In hot summer weather, the working conditions of the tractor are poor. If it is used improperly, it is prone to malfunction or accident. To this end, special attention should be paid to the following aspects: 1, to prevent the water temperature is too high: to use scale remover and other cooling system's scale and impurities thoroughly cleaned to ensure that the cooling water circulation. In the summer, the cooling water evaporates quickly. Before you leave the car, you must add enough soft water and check the water level frequently during work. If the water temperature exceeds 95°C, it is forbidden to extinguish immediately when the pot is opened and suddenly add cold water or pour with cold water. Otherwise, it is easy to make the cylinder block, cylinder head, etc. burst, and the engine should be run at an intermediate speed to open the radiator cover and release hot gas. After the water temperature drops to about 60°C, add cooling water slowly. When opening the radiator cover, the operator should stand in the upwind position, face not to face the water inlet, so as not to be burned by high temperature steam. 2, the normal choice of oil: Summer temperatures are high, you can use a higher freezing point of diesel oil, and to ensure the correctness of the fuel supply advance angle, the summer should be adjusted to the oil supply time to the lower limit or slightly lower. If the oil supply time is too early, the engine will have a severe knocking sound, the crank connecting rod mechanism will be subject to large impact, the wear of the machine parts will be intensified, and the reversal phenomenon will occur. The time for supplying oil is too late. If it is too late, it will catch fire, the combustion period will be prolonged, the combustion will be insufficient, the engine will fail to work, and the engine will easily overheat. In addition, special attention should also be paid to preventing oil spills in the oil supply system because oil spills not only result in wastage of oil, but also cause fires. In addition to diesel, high viscosity lubricating oils and greases should also be used. Lubricating oils have high viscosity, which can improve lubricating performance and increase sealing performance. When replacing the lubricating oil, thoroughly clean the oil filter, the filter, and the oil pan once to remove the dirt and impurities. The diesel engine equipped with a changeover switch should be turned to the "summer" position in summer so that the oil can be discharged into the main oil passage after being cooled by the radiator to prevent the viscosity from decreasing. 3. Pay attention to the maintenance of the battery: In the summer, the electrolyte in the battery will be sucked out, add proper amount of distilled water, and control the specific gravity of the electrolyte to about 1.25. When the temperature is high, the electrolyte is easy to evaporate. The liquid level should be checked once every 5 to 10 days (normally 10 to 15 mm above the plate). When it is insufficient, add distilled water. The battery should always be fully charged. The ventilation hole on the filler cap should be dredged. Store unused batteries in a cool, ventilated place. 4. Reasonable use and storage: During the summer season, the tractor operation should avoid overload operation and should be controlled at about 85%. Noon radiator easy to open the pot, the driver is also easy to fatigue, as far as possible arrangements for morning and evening operations. Pay special attention to fire prevention. Check the oil supply system to prevent oil leakage. The exhaust port of the tractor should face upwards and a Mars collector or safety guard should be installed. It is forbidden for the workers to smoke in the work area. Do not overhaul and start the work site. locomotive. Summer tire pressure is preferably 2% to 5% lower than standard air pressure. When the tractor is not working, it is best to park in the shade or in the hangar. In the hot sun, the tires should be covered with straw, etc. It is best to park in the garage at night. When storing in the open air, cover with a plastic cloth.
