Introduction of Large Gasoline Generators in Harsh Environment

Using large gasoline generators under harsh environmental conditions

The use of large-scale gasoline generators under harsh environmental conditions is mainly due to environmental factors, some measures and measures that must be adopted in high-altitude plateau areas and under cold climate conditions. A description of the use of a special environment:

High altitude plateau

Large-scale gasoline generators are used in high-altitude plateau areas, especially when natural gas engines are used in high altitude areas. Since the air is thin, they can't burn as much fuel as at sea level and lose some power. For natural intake The engine, which generally loses about 3% of the power per 300 meters of elevation, should use lower power to prevent excessive smoke and fuel consumption when the plateau does work.

Very cold weather conditions

When using the generator set in very cold weather conditions, auxiliary starting equipment (fuel heaters, oil heaters, water jacket heaters, etc.) must be used to use the fuel heater or electric heater to cool the engine's cooling water and fuel, Lubricating oil heats up the entire engine so that it can start smoothly. When the room temperature is not lower than 4°C, install the coolant heater so that the engine block maintains the temperature above 32°C. Install genset low temperature alarm. For generator sets that operate at ambient temperatures below -18°, lube heaters, fuel lines, and fuel filter heaters are also required to prevent fuel curing.

The oil heater is mounted on the engine oil pan of the generator set. It heats the oil in the oil pan to facilitate the start of the diesel engine at low temperatures. It is recommended to use -10#--35# light diesel oil. The intake air preheater heats the intake air preheater (electric heating preheating or flame preheating) to heat the mixture (or air) entering the cylinder, thereby increasing the compression end temperature and improving the ignition conditions. The electric preheating method is to install a glow plug or electric heating wire in the air intake pipe to directly heat the air intake. It does not consume the oxygen in the air nor pollute the air intake, but it consumes the electric energy of the battery.

Large gasoline generators use low-temperature lubricating oils to reduce the viscosity of lubricating oils to increase the fluidity of the lubricating oil and reduce the internal frictional resistance of the liquid. The use of high-energy batteries using high-energy batteries, such as the current nickel-metal hydride batteries and nickel-cadmium batteries. Pay attention to the heating or heating of the battery. If the temperature in the equipment room drops below 0°C, a battery heater should be equipped. To maintain the battery capacity and output power.

High humidity occasions

For large gasoline generators operating in high humidity applications, the generator windings and the control box should be equipped with heaters to prevent the generator windings and the inside of the control box from causing short circuits or damaging insulation due to condensation. Note: For different uses and models of engine, due to its different low temperature starting performance requirements, the low temperature starting measures used are also different. For engines with high requirements for low-temperature starting performance, it is sometimes necessary to adopt multiple measures at the same time in order to ensure smooth starting at very low temperatures.

Dirty environment and dusty environment

Installation of glow plugs Use proper amount of starter fluid to increase the concentration of the mixture B. Assisted start-up â–¡ Operate in poor cleanliness conditions Long-term operation in dirty environments and dusty environments can damage components. Stacked sludge, dirt, and dust may encase parts and make it more difficult to maintain the generator set. Accumulation can contain corrosive compounds and salts that can damage parts. Therefore, to maintain a long service life to a great extent, the maintenance period of the generator set must be shortened.
