Centrifugal fans are widely used in industrial production as ventilation and exhaust equipment, but often, due to a lack of relevant expertise, they are neglected after installation.

In fact, centrifugal fans can achieve different results under various conditions. Therefore, it is crucial to properly debug the fan to ensure it is operating in the optimal state. Below is a detailed explanation of the centrifugal fan debugging process:

1. Start Method: The fan can either be started under full voltage or reduced voltage. However, when starting with full voltage, the rated current is approximately 5-7 times the normal value. When the power grid capacity is insufficient, reduced voltage start should be used.

2. Pre-Operation Check: Before starting the test operation, carefully read the product manual and ensure the wiring method matches the wiring diagram. Check that the operating voltage of the fan’s power supply meets the requirements, and ensure there is no phase loss or phase reversal. Also, verify that the capacity of the electrical components in the distribution panel meets the requirements.

3. Test Run: The test run should involve at least two people: one controlling the power supply and the other observing the fan’s operation. If any abnormal phenomena occur, immediately stop the fan and perform a check.

   • First, check if the rotation direction is correct.
   • After the fan starts running, immediately check if the running current of each phase is balanced and whether it exceeds the rated current.
   • If any anomalies are found, stop the fan for inspection.
   • After running for five minutes, stop the fan and check if there are any abnormal phenomena. Only restart the fan once it is confirmed that there are no issues.

These steps will help ensure the centrifugal fan is properly debugged and running efficiently.
