What are the effects of fan belt tension on diesel generator sets?

The correct adjustment of the fan belt of the diesel engine directly affects the normal operation of the diesel generator set. Generally speaking, the tightness of the fan belt is to press the belt strip with the thumb, and the pressure is about 10KG. If there is a pressing amount of about 15mm, it can be judged that the tension of the belt is appropriate.

 

The so-called "fan belt" usually refers to the three pulleys of the diesel engine fan, crankshaft and generator of the diesel generator set using a common set of belts. The correct adjustment of the fan belt of the diesel engine directly affects the normal operation of the diesel generator set.

 

The fan belt is too tight, causing the load on the generator and water pump pulley to increase. It will reduce the bearing radial clearance of the water pump bearing and the generator bearing, resulting in premature damage or burning of the water pump bearing and the generator bearing. At the same time, because the belt is too tight, the friction increases, the wear increases, the working temperature of the belt increases, and the service life of the belt is greatly reduced.

 

If the fan belt is too loose, the generator speed will not be enough, and the power generation will be reduced. At the same time, because the generator and water pump share a set of belts coaxially, the pump speed will not be enough, resulting in insufficient supply of circulating cooling water for the diesel engine. The heat dissipation of the water tank is weakened, and the working temperature of the diesel generator set is increased.

 

Generally speaking, the tightness of the fan belt is to press the belt strip with the thumb, and the pressure is about 10KG. If there is a pressing amount of about 15mm, it can be judged that the belt tension is appropriate.
