空压机气缸无油润滑,是指采用耐磨减摩性能优异的填充聚四氟乙烯塑料活塞环代替原金属活塞环。从而实现无油润滑运转的一项新技术。空压机气缸实现无油润滑,不仅可省去注油所需的附属设备,且可改善工艺条件与生产环境,提高生产率,对节约能源也有重要意义,是值得大力推广应用的新技术。本文就着重介绍这一新技术及其在我局的应用。一、空压机气缸无油润滑的工作原理 1.密封原理(背压原理) 填充聚四氟乙烯活塞环(简称填充四氟环)与金属活塞环的密封原理是基本相同的。空压 Air compressor cylinder oil-free, refers to the use of wear-resistant antifriction padded PTFE plastic piston ring instead of the original metal piston ring. A new technology for oil-free operation is therefore achieved. Air compressor cylinder to achieve oil-free lubrication, not only eliminates the need for oiling ancillary equipment, and can improve the process conditions and production environment, increase productivity, energy conservation is also of great significance, is worthy of promotion and application of new technologies. This article focuses on introducing this new technology and its application in our office. First, the working principle of air compressor cylinder oil-free lubrication 1. Seal principle (back pressure principle) Filled polytetrafluoroethylene piston ring (PTFE ring) and the metal piston ring sealing principle is basically the same. Air pressure
