Effect of air on diesel generator set
The influence of air on diesel generator sets has many aspects, including air pressure, air humidity, air cleanliness, etc. So what should we pay attention to when diesel generator sets operate in these poor air environments?
The level of air pressure has very strict requirements on diesel generator sets. If the Kaichen diesel generator set is operating under plateau conditions, please note: due to the higher altitude of the plateau, the ambient temperature is lower than that of the plains, and the air on the plateau is thin, so the starting performance of the diesel engine is relatively poor in plateau areas. Difference. Ito diesel generator sets must use a pressurized closed cooling system when operating under plateau conditions. At the same time, the output current of the diesel generator set will change with changes in altitude and decrease as the altitude increases.
Humid air also has a certain impact on diesel generator sets. For generator sets operating in high-humidity environments, heaters should be installed on the diesel generator windings and control boxes to prevent short circuits or insulation damage due to condensation inside the diesel generator windings and control boxes. Note: For engines with different uses and models, due to different requirements for their low-temperature starting performance, the low-temperature starting measures adopted are also different. For engines with high low-temperature starting performance requirements, in order to ensure that they can start smoothly at very low temperatures, it is sometimes necessary to take multiple measures at the same time. Install a glow plug, use an appropriate amount of starting fluid, increase the mixture concentration, assist in starting, and operate under conditions of poor cleanliness. Long-term operation in a dirty and dusty environment will damage parts. Accumulated sludge, dirt and dust can coat parts and make maintenance more difficult. The buildup can contain corrosive compounds and salts that can damage components. Therefore, in order to maintain the longest service life to the greatest extent, the maintenance cycle must be shortened.
Keeping the air in the machine room smooth is beneficial to the diesel generator set without any harm. If the diesel generator set is used indoors, the user must ensure that there is enough fresh air. If the engine room is too tightly sealed, it will lead to poor air circulation, which will not only affect the diesel combustion rate of the diesel engine, but also reduce the cooling effect of the diesel generator set. The inlet air cooling cannot be achieved, and the heat generated by the diesel generator set cannot be discharged. The temperature in the computer room will gradually rise and reach the red alert value, causing malfunctions. Therefore, the computer room can not install windows and use anti-theft nets instead of glass. The height of the windows from the ground should not be too high. This will also affect the diesel generator set. "Breathe" fresh air.
Clean air is also necessary for diesel generator sets. When the diesel generator set is used outdoors, it is easy to inhale dirt or dust and sand. If the diesel generator inhales a large amount of dirty air or inhales dust and floating sand, the power of the diesel engine will decrease. If the diesel generator inhales dirt and other impurities, the insulation between the stator and rotor gaps will be damaged, which will seriously lead to diesel power generation. The machine burned down. Therefore, when using a diesel generator set outdoors, you must ensure the quality of the environment around the unit, or take necessary protective measures to "filter" the air, or use Ito's safety box and rain cover.
