Usage
The TDJ series low-noise tunnel fan is a dynamic and tunable two-stage impeller counter-rotating. Two special impellers equipped with imported SKF Swedish bearings directly drive two opposite impellers.
The TDJ series low-noise tunnel axial flow fan is also movable and can be calibrated for single-pole impeller rotation.
A single-stage impeller is directly driven by a special motor equipped with imported SKF Swedish bearings.
Tunnel construction ventilators are widely used in railway tunnels, highway tunnel water conservancy construction projects, ventilation, ventilation equipment for mines, power stations and other underground construction projects.
As the tunneling depth increases, different fan performances are obtained by adjusting the blade mounting angle, and the flow pressure is gradually increased, thereby reducing the operating cost of the fan. The fan is allowed to run in reverse wind, but the impeller must be started after the impeller is completely stationary.
The conveying medium is air, the dust content is

DSSF series (two-speed) counter-rotating-type counter-rotating axial flow tunnel ventilator is mainly used in high-speed rail, expressway, railway, ...
