反压环境舱的设计及在雾化实验中的应用

介绍了反压环境舱的设计思路、结构特点及其在喷嘴特性研究过程中的应用.环境舱包括:舱盖提升机构、舱体移动机构、喷嘴调节装置、气幕隔离装置、视镜和散光装置.所设计的环境舱视镜通光直径为110mm,环境压力高达6.0MPa.实验结果表明,反压环境舱能配合高速动态分析系统完成高压环境下流量和雾化性能实验.

Design and application of pressure environmental chamber in atomization test

The structure characteristics and application of pressure environmental chamber for injector performance test were introduced. The environmental chamber consists of a chamber cover, an elevator device, a chamber body shifting device, an injector adjustment device, gas-film separat- ing devices, windows and an astigmatism device. The transparent diameter of environmental chamber is 110mm, and the pressure is as high as 6.0MPa. The results indicate that the high pressure atomization performance tests can be accomplished with pressure environmental chamber combined with high speed dynamic analysis system.
