根据用途不同轴流风机又可分为普通玻璃钢轴流风机和防爆玻璃钢轴流风机，那现在咱们一起去看下防爆玻璃钢轴流风机，它都有哪个优势：

According to the use of different axial fan can be divided into ordinary FRP axial fan and explosion-proof FRP axial fan, and now we go to see the explosion proof FRP shaft fan, it has which advantage:

1、叶轮的叶片安装角的可调整，可根据生产的要求来调整叶片角度。无论在任何环境下都可以稳定运转。

1. The blade installation angle of the impeller can be adjusted, and the blade angle can be adjusted according to the production requirements. It can operate steadily in any environment.

2、该风机在电机外面安装全封闭型并具有一定耐压强度的密闭散热罩及气压平衡管，使电机始终处于无瓦斯空气之中运行，达到了煤矿有关防爆规程的要求。

2. The fan is installed outside the motor and has a closed and pressure - resistant closed heat shield and air pressure balance tube, so that the motor is always in the gas - free air and meets the requirements of the coal mine related to the explosion protection regulations.

3、采用电动机与叶轮直联的风机最简结构，改变了当前煤矿抽出式轴流通风及全部采用皮带传动或长轴传动的复杂结构，利于运行和维修。

3. The simplest structure of the fan with the direct connection of the motor and the impeller has changed the current coal mine pumped axial flow ventilation and the complex structure of all the belt drive or long shaft transmission, which is beneficial to the operation and maintenance.

4、该系列风机为单级工作轮结构，风机与扩散其中间设置后导叶，以提高静压效率。

4, the series of fans is a single stage working wheel structure, fan and diffuser in the middle of the rear guide vane, in order to improve the static pressure efficiency.

5、风机可反转反风，其反风量可达正风量的65%～85%，不必另设反风道，具有节约基建投资和反风速度快的优点。

5, the fan can reverse the reverse wind, and its reverse air volume can reach 65% to 85% of the positive air volume. It does not need to set up another anti air channel. It has the advantages of saving capital investment and fast wind speed.
