Problems solved by technology

[0003] At present, the method of spraying paint is usually used to form a metal material layer on the casing of the compressor as its anti-corrosion coating, however, the metal material layer formed in this way usually has poor adhesion, and the The denseness of the formed metal material layer is poor, so it cannot meet the anti-corrosion requirements in the marine environment

Embodiment Construction

[0034] The core idea of ​​the present invention is to provide a method for forming an anti-corrosion coating of a compressor, including: performing surface treatment on the shell of the compressor; performing a fluxing process on the shell of the compressor to form a fluxing coating; The outer shell of the machine is immersed in the molten anti-corrosion paint to form an anti-corrosion coating.

[0035] In the method for forming the anti-corrosion coating of the compressor provided by the present invention, the shell of the compressor is immersed in the molten anti-corrosion coating to form the anti-corrosion coating on the surface. That is, by adopting the method of hot dipping, an anti-corrosion coating with a certain thickness and good compactness can be formed on the shell of the compressor, so as to overcome the problem of the compressor being eroded during long-term use and prolong the service life of the compressor. life. Moreover, in the method provided by the present...

Abstract

The invention provides a method for forming an anticorrosive coating of a compressor. The method includes the steps that a shell of the compressor is subjected to surface treatment; the shell of the compressor is subjected to a plating-assistant technology, so that a plating-assistant coating is formed; and the shell of the compressor is immersed into a molten anticorrosive coating so as to form the anticorrosive coating. Namely, the anticorrosive coating is formed on the shell of the compressor in a hot-dipping mode, the advantages of being high in efficiency, low in cost and good in coatingquality are achieved, and therefore the corrosion resistance of the anticorrosive coating can be improved obviously, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to a compressor, in particular to a method for forming an anti-corrosion coating of the compressor. Background technique [0002] Compressor casings are usually stamped from hot-rolled or cold-rolled mild steel, or constructed of gray cast iron. Therefore, it is usually necessary to form an anti-corrosion coating on the casing of the compressor for protection, otherwise the compressor will be highly susceptible to corrosion. Especially in the marine atmospheric environment, the compressor is more susceptible to corrosion, this is because the marine environment is a complex corrosive environment, seawater itself is a strong corrosive medium, and at the same time, waves and tides will continue to Shock to the compressor, which either directly or indirectly accelerates the corrosion process. [0003] At present, the method of spraying paint is usually used to form a metal material layer on the casing of the compressor as its anti-c...
