High summer temperatures, tractor work in high temperature environment, should pay special attention to the following questions.
1."bring" careful "boiled" when cooling water, be careful processing, the correct processing method is: the engine running at a moderate speed, open the radiator cap, gives off heat, after being cool, then slowly add cold water. When open the radiator cap, the operator should stand in the upper position, face don't toward the filler, to avoid the overflowing of hot water scald.
2. Keep the cooling system for a thorough cleaning before the arrival of summer to the cooling system of the descaling cleaning, open water pump and radiator pipe, ensure proper circulation of cooling water. In addition, still should it attached to the radiator with weeds, etc on the surface of the clean up in time.
3. To prevent the leakage of the cooling system leakage occurs at the water pump shaft sleeve, at this time the water seal gland nut proper twist tight. Such as invalid, the packing has been failure, should change in time.Packing available with asbestos rope around into a graphite powder.
4. Note the belt tensioning degree fan belt too loose, easy to slip, dropping speed of fan and water pump, wind power is insufficient; Fan belt too tight, the bearing load is too big, make wear, increase power consumption. General requirements: the thumb in the central belt press, belt sagging amount in 10 m a child 15 m range. Too loose or too tight, should timely adjust.
5, the correct use of thermal control device temperature control device has automatic type, such as thermostat and manual type (such as insulation curtains and blinds) two kinds. Some drivers think that it's hot in summer, the lower the temperature, the better, often used the thermostat down. When the car is starting to do so, in the cold, and the engine will be greatly extended the preheating time, speed up the process of wear parts. Therefore, in the summer should not put the thermostat to be removed. Insulation curtains and blinds to adjust through the radiator air flow. Summer can not commonly insulation curtains, blinds also should be put in full open position.
