一、经济效益: 我厂在对两台升压机,4台循环机的轴向密封和气缸润滑全部实现无油润滑的基础上,又经将近一年的努力,使8台2D型高压机全部实现了无油润滑。高压机气缸无油润滑的主要革新任务是:(1)设计填充聚四氟乙烯塑料活塞环(简称填充四氟或F—4):(2)设计高压 First, the economic benefits: I plant on the two booster, four-cycle machine axial seal and cylinder lubrication all achieved on the basis of oil-free lubrication, and after nearly a year of hard work, so that 8 sets of 2D high-pressure machine All achieved without oil lubrication. The main innovation tasks of high pressure cylinder without oil lubrication are as follows: (1) design of filled polytetrafluoroethylene plastic piston ring (referred to as filling PTFE or F-4): (2) design of high pressure
