How to operate the diesel generator unit in the cold high altitude

1.Diesel generators组Under the cold weather conditions
Using auxiliary boot device (fuel heater, oil heater, water jacket heater, etc.) utilizes a fuel heater or electric heater, heats cooling water, fuel, lubricating oil, and heat the entire engine so that Start smoothly.
When the equipment room temperature is not less than 4 ° C, the mounting of the coolant heater allows the engine block to maintain the temperature above 32 ° C. Install the low temperature alarm of the generator set.
Workaround: Heating with intake air preheater
The mixture (or air) that enters the cylinder is heated with the intake preheater (electrothermal preheating or flame preheating), thereby increasing the compression end point temperature, and improving the fire condition. The electrothermal preheating method is to install the electric hew plug or electric heating wire in the intake pipe, directly heat intake, it does not consume oxygen in the air, and does not pollute the intake, but it consumes the battery of the battery.
For generators operating at ambient temperature below -18 °, lubricating oil heaters, fuel pipes, and fuel cleaners are also required to prevent fuel curing. The oil heaters are mounted on the engine oil pan. It heated the oil in the oil pan, which is convenient for diesel engines to start at low temperatures. It is recommended to use -10 # ~ -35 # light diesel.
2. Use of high altitude plateau
Generator sets of engine, especially natural intake engines, when used in the plateau area, due to air thin can not be burned so much fuel, for natural intake engine, general altitude The increase of 300 m power loss is about 3%, so at the high work of the plateau, lower power should be used to prevent excessive fuel consumption.
Workaround: use low temperature lubricant
Use low-temperature lubricating oil to reduce lubricating oil viscosity to improve the fluidity of the lubricant and reduce the internal friction resistance of the liquid.
High energy battery
High-energy batteries, such as current nickel-hydrogen batteries and nickel-cadmium batteries. Pay attention to the heating or heating of the battery, if the temperature of the room is reduced to 0 ° C, the battery heater should be equipped. To maintain the capacity and output power of the battery.
