Online sterilization centrifugeAfter turning on the power, the control panel will display normal and the cooling fan will work normally. When the start button is pressed, the intermediate relay will work and the centrifuge will not work. According to the analysis of the fault phenomenon, the power supply and control parts should be normal, and the fault should be in the circuit from the control board to the motor, the carbon brush, and the motor. Open the centrifuge and use a multimeter to measure the continuity of the circuit from the control board to the carbon brush. Then measure that the carbon brush is not conducting to the motor rotor. Carefully observe the poor contact between the carbon brush and the motor rotor. After removing the carbon brush, it was found that it was caused by too long or too short usage time. Replace the carbon brush with a new one and troubleshoot the issue. This type of malfunction is a common problem with centrifuges, and it is necessary to regularly replace the carbon brush to avoid the above malfunctions.

After the online sterilization centrifuge is powered on, the control panel displays normally and the cooling fan works normally. When the start button is pressed, the intermediate relay does not work and the centrifuge does not work. According to the analysis of the fault phenomenon, the power supply should be normal, and the fault should be in the control board and the circuit to the motor, carbon brush, and motor. Turn on the centrifuge and use a multimeter to measure the continuity of the circuit from the control board to the carbon brush. Then measure the continuity of the circuit from the carbon brush to the motor rotor, and confirm that the motor coil is normal.
