Precautions for Diesel Generator Sets Under Low Pressure Conditions

What do you think diesel generator sets should pay attention to when the pressure is too low? When operating in a state where the temperature of the cooling water and engine oil is too low, during the operation of the diesel generator set, the temperature of the cooling water is too low, and the temperature of the cylinder wall decreases accordingly. The water vapor generated by combustion condenses into water droplets, which come into contact with the exhaust gas to form acidic substances and adhere to the cylinder wall, causing corrosion and wear. Practice has proven that when diesel generator sets are often used at cooling water temperatures of 40 ℃ to 50 ℃, their parts wear and tear is several times greater than when operating at normal operating temperatures (85 ℃ to 95 ℃).

At this point, when the water temperature is too low, the temperature inside the cylinder is low, and the ignition delay period of the diesel generator set is extended. Once ignited, the pressure rapidly increases, and the diesel generator set has rough fuel, which can easily cause mechanical damage to the components. The diesel generator set has been operating at low cooling water temperatures for a long time, resulting in a large gap between the piston and the cylinder liner, causing knocking and vibration, resulting in cavitation of the cylinder liner. The oil temperature is too low, the viscosity of the oil is high, and the fluidity is poor. The insufficient amount of oil in the lubrication area leads to poor lubrication, increased wear of the friction pair, and shortened the service life of the diesel generator set.

If the oil pressure is too low during operation, the lubrication system will not be able to perform normal oil circulation and pressure lubrication, and the lubrication parts will not receive sufficient oil. Therefore, during the operation of the diesel generator set, it is necessary to pay attention to the condition of the oil pressure gauge or oil pressure indicator light. If the oil pressure is found to be lower than the specified pressure, the machine should be stopped immediately, and the problem should be resolved before continuing driving.
