In what circumstances should an emergency shutdown be performed on a corrosion-resistant duct fan?

As users of corrosion-resistant duct fans, we may encounter emergencies and incidents during the production process. To minimise losses, it is essential to take prompt action in such situations. This also applies to the operation of corrosion-resistant duct fan systems. Therefore, should an unforeseen situation arise, the fan must be shut down as soon as possible. So, what exactly constitutes an emergency shutdown? In the case of centrifugal fans, an emergency shutdown involves pressing the stop button on the main motor to halt the unit, followed by the execution of residual operations. So, under what circumstances is it necessary to take such measures? I hope the following summary will prove helpful. Generally, during the actual operation of corrosion-resistant duct fans, emergency shutdown measures should be implemented when the following situations arise: 1. The corrosion-resistant duct fan suddenly experiences severe vibration exceeding a certain threshold. 2. There is damage inside the machine or abnormal friction noises are heard. 3. There is smoke emanating from the bearings or seals inside the machine, or the bearing temperature rises sharply to the alarm level. 4. The oil pressure falls below the alarm level and cannot be restored to normal. 5. The liquid level in the oil tank is too low, which may cause cavitation. In addition to the above, if the axial displacement of the centrifugal fan increases significantly and reaches the alarm threshold, an emergency stop must be initiated. Therefore, when using corrosion-resistant duct fans, it is essential to be fully aware of these issues. Only then can correct and timely measures be taken in an emergency to protect production equipment as much as possible and minimise losses.
