摘要
为验证出口蜗壳调节方式能否用于后弯型离心风机，对４－７２系列Ｎｏ．６双吸风机进行了实验研究，得出了蜗壳调节风机相对于原型风机的无因次全压、功率、效率与流量的关系，说明蜗壳调节不能使风机曲线扁平化，亦无节能效果，故不适用于４－７２系列后弯型离心风机。
To determine applicability of the adjustment to backward
bladed fans, presents the nondimensional total pressure, power and efficiency based on those of
the prototype fan of 4-72 series, measured in an experiment, which shows that this regulating
method has no effect of flatting the performance curve and reducing energy consumption, therefore
is not applicable to backward bladed fans.
