The typical elastomeric coating consists essentially of a polyurethane elastomeric coating, an acrylic elastomeric coating, and a silicone elastomeric coating, in this embodiment the first elastomeric coating comprises a rubber coating. Because the working condition is worse in the working process of the compressor, the rubber coating has the advantages of strong wear resistance, chemical corrosion resistance, low construction environment requirement, low cost and the like, and the rubber coating can adapt to deformation and pressure to a certain extent due to the elasticity of rubber, so that the valve plate 21 and the cylinder head 1 are better protected. Finally, the adhesive force of the rubber coating base material is strong, and the rubber coating base material is not easy to fall off, so that the rubber coating can maintain stability when the compressor works to shake.
In this example, the thickness of the rubber coating is d, wherein 0.05 mm.ltoreq.d.ltoreq.0.1 mm.

In this embodiment, the second elastic coating layer also includes a rubber coating layer, and the thickness of the rubber coating layer is also set between 0.05mm and 0.1 mm. Preferably, the thickness of the rubber coating is 0.07mm, and when the rubber coating is provided too thick, it affects the toughness and elasticity of the coating, making it more fragile and brittle. In addition, excessively thick rubber coatings may cause bubbles or blisters that affect the appearance and service life of the coating. And when the rubber coating is too thin, it may cause deterioration in abrasion resistance, corrosion resistance and adhesion of the coating. Meanwhile, an excessively thin coating may not cover defects or flaws on the surface of the substrate, affecting the overall quality and use of the coating. Thus, a suitable coating thickness may be selected according to the actual situation to ensure the performance and quality of the coating.
The utility model also provides a heat exchange system which can be arranged in an air conditioner or a refrigerator, the heat exchange system comprises the compressor structure 100, a compressor, a crankcase, a heat exchanger and the like, and the specific structure of the compressor structure 100 refers to the embodiment, and the compressor structure 100 of the heat exchange system adopts all the technical schemes of all the embodiments, so that the heat exchange system has at least all the beneficial effects brought by the technical schemes of the embodiment and is not repeated herein.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
