How is the axial fan and duct connected?
① must make the shock absorber force evenly, otherwise it will increase the fan running noise;
③ The center of the motor and fan should be kept within the same axis range, otherwise the belt is easy to wear or fall off;
② The motor should be mounted on a movable parallel rail to adjust the center of the pulley and the elasticity of the belt;
(2) the installation of centrifugal fan is relatively complex, especially the large belt drive centrifugal fan installation, in addition to reasonable production of vibration support, the installation should also note the following:
(L) in the right and reasonable choice of fans, the quality of the installation is directly related to the normal operation of the fan. Axial fan installation is relatively simple, whether sitting or lifting, as long as the attention of the balance of the fan, vibration and the connection with the duct can be a
