Precautions for assembling the tunnel jet fan
Tunnel jet fan machinery manufacturing enterprises generally adopt more stringent quality standards in the process of fan manufacturing, but air manufacturing enterprises in addition to strict quality control, is also an important part of fan assembly, the installation efficiency of tunnel jet fan equipment is seriously damaged.
Therefore, the assembly of tunnel jet fan must be serious and strict implementation of standards. When installing, first of all, it is necessary to make the guide plate based on the base. When setting it on the mounting platform, the cut surface is properly protected on the base. Pay attention to corrosion and other adverse phenomena.
Note the tight connection between the bearing and the flywheel fan base. In general, the vertical at 0.2 is not evaluated as 1000, and the horizontal is not evaluated as 0. Bearings must be modified. Before meeting the requirements of this standard, the rotating shaft and housing must be corrected.
In addition, when installing the shell of the tunnel jet fan, the staff must first install the standard parts, which should generally be placed on the wheel shaft to determine the position of the lathe, and then determine the axial distance between the impeller input and the body, decide whether to connect the bolts, adjust the axial spacing, and adjust the efficiency of the tunnel jet fan.
