摘要
将 4L - 2 0 / 8型空气压缩机由有油润滑结构改造成无油润滑结构 ,通过改变活塞结构尺寸和采用填充聚四氟乙烯活塞环及导向环 ,在压缩机工艺指标不变的情况下 。
Through changing the piston rings and the guide rings with PIFE filler, the oil lubricated 4L-20/8 type air compressor is turned into an oil less compressor gaining the excellent properties which can not be reached by the old one under the unchanged parameters.
