Tunnel jet fan

SDS series ejector ventilator is a product developed by our company using the existing domestic academic mechanism research results and foreign advanced technology. The engineering technology center of our company is committed to the continuous research and development of theoretical technology and technological innovation. Also at home and abroad to communicate with the same company and fully research subway, highway, railway tunnel engineering, water conservancy dam engineering system, and consulting for subway tunnel design institute, design institute and the tunnel installation company experts, mastered the use requirement of the fan, accumulated the product technology, quality requirements and conditions of use experience. So that the fan has efficiency and A sound level is better than the conventional ordinary axial flow fan, its fan varieties and specifications selection, optimization of all kinds of engineering system matching in the domestic peer leading level. SDS series jet fan specifications from φ630mm~φ1600mm, divided into unidirectional axial flow fan and reversible (bidirectional) axial flow fan two categories, the maximum thrust of 3500N, for any load and working conditions can choose high efficiency, low noise fan. SDS jetting ventilator series adopts advanced technology achieves a good quality assurance, fan shell adopts the imported special machine spinning flanging forming, impeller section inside the gold processing, not only ensure casing coaxial degree and intensity, and ensure the blade radial clearance, appearance by the hot dip galvanized processing, good appearance and excellent anticorrosion performance, The fan blade and wheel hub are processed into die casting mold cavity by Toshiba's CNC boring and milling machining center, and aluminum alloy is high in high pressure casting and low pressure casting machines respectively. (low) die casting, the actual use of highway tunnel, railway tunnel, water conservancy dam project users proved that the fan performance indicators and corrosion resistance, reliability, economy and other technical, quality requirements and economic indicators can fully adapt to the use of all kinds of tunnels, subway.
