Circuit failure is one of the main causes of faults in the electrical system of excavators. Common fault factors include poor contact, short circuit, open circuit, etc. During the inspection, it is necessary to check the key components in the circuit system one by one, such as switches, relays, etc., to eliminate the fault factors. At the same time, it is necessary to check whether the cables are damaged and replace them in time.
Motor failure is one of the common faults in the electrical system of excavators, which is mainly manifested as abnormal motor operation and difficulty in starting the motor. During the inspection, it is necessary to check the power supply of the motor first to confirm whether the power supply is normal. If the power supply is normal, you can check whether the motor winding has short circuit, open circuit, etc., and you need to check whether the motor bearing and transmission part are normal.
Sensor failure is one of the common faults in the electrical system of excavators, which will cause problems such as unstable operation and reduced accuracy of the excavator. During the inspection, it is necessary to first confirm whether the sensor power supply is normal, and then check whether the signal output of the sensor is normal. If a fault occurs, it needs to be replaced in time to avoid affecting the normal operation of the excavator.
The electronic control unit is the control center of the electrical system of the excavator. If a fault occurs, the excavator will work abnormally. During the inspection, you need to first check the entire circuit system to determine the scope of the fault, and then check whether the electronic control unit is normal in combination with the performance of abnormal work. If replacement is required, it is recommended to choose a regular brand designated repair center for replacement.
As the excavator ages, the electrical circuit may age, leading to electrical system failures. During the inspection, it is necessary to check whether the electrical circuits are damaged or aged one by one, and replace the electrical circuits in time to ensure the normal operation of the excavator electrical system.
