Air Quality and Temperature Influence on Generator

If the generator is used indoors, we have to ensure that he has enough fresh air. If the engine room is sealed too tightly, 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 unit. It will gradually rise and reach the red warning value, which will lead to failure. Therefore, generally do not install windows in the engine room, use anti-theft nets instead of glass, and the height of the windows from the ground should not be too high, which will also affect the “breathing” freshness of the diesel generator.When some customers use diesel generators outdoors, they do not consider the surrounding environment and just use them blindly.

Over time, it is found that the power of the diesel engine is slowly decreasing, but I don’t know why. In fact, this is the power drop of the diesel engine caused by the inhalation of a large amount of dirty air or the inhalation of dust and floating sand by the diesel generator set. If the generator inhales dirt and other magazines, the insulation between the stator and rotor gaps will be damaged, which will seriously lead to power generation. The machine burned out. Therefore, the use of diesel generator sets outdoors must ensure the quality of the surrounding environment, or take necessary protective measures to “filter” the air.

Since the diesel generator works through the diesel engine and converts kinetic energy into electrical energy, a certain amount of heat will be generated during the work process, so a fan water tank is required to cool the generator set. Therefore, the ambient temperature will have a certain impact on the use of diesel generator sets.Normally, the ambient temperature used by the diesel generator is -15°C to 40°C. If it is not within this normal range, it is necessary to consider modifying the accessories of the diesel generator . For example, when the ambient temperature is lower than -15 °C, the generator set should be equipped with a water jacket heater to ensure that the temperature of the diesel generator radiator is within the normal range, so that the generator can be started normally. When the ambient temperature is higher than 40°C, it is necessary to consider replacing the water tank of the generator set, because the normal ambient temperature of the water tank of the diesel generator set is -15°C to 40°C, and the pure copper water tank above 50°C should be replaced at this time. Ensure the normal use of the generator. Do not damage the generator because of this negligence.
