      Tunnel jet fans are now widely used in various engineering fields. If the working interface of the tunnel jet fan is small, the air volume of the tunnel fan must be adjusted. The tunnel jet fan performs ventilation in the tunnel, so its air volume is generally relatively large, so its energy saving needs to be worked on. Now what are the characteristics of tunnel jet fans?

      ① Easy to repair

      The tunnel jet fan is composed of two-stage non-aluminum blades, which can be combined in the middle, which brings cheapness for assembly, repair and blade adjustment.

      ② Low noise

      The first and second generators of the tunnel jet fan are swirling, and the pressure of the fan is increasing, and the position of the atmosphere is smoothed, and the atmosphere conflict sound is increased. In addition, the casing adopts a porous lookout plate and special sound absorption information. Because the noise of parts running is under 85 decibels, the music purification has lost a significant improvement.

      ③ High efficiency

      What are the characteristics of the tunnel jet fan? The tunnel jet fan is conceived excellently and the process is conservative. Its blade adopts the ternary fluid design, with a twisted wing shape, an all-steel structure, and its position is adjustable. Due to the large working area of the tunnel jet fan, Keep working tunnel jet fans within the scope of a useful mission.

      ④ Significant energy saving effect

      The tunnel jet fan can be used in three ways in the ground moving of the tunnel. The low-speed operation within 600 meters in the later period consumes one-sixth of the total installed power. 1,500 meters running at process speed. Beijing jet fans consume one third of the total installed power. Beyond 1,500 meters, high-speed operation is used. Tunnel jet fans are equivalent to three fans without the same power. The energy saving effect is extremely remarkable.

      The basic features of the tunnel jet fan are energy saving, useful, low noise, and easy repair. For some large tunnel construction, the use of the tunnel jet fan can greatly increase its ventilation effect, and the angle of its blades It can be adjusted. As long as it is used correctly and pay attention to protection, the working efficiency of the tunnel jet fan will never decrease.




      Mechanical completion

      After the fan is installed, check the mechanical completion of the following items:

      A. Fan installation position is correct. All connection surfaces are in good contact, and the installation and connection parts are reliable without looseness.

      B. Each component is in close contact with its mounting base, and the fastener is evenly stressed. Test instruments: dial indicator, clamp ammeter (ranging from 0 to 500A), surface thermometer (ranging from 0 to 200 ° C). The specific steps of the test plan are as follows.

      a. The allowable deviation of the horizontal and vertical levels of each component of the fan meets the requirements of relevant specifications.

      b. Fan power distribution and control circuit wiring is correct and reliable.

      c. The electrical equipment and cables are well insulated and the grounding meets the requirements of relevant regulations.

      d. The fan control box is in the correct position with complete components and firm installation, and the protection level meets the requirements of the specification.

      e. The fan control box switch is flexible, the wiring inside the box is neat, and the circuit number is complete and correct.

      f. The equipment is installed correctly, there are no missing items, no debris, and the moving parts are well lubricated.

      g. When the fan starts, use a clamp ammeter with a range of 0 to 500A to measure the starting current of the motor. After the motor is running normally, measure the running current of the motor.


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

      Jet fan is a type of fan used in tunnels. The price of jet fans is because they are used in tunnels of water conservancy dams, railways, subways, highways, etc., so the air volume delivered must be uniform. When using the jet fan to transport the material, the jet fan manufacturer will greatly reduce the air volume 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.

      ② Jet fans are in the process of being delivered. The barriers for the tightness of the ducts of the ducts are not uniform through the ducts, ducts, etc., which has greatly hindered the cyclones. Jet makers, gas measurement, density and the like are also wind. During the trek, elements of the size of the barrier occur.

      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.
