离心风机与离心风机串联特性的试验研究

Experimental Study on the Performance of the Centrifugal Fan and the Centrifugal Fan in Series

在改变阻力层和风机转速的条件下,进行两个离心风机一吸一排串联实验,分析了流量与效率之间的关系,阻力层同效率之间的关系。对串联风机系统中阻力层及风机转速的参数选择具有一定的参考价值。

Under the condition of changing resistance and rotating speed, experiments of the ventilating characteristic of fans in series were made, the relationships among flux, efficiency and resistance were analyzed. It has practical value to the parameter selections of resistance and rotating speed in series.
