Today we will briefly introduce how to deal with the situation where the fan belt of a diesel generator set is loose, and what else do you want to know about it.

The adjustment method of the generator fan belt: Use 30-50 tons of force to gently press or pull up in the middle of the drive belt, so that the drive belt is 15-20 millimeters away from the original position, and the tightness of the drive belt is considered normal. Otherwise, adjustment should be made.The method can be divided into different structures: it is structured with a tension wheel.Loosen the fixed nut, turn the adjusting screw, move the tension wheel up and down to achieve the desired tightness;The fan and the generator are driven by the same transmission belt, the generator support frame can be moved, and the belt wheel part can be changed to achieve the desired tension.The belt wheel is composed of two halves, first loosen the fixing bolt, then rotate the adjustable half of the belt wheel, thereby changing the width of the belt wheel groove, and thus adjusting the V-belt to achieve the desired tension.

The fundamental cause of the looseness of the diesel generator set fan belt: Firstly, it may be caused by aging, secondly, it may be caused by incorrect model specifications, and finally, it may be caused by the belt wheel spacing offset. These three factors are primarily due to aging.If the fan belt of the diesel generator set becomes loose, it will greatly affect the air flow, and the natural balance of supply and demand of the cooling air flow of the diesel generator set is not enough, which will lead to the rise of the whole machine temperature, resulting in a lot of damage.

The belt will become loose and produce a "squeaking" abnormal sound after running for a period of time.During the process with abnormal noise, try to expand the inspection as much as possible.If there were no cracks, it would just need to be adjusted for tightness.If it cracks, the belt and tension wheel must be replaced.Since it has cracked, tightening the belt further will cause the belt to tear.After the belt broke, the diesel engine couldn't run normally.
