SDS Underground Tunnel Ventilation Jet Turbine Fans

SDS Underground Tunnel Ventilation Jet Turbine Fans

  • Description
  • Inquiry

The need for tunnel ventilation is critical for the life and safety of any person utilizing the metro, rail or road tunnels throughout the world. Typically the equipment is used for smoke extraction or control for the time it takes people to evacuate the tunnel under emergency conditions. They are also utilized to control exhaust fumes and to provide standard ventilation when required.

Our company is the earliest manufacturer of jet fan for tunnel, has many years of production experience and a number of project performance, has accumulated a variety of different types of jet fan design and manufacturing experience, and according to the test of jet fans and the use of working conditions, established the jet fan technology database, so you can continue to improve the jet blower turbine blade manifold and size. The key parts of my company production of jet fan have been achieved in mold making. To determine the role of noise rectifier by forming hydraulic press 315 tons, to ensure that the wind has the best streamline structure. The key parts of the fan impeller is made of ZLG114 aluminum alloy by low pressure casting machine, J453A die-casting molding, molding after annealing and aging treatment and tensile test, after testing y ray flaw detection machine detection, through the high precision dynamic balancing machine balancing check, ensure that the fan can be long-term reliable operation.

1, a wide range of performance, more choice.
2, low energy consumption and high thrust.
3, special design. Impeller
4, a finely balanced, the fan running smoothly.
5, special motor, the fan can be a long-term reliable operation, more than 20000 hours of operation.
6, T type bidirectional ventilation equipment, and wind speed are equal, only need to change the motor rotation, can realize the anti-wind.
7, can be equipped with double speed motor when natural ventilation is strong, low-speed operation can reduce the operation cost.
8, easy to maintain.
