      Jet unloading in tunnel

      a. Determine the location where each fan should be installed, and transport it to this location. Due to the large size, length, and heavy cargo of the fan transport vehicle, there should be 2-3 personnel to direct the traffic in the tunnel, and the vehicle should be moved slowly.

      b. When the fan is delivered in place, remove the fan and place it properly, waiting for disassembly and installation.

      This process should be set up with a crane driver, which is a good jet fan, 2 cranes to operate uniformly, and strictly observe the lifting operation procedures.

      Laying and connecting cables

      The fan leads are concealed by steel pipes and communicate with the cable trench. Check that the cable specifications and designs are consistent with the design and whether the connection phase sequence is consistent with the design drawings.


      Reasons for the decrease of air volume during the use of jet fans

      Jet fan is a type of fan used in tunnels. Because the scale used is used in tunnels of water conservancy dams, railways, subways, highways, etc., the air flow must be uniform. When the jet fan used in When transporting material, the air volume will decrease greatly after reaching a certain position. This is why?

      ① When the air duct of the jet fan is placed in the tunnel, it may be because there is no regular placement, or the air duct shows damage such as leakage, breakage, etc., causing the air volume to decrease.

      ②The jet fan is in the process of being transported. The tightness of the duct of the duct is not uniform through the duct, duct, etc., and it is a great obstacle to cyclones. Gas measurement, density, and the like are also the process of the wind trekking. , Jet fan manufacturers, the factors that cause the size of the barrier.

      ③ Regarding the rotary axial flow fan normally adopted by the jet fan, the dual-generator type is adopted, so that the pressure of the fan is much greater than that of the single generator. After the fan is started, the stability of the external voltage will satisfy the speed of the generator. Increasing or shrinking of care.




      Design and Calculation of Tunnel Jet Flow Fan Layout

      In order to meet the needs of road tunnel ventilation and noise reduction, the influencing factors of jet fan thrust and its selection requirements are proposed. The thrust of the jet fan is determined on the premise of calculating the total thrust in the tunnel. And determine the number of fans used.

      In the longitudinal ventilation system of a highway tunnel, jet fans are usually connected in parallel as a group and spaced along the tunnel direction. In order to meet the requirements of the noise environment in the tunnel, the jet fans are usually equipped with integral mufflers. At night, in order to prevent large noise at the tunnel entrance, Jiangsu jet fans usually run only the fan in the middle of the tunnel, or extend the length of the fan muffler near the tunnel entrance, or use a dual-speed jet fan.
