空气锤锤杆由于润滑条件不良 ,经常处于干摩擦状态下工作 ,且工作气缸及其导程受锤杆活塞上下运动的摩擦、冲击和较高温度的影响 ,使铁粉末积聚成坚硬的积屑瘤。这些瘤像刀子一样划伤锤杆 ,当锤杆表面划伤很深并且气缸导程于锤杆配合间隙又超过国家标准时 ,须对锤杆和导程进行? Due to the poor lubrication conditions, the air hammer hammer often works in a dry friction condition. The working cylinder and its lead are affected by the friction, impact and higher temperature of the hammer piston up and down to accumulate the iron powder into a solid BUE. These tumors scratch the hammer like a knife. When the surface of the hammer is deeply scratched and the cylinder guide passes the national standard with the hammer, the hammer and lead should be made.
