The Use Of Diesel Generator Set Under Severe Conditions

Mar. 21, 2022

The use of diesel generator set in harsh environmental conditions is mainly due to the influence of environmental factors, some measures and means that must be adopted in high-altitude plateau areas and in cold weather conditions. The following is a comprehensive introduction to the use methods in various special environments.

 

Environmental factors: high altitude plateau areas use the engine matched with generator set, especially the naturally aspirated engine. When used in plateau areas, due to the thin air, it can not burn so much fuel as at sea level and lose some power. For naturally aspirated engines, the power loss is about 3% for every 300m increase in altitude. Therefore, when working on the plateau, lower power should be used to prevent smoke and excessive fuel consumption.

When working in cold weather, add auxiliary starting equipment (fuel heater, oil heater, water jacket heater, etc.), and use fuel heater or electric heater to heat the cooling water, fuel and lubricating oil of cold engine, so as to raise the temperature of the whole engine, so as to start smoothly. When the temperature of the machine room is not lower than 4 ° C, install the coolant heater to keep the temperature of the engine block above 32 ° C. Installation of low temperature generator set alarm. For the generator set that will operate under the ambient temperature below - 18 °, lubricating oil heater, fuel pipe and fuel filter heater are also required to prevent fuel solidification. The oil heater is mounted on the engine oil pan. Heat the oil in the oil pan to facilitate the diesel engine to start at low temperature. It is recommended to use #- 10 ~ #- 35 light diesel oil.

 

Heat with intake air preheater. The mixture (or air) entering the cylinder is heated by the intake preheater (electric heating preheating or flame preheating), so as to increase the compression end temperature and improve the ignition conditions. The electric heating preheating method is to install an electric heating plug or electric heating wire in the intake pipe to directly heat the intake air. It does not consume oxygen in the air or pollute the intake air, but it consumes the electric energy of the battery.

 

Use low temperature lubricating oil. Low temperature lubricating oil is used to reduce the viscosity of lubricating oil, so as to improve the fluidity of lubricating oil and reduce the internal friction resistance of liquid. High energy batteries are used, such as current nickel hydrogen batteries and nickel cadmium batteries. Pay attention to the heating or thermal insulation of the battery. If the temperature of the machine room will drop below 0 ℃, the battery heater shall be equipped to maintain the capacity and output power of the battery.

 

Note: for different purposes and models of engines, due to different requirements for its low-temperature starting performance, the low-temperature starting measures adopted are also different. For the engine with high requirements for low-temperature starting performance, in order to ensure that it can start smoothly at very low temperature, sometimes a variety of measures need to be taken at the same time. Install the glow plug and use an appropriate amount of starting fluid to increase the mixture concentration. Transport damaged parts in a dirty and dusty environment. Accumulated sludge, dirt and dust may wrap the parts and make maintenance more difficult. Salt compounds can accumulate and damage parts. Therefore, in order to maintain the longest service life to the greatest extent, the maintenance cycle of generator must be shortened.
