China is a vast country with many high-altitude regions in the central and western regions, including Tibet, Qinghai, Yunnan, Guizhou and Sichuan. In remote areas of these provinces and autonomous regions, it is often difficult to reach the power supply load, so diesel generators need to be purchased as regular power sources. Due to the high altitude of the plateau region, the oxygen in the air is relatively thin. People who live on the plains often suffer from altitude sickness, which is characterized by lack of sleep, mild chest tightness, and excessive excitement. Diesel generator sets work by burning diesel fuel for energy conversion, so will the plateau environment be right for diesel generator use?
Diesel generator set due to low pressure, thin air, low oxygen content, low ambient temperature, diesel generator set due to insufficient intake and combustion deterioration, so that the diesel generator can not emit the original regulation of the calibrated power.
Different types of diesel generator sets have different abilities to operate on the plateau. When the generator set is used at the plateau, the power of the non-supercharger decreases by about 6-1O for every 10,000 m increase. Therefore, on the plateau, the supercharger is about 2-5 percent. When the diesel generator set is used for a long time, the oil supply should be appropriately reduced according to the local altitude.
Considering the tendency of fire delay under high altitude conditions, it is generally recommended that the diesel engine supply the diesel engine from the sky to the sky.
According to this year’s experiments, diesel engines used at high altitude can be compensated for by exhaust gas turbocharging. Exhaust gas turbocharging can not only compensate for the lack of power at high altitude, but also improve smog, restore power function and reduce fuel consumption.
With the increase of altitude, the ambient temperature is also lower than that in the plain area, generally 10,000 M per liter, the ambient temperature drops about 0. Because of the thin air on the plateau, around 6 degrees Celsius, the generator starts worse than the plains. In use, the user should adopt the auxiliary start method corresponding to the low temperature start.
Due to the increase of the sea volume, the boiling point of water is reduced, the wind pressure of the cooled air and the quality of the cooled air are reduced, and the heat dissipation per kilowatt per unit time is increased. Therefore, the cooling system cooling conditions are much worse than the plain. In general, open cooling cycles should not be used at high altitudes. Pressurized closed cooling system can be used to improve the boiling point of highland coolant.
Considering the operation economy of high diesel generators, it is generally recommended that non-supercharged diesel engines operate economically, and it is generally recommended that non-supercharged diesel engines advance the oil supply Angle appropriately.
Taking the above factors into consideration, it is necessary to explain the operating environment of the unit to the manufacturer when purchasing the diesel generator, and choose the diesel generator set that can withstand harsh weather conditions and plateau.
