针对气缸缸盖开裂导致隔膜压缩机运行安全问题,结合高温、高压工况下热应力因素的影响,对隔膜压缩机气缸缸盖的结构进行有限元分析研究,得到了缸盖开裂处受力状况与开裂处结构关联关系。考虑高温、高压工况下热应力因素的影响,应用有限元方法分析了隔膜压缩机气缸缸盖在工作工况下的受力情况,基于实验与分析结果对缸盖材料、结构进行了优化设计。仿真结果表明,经对缸盖的材料、结构的全面优化,在承受高压工况下隔膜压缩机的可靠性明显提高。

Aiming at the safety problem of the diaphragm compressor caused by the cracking of the cylinder head,this paper conducts a finite element analysis and research on the structure of the cylinder head of the diaphragm compressor.The relationship between the stress state at the cracked part of the cylinder head and the structure of the cracked part is obtained.Considering the influence of thermal stress factors under high temperature and high pressure conditions,the finite element method is used to analyze the stress of the diaphragm compressor cylinder head under working conditions.Based on the experimental and analysis results,the material and structure of the cylinder head are optimized.The simulation results show that the reliability of the diaphragm compressor under high pressure conditions is significantly improved after the overall optimization of the material and structure of the cylinder head.
