以对心曲柄滑块机构模型为基础,分析了影响活塞式压缩机构尺寸大小及影响活塞磨损的主要因素,并设计了对称平衡型压缩机;通过实验研究,得到了压缩机高转速下自润滑活塞材料配方,并制备了自润滑活塞;通过性能测试,设计压缩机满足车载制氧要求.
Based on the model of centric slider-crank mechanism, main impact factors of the piston compressor size and the piston abrasion were analyzed. Then symmetrically balanced c, ompressor was designed. The formulation of self- lubricating materials was gained through experimental research and high speed piston was prepared according to it. Testing results showed that the designed compressor meet the requirements of oxygen generating for vehicles.
