The technical points of tractor fault diagnosis and removal mainly include the following aspects:
1. Observation and judgment: First of all, by observing the tractor's working state, sound, temperature, etc., preliminary judgment of possible faults. For example, notice if the engine makes an abnormal sound or if there is overheating.
2. Diagnosis method selection: Select an appropriate diagnosis method based on the fault symptom. If the comparison method is used, the fault is eliminated by replacing the parts; Or use the instrument method, the use of special tools for accurate detection.
3. Step by step elimination: For complex faults, step by step elimination is required. Start with a simple cause and work your way up until the fault is found and eliminated.
4. No disassembly or less disassembly diagnosis: In order to reduce the damage to new parts, try to use no disassembly or less disassembly diagnostic methods. For example, by checking the oil level, water level, and non-contact detection using tools such as infrared thermometers.
5. Combination of experience: In the diagnosis process, make full use of their own experience and professional knowledge, combined with the tractor manual and maintenance information, to improve the accuracy and efficiency of diagnosis.
In short, the key points of the tractor fault diagnosis and removal technology are careful observation, choosing the appropriate method, gradually eliminating the fault, trying not to disassemble or disassemble the diagnosis, and combining experience and professional knowledge to make accurate judgments.
