In the centrifugal draft fan, if the fixing parts cause the machine to vibrate, then the specific reasons and solutions are:
(1) The cement foundation in the fan is too light, or its plane size is too small. At this time, the foundation should be strengthened or re-grouted.
(2) The anchor bolts in the fan are loose or the base connection is not secure. The specific treatment is to fasten the anchor bolts or to fasten the joints.
(3) The base of the centrifugal draft fan and the volute stiffness are too low, and the rigidity should be strengthened.
(4) The inlet and outlet pipes of the centrifugal draft fan are not equipped with support and soft connection, or the foundation of other equipment and the centrifugal draft fan are too close. At this time, support or soft connection should be added, or Stiffness.
In addition, the distance between the other equipment base and the centrifugal draft fan base is appropriately extended to a suitable distance.
