Overview

SDS Traffic Tunnel Jet Fan Full Horizontal Ventilation System: Supply and exhaust ducts are set along the tunnel direction, with fresh air collected from the wind pavilion and exhaust air discharged from the wind tower. Generally, the supply duct is set below the road surface, and the exhaust duct is set at the upper part of the lane. Supply and exhaust vents are set at regular intervals between the supply and exhaust ducts, and smoke is extracted by timely exhaust along the tunnel cross-section under accident conditions. The performance indicators, corrosion resistance, reliability, economy and other technical, quality requirements and economic indicators of the fan can adapt to the use of various tunnels and subways.

Product Details

SDS Traffic Tunnel Jet FanAdopting the * process to achieve good quality assurance, the fan casing is formed by spinning and flanging on the machine tool, and the inner wall of the impeller section is machined with gold to ensure the coaxiality and strength of the casing, as well as the radial clearance of the blades. The outer surface is treated with hot-dip galvanizing or other equivalent coating, which is beautiful and corrosion-resistant, with excellent performance. The fan blades and hub machining center are processed into die-casting mold cavities, and aluminum alloy high (low) die-casting is carried out on high-pressure casting and low-pressure casting machines respectively. Through actual use by users such as highway tunnels, railway tunnels, and water conservancy dam projects, the performance indicators, corrosion resistance, reliability, economy and other technical, quality requirements and economic indicators of the fan are fully adapted to the use of various tunnels and subways.

SDS Traffic Tunnel Jet Fancomposition

1. Centrifugal fan itself, muffler, and support bracket: Thick steel plate CNC machine tool is used for fully automatic welding and system forming, and surface coating is used to ensure the compressive strength and corrosion resistance of the centrifugal fan.

2. Centrifugal impeller: In order to consider the necessity of tunnel ventilation, SDS series centrifugal fans can change the number of leaves and the angle of view of the centrifugal fan leaves.

3. Muffler: The length of the muffler is generally several times the diameter of the centrifugal fan. When the noise level is high, it can also be twice the diameter of the centrifugal fan. The muffler and the centrifugal fan themselves are fixed with anchor bolts.

4. Supporting facilities motor: The SDS series product water jet ventilation fan supporting facilities motor is a squirrel cage enclosed type, with a flange mounting plate under the motor. The flame retardant rating of the motor is H level, and the anti-corrosion rating is IP55. The motor can be connected to the wiring terminal on the outer shell of the centrifugal fan by finding the cable. The motor contains a lubricating grease nozzle, and an external metal corrugated pipe is connected to the lubricating grease nozzle on the outer shell of the centrifugal fan.

5. Reversibility conversion time of centrifugal fan: In emergency situations, the forward and reverse conversion time of jet fan is extremely important. SDS (R) centrifugal fan has two conversion modes: electronic and foot operated, which can be converted to the rated speed ratio of centrifugal fan within 30 seconds.
