Vibration reason of centrifugal induced Fan and how to solve it
Apr 28, 2019
In centrifugal induced draft fans, if the fixed parts of the fan cause vibration of the machine, then, in terms of the specific reasons and solutions, the main ones 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-grouting.
(2) the foot bolt in the fan is loose or the base connection is not strong. The concrete treatment is to fasten the ground bolt or fasten the joint.
(3) when the base and volute of centrifugal induced fan are low, the stiffness of centrifugal induced fan should be strengthened.
(4) when the inlet and outlet pipes of centrifugal induced fans are not supported and soft connected, or the foundation of other equipment is too close to the foundation of centrifugal induced draft fan, support or soft connection should be installed, or its stiffness should be increased.
In addition, the other equipment foundation and centrifugal fan foundation, properly extended to the appropriate distance.www.jnblower.com
