我厂两台2Z 3/8-1无油润滑空气压缩机(柳州第二空气压缩机厂制造),在运行中经常有润滑油液进入气缸,所以每个月(有时只有两周)就需停机更换刮油环,从而影响生产。为此,我们对刮油环的结构进行了局部改进,用一只耐油橡胶环(分瓣式)代替一只铜环,且将橡胶环装在最下面。其外圆用聚四氟乙烯环和弹簧系紧,内径具有30斜口,组装时向下,使之紧贴于活塞杆外圆,以便能顺利将活塞杆外圆上的油刮下,改进前后
Two 2Z 3 / 8-1 oil-free air compressors (made by Liuzhou No.2 Air Compressor Factory) are used in our factory. During operation, lubricating oil often enters the cylinder, so every month (sometimes only two weeks) Stop replacing the scraper ring, thus affecting the production. To this end, we made a partial improvement on the structure of the scraper ring, with a oil-resistant rubber ring (split-type) instead of a copper ring, and the rubber ring at the bottom. The outer ring with PTFE ring and spring fasteners, the inner diameter of 30 inclined mouth, the assembly down, so close to the piston rod outer circle, so that the piston rod can be smoothly scraped the oil on the outer circle to improve Before and after
