      Influencing factors and selection of jet fan thrust

      Longitudinal distance between each group of fans

      If there is a sufficient distance between each group of fans in the tunnel, the jet airflow will slow down gradually. If the jet airflow is not completely slowed down, it will affect the working performance of the next-stage fan. Under normal circumstances, the vertical distance between each group of Jiangxi jet fans is taken as 10 times or more than the hydraulic equivalent diameter of the tunnel section. The price of the jet fan can also be one tenth of the air dynamic pressure (Pa) of the fan. As the longitudinal distance (m) of the fan, the center distance between the same group of fans is at least 2 times the diameter of the fan. The arrangement of the jet fans in the tunnel does not necessarily have the same spacing. As long as there is sufficient longitudinal spacing between the fans, the fans can be arranged as close to the tunnel opening as possible; if the axial installation position of the fans allows a certain tilt, the fans The longitudinal distance between them can be reduced, which can increase the installation factor.




      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.

      ② Jet fans are in the process of being delivered. The barriers for the tightness of the ducts of the duct fans are not uniform through the ducts, ducts, etc., and they are a great obstacle to cyclones. 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.




      Disassembly inspection of jet fan

      Determination of insulation performance of electric machines. Divided into the insulation resistance test between the three phases of the terminal, and the measurement of the insulation resistance between the fan housing by each terminal.

      The disassembly and inspection of the muffler shall meet the following requirements:

      a. The muffler must not be damaged or wet during transportation, and the filled muffler material should not sink significantly.

      b. The outer surface of the muffler should be flat, and there should be no obvious unevenness, scratches and rust.

      c. The screws that fasten the muffler parts should be evenly distributed, the joints should be flat, and they should not be loosened or come off.

      d. The surface of the perforated plate should be clean and free of rust and blockage of holes.

      e. The fiberglass-lined cloth should be flat and undamaged.
