我厂的无油润滑是从1979年正式在L3.3压缩机上试验使用的,经过近三年多的不断模索,取得了初步成功,现每台L机注油器已从11头减为4头,使用中操作稳定,检修方便,气密性良好,完全能满足生产的要求。压缩机实现无油润滑,主要需要解决填料密封、气缸活塞环、支承环等问题,其中关键 I plant from the oil-free lubrication from the official test on the L3.3 compressor used in the past three years after more than a constant model, and achieved initial success, now each L machine lubricator has been reduced from 11 to 4 , The use of stable operation, easy maintenance, gas tightness, fully able to meet the production requirements. Compressor to achieve oil-free lubrication, the main need to solve the packing seal, cylinder piston rings, support rings and other issues, of which the key
