      Installation of jet fan in place

      a. Before installing the fan, the fan number, model, transmission method, impeller rotation direction, and air outlet position must be checked.

      b. Fan installation adopts a professional jet fan installation vehicle for hoisting in place. Soft rigging should be used for the rigging at the strapping point of the fan, so as not to damage the paint layer of the equipment. The rotor, journal and shaft seal should not be used as binding parts.

      c. Before the fan is bundled, a self-made channel steel frame is placed underneath. A block of wood should be placed between the fan and the frame to reduce the operation of the fan. After making the above preparations, bundle the fan with the frame, and the Shaanxi jet fan for hoisting.

      d. There are two operators on the professional fan installation vehicle, which adjusts the fan to the corresponding position from front to back, left and right, and one operator on the ground is responsible for up and down coordination and unified command for safe and fast installation.

      e. Adjust the position of the fan. After the position adjustment is completed, install the bolts between the fan and the connecting accessories, and tighten the connecting bolts. A set of flat washers, a set of spring washers, and a fastening nut should be added to each connecting bolt to prevent the fan from running and the nuts become loose. The exposed part of the bolt screw after tightening should have a pitch of 2-3.

      f. Specification deviation: The fan after installation should meet the following requirements:

      The plane of the centerline is moved back below 10mm, the elevation is within ± 10mm, which is the best for a jet fan, theodolite or pull line and ruler check, level or level, ruler, pull line and ruler check

      The concentricity of the coupling is less than 0.05mm in the longitudinal direction and less than 0.2 ‰ in the axial direction. Use four positions where the couplings are perpendicular to each other, and check with a dial indicator. The elevation of the bottom of the fan may be above the height limit line.


      During the operation of the tunnel fan, it was found that the fan body was always shaking, and even internal noise appeared. This is mainly due to internal friction. After some parts are loosened or lubricated for a long time, the friction and friction between the parts of the tunnel jet fan and the parts are increased, thereby producing the final result. In the face of the vibration and noise generated by the fan in this phenomenon, we need to make appropriate judgments and solutions to various situations, so the next edition will simply analyze the reasons for the friction of the fan.

      This is lost on the fan. Therefore, when using tunnel fans, it is necessary to pay attention to the convenience brought by the conflict. The conflict did not occur only in the name of two objects in contact with each other, the jet fan manufacturer, and also occurred outside the province.

      There are many reasons for friction in tunnel jet fans. On the other hand it is related to the impeller. If the tilt of the impeller is not enough to withstand the rigidity of the chassis or the chassis jet fan, the impeller will swing left and right, causing friction. The following results were obtained even after the impeller disc and the collector collided. Proper adjustment of the gap between the impeller disc and the collector can reduce this problem.

      If the gasket is changed and the gap between the gasket and the sealing teeth is adjusted, the gasket can be in contact with the sealing teeth of the electric fan. In another range, it leaves the thrust bearing without the tunnel fan. Once deformed or not well-balanced, it can cause conflict.




      Air velocity in the tunnel, proximity of fans to walls and vaults

      Fan thrust is measured under air static conditions based on the change in air momentum of the fan. If the air at the fan inlet is in a moving state, the change in the air momentum in the fan must be reduced. If the installation location of the jet fan is close to the tunnel wall or vault, additional friction loss will inevitably occur between the air jet and the wall or vault.

      Fan size

      The ratio of power consumption and thrust of a jet fan is related to the wind speed at the exit of the fan. For a given thrust requirement, the higher the outlet wind speed, the greater the power consumption. Therefore, in order to reduce operating costs, fans with large diameter, low speed or small blade angle should be selected as much as possible. For a given fan size, if its thrust is reduced, it will inevitably lead to an increase in the number of fans, thereby increasing the investment in the fan itself, but at this time the wind speed at the outlet of the fan will also be reduced, making the muffler cancel or reduce its length.

      Reversible fan

      Compared with unidirectional fans, reversible fans are slightly less efficient and have higher noise, but they can make tunnels more selective. In the case of special needs, the one-way tunnel can be used for two-way operation. In the event of a fire, the fan can reverse the exhaust smoke.
