What principles should be when analyzing tractor faults?
Tractor is a kind of machinery commonly used in agricultural production, which can mainly replace human to complete various agricultural operations, such as tillage, planting, plant protection, transportation, etc. However, as a machine, faults occur from time to time. What principles should be when analyzing tractor faults? Let's get to know.
Principles to follow when analyzing tractor faults
1.Do not disassemble or unload randomly.
2.Reasonably infer and analyze the faults according to the functions, principles, structural characteristics and their interrelationships of each component.
3.We should follow the principles of from simple to complex, from outside to inside, from easy to difficult, and according to the system.
4.We should be good at summarizing and accumulating experience.
5.Specific solutions shall be taken for specific fault problems
Troubleshooting of tractor faults
1.The automatic skip after gear change is mainly caused by the wear of the fork shaft groove, the weakening of the fork spring, and the excessive clearance of the connecting rod joint. At this time, the normal speed change can be ensured by repairing the positioning slot, replacing the fork spring and reducing the clearance of the connecting rod joint.
2.There are three main reasons for the abnormal noise of the gearbox: the first may be that the bearing in the gearbox is seriously worn or damaged, and the bearing should be replaced in time; The second possibility is that the working tooth surface of the gear is worn, pitted, glued or broken, and the damaged gear should be replaced in time; The third possibility is that the amount of lubricating oil is insufficient and should be filled in time.
3.The main reason for steering wheel steering failure is that the return spring plate in the steering gear is broken, which causes the steering wheel to not return automatically. The spring plate can be replaced.
4.The high pressure oil pipe is worn and leaked. The protruding head at both ends of the high pressure oil pipe of the tractor and the connection between the fuel injector and the oil outlet valve are worn and leaked. A round copper sheet can be cut from the waste cylinder pad, and a small hole in the middle to be worn and smooth, and the pad can be placed between the convex pits.
5.The main manifestations of lax valve closing are engine starting difficulty, power reduction, black smoke, etc. The reason is that there are carbon deposits, ablation, spots and even peeling between the valve and the valve seat. The valve seat can be reamed and polished. If the problem is serious, the valve and valve seat can be replaced directly.
6.If the water inlet and outlet pipe is not broken to a large extent, the water pipe can be wiped clean with a cloth, and then the water leakage can be bound and fastened with a cloth strip coated with soap.
In general, in case of tractor failure, certain diagnostic methods must be to avoid random disassembly and maintenance. The key is to analyze the cause of the failure and then do a good job of "the right medicine".
