作为铁路、公路隧道与矿井通风用的消音对旋式轴流通风机具有下列特点:即在较小体积下能达到大流量、高压力和高效率。与普通风机相比,所需风机数量和电能消耗大为节省,并可任意移动和设置于任何较小的空间。研制这种风机虽非轻而易举,但也不存在难以逾越的障碍,因而完全不必进口而可以靠国内设计生产。本文就对旋风机设计中的主要问题作一些分析与探讨。 As a railway, road tunnel and mine ventilation with silencer on the rotary axial fan has the following characteristics: In a smaller volume can achieve high flow, high pressure and high efficiency. Compared with the normal fan, the required number of fans and power consumption is greatly saving, and can be arbitrarily moved and set in any smaller space. The development of this fan is not easy, but there are no insurmountable obstacles, so do not have to import and can rely on domestic design and production. This article on the cyclone design of the main problems for some analysis and discussion.
