【摘要】 本文理论推导了可调静叶各叶调节幅度从前至后逐渐减小的规律,指出最末排静叶调节幅度很小,可以设计成固定不可调的。对于固定的最末排静叶的安装角,采用小开度对应的小安装角会使风机流量堵塞,所以不选取小安装角。通过对比研究最末排静叶安装角分别为中间开度对应的安装角和大开度对应的安装角的两机组,本文最终得出结论:采用中间开度对应的最末排静叶安装角,能使风机实现流量调节,并能实现较高的压比。更多还原

【Abstract】 This article theoretically proved that the adjustment angle of the adjustable stator blade decreases from front to back,and pointed out that the end stator blade s adjustment angle is so small that they can be designed as fixed.As to the end fixed stator blades installation angle,small installation angle which makes the blower jam can t be adopted,while contrastive research indicated that by adopting the installation angle which fits the air blower best when it produces middle air mass flow,the blower achieves higher compression ratio and adjustable air mass flow.更多还原
