How to install tunnel jet fan

         Today I will introduce the installation method of tunnel jet fan ventilation pipe.


       1. The air duct is connected with the air duct with a pull lock, and the air duct is fixed on the galvanized steel wire rope according to the buckle (buckle) on the air duct; There is a structural steel rope and a buckle on the air duct every 3.0m, leveling the air duct and reducing the friction resistance of romantic charm.


       2. Galvanized wire rope is fixed to the authentic vault or side wall with expansion screws and secured with 12 expansion screws. The anchorage length is not less than 7cm, and the spacing is 3.0m. The duct of tunnel jet fan should be vertical, tight and stable to avoid folding, increase part of friction resistance and avoid dead bend connected with horizontal hole.


       3. The installation height of the air duct can not block the measuring horizon of the monitor, ensure the static height considered in the hole, avoid the past automobile and mechanical equipment scratching the air duct, endangering the construction. Tunnel jet fan.


       4. The unavoidable distance between the air duct inlet and the working face is related to the large section. Air volume is big. Large diameter air duct should be controlled within 20~30m.


       5. Related to the forced natural ventilation, the tunnel jet fan is usually installed on a support frame with a spacing of more than 10m at the edge of the holes, and has a certain static height. Dirt shall not be deposited within 5m before and after authentic centrifugal fans. Iron grille and safety device should be set up in the inlet of authentic centrifugal fan, and problems should be actively closed.


       6. When the air duct is introduced into the second lining car, it shall not cross the frame from the middle. The load-bearing beam platform of the second lining car must be flat left and right, and do a good job of safety protection to avoid damage to the duct.
