Hot summer weather, high temperatures, good use of tractors, must pay attention to the following six points in order to make the tractor safe and effective operation.
1. Keep the normal water level of the cooling system. In the summer, the cooling water in the evaporation or water cooling system and the open forced circulation cooling system consumes quickly. In the work, attention should be paid to the inspection of the water level. In case of shortage, clean soft water should be added in time.
2, pay attention to the degree of water temperature meter. When the water temperature exceeds 95°C, it is necessary to stop and unload, idle and cool to prevent "opening".
3. Careful handling of the “open pan†The correct method of disposal is to allow the engine to run at an intermediate speed, open the radiator cover, and release heat. After cooling, slowly add cold water. When opening the radiator cover, the operator should stand in the upwind position, face not to face, avoid being burned by high temperature water and gas.
4, pay attention to the fan belt tension. Fan belts are loose and slippery, causing increased wear and increased power consumption. The general requirement is: When the thumb is pressed in the middle of the belt, the belt sagging amount is in the range of 10-12 mm.
5, the correct use of temperature control device. There are two kinds of thermostats, automatic and manual. Some drivers think that the sky is hot in summer, and the lower the water temperature, the better, and often remove the thermostat. In doing so, when the cold car starts, it will greatly prolong the warm-up time of the engine and accelerate the wear of the parts. Therefore, the thermostat should not be removed during the summer.
6, the correct choice of oil. In summer, the temperature is high, diesel with a higher freezing point can be used, and the correctness of the fuel feeding angle should be ensured. In addition, special attention should also be given to preventing the oil supply system from leaking oil.
