How to correctly use and maintain a generator in a hostile environment?

The use of generators in harsh environmental conditions, mainly due to the impact of environmental factors in plateau area of high altitude and cold climate at the end of operation must use some measures and means, following the use of a variety of special environment for a comprehensive introduction:

environmental factor

1, the use of high-altitude high-altitude areas

Turbine engine, especially when the naturally aspirated engine used in plateau area, due to the thin air at sea level did not like so much fuel combustion and some loss of power, the naturally aspirated engine, the general elevation of every 300m increase the power loss of about 3%, so in the plateau indeed work, should be used low power to prevent excessive smoke and fuel consumption.

2. Work under extreme cold weather conditions

Additional auxiliary starting equipment (fuel heater, oil heater, water heater, etc.)

The cooling water and fuel oil and lubricating oil of the cold engine are heated by using a fuel heater or an electric heater, so that the whole engine is heated up so as to start smoothly.

When the engine room temperature is not less than 4 degrees C, install the coolant heater to keep the engine cylinder temperature above 32 degrees C.

Install low temperature alarm for generator set.

The generator will be reduced to 18 O ~ the ambient temperature, also need lubricating oil heater, fuel pipe and fuel filter heater to prevent fuel curing. The oil heater is mounted on the engine oil tray. It heats the oil in the oil pan to facilitate the starting of the diesel engine at low temperature.

It is recommended to use -10 ~ -35 light diesel oil.

Heat up with an intake air heater

Heating the mixture (or air) into the cylinder by means of an intake preheater (electrothermal preheating or flame preheating) to increase the temperature at the end of the compression and to improve the ignition conditions. The electrothermal preheating method is that an electric heating plug or an electric heating wire is arranged in the air inlet pipe to directly heat the air inlet. The utility model does not consume the oxygen in the air and does not pollute the air intake, but it consumes the electric energy of the accumulator.

Use low temperature lubricating oil

Use low temperature lubricating oil to reduce the viscosity of lubricating oil to improve the flow of lubricating oil and reduce the internal friction resistance of liquids.

High energy storage battery

Using high energy batteries, such as the current nickel hydrogen batteries and nickel cadmium batteries. Note that the battery heating or heating insulation, and if the room temperature will be below 0 degrees, should be equipped with battery heaters. To maintain battery capacity and output power.

The generator winding and control box shall be equipped with heaters to prevent the generator winding and the inside of the control box from shorting or damaging the insulation when the generator is working at high humidity.

Note: for different uses and types of engines, the low temperature starting measures are different due to their low temperature starting performance requirements. For engine with low temperature starting performance, it is necessary to adopt many measures at the same time to ensure that it can start smoothly at very low temperature.

Install the electric plug

Use proper starting fluid

Raise gas mixture concentration

Ether assisted priming

3, in the poor cleanliness of the operation

Running in dirty environments and dusty environments can damage parts. Accumulated sludge, dirt, and dust may wrap up parts and make maintenance difficult. Deposits contain corrosive compounds and salts that can damage parts. As a result, maintenance cycles must be shortened for maximum maintenance.
