变频调速技术及其在矿用对旋轴流式通风机上的应用

摘要

在分析变频调速技术原理的基础上,以某矿井为实现节能减排的目的而选用的型号为FBCDZ-6-№18的对旋轴流式通风机为例,具体分析在旋轴流式通风机上运用变频调速技术所产生的节能效果.对通风机实测的变频数据显示:为该通风机配备2×110 kW、380 V 的电动机后,Ⅰ级、Ⅱ级叶轮的变化有明显的差异,节能的幅度在12％～51％左右.%On the basis of analyzing the technical principle of frequency conversion speed regulation, taking the counter-rotating axial flow fan of FBCDZ- 6- F18 selected for the purpose of energy saving and emission reduction in a mine as an example, This paper analyzes the energy saving effect of variable frequency speed regulation technology in rotary axial flow fan. The measured frequency conversion data of the ventilator show that after the fan is equipped with 2 × 110kW / 380V motor, the variation of the first and second grade impellers is obviously different, and the range of energy saving is about 12. 1％.
