As the altitude rises, diesel generator sets are affected by harsh environments such as low temperature, low pressure, and anoxic ultraviolet rays on the plateau.The diesel generator set's power system, cooling system, starting performance, electrical performance, etc. have been reduced to varying degrees, affecting the normal use of equipment .
1 High temperature causes diesel engine power to decrease
The high temperature environment on the plateau will cause the power performance of diesel generators to decline.The main influencing factors are as follows:
(1) The power drops due to higher temperature;
(2) The cooling capacity of the water tank is reduced, causing the diesel engine to easily overheat.
2 Reduction of intake air charge, resulting in reduced engine power
The role of the air filter is to block or filter out dust and impurities in the intake air to reduce the wear and failure of the main components such as the cylinder liner, piston ring, piston and valve, and prolong the service life of the diesel engine.
The dust density of the air in the desert area is high, the filtering efficiency of the air filter is reduced, the intake air resistance is increased, and the intake air volume is reduced, resulting in a further reduction in power.
3 Impact on startup performance
The temperature in the desert area can be as low as -30 ℃ in winter or at night. The low-temperature environment causes the oil viscosity to increase, the battery capacity to decrease, and the start-up difficult.
4 Impact on unit reliability
The main phenomena are frequent blockage of air filters, severe wear of parts and high thermal load of diesel engines.
5 Anti-aging performance
Highland ultraviolet accelerator units on the surface of rubber, plastic, paint and other polymers age and crack.
6 Impact of plateau environment on electrical performance
The impact of plateau environment on low-voltage electrical products is mainly reflected in temperature rise, insulation performance, connection capacity and breaking capacity, product performance, life, interference with PLC and other aspects.
