通风机并联工作的风压特性曲线与工况分析

Parallel Operation of Wind Pressure of Ventilator Characteristic Curve and Working Condition Analysis

在原有的一台通风机的风量不能满足正常生产需要时,可以将两台或者两台以上的通风机并联工作^([1])。文章通过分析两种不同的分机并联方式的风压及特性曲线为矿井并联风路的选择提供参考。

With the expansion of production scale, the roadway drivagemining face and the rise of some old mines, in the original a fan air volume can not meet the needs of the normal production, can he two or more than two fan parallel work [1]. But only in alignment with parallel operation of wind pressure, the characteristics of and industrial and mining point in order to maximize the efficiency of the fan. This paper analyses the two different kinds of wind pressure and the characteristic of the extension in parallel, get Characteristics of the two, to provide the reference for the mine air parallel road choice.
