1 前言 填料是密封气缸和活塞杆间隙的元件,它可以阻止气体自气缸向机身内泄漏.在压缩机设计中,填料的设计是一个重要的环节,填料如果设计欠缺,制造精度达不到设计要求,将会使泄漏系数增大,从而对压缩机的性能产生不利的影响。下面是作者在实践中总结得出的一点经验,请同行内各位专家指教,文中提到的密封环是聚四氟乙烯材料的密封环,其它材料的密封环的工作原理雷同。
1 Introduction Filler is a component that seals the gap between the cylinder and piston rod and prevents gas from leaking from the cylinder to the fuselage. In the design of compressors, the design of the packing material is an important step. If the filler material is lack of design, the manufacturing precision can not reach The design requirements will increase the leakage coefficient, adversely affecting compressor performance. The following is the author in practice summed up a little experience, experts in the enlightenment counterparts, mentioned in the text of the seal ring is PTFE seal ring, the seal ring of other materials works the same.
