【摘要】 本文叙述了一种新型后掠式离心压气机的设计、制造和试验,并与普通径疏式离心压气机作了对比:绝热效率可提高4%、有效流量范围在额定转数时扩大了11.4%、高效率区扩大42%。文中对喘振原理的解释及喘振工况的预测可供研究具有无叶扩压器的离心压气机时参考。更多还原

【Abstract】 In this paper, the designing principle, manufacturing technology and testing result of a backswept bladed compressor impeller with controlled exit are described and analysed. As compared with the ordinary radial bladed compressor impeller, its adiabatic efficiency increases by 4%, its effective flow range at rated speed widens by 11.4% and its max. efficiency zone enlarges by 42%.The principle and boundary of surge of centrifugal compressor with certain vaneless diffuser are interpreted and predicted, and confirmed by this experiment as well.更多还原
