1. First determine whether the working conditions and external environment of the hydraulic system are normal, and clarify whether the fault lies in the mechanical part, the electrical control part, or the hydraulic system itself, while checking whether all system conditions meet normal operating requirements.
2. Zone judgment: Based on the fault phenomenon and characteristics, determine the zone related to the fault, gradually narrow down the fault range, inspect the components in this zone, analyze the causes, and finally locate the specific fault.
3. Comprehensive analysis of fault types: Based on the final fault phenomenon, progressively identify multiple direct or indirect possible causes. To avoid blindness, use the basic system principles for comprehensive analysis and logical judgment, reducing suspects step by step until the fault location is found.
4. When verifying possible causes, start from the most likely cause or the easiest place to check, reducing disassembly workload and improving diagnosis speed.
5. Fault diagnosis is based on operating records and certain system parameters. Keeping system operating records is the scientific basis for preventing, detecting and handling faults. For more information, please visit the clutch and brake official website.
