聚四氟乙烯塑料活塞环在锻锤上的应用,已引起越来越多的工厂的注意。我厂自8O年代初就开始了试用。实践证朗:使用效果良好,比钢制活塞环效果更佳,是值得推广的。使用聚四氟乙烯塑料活塞环可以大大地减少汽缸套的磨损和拉伤,从而显著地增加汽缸 Polytetrafluoroethylene plastic piston ring on the hammer on the application, has attracted more and more factories attention. I plant since the early 80s began a trial. Practice Long: the use of good results, better than steel piston rings, is worth promoting. The use of PTFE plastic piston rings can greatly reduce the cylinder liner wear and tear, thereby significantly increasing the cylinder
