1, the fan belt is too loose to make the fan and the pump and the speed is not enough. Too loose or too tight a belt will accelerate the wear of the belt and accelerate the wear of the bearing. Too loose a belt will also reduce the cooling power of the cooling water and cause the engine to overheat. Should be in accordance with the requirements of the instructions, hand-moving fan or pull the middle of the belt, check the tightness of the fan belt, the tightness is not correct, should be adjusted. If two of the fan belts are damaged, they should be replaced as much as possible. Two tight ones should accelerate the wear of the belts and bearings.

2, water tank water shortage. The water did not increase enough, or there was a leak. As the amount of cooling water is insufficient, the temperature of the cooling water rises sharply and the engine is overheated. At this time, the engine should be immediately shut down. After cooling for a period of time, add cooling water and check for leaks. If any, tap the plugging measures and repair.
3. When the engine is overloaded for a long time, the fuel emits more heat, but the engine speed is low and the cooling effect is poor, so the cooling water warms up quickly, causing the engine to overheat. In this case, you should think of ways to reduce the load on the locomotive and work on the downshift to solve the engine overload problem.
4, the engine fuel supply advance angle is too small, the combustion will be carried out under a large cylinder volume, to give more cooling water heat, making it warm up quickly, causing the engine to overheat. At this time, the engine often smokes black smoke, and the exhaust pipe may ignite fire, especially at night. This is mainly due to wear of the plunger pair wear, timing gears, cams, etc., or installation errors, which can cause changes in the advance angle of the fuel supply. At this time, it is necessary to recheck the adjustment of the oil supply time and replace worn parts.
5. The wear of the pump impeller's end face reduces the pump's water capacity, or the pump impeller does not rotate. The cooling water is not circulated and cooled, so the temperature rises quickly and the engine overheats. At this point, the pump should be fully inspected, and new or new products should be repaired depending on the degree of damage to the impeller, shaft or housing.
6. The use of hard water that has not been softened for a long period of time will increase the scale in the water jacket and the radiator, as well as block the radiator water pipes, causing cooling water to cool and poor heat dissipation, causing the engine to overheat. Rinse the radiator with clean water and compressed air, then add 10kg of water, 0.75kg of caustic soda and 0.25kg of detergent to the water tank, work for one shift, turn off the engine after extinguishing, exchange fresh water, and let the engine run at medium speed. , Wash with water 2 or 3 times.
