What is the Centrifugal Fan debugging method?

A centrifugal fan is a sophisticated piece of machinery that includes an air input, damper, impeller, motor, and air exit. Its impact varies depending on the circumstances. As a result, because the working conditions of different parts are not consistent, the impact will be influenced. If you want to get to a good state, you can alter from the following factors; discover more about it by following the customized Slurry Pumps for Alumina method from China editor!

1. Centrifugal Fan supports full-voltage or reduced-voltage electric starting

However, full-voltage starting current is approximately 5-7 times the rated current, and reduced-voltage beginning torque is proportional to the square of the voltage. When grid capacity is insufficient, begin with lower voltage.

2. During the test run, carefully read the product manual and ensure that the wiring method is consistent with the wiring diagram; ensure that the working voltage of the power supply to the fan meets the requirements, that the power supply is not missing or in the same phase, and that the capacity of the distributor components meets the requirements.

3. At least two persons are present throughout the test run. One person controls the power supply, while the other watches the fan's functioning. If any abnormal occurrence is discovered, immediately stop and inspect; first, ensure that the rotation direction is proper; then, after the Centrifugal Fan begins to function, ensure that the operating current of each phase is balanced.If the current exceeds the rated current, the machine should be stopped for examination. After five minutes, stop the machine and check for any abnormalities in the fan, confirm that there are none, and then restart the machine.

4. When testing the dual-speed Centrifugal Fan, begin at low speed and verify the rotation direction; when starting at high speed, wait until the fan is motionless before starting to avoid high-speed reverse rotation, which can cause switch tripping and motor damage.

5. Once at normal speed, check that the fan's input current is normal and that the operating current of the Centrifugal Fan does not exceed its rated current. Check to see if the supplied voltage is normal if the running current exceeds its rated current.

6. The Centrifugal Fan's motor power refers to the greater power required for the Centrifugal Fan and the fan casing when the air intake is completely opened under specified working circumstances. The motor may be damaged if the air intake is fully opened for operation. Close the valve on the fan's intake or outlet pipe during the test run, and gradually open the valve after operation until the appropriate working condition is attained, paying attention to whether the fan's operating current exceeds the rated current.

The above is the editor of customized Slurry Pumps for Alumina process from China: I hope you can learn more about the related knowledge of Centrifugal Fan debugging methods.
