Cummins Generator Set Preheating Mechanism Warms Up Slowly

Mar. 02, 2023

After the cold start or operation of Cummins generator unit, the temperature is difficult to rise to the normal operating temperature range. The overcooling of Cummins generator unit is mainly caused by the poor technical status of the unit insulation system and thermostat used in cold seasons or regions.

Reasons for slow warming of the preheating device of Cummins generator set

1. The thermostat valve is not closed tightly, and the Cummins generator unit warms up slowly after cold start, and stays cold for a long time, especially in winter.

2. The thermal insulation mechanism has poor operation performance and has lost the thermal insulation function of the radiator. The cold air flowing through the radiator and the diesel generator cannot increase or decrease with the need of the thermal condition of the Cummins generator set, making the Cummins generator set supercooled.

3. The fan with clutch lost the function of adjusting the fan speed due to damage, resulting in excessive exhaust volume and overcooling of Cummins generator unit.

Diagnosis and elimination of slow warming of the preheating mechanism of Cummins generator set

1. First, check whether the thermal insulation system in front of the radiator of Cummins generator unit works well. If it is not good, it should be adjusted or repaired to make the shutter operate freely and adjust flexibly with the temperature of Cummins generator set.

2. Remove the damage of the silicone clutch fan.

3. Check whether the operation performance of the thermostat of Cummins generator unit is good according to the inspection scheme. If the main valve cannot be closed, replace it.
