1. The entrance of the diesel generator room should be silenced
Each generator room has at least one or more out of the entrance, from the Angle of noise reduction, the door of the machine room should not be set up too much, in general, set up a door, a small door, the area as far as possible not more than 3 square meters, the structure of the metal frame, the interior is equipped with high strength sound insulation material, the external metal plate, noise reduction door and wall and door frame up and down closely
2. The inlet system of diesel generator set is silenced
Because the diesel generator set must be energetic enough to maintain normal operation when it is working, the intake system of the general generator room should be set opposite the fan exhaust outlet of the generator set. According to our experience, the air inlet is forced into the generator room, and the air inlet is pumped into the generator room by the blower through the silencer air chute.
3, diesel generator exhaust system noise reduction
Most diesel generators are cooled by tank fans. The heat from the radiator of the tank must be discharged out of the machine room. In order to avoid noise from the generator room, the exhaust system must be set up to eliminate exhaust noise.
4. Noise suppression of diesel exhaust system outside diesel generator room:
There is still a high noise outside the engine room after the exhaust air is silenced by the exhaust air trough. The exhaust air must be silenced by the silenced air trough set outside the engine room, so as to reduce the noise to a minimum. The silenced air trough is external to the brick wall structure and internal to the sound-absorbing board.
5, diesel exhaust noise reduction system
The exhaust gas emitted by the diesel generator produces a certain noise. A muffler box can be added in the exhaust gas emission system of the generator set. At the same time, the exhaust muffler pipe is wrapped with fireproof rock wool material, which can not only reduce the heat of the unit to the machine room, but also reduce the working vibration of the unit, so as to achieve the purpose of noise attenuation.
