What are the reasons for the high temperature of diesel generators?

In the process of using diesel generators, we must pay special attention to these. When the diesel engine temperature is too high, it will usually cause the coolant in the radiator to boil, the power of the diesel engine to decrease, the viscosity of the lubricant to decrease, the friction between the diesel engine parts to increase, and even cause the diesel engine to pull. Cylinder, cylinder pad burning and other serious failures.

The reason for the high temperature of diesel generators is as follows:

1, long-term overload operation

If the diesel engine is overloaded for a long time, the fuel consumption will increase and the heat load will increase. As a result, the water temperature will be too high. For this reason, long-term overload operations should be avoided.

2, lack of coolant

If there is a lack of coolant in the diesel engine cooling system, it will affect the cooling effect of the diesel engine and cause the diesel engine to become hot. In this regard, the inventory of coolant in radiators and expansion tanks should always be checked. When the level is low, it should be replenished promptly.

3, poor circulation of coolant

The insufficient opening of the thermostat will reduce the cooling capacity of the diesel engine cooling system during the large cycle. If the diesel engine is at a high temperature, the thermostat can be placed in water for heating inspection. The opening distance of the thermostat is 8 to 10 mm.

Reminder: Poor performance of the pump will result in reduced coolant flow, resulting in high engine temperatures.

4, heat sink mutual interference (construction machinery)

If the hydraulic oil radiator and the water radiator are placed one after the other, when the temperature of the hydraulic oil is too high, the temperature of the cold air on the inlet side of the water radiator is bound to be high, which will affect the heat dissipation of the water radiator. In this regard, the thermal conditions of the hydraulic system should be overhauled to reduce the effect of the hydraulic oil radiator on the poor heat dissipation of the diesel water radiator.

5, radiator attached to the surface of debris

The attachment of foreign matter on the surface of the heat sink will reduce the heat dissipation area of ​​the heat sink and reduce the windward area of ​​the heat sink, resulting in a reduction in the heat dissipation capacity of the heat sink, resulting in high temperature of the diesel engine 6, too loose fan belt or deformation of the fan

If the fan belt is too loose, the rotation speed of the fan may be reduced, resulting in the radiator not being able to exert its own heat dissipation capability, resulting in an excessive temperature of the diesel engine. In addition, the distortion of the fan can also result in the heat sink's ability to dissipate heat. In this regard, you should periodically check if the diesel fan belt is loose and if the fan shape is abnormal.
