Selection Standards for Diesel Generator Sets in Civil Buildings

Information summary:

 Selection of the number of units When using the motor starting capacity to select the capacity of the generator set, the number of generators should not be large, because the increase in the number of units and the small capacity of a single unit may not meet the starting requirements of the motor. Generally, when the capacity is not more than 800kw, it is better to choose a single unit. When the capacity is more than 800kw, two units should be selected, and the physical parameters of the two units should be the same to facilitate the parallel operation of the units. 


Selection Standards for Diesel Generator Sets in Civil Buildings

(1) Selection of the number of units When using the motor starting capacity to select the capacity of the generator set, the number of generators should not be large, because the increase in the number of units and the small capacity of a single unit may not meet the starting requirements of the motor. Generally, when the capacity is not more than 800kw, it is better to choose a single unit. When the capacity is more than 800kw, two units should be selected, and the physical parameters of the two units should be the same to facilitate the parallel operation of the units.  

(2) The choice of other functions The standby emergency generator set for civil buildings should use high-speed diesel generator set and brushless automatic excitation device. The selected unit should be equipped with fast automatic start and automatic power switching devices, and should have the function of three consecutive self-starting. It is not advisable to use compressed air to start, and generally use 24V battery packs as the starting power source.  

How to deal with the layout, ventilation, smoke exhaust and noise of the diesel generator room?

(1) The plane layout of the machine room When choosing the plane position of the machine room, it should be as close as possible to the power distribution room, because it is convenient for wiring, reduces the loss of materials and electric energy, and is also convenient for management. If conditions permit, the computer room is best located on the first floor, which is convenient for ventilation, heat dissipation, and smoke exhaust. However, in high-rise buildings and large and medium-sized commercial buildings, the first floor is usually used as a commercial room. The owner generally does not agree to this plan, and often Set the computer room in the basement. At this time, pay attention to the following points in choosing the location of the computer room:   

(1) The machine room must have one side against the outer wall, so that the equipment is ventilated and smoke exhaust is easier to handle.  

(2) Attention should be paid to the lifting, transportation and maintenance of the unit. Generally, the entrance and exit passage of the parking garage is used as the transportation passage, but if the passage is too small, the position of the lifting hole should be considered.  

(3) Avoid damp places, and do not place them under or next to places with frequent water accumulation such as toilets, bathrooms, pools, etc., to avoid affecting the operation of the unit due to toilet maintenance or floor seepage.

  

(2) The ventilation and heat dissipation diesel engine of the unit, the generator and the exhaust pipe all emit heat during operation, which will increase the temperature of the machine room. A certain increase in temperature will affect the output of the generator. Therefore, measures must be taken to ensure the unit Of cooling. In the case of sufficient air intake and exhaust channels, a closed water circulation and air-cooled integrated unit is generally used. Otherwise, the exhaust fan and radiating pipe can be separated from the main body of the unit and placed separately outdoors, and the water pipe will heat the outdoor heat. The pipe is connected with the diesel engine.  

 

(3) When designing the smoke exhaust pipe system, the following points should be paid attention to:   

(1) Minimize the back pressure of the smoke exhaust system, because the increase in exhaust gas resistance will lead to a decrease in the output of the diesel engine and an increase in temperature rise. Therefore, the shorter and straighter the smoke exhaust pipe is designed, the better.  

(2) The smoke exhaust pipe should be insulated to reduce scalds and reduce heat radiation to increase the temperature of the computer room.  

(3) A muffler should be installed to reduce noise.  

(4) Noise treatment Generally, the selected units in civil buildings are high-speed units, and the noise is relatively large. In order to meet environmental protection requirements, sound-absorbing materials and noise-elimination measures should be installed in the computer room.  

Because the actual conditions of each project are very different, when selecting emergency diesel generator sets, in addition to meeting the requirements of the specification, they should also be set according to the actual situation to achieve satisfactory results.
