摘要(Abstract):

高压压缩机高压缸阀座底部截面过度处裂纹,通过有限元应力分析,发现压缩机高压气缸阀腔底径厚度不够,阀腔底径偏小,由此对阀腔底径厚度和阀腔底径进行了设计改进,改进后的气缸未再开裂。
High-pressure cylinder occurred Cracks,the Cracks start at the bottom of valve chambers transition section.From finite element stress calculation,the bottom thickness of valve chamber in the high-pressure broken cylinder is not enough,and the passage section of valve chamber is also not enough,so the design of valve chamber is improved,after improvement,Cracks to high-pressure cylinder have not occurred anymore.
