在往复式循环压缩机中,运动件的抗擦伤性能和耐磨性能的好坏,是影响整个机组能否正常工作、经济性和寿命的因素,对于无油润滑的运动件来说,尤其如此。近几年来,以厂所结合的方式,对东方红炼油厂使用的无锡压缩机厂生产的D6.5—4.6/70-90往复式循环压缩机活塞杆表面,进行了采用等离子体喷涂工艺以提高表面抗擦伤性和耐磨性的试验。喷涂 In the reciprocating cycle compressor, the moving parts of the anti-abrasion performance and wear resistance is good or bad, affect the entire unit can work, economy and life of the factors, for non-oil-lubricated moving parts, especially in this way. In recent years, the way to combine the factory, the East Red Refinery Wuxi compressor factory production D6.5-4.6 / 70-90 reciprocating compressor piston rod surface, the use of plasma spraying process to Test to improve surface abrasion and abrasion resistance.
