Why does fan impeller stop and should not stay in the same position every time?
Prevent the shaft bending when the machine is stopped for a long time. In the normal condition of the dynamic and static balance, it will not stop in the same position. If the long-term downtime, the best period of time to rotate 180 degrees
Should not be, but generally do not stay in the same location, you can from the probability. Receive the stop order, the blade clockwise, the speed reached a certain low degree of braking. As the wind conditions are different, when the order is stopped, the impeller position is not the same, the speed is not the same, so stop at the same location, the probability is very low.
Fan impeller stop, if you stay at the same location, fan impeller static balance is a problem, turn up, shaking must be large
