Normal speed and shutdown check of double inlet centrifugal fan Sep 19, 2018

In the process of commissioning the double-inlet centrifugal fan, the number of the pilots shall not be less than two. When the operation is performed, one person controls the power supply and one person observes the operation of the fan. When the operation is performed, the abnormal phenomenon is immediately stopped and the inspection is started. First check Is the direction of rotation correct?

After the double inlet centrifugal fan starts running, it should immediately check whether the running current of each phase is balanced, and whether the current exceeds the rated current. If there is any abnormality, stop the inspection. After five minutes of operation, check whether the fan is abnormal or not, and confirm that there is no abnormal phenomenon and then start up.

  

When the double-inlet centrifugal fan is being tested, the line should start at a low speed. Check whether the rotation direction is correct during operation. When starting the high speed, it must be restarted after the fan is stationary to prevent high-speed reverse rotation, causing the switch to trip and the motor to be damaged.

  

When the double inlet centrifugal fan reaches the normal speed, the input current of the fan should be measured. The operating current of the centrifugal fan cannot exceed its rated current. If the operating current exceeds its rated current, check that the supplied voltage is normal.
