Summer high-altitude truck fan belt should be replaced

The aerial car fan belt is a belt driven by the crankshaft. Its main purpose is to drive the engine fan and the water pump. The inspection and adjustment of the fan belt tightness: The fan belt tightness is too small, not only affects the cooling air volume but also makes the engine work load increase. Large, but also due to the occurrence of slipping accelerated belt wear. If the belt tightness is too large, it will accelerate the wear of water pump bearings, generator bearings. Therefore, in use should check the tightness of the belt, if necessary, should be given to adjust. Such as Does not meet the regulations, can be adjusted by changing the position of the generator and the adjusting arm.

In the summer, some high-altitude truck drivers think that raising the tightness of the fan belt can improve the cooling effect of the engine. Therefore, the tightness of the fan belt is constantly increased, causing the fan belt to become tight. It is not true that this is not the case. The belt should be kept tightly and tightly, because over-tightening will lead to excessive bearing load, increased wear and tear, increased power consumption, and will also cause the water pump shaft to bend, the belt is elongated and deformed, and the service life is shortened.

In addition, the manufacturers of high-altitude vehicles also informed that if the fan belt slips and sounds abnormally, it will occur when the engine is idling and disappears in the engine at high speeds. This will have little impact on the normal operation of the vehicle and can be eliminated; for example, the noise in the engine and the high speed If it happens, it should be eliminated and replaced with a new fan belt. In addition, the replacement cycle of imported V-belts is generally replaced every 100,000 km; the replacement cycle of domestic V-belts is generally every 40,000 kilometers. Change once.
