What is the thrust calculation of tunnel fan related to

    Tunnel fans are all advanced technology, which has a good guarantee for its quality, especially starting from the shell, can treasure its strength. Most of the tunnel conditions are relatively familiar to us. In order to have good ventilation, the casing of the tunnel fan is made of anticorrosive materials. This is the first line of Defense, which can protect the fan from corrosion Corrosion for a long time. The ventilation system of tunnel fan is the most important, and the calculation of its thrust is also very important for ventilation. What is the thrust calculation of tunnel fan related to? Let's take a look Zibo tunnel fan manufacturer Give us an introduction.

 Tunnel fan

[what is related to the thrust calculation of tunnel fan]


(1) loss of exit entrance barrier, conflict coefficient of tunnel name and facilities, vehicle conflict coefficient, vehicle activity or wind effect under the most advantageous environment, and the response of wind speed outside the tunnel to the exit and entrance under the most advantageous environment. The thrust, measurement, pressure and time required in case of fire in tunnel terrain, slope and elevation.


The thrust of falling fan is the dynamic change between the outlet and the inlet of the fan, i.e. the thrust of the fan is n = C * mass flow * cyclone progress, Newton = static thrust of the fan, C = correction coefficient, mass flow = atmosphere density * volume flow. What is the thrust calculation basis of tunnel fan ventilation system? The results show that the effective thrust of the falling fan is n = invalid thrust of the fan Newton v = wind speed M / s in the tunnel v = falling progress M / S C = collision coefficient in the tunnel C = the loss of flow direction in parallel arrangement of the same group, such as 100 times of continuous fan diameter between fan units, so that the falling progress does not reflect the operation environment of the position along the gas rotation.


The most fundamental purpose of the emergence of tunnel fan ventilation system is to maintain the ventilation quality in the tunnel, so that the construction workers can have a safe working environment. For this purpose, the use of tunnel fan is not only one, but also multiple parallel fans, each with its own division of labor.
