How to reduce noise in the generator room?

Diesel for indoor useGenerator setThey are generally placed in a dedicated computer room. In order not to bring noise pollution to the surrounding environment, the computer room needs to be noise-reduced. According to Haixing Dynamics’ summary, there are three commonly used methods.

Noise reduction in the computer room needs to deal with the causes of noise separately. The main methods are as follows:

1. Air intake and exhaust noise reduction: The air inlet channel and exhaust channel of the computer room are made of soundproof walls respectively, and silencers are installed in the air inlet channel and exhaust channel. There is a distance within the channel for buffering, which reduces the intensity of the sound source radiating outward from the computer room.

2. Control mechanical noise: Lay absorbing and sound insulation materials with high sound absorption coefficients on the top and surrounding walls of the computer room, mainly to remove indoor reverberation and reduce the sound energy density and reflection intensity in the computer room. In order to prevent noise from radiating outward through the door, fire and soundproof iron doors are installed.

3. Control smoke exhaust noise: The smoke exhaust system installs a second-level silencer on the basis of the original first-level silencer, which can ensure the corresponding control of the smoke exhaust noise of the unit. If the length of the exhaust pipe exceeds 10 meters, the pipe diameter must be enlarged to reduce the exhaust back pressure of the generator set. The above processing can improve the noise and back pressure of the generator set. Through noise reduction processing, the noise of the generator set in the machine room can meet the user's requirements outdoors.

In addition, everyone should also pay attention to the fact that abnormal sounds from the generator set are sometimes signals of malfunctions. For example, the continuous metal knocking sound of 'tat-tat-tat' is the piston top hitting the cylinder head; 'squeaking' or 'hissing' The hissing sound may represent air leakage from the piston ring. If some small noises appear frequently, everyone should start to pay attention and analyze the source.
