柱塞火焰喷涂工艺与设备

粉末火焰喷涂是一种基本的热喷涂方法 ,它利用了气体燃烧火焰为高温热源的特点 ,将耐蚀、耐磨性能均较强的自熔性合金粉末喷向金属工件 ,在工件表面形成一定厚度的保护层 ,以提高工件耐腐蚀、耐磨损性能。在抽油泵柱塞表面实施喷涂工艺 ,可显著地提高其使用寿命。其工艺流程为表面预处理、预热、预喷粉、喷粉、重熔、热校直等 ,主要设备有表面清理设备、喷涂机床、喷涂枪、重熔枪、热校直机等。

Technology and equipment for flame spraying plunger

Powder flame spraying is one of basic hot spraying technology.Self melding nickel based alloy powder that is highly wear resistant and corrosion resistant is sprayed onto surface of metal workpiece by spray gun to form a protecting layer.It can improve resistance to wear and corrosion of workpiece.The flame hot spraying can outstandingly increases service life of plunger in sucker rod pump.Its essential process includes surface pretreatment,preheating,pre dusting,dusting,re melting and heat straightening and major equipment consists of surface cleaning equipment,spaying machine tool,spraying gun,re melting torch and heat straightening machinery,etc..
