The use of generator sets under harsh environmental conditions is mainly due to the impact of environmental factors. Some measures and methods must be adopted in high-altitude plateau areas and under cold weather conditions. The following are the special environmental conditions. A comprehensive introduction to the usage method:
1. Use in high altitude plateau areas
Engines supporting generator sets, especially naturally-aspirated
engines, when used in plateau areas, lose some power due to thin air that cannot burn as much fuel as at sea level. For naturally-aspirated engines, generally every altitude is Increasing 300m power loss is about 3%, so when working on the plateau, lower power should be used to prevent smoke and excessive gas consumption.
2. Working in extreme cold weather conditions
Add auxiliary starting equipment (oil heater, water jacket heater, etc.)
The electric heater is used to heat the cooling water and lubricating oil of the cold engine to heat up the entire engine so that it can be started smoothly. To
When the temperature in the engine room is lower than 4°C, install a coolant heater to maintain the temperature of the engine block above 32°C.
(1) Install low temperature alarm for generator set.
For generating sets that work at ambient temperatures below -18°C, a lubricating oil heater is also required to prevent the lubricating oil from solidifying. The oil heater is installed on the engine oil pan. It heats the oil in the oil pan, facilitating the engine to start at low temperatures. ...
(2) Use low-temperature lubricating oil
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 friction resistance of the liquid. To
(3) Utilize high-energy batteries
Use high-energy batteries, such as 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. For the generator set working in high humidity, the generator winding and control box should be installed with heaters to prevent the generator winding and control box from causing short circuit or destroying the insulation due to condensation.
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:
(1) Install the glow plug
(2) Use appropriate amount of starting fluid
(3) Increase the concentration of mixed gas
(4) Ether assisted start
4. Work under poor cleanliness conditions
Long-term operation in a dirty and dusty environment will damage the parts. Accumulated sludge, dirt, and dust may coat parts and make maintenance more difficult. The accumulation will contain corrosive compounds and salts, which can damage parts. Therefore, the maintenance cycle must be shortened in order to maintain the longest service life.
5. Use of gas generator sets in other geographical environments
In addition to making outstanding contributions to enterprises and institutions, gas generators have special effects and significance when used in other special environments.
(1) Develop power supply in border areas
The remote areas of our country have abundant resources, but some are far away from the power supply network, and the development of modern technology must have sufficient power supply without exception. Gas generator equipment is the best choice that can quickly meet this requirement. Because of its low investment, fast construction, and self-contained network power supply, gas generators have been widely used in the development of remote areas in many countries in recent years.
(2) Meet the electricity demand in desert areas
In order to meet the needs of oil and natural gas exploration and development in the hinterland of the desert, the use of gas generator sets in desert areas will increase greatly along with desert development.
(3)Power guarantee in the tourism development zone, etc.
