摘　　要：为了解决排气温度过高使隔膜压缩机抗氢脆性能降低从而导致寿命降低的问题,提出了一种新型冷却管道的隔膜压缩机结构。以降低隔膜压缩机气缸温度为目标,在高温、高压的工况下,对改进后的气缸结构进行流体力学分析研究,得到温度场云图。仿真结果表明:优化后的隔膜压缩机气缸结构在同样工况下的温度明显降低,可知压缩机气缸的氢脆问题得到缓解,该结构有效提高了隔膜压缩机的使用寿命。In order to solve the problem that the exhaust temperature is too high,the anti-hydrogen embrittlement performance of diaphragm compressor is reduced,and the life is reduced,a new diaphragm compressor structure of the cooling pipeline is proposed.With the goal of reducing the temperature of the diaphragm compressor cylinder,under the working conditions of high temperature and high pressure,the improved cylinder structure was analyzed and studied,and the temperature field cloud map was obtained.The simulation results show that the temperature of the optimized diaphragm compressor cylinder structure is significantly reduced under the same working conditions,and it can be seen that the hydrogen embrittlement problem of compressor cylinder is alleviated,and the structure effectively improves the service life of diaphragm compressor.
