of the static disk connection disk part 6-2; The scroll 7 includes a moving disk body, the moving disk body has a moving disk connection part and a movable scroll profile part arranged at the upper end of the moving disk connection part, and the moving scroll 7 passes through the small bearing of the moving disk on ...

Embodiment 2

[0023] In this embodiment, the retreat gap s1 between the upper end surface of the static disk connecting disk part 6-2 of the fixed scroll disk 6 and the lower end surface of the static disk seat 2 is 0.1 mm; the static disk connecting disk part of the fixed scroll disk 6 The floating gap s2 between the lower end surface of 6-2 and the bottom surface of the positioning round hole 9-1 of the casing 9 is 0.03 mm; the pin-hole matching gap n is 0.04 mm; The disc hole matching gap r between the static disc connecting disc parts 6-2 of the scroll disc 6 is 0.105 mm; other features are the same as in the first embodiment.

[0024] When working, the oil and gas enter the low-pressure chamber through the air inlet of the compressor, and then enter the compression chamber where the fixed scroll profile of the fixed scroll and the movable scroll profile of the movable scroll are screwed and meshed from the low pressure cavity. When the circulation system causes too much oil or impuriti...

Abstract

The invention discloses a static disc of a scroll compressor, and relates to the technical field of scroll compressor manufacturing. The static disc comprises a static scroll disc, wherein a recedinggap between the upper end face of a static disc connecting disc part of the static scroll disc and the lower end face of a static disc seat is 0.05 mm-0. 1 mm, a floating gap between the lower end surface of the static disc connecting disc part and the bottom surface of a positioning circular hole of a shell is 0.01-0.03 mm, and a plurality of guide limiting pins extending into the static disc seat are arranged on the upper end surface of the static disc connecting disc part. Compared with the prior art, the static disc can solve the problems that after the upper end face of a movable scroll molded line part of a movable scroll disc and the lower end face of a static scroll molded line part of a static scroll disc of an existing scroll compressor are abraded, an axial gap cannot be automatically compensated, and the static scroll molded line part of the static scroll disc and the movable scroll molded line part of the movable scroll disc are easily broken off caused by extrusion causedby too much oil in oil gas or impurities.

Description
