Vortex mechanical single-disc double-stage molded line structure design method

Abstract

The invention provides a vortex mechanical single-disc double-stage molded line structure design method. The vortex mechanical single-disc double-stage molded line structure design method involves a movable vortex plate correction molded line and a fixed vortex plate correction molded line; the movable vortex plate correction molded line consists of cut circular involute vortex teeth; the fixed vortex plate correction molded line consists of separated adjacent circular involute vortex teeth; the movable (fixed) vortex plate correction molded line forms first-grade compression on outer rings ofthe cut (separated) vortex teeth, and forms second-grade compression on inner rings; the vortex tooth bottoms of large arc EF of the first-grade compression part to the inner rings are higher than the tooth bottoms to the outer rings; and the vortex tooth tops of small arcs E1F1 to the outer rings are higher than the tooth tops to the inner rings. The vortex mechanical single-disc double-stage molded line structure design method solves the problem of high exhaust temperature under high pressure ratio in single-grade compression, realizes double-stage compression and middle cooling of single pair of vortex plates, effectively reduces the exhaust temperatures of the vortex plates, reduces the power consumption, prolongs the machine service life, improves the reliability, and provides theoretical basis to practical engineering application.

Description

technical field [0001] The invention belongs to the field of mechanical design and processing, and in particular relates to a method for designing a single-disc and two-stage structure of a scroll machine. Background technique [0002] During the operation of the scroll machinery, the high exhaust temperature will cause the scroll to expand due to heat, which will affect the service life and reliability of the machine. At present, most of the scrolls on the market use air-cooling or water-cooling to dissipate heat to improve machine performance; in order to obtain high-pressure gas, designers often change scroll machinery from single-stage compression to two-stage compression and intermediate compression. Cooling to reduce exhaust temperature and power consumption, but currently there is no scroll machine on the market that realizes a two-stage compression structure on a single pair of scrolls. Contents of the invention [0003] In order to solve the above-mentioned techn...
