When a silent diesel generator set is running at 1500rpm, it will generate 105 decibels of noise at a distance of one meter from the generator set. In order to prevent the noise from spreading out of the machine room, the noise reduction project should include the following links.
1. Muffling of the entrance and exit of the computer room:
Each computer room has at least one entrance and exit. From the perspective of noise reduction, the doors of the computer room should not be set too much. Generally, one large door and one small door should be set up, as far as possible, no more than 3 square meters. The structure is made of metal. It is equipped with high-strength sound insulation materials, and the exterior is made of metal iron plates. The sound-absorbing door is closely matched with the wall and the door frame.
2. Muffling of diesel engine air intake system:
When the diesel engine is working, there must be enough air intake to maintain normal operation. Generally, the air intake system should be set directly opposite the air outlet of the unit fan. According to our experience, the air intake adopts the forced air intake method, and the intake air is silenced. The air duct is drawn into the machine room by the blower.
3. Diesel engine exhaust system silencer:
The diesel engine is cooled by the water tank fan system, and the radiator of the water tank must be exhausted out of the machine room. In order to prevent the noise from being transmitted out of the machine room, the exhaust system must be equipped with exhaust and silencer air slots.
4. Silencer for the exhaust system of the diesel engine outside the machine room:
The exhaust air of the diesel engine still has high noise outside the machine room after the noise is eliminated by the exhaust gas silencing air slot. , The outside of the sound-absorbing air duct is a brick wall structure, and the inside is a sound-absorbing panel.
5. Diesel engine exhaust muffler system:
The exhaust gas emitted by the diesel engine produces a certain amount of noise. We add a silencer box to the exhaust gas discharge system of the unit. At the same time, the exhaust silencer pipes are wrapped with fireproof rock wool materials, which can reduce the heat of the unit from being emitted into the machine room, and It can reduce the working vibration of the unit, so as to achieve the purpose of attenuating noise.
