How to deal with the sudden stop of centrifugal fan

If it is found that the centrifugal fan equipment suddenly stops running, it is necessary to find the actual reason first, and then solve the problem by using a purposeful method according to the situation. So, why does the centrifugal fan equipment suddenly stop rotating in the operation link? Encounter this kind of problem, how should we do maintenance?

First of all, in view of the sudden stop of rotation of centrifugal fan equipment, the factors specifically include three aspects:

1. Transmission line connection head loose or bad contact phenomenon;

2. Generator fuse is blown;

3. The unit has short circuit or open circuit common faults.

For the reasons listed above, we should adopt the maintenance strategy is:

1. Check whether the connection head of the power transmission line on the centrifugal fan equipment is loose and whether there is bad oxidation contact. If so, remove the oxide immediately and complete the connection again;

2. If the fuse is found to be broken, replace the fuse of the same size;

3. Check whether there is short circuit or open circuit problem in transmission lines and rectifier circuits.

So, how can you identify exactly where the circuit breaker occurred, where the short circuit occurred? First of all, the inspection content for the common fault of circuit break is as follows: measuring whether there is voltage output at the output end of centrifugal fan, internal wire break of transmission line, rectifier diode or motor coil break. You can use a multimeter R*100 ω block to carry out the test to find the breaking point, and then remove the damaged electronic devices.
