4-72系列风机出口蜗壳调节方式的研究 【英文篇名】 Experiment of adjusting outlet volute of centrifugal fans 【作者中文名】 吴钟大; 毛建素; 何立岩; 张桂娟; 【作者英文名】 Wu Zhongda ★; Mao Jiansu; He; Liyan and Zhang Guijuan; 【作者单位】 沈阳东宇企业集团; 沈阳东宇空调净化技术研究所; 【文献出处】 暖通空调, HV 蜗壳调节; 节能; 【英文关键词】 fan; volute adjusting; energy saving; 【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。 【英文摘要】 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.
