Embodiment Construction

[0017] Such as figure 1 Shown: a multi-line scroll with a discharge device of a scroll compressor, the composition of the multi-line scroll: on a plane, a plurality of scroll lines are divided into 360° by the central point 1 of their expansion Formed, because the average value of 360° is different, the average angle of the multi-vortex lines is also different, so the average angle of the multi-vortex lines is 360°÷the number of multi-lines; the vortex on the multi-line scroll disk The length or the number of turns can be long or short. The vortex line that expands more than 360° is a long vortex line, and the vortex line that is less than 360° is a short vortex line; , can be divided into two types: multi-line static scroll and multi-line movable scroll. According to the form of composition, the static and movable scrolls are composed of the disk surface 6 and the side wall 5, which are perpendicular to the disk surface and the end surface is parallel to the disk surface. Co...

Abstract

This invention relates to whirl compressor multi-line whirl disc, which gets multiple whirl lines by single whirl line for 360 degrees, wherein, whirl discs on compressor comprise double line whirl disc, three-line whirl disc and four-line whirl disc; the static disc multiple lines are connected on extension center into one part; the dynamic disc multiple lines are connected on extension center into one part.

Description

technical field [0001] The invention is a fluid variable capacity mechanical device. It relates to a scroll compressor, in particular to a scroll disc of the scroll compressor. Background technique [0002] The scroll disk of the existing scroll compressor is mostly composed of a single scroll wire. This kind of compressor has the following disadvantages: ①The pitch of the single scroll is large, and the radial and axial forces are concentrated; , the timeliness is low. Contents of the invention [0003] The purpose of the present invention is to break through the convention that the scroll disk is composed of a single scroll wire, and provide a novel multi-thread scroll disk for the scroll compressor. [0004] Specifically: a multi-line scroll with a discharge device for a scroll compressor. The composition of the multi-line scroll: on a plane, a plurality of scroll lines are divided into 360° by the central point of their expansion. Formed, because the average value ...
