Diesel generator sets used indoors are generally placed in specialized computer rooms. In order to avoid noise pollution to the surrounding environment, noise reduction measures need to be taken in the computer rooms. According to the summary of Haixing Power, there are three commonly used methods.

 

Noise reduction in computer rooms requires separate treatment of the causes of noise generation, mainly through the following methods:

 

1. Air intake and exhaust noise reduction: The air intake and exhaust channels in the computer room are respectively equipped with soundproof walls, and soundproof panels are installed inside the air intake and exhaust channels. There is a distance within the channel for buffering, which can reduce the intensity of sound source radiation from the inside out of the computer room.　　

   2. Control mechanical noise: Install high sound absorption and insulation materials on the top and surrounding walls of the computer room, mainly used to eliminate indoor reverberation, reduce sound energy density and reflection intensity in the computer room. To prevent noise from radiating outwards through the main entrance, a fire-resistant soundproof iron door is installed.

 

3. Control smoke exhaust noise: The smoke exhaust system is equipped with a specially designed secondary muffler on top of the original primary muffler, which can ensure effective control of smoke exhaust noise in the unit. If the length of the smoke exhaust pipe exceeds 10 meters, the pipe diameter should be increased to reduce the exhaust back pressure of the generator set. The above treatment can improve the noise and back pressure of the generator set. Through noise reduction treatment, 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 noise from the generator set is sometimes a signal of malfunction, such as the continuous metal tapping sound of "da da da", which is the piston top hitting the cylinder head; The sound of "drinking" or "hissing" may indicate air leakage in the piston ring, and some small noises frequently appear. It is important to start paying attention to and analyzing the source.
