摘　　要：隔膜压缩机因良好的密封性能而被广泛用于加氢站,但其以膜片往复压缩气体的特点使它不适合加氢站频繁启停的工况。基于隔膜压缩机的工作原理,提出一种以液压油直接驱动活塞压缩气体的新结构,并对液压系统进行设计,以适应加氢站频繁启停工况;为提高液驱系统性能,对液驱系统中活塞进行力学仿真与优化。结果表明:与传统隔膜压缩机的同种机型对比,液压驱动隔膜压缩机占地面积为原机型的四分之一,解决了传统机型因频繁启停造成隔膜片寿命降低的问题。该结构设计为解决加氢站隔膜压缩机技术问题提供了理论价值。Diaphragm compressors are widely used in hydrogen refueling stations because of their good sealing performance,but their characteristics of diaphragm reciprocating compressed gas make them not suitable for frequent start and stop conditions of hydrogen refueling stations.Based on the working principle of diaphragm compressor,this paper proposes a new structure of direct drive piston compression gas with hydraulic oil,and designs the hydraulic system to adapt to the frequent start-stop conditions of hydrogen refueling stations.In order to improve the performance of the liquid flooding system,the mechanical simulation and optimization of pistons in the liquid flooding system were carried out.The results show that compared with the same model of the traditional diaphragm compressor,the hydraulically driven diaphragm compressor occupies a quarter of the original model,which solves the problem of reduced diaphragm life caused by frequent start and stop of the traditional model.The structural design provides theoretical value for solving the technical problems of diaphragm compressors in hydrogen refueling stations.
