How to reduce the noise of diesel generator set as much as possible during the use of the generator set? Reducing the noise of diesel generator sets is a technique.

1. Manufacture of fireproof and soundproof doors

The thickness of the metal frame made of steel plate is about 100mm. The size is determined by the size of the engine room and the size of the diesel generator. The interior is equipped with sound insulation materials, the outside is a metal iron plate, and the sound insulation door and the surrounding metal frame are sealed with soft seals.

Second, the design of the air intake and muffler air duct in the machine room

It is made of steel plate with built-in muffler material, which has the characteristics of light structure and beautiful appearance. The air enters the machine room through the air inlet and muffler air groove. The muffler air groove has the function of blocking noise from being transmitted outside the machine room.

3. Design of exhaust and muffler air ducts in the machine room

The fan of the diesel generator set cools the water tank compulsively, the hot air is discharged from the machine room through the exhaust muffler groove, and the noise also comes out from the muffler air groove. The muffler air groove can effectively reduce the intensity of the noise. The silencer groove is made of steel plate and silencer material.

4. Soundproofing of the engine room of the diesel generator set

According to the specific conditions of the computer room, there are two kinds of structures for the noise reduction system. One is the design of the noise reduction wall in the computer room, and the other is the perforated plate on the inner wall surface of the computer room to make the noise reduction wall.

Fifth, the silencer production of unit exhaust system

In order to prevent the exhaust pipe and the indoor muffler from releasing heat in the machine room, the smoke exhaust pipe and the indoor muffler are wrapped with fireproof materials to reduce the heat emission of the unit to the machine room. In order to improve the noise reduction effect of the exhaust gas, secondary mute must be used. Under normal circumstances, the first-level mute diesel generator set has been installed, and the second-level mute device uses anti-mute device to make the sound insulation effect more obvious.
