Self-lubricating type scroll plate and manufacturing method thereof

Abstract

The invention provides a self-lubricating type scroll plate and a manufacturing method thereof. The self-lubricating type scroll plate comprises a scroll plate body, wherein an oxidation film is arranged on the outer surface of the scroll plate body; a plurality of corrosion holes are formed in the oxidation film, and a self-lubricating coating is arranged on the outer surface of the oxidation film; and a ratio of the thickness of the oxidation film to the depth of an aperture is 1:1. The method comprises the steps that a metal material is machined into the scroll plate; the surface of the scroll plate is subjected to oxidation treatment to form an oxidation film; the outer surface of the scroll plate after the oxidation treatment is coated with a polymer coating; and finally, the scroll plate coated with the polymer is dried and cured to form a self-lubricating coating. According to the scroll plate and the manufacturing method, the scroll plate is subjected to oxidation treatment, and the oxidation film is coated with the polymer coating, so that a self-lubricating coating is formed, the self-lubricating property of the scroll plate is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of scroll disk manufacturing, in particular to a self-lubricating scroll disk and a manufacturing method thereof. Background technique [0002] In the fields of household air conditioners, automobile air conditioners, and some air supply systems, scroll machinery such as scroll compressors are widely used. The transmission part is mainly composed of scroll moving disk and scroll static disk. The static disk is made of lightweight aluminum alloy through precision machining, and the scroll compressor usually uses a certain amount of lubricating oil, which reduces the working efficiency of the compressor, and the operating conditions in many fields cannot provide a good friction pair for the dynamic and static scroll. Lubrication conditions, which make the lubrication effect of the scroll poor. At the same time, based on the friction and wear failure characteristics of a pair of friction pairs, the scroll is ea...
