Method of debugging centrifugal fan (1)

Mar 07, 2020

1 Centrifugal fan can start with full pressure or step-down, but it should be noted that the step-down starting torque is proportional to the square of the voltage, and when the power grid capacity is insufficient, the step-down starting should be adopted.

2 Centrifugal fan in the test run, should carefully read the product specification, check whether the wiring method is consistent with the wiring diagram; should carefully check whether the supply fan power supply working voltage is not in line with the requirements, whether the power supply is lack of phase or phase, the capacity of the distribution components meet the requirements.

3 The number of people in the test run is not less than two, one person controls the power supply, one person observes the fan operation condition, discovers the abnormal phenomenon to stop immediately to check; first checks whether the rotation direction is correct; immediately after the centrifugal fan starts operation, should check each phase operation current balance, whether the current exceeds the rated current; if has the abnormal phenomenon, should stop to check. After five minutes of operation, stop to check whether the fan has abnormal phenomenon, confirm that there is no abnormal phenomenon before starting operation.
