对活塞式无油润滑压缩机进行研究的主要任务是解决活塞和活塞杆的密封性能和使用寿命问题。为此,我们从活塞密封的结构和材料两方面进行试验研究。一、材料筛选目前,无油润滑压缩机密封元件应用最广泛的材料是以无机物填充的聚四氟乙烯。众所周知,影响填充聚四氟乙烯性能的因素是复杂的。比如,基体材料状况(包括分子量、粒度等),填充剂的种类、粒度、性能、含量,成型工艺等,任何一种因素的改变都将引起填充
The main task of piston-based oil-free compressor research is to solve the sealing performance and service life of piston and piston rod. To this end, we from the piston seal structure and materials for both experimental study. First, the material screening At present, non-oil-lubricated compressor sealing element is the most widely used material is polytetrafluoroethylene filled with inorganic matter. As we all know, the factors that affect the performance of filled PTFE are complex. For example, the substrate material (including molecular weight, particle size, etc.), filler type, particle size, performance, content, molding process, any change in any factor will cause filling
