采用填充聚四氟乙烯对往复活塞式 2D压缩机在不改变原机结构的基础上进行了气缸无油润滑改造。通过:①减少活塞环切口的流通截面面积和间隙高度;②减薄活塞环径向厚度,适当增加活塞环的轴向高度;③相应减少环数;④减少密
Filling Teflon reciprocating piston 2D compressor without changing the original structure of the cylinder on the basis of the oil-free lubrication. By: ① reduce the flow cross-sectional area of the piston ring and clearance height; ② reduce the radial thickness of the piston ring, an appropriate increase in the axial height of the piston ring; ③ reduce the number of rings; ④ reduce the close
