Working Principle

Tunnel fan is an indispensable part of many ventilation systems, and it can also be used as a dust removal machine fan when it is used. It is also an indispensable mechanical equipment in many tunnels or construction. The complete operation of the equipment also depends on its working principle.

When the impeller of the opening equipment rotates at a high speed, the air in each part of the impeller will also be driven to rotate together, and at this time the air at the impeller position will be thrown to the impeller because of the centrifugal force. The edge, which will form a vacuum position at the position of the impeller, then the external air will flow in continuously under the action of the pressure difference, then it will be added to the position of the impeller so that the fan has the ability to suck into the air.

Function

1. Tunnel fan is a common heat dissipation fan in tunnel construction. The main purpose of the high-power industrial exhaust machine is to make the gas flow in the tunnel construction, exhaust gas, and inject fresh air to dilute the exhaust gas in the tunnel construction and reduce damage.

2. If a fire accident occurs in the tunnel fan, the heat dissipation fan can be opened according to the opposite side of the fire point to reduce indoor ventilation, slowly increase the fire point, and have enough time to evacuate.

3. Tunnel fans are mainly used to discharge tunnel construction. Due to explosions, gas turbine applications, and the release of harmful substances from the geological structure of foundation pit excavation, it is an excellent natural environment for tunnel construction, maintaining the physical and mental health of staff, ensuring everything is normal, and improving Work efficiency is a key standard to ensure the quality of engineering construction.
