Ventilation design principle of diesel generator room
The ventilation system of the equipment room has a direct and important influence on the output power, fuel consumption rate, hot airflow emission and service life of the diesel generator set.
运转时，一方面会将部分清新空气吸入燃烧室，使其与燃油均匀混合于燃烧室燃烧作功，驱动整台柴油发电机组持续运转；同时，柴油发电机组运转时所产生的大量热量必须及时散发出机房，这就会消耗大量的清凉空气。 When the diesel generator set is running, on the one hand, part of the fresh air is drawn into the combustion chamber, so that it is evenly mixed with the fuel in the combustion chamber for combustion work, which drives the entire diesel generator set to continue to run; at the same time, a large amount of The heat must be dissipated in the machine room in time, which consumes a lot of cool air.
Therefore, in addition to the standard diesel generator set itself must have good circulating water cooling or oil cooling structure, the cooling and ventilation system of the engine room is also very important and indispensable. It is necessary to ensure that sufficient air flows through the engine room to supplement the consumption. The air used for the combustion of the engine and the large amount of heat emitted by the diesel generator set are discharged out of the engine room through the radiator core, so that the temperature in the engine room is as close as possible to the ambient temperature and the temperature of the diesel generator body is kept in the normal working range. When the conditions of the equipment room fail to meet the required net area of the intake and exhaust vents, forced intake and exhaust methods must be considered to ensure the normal combustion and cooling requirements of the diesel generator set.
In buildings, vents are usually equipped with shutters and metal protective net curtains. When calculating the size of the air inlet, the invalid area occupied by shutters and metal net curtains must be considered. In the winter, when the diesel generator set is used for standby operation, the diesel generator set is only operated occasionally, and most of the time it is in a standby shutdown state. At this time, the proper temperature should be maintained in the engine room to avoid affecting the normal starting ability of the diesel generator set or freezing the cooling water, which may cause damage to the diesel generator set. This requires that all ventilation openings in the machine room must be adjustable so that the unit can be automatically or manually closed when the unit is deactivated. At the same time, it is recommended that the diesel generator set be equipped with a matching water jacket heater and keep it in normal working condition at all times.
The above are the precautions for the diesel generator room provided by Jiangsu Reed Power Equipment Co., Ltd. The company mainly produces Cummins generators, Yuchai generators, Volvo generators, Shangchai generators, imported generators, domestic generators . kardio.cn Service URL: kardio.cn
