How much do you know about the debugging method of Best Centrifugal fan For sale? Let’s take a look at it briefly below!
1. Best Centrifugal fan For sale allows full-voltage starting or step-down electric motor, but it should be noted that the current during full-voltage starting is about 5-7 times the rated current, and the step-down starting torque is proportional to the square of the voltage. When it is not enough, it should be started with reduced voltage.
2. During the commissioning of Best Centrifugal fan For sale, you should carefully read the product manual and check whether the wiring method is consistent with the wiring diagram; you should carefully check whether the working voltage of the fan power supply meets the requirements, whether the power supply is out of phase or in the same phase, and the matching Whether the capacity of electrical components meets the requirements.

3. There should be no less than two people during the test run, one person controls the power supply, and the other person observes the operation of the fan. If any abnormality is found, immediately stop the inspection; first check whether the rotation direction is correct; after the Best Centrifugal fan For sale starts to operate, the operation of each phase should be checked immediately. Check whether the current is balanced and whether the current exceeds the rated current; if there is any abnormal phenomenon, it should be stopped for inspection. After running for five minutes, stop the fan to check whether there is any abnormal phenomenon, and then start the operation after confirming that there is no abnormal phenomenon.
4. When testing the two-speed Best Centrifugal fan For sale, start at low speed first to check whether the rotation direction is correct; when starting at high speed, you need to wait for the fan to stop before starting it, to prevent the high-speed reverse rotation, which may cause the switch to trip and the motor to be damaged.
5. When the Best Centrifugal fan For sale reaches the normal speed, it should be measured whether the input current of the fan is normal, and the operating current of the Best Centrifugal fan For sale cannot exceed its rated current. If the operating current exceeds its rated current, check whether the supplied voltage is normal.
