Precautions for The Cummins Diesel Generator Sets at Low Temperature

Apr. 20, 2022

When the Cummins diesel generator set is used under the condition of low ambient temperature, there will be certain restrictions. Therefore, the use of Cummins diesel generator set under low temperature conditions should pay attention to some restrictions caused by low temperature conditions. Below, Starlight Power Generation Equipment will briefly introduce some methods when the Cummins generator set is used at low temperature, we hope it will be helpful to everyone.


Cummins genset


1. If the Cummins diesel generator set is parked in the open air, you should pay attention to the weather changes at any time. When the local temperature is lower than -4℃, the cooling water in the cooling water tank of the Cummins diesel engine should be released, because the water at -4℃ The volume change of the water is relatively large, and when the water changes from liquid to solid, the volume expansion can damage the cooling tank radiator.


2. Due to the poor working environment of the Cummins diesel generator set at low temperature, it is necessary to change the air filter element frequently at this time. Due to the extremely high requirements on the air filter element and diesel filter element in cold weather, if it is not replaced in time, it will increase the wear of the engine. Affect the life of the diesel engine.


3. When choosing oil for Cummins diesel generator set at low temperature, try to choose oil with thinner viscosity.


4. When the Cummins diesel generator set is started at low temperature, the temperature of the air inhaled in the cylinder is low, and it is difficult to reach the natural temperature of diesel after the piston compresses the gas. Therefore, Xingguang power generation equipment reminds users to use corresponding auxiliary methods to increase the temperature of the Cummins diesel generator set before starting the Yuchai diesel generator set.


5. After the Cummins genset is started at low temperature, it should first run at low speed for 3-5 minutes, so as to increase the temperature of the Cummins diesel generator set, check the working condition of the lubricating oil, and then put it into normal operation after the inspection is normal. During the operation of the Cummins diesel generator set, it is necessary to minimize the sudden acceleration of the speed or the large operation of the accelerator, otherwise the service life of the valve assembly will be affected for a long time.


6. If the Cummins generator works when the temperature is lower than 0 °C, then after the work of the unit is over, we must release the cooling water from the equipment with water in the unit every day to avoid freezing and cracking; if the equipment has been added If there is antifreeze, don't let it out. We also regularly check the concentration of antifreeze, and prohibit the use of untreated water as engine coolant.


7. When using the Cummins diesel generator set at low temperature, it is necessary to preheat the Cummins diesel generator set first, and then start it after preheating to above 30~40℃.
