Common faults and solutions of environmental protection single shaft shredder
A, description,
Pay attention to safety during troubleshooting. Operators must ensure that the machine is powered off, fuses are removed, and service labels are put on. Tested instruments must be used. The meter must be able to measure twice the AC and DC current of the machine, and the voltmeter must be able to measure the resistivity of 5,000 ohm/v at AC current and 20,000 ohm/v at DC current. VOM or VTVM instrumentation can be added to help with detection when needed.
Before replacing the circuit elements, users are advised to make a detailed test according to the circuit diagram before the replacement. Circuit fault troubleshooting is not clear, easy to burn the new original, resulting in waste.
