Tractor, car breakdown symptoms
Practice tells us that both the engine and the chassis part have different symptoms due to their failure. Based on these external symptoms, it can be concluded whether the tractor or the car is faulty. To troubleshoot a problem successfully, you must first become familiar with its external symptoms. Although there are many kinds of faults, the following categories are generally summed up according to their laws: 1. Abrupt changes in operating conditions. The so-called abrupt change in working conditions refers to sudden changes in the working conditions of tractors and automobiles. This is a relatively common fault symptom. For example, after the engine suddenly shuts off, it is difficult to start, and it is even impossible to start a fire; the power of the engine suddenly decreases during operation, making the tractor and the vehicle unable to move; sudden brake failure or deviation in running, or even failure. Because of the obvious symptoms of this kind of failure, it is easy to detect, but the causes are complex, and the sudden change of working conditions often results from gradual changes to sudden changes. Therefore, it is necessary to carefully analyze the diagnosis, recall any suspicious symptoms before the mutation, eliminate false positives, and identify failures. Where 2. The sound is abnormal. Some faults often cause abnormal sounds on the engine or chassis. This type of fault is obvious and can generally be detected in time. Some abnormal sound failures can cause mechanical damage and must be taken seriously. Practice has shown that wherever the sound is heavy and accompanied by turbulence, there are many malignancies and the cause should be identified in a timely manner. 3. Overheating. Overheating is usually found on engines, transmissions, and rear axle assemblies. Under normal circumstances, these assemblies should be kept within a certain working temperature range regardless of how long tractors and cars work. In addition to the engine, it feels hot and unbearable by touching it with your hand, indicating overheating. Such as: engine overheating may be a fault in the cooling system must be promptly removed, otherwise it will cause a piston cylinder and other major accidents. Transmission bearings are overheated, lack of lubrication, bearing damage, or excessive preload adjustment. Therefore, special attention must be paid to overheating. 4. Leakage phenomenon. Leakage refers to the leakage of fuel, lubricating oil, hydraulic oil, and water. This is also an obvious symptom of failure. Observe directly. Such as: hydraulic oil leakage will cause the gear pump to empty, so that the oil pump overheating, bushing burning, agricultural tools to improve and other difficulties. Once found it should be immediately ruled out. 5. The color of smoke is not normal. During engine operation, the main components of normal combustion products should be carbon dioxide and a small amount of water vapor. If the combustion is not normal, the exhaust gas contains unburned carbon particles, hydrocarbons, carbon monoxide or a large amount of water vapor, and in addition, hydrogen peroxide and the like. The color of these may become black, white, and blue, that is, the smoke is not normal. Smoke color is not normal at the same time, often accompanied by the engine is weak or difficult to launch and other phenomena. Therefore, whether the exhaust color is normal or not has become an important basis for determining faults. 6. Abnormal fuel and lubricant consumption. The increase in fuel consumption is generally due to improper engine operation or improper adjustment of the chassis's drive train, brake system, and travel system. Excessive oil consumption, in addition to leakage causes, many engine failures, then often with a large number of organic oil outlet smoke, exhaust blue smoke. The main reason is that the gap between the cylinder sleeve and the piston is too large or seriously damaged. If lubricating oil increases unabated, except for the addition of cooling water or diesel oil, the oil seal may be damaged before the hydraulic gear pump. Therefore, abnormal consumption of fuel and lubricating oil is one of the important symptoms of engine failure. 7. There is a special smell. When a tractor or a car is in motion, if there is brake delay or if the clutch or steering gear slips heavily, the burning odor of the friction plate will be issued, and the circuit will be short-circuited and the wire will burn when it is burned. If you smell unusual odors while driving, you should stop immediately and identify the problem. Author: Wuyuan County Agricultural Machinery Supervision Station, Heilongjiang Province
