How to reduce noise in the generator room?

Diesel used indoors generator sets are generally placed in a special computer room. In order not to cause noise pollution to the surrounding environment, noise reduction is required. According to Haixing Dynamics' summary, there are three common methods.

The noise reduction in the computer room requires the processing of the causes of noise separately, and the following methods are mainly used:

1. Inlet and exhaust noise reduction: The air inlet and exhaust passages in the computer room are respectively soundproofed walls, and soundproofing tapes are installed in the air inlet and exhaust passages. There is a distance in the channel for buffering, which can reduce the intensity of the sound source radiating from the computer room to the outside.

2. Control mechanical noise: The top and surrounding walls of the computer room are laid with high sound absorption and sound insulation materials, mainly used to remove indoor reverb and reduce the sound energy density and reflection intensity in the computer room. To prevent noise from radiating outward through the door, arson soundproof iron door is installed.

3. Control smoke exhaust noise: The smoke exhaust system installs a secondary silencer on the basis of the original primary silencer to ensure the corresponding control of the unit's smoke exhaust noise. If the length of the smoke exhaust pipe exceeds 10 meters, the pipe diameter must 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 processing, the noise of the generator set in the computer room can meet the user's requirements outdoors.

In addition, everyone should also pay attention to the abnormal sound of the generator set is sometimes a signal of failure. For example, the continuous metal hitting sound is the piston hitting the cylinder head; the sound of drinking or 'hissing' may represent the leakage of the piston ring. Some tiny noises frequently appear, so everyone should start paying attention and analyzing the source.
