How To Determine Whether The Centrifugal Fan Is Running Normally

To determine whether the centrifugal fan is operating normally, observation and inspection can be carried out from the following aspects:
Vibration situation:
Observe whether the centrifugal fan experiences significant vibration or extensive shaking during operation. Under normal circumstances, the centrifugal fan should run smoothly without any abnormal vibration.
If there is vibration, the balance of the fan rotor can be further checked. The balance of the rotor can generally be determined based on the vibration of the casing and the uniformity of the impeller rotation.
Ammeter pointer:
Check if there is any abnormal oscillation of the ammeter pointer during the operation of the centrifugal fan. Under normal circumstances, the ammeter pointer should be stable without any abnormal oscillation.
Bearing seat temperature:
Monitor whether the temperature of the bearing seat is in a normal state and within the rated temperature range. The temperature of the bearing seat should not be too high to avoid damaging the bearing or causing other malfunctions.
Fan belt:
Check for obvious jumping or breakage of the fan belt, and observe whether the tightness of the belt is appropriate. The integrity and tightness of the belt are crucial for the normal operation of the centrifugal fan.
Abnormal noise:
Monitor the centrifugal fan for any abnormal noise during operation. Under normal circumstances, the centrifugal fan should run smoothly without any abnormal noise. If there is abnormal noise, it may be caused by damage or looseness of internal components of the fan.
Operating parameters:
Check whether the technical performance and operating parameters (such as air volume, air pressure, efficiency, etc.) of the centrifugal fan meet the design requirements. If the operating parameters are abnormal, it may be due to a malfunction of the fan or the need for adjustment.
Appearance inspection:
Observe whether the casing of the centrifugal fan is free from severe wear and corrosion, and there is no air leakage. At the same time, check whether the insulation of the fan and air duct is good and whether the appearance is neat.
Lubrication device:
Check whether the lubrication device is normal, whether the lubricating grease meets the technical requirements, and whether it operates normally. The integrity of the lubrication device is equally important for the normal operation of the centrifugal fan.
Control system:
Check whether the electrical and control systems are intact, whether the protective grounding meets the requirements, and whether the motor has no serious overload or overheating phenomenon. The normal operation of the control system is an important guarantee for the normal operation of the centrifugal fan.
Through the above inspections and observations, it is possible to comprehensively determine whether the centrifugal fan is operating normally. If there are any abnormal situations, timely maintenance and repair should be carried out to ensure the normal operation of the centrifugal fan and extend its service life.
