Precautions For Using Diesel Generator Sets In Harsh Environments

Various technical indicators of diesel generator sets are standard data under certain meteorological conditions, such as:

1. Altitude: ≤1000M.

2. Wind speed: The maximum wind speed over the years is 30m/s, the maximum wind speed is 11, and the basic wind pressure is 0.35Kpa. The dominant wind direction is southeast wind in summer and northeast wind in winter.

3. The maximum relative humidity is 100%, and the maximum monthly average relative humidity is 88%.

4. Temperature: The highest average temperature +28.2℃, the lowest average temperature +12.8℃.

5. Precipitation: The maximum annual precipitation is 1970.6 mm, the minimum annual precipitation is 952.9 mm, the maximum daily precipitation is 198.6 mm, and the average annual precipitation is 1308.3 mm.

However, due to the vast territory of China, various natural environments, and the different environments of different industries, diesel generator sets cannot be used in an environment that fully meets the standard conditions. Then when diesel generator sets are in different harsh environments, what should we pay attention to when using it? This article Jiangsu Starlight Electricity Equipments Co.,Ltd. will take you to find out.

1. High-altitude plateau areas.

Diesel generator sets are used in high-altitude plateau areas, especially naturally-aspirated engines. When used in plateau areas, some power is lost due to thin air that cannot burn as much fuel as at sea level. Engines generally lose about 3% of power for every 300m increase in altitude. Therefore, when working in plateau areas, lower power should be used to prevent smoke and excessive fuel consumption.

2. Extremely cold regions.

When using diesel generator sets to operate under extreme cold conditions, auxiliary starting equipment (fuel heaters, oil heaters, water jacket heaters, etc.) need to be added. Fuel heaters or electric heaters are used to remove the cooling water and fuel oil from the cold engine. The lubricating oil heats up the entire engine so that it can be started smoothly. When the temperature of the engine room is not lower than 4°C, install a coolant heater to maintain the temperature of the engine block above 32°C. Install low temperature alarm for generator set. For diesel generator sets that work at ambient temperatures below -18°C, lubricating oil heaters, fuel pipelines and fuel filter heaters are also required to prevent fuel solidification.

Diesel generator sets need to use low-temperature lubricating oil to reduce the viscosity of the lubricating oil to improve the fluidity of the lubricating oil and reduce the internal frictional resistance of the liquid. Utilize high-energy storage batteries to use high-energy storage batteries, such as the current nickel-hydrogen batteries and nickel-cadmium batteries. Pay attention to the heating or heat preservation of the battery. If the temperature in the equipment room drops below 0°C, a battery heater should be equipped. In order to maintain the battery capacity and output power.

3. High humidity

For diesel generator sets working in high humidity, heaters should be installed in the generator windings and control box to prevent short circuit or damage to the insulation due to condensation inside the generator windings and control box. Note: For different purposes and models of engines, the low-temperature starting measures adopted are also different due to different requirements for its low-temperature starting performance. For engines with high requirements for low-temperature starting performance, in order to ensure that they can be started smoothly at very low temperatures, it is sometimes necessary to adopt multiple measures at the same time.

4. Dirty environment and dusty environment.

Install glow plugs and use proper amount of starting fluid to increase the concentration of mixed gas and ether to assist starting. Long-term operation under poor cleanliness conditions will damage parts. The accumulated sludge, dirt, and dust may wrap the parts and make the maintenance of the generator set more difficult. The accumulation will contain corrosive compounds and salts, which can damage parts. Therefore, in order to ensure the service life of the diesel generator set, the user must shorten the maintenance period of the generator set.

The above are some precautions shared by Starlight Power about diesel generator sets working in extremely harsh environments. We hope that users will know.
