Description

Technical Field

[0001] This utility model relates to the field of compressor piston remanufacturing technology, and in particular to a remanufacturing device for a large natural gas compressor piston assembly. Background Technology

[0002] With rapid industrial development, especially in the use of critical equipment such as natural gas compressors, piston assemblies, as important key components, are subjected to harsh environments such as high temperature, high pressure, wear, and corrosion for extended periods. This can easily lead to surface wear, carbon buildup, and rust, thus affecting the operating efficiency and service life of the equipment. In daily use, once the piston assembly of a natural gas compressor is damaged or aged, it must be repaired or replaced.

[0003] When faced with the need for remanufacturing piston assemblies, traditional spraying processes cannot ensure that wear-resistant molten metal is sprayed evenly and fully onto the piston surface. In particular, when spraying on piston surfaces with complex shapes, uneven coatings are easily produced, which cannot effectively improve the wear resistance and corrosion resistance of the piston surface. Moreover, existing cleaning equipment mostly uses simple water rinsing or manual cleaning, which cannot thoroughly remove oil, carbon deposits, rust and other impurities from the piston surface. As a result, the remanufactured piston assembly may still have internal or external contaminants, affecting its performance and lifespan. Utility Model Content
