Product introduction
1. Purpose:
SDS/SDF series tunnel jet fan is mainly used in highway, railway and other transportation tunnel longitudinal jet ventilation, the use of the high-speed jet stream of jet fan, drive along the stream direction of air inside the tunnel, so as to achieve ventilated take a breath, but a fire in the tunnel is smoke extraction can be achieved, jet fan transmission medium is air, The ambient temperature is -25ºC~50ºC, the content of dust and other solid impurities in the medium is not more than 150mg/m3, and there is no viscosity, no fiber material. In case of fire in the tunnel, it can run continuously for two hours under the high temperature of 280ºC.
2. The main features of the fan are:
Corrosion resistance, high temperature resistance, no fracture, no oxidation, fast wind speed at the exit, large air volume, low noise.
Smooth operation, simple maintenance, beautiful appearance, easy to use.
(3) Reversible jet fan can be two-way ventilation, when the reverse ventilation can reach and exceed 98% of the positive ventilation volume, to ensure that the tunnel is filled with fresh air.
SDS jet fan produced by our company can adopt high efficiency impeller developed by our company or imported fan impeller according to user needs. It can also be equipped with a two-speed motor according to user requirements, respectively for forced exhaust (smoke) or low-speed ventilation to maintain energy saving operation state.
Tunnel fan is specially designed for longitudinal ventilation and ventilation system of highway, railway tunnel and subway tunnel, and air ventilation equipment designed for smoke control in emergency situations. It can also be used for ventilation and ventilation in similar tunnel and auxiliary tunnel construction occasions. It is suitable for operation requirements of 3500 meters above sea level. In the -25~50ºC environment continuous work, fire, allowed in 250-280ºC in a short time not more than one hour.
Fan USES
SDS jet fan is mainly used for longitudinal ventilation of highway and railway tunnels, and can also be used in other similar occasions, such as auxiliary tunnels, sedimentation tank, etc.
The fan type
Jet fans can be unidirectional or reversible bidirectional. For reversible bidirectional jet fans, their forward flow and thrust are basically equal to their reverse flow and thrust.
Working principle of fan
The jet fan is suspended at the top of the tunnel, using the tunnel itself as the air channel. Jet fan is specially designed, can from the given the consumed power of jet power, its operation function is based on the principle of shock transmission work, through the tunnel always part of the air flow in the fan, again by export told, because exhausts and the rest of the air force change, energy is injected into the latter, This pushes the air inside the tunnel towards the exit and draws in fresh air from the entrance. Carbon monoxide concentration and turbidity air increase from the inlet point to the outlet, which is the design value. Fan installation and tunnel cross section, does not occupy traffic area, no special ventilation building, easy installation, low civil construction cost.
