Engine cooling parts Fan with clutch for DAF 1263571 1248893

The function of the engine cooling fan is to enhance the air velocity and flow through the diffuser to improve the heat dissipation effect of the radiator. The fan is an important component in the engine cooling system. Its performance not only directly affects the heat dissipation efficiency of the radiator, but also affects the normal use and reliability of the engine.

Many parts of a car need to dissipate heat during operation, so there are many places inside the car that need to be installed with fans, including clutch fans, electronically controlled fans, and general cooling fans.

Ordinary cooling fan

The fan is located between the radiator and the body, is installed on the same shaft as the water pump, and is driven by a pulley on the crankshaft. The fan and the pulley hub are connected by bolts, and the engine crankshaft pulley directly or indirectly drives the fan to rotate.

The tightness of each belt should be adjusted according to regulations. The tightness of the fan belt is too loose, causing the fan pulley speed to decrease, the heat dissipation of the water tank is weakened, the diesel engine working temperature is increased, and the generator output current is reduced or unstable, but the tightness of the fan belt is not as large as possible. The fan belt Too tight will cause excessive load on the bearing, increased wear, and increased power consumption. At the same time, it will also cause the water pump shaft to bend, the belt will elongate and deform, and its life will be shortened. Therefore, the fan belt should be kept tight and properly adjusted if necessary. Method to check belt tightness: Use fingers or a ruler to press in the middle of the belt with a pressure of 30-50N, and deflection of the belt by 10-20mm is appropriate. Some engines are equipped with two belts, and some engines are equipped with three or four belts. Each pulley system should be on the same plane, and the belt cannot be twisted during installation. If the belt is severely worn or broken, it should be replaced in time. If there are two fan belts, they must be replaced at the same time to avoid uneven tightness and uneven force, which may cause malfunctions.
