- product introduction:The Yatai DTF (R) series reversible axial flow fans for subway tunnels have significant characteristics such as high efficiency and wide efficiency range, low noise, consistent forward and reverse performance, anti surge, compact structure, and high temperature resistance. This series of fans has 13 specifications ranging from 12.5 to 28 #, with an air volume of 30000 to 600000 meters 3/ h. Pressure of 200-2000Pa. The fan is composed of a casing, impeller, guide vanes, support, fairing, built-in motor, power junction box, etc. There are three forms of fixed, static, and dynamic adjustment on the blade angle of the fan, which can meet the needs of use under multiple working conditions; Divide the functions of air supply, exhaust, and fire smoke exhaust in terms of usage. Large scale subway axial flow fans, along with their accompanying silencers, combined air valves, etc., are the main components of subway ventilation systems and are widely used in environmental control systems for large construction projects such as subways, tunnels, mines, and water conservancy dams.
Due to the limited building space inside subway stations and carriages, during peak periods of vehicle traffic, the concentration of passengers can easily lead to air turbidity and increased exhaust gas. At the same time, the heat generated by subway vehicle operation is concentrated, affecting the air quality inside the stations and carriages. By introducing fresh air through this fan, harmful gases are eliminated, thereby avoiding vehicle overheating and maintaining air circulation inside the stations and carriages to ensure good air quality inside the carriages, Ensure the comfort of passengers and the safety and stability of subway operation.
The axial flow fan of Yatai Metro Tunnel has obtained the national first level energy efficiency certification for wind turbines.
