How can I do a good job of noise isolation for Cummins diesel generators?

The use of Cummins diesel generator sets will generate noise, so do you know how to do a good job of noise isolation treatment of Cummins diesel generator sets? The following introduces you in detail:


I. Sound insulation windows for diesel generator rooms:

The original window was changed to a sound insulation window with a size of 900mm × 1500mm. The window core was composed of double-layer sealed glass with a thickness of 50-90mm in the middle.


Installation of sound insulation door in diesel generator room

In order to facilitate dust removal and equipment maintenance, the original wooden door was changed to a sound insulation door. The specific method is: fill super thick glass wool or rock wool inside, and enclose 2.5mm thick perforated aluminum plate. Reduce the noise transmitted from the equipment room to the outside.


Third, human and machine separation

Separate the duty room from the generator room, and install sound insulation windows on the inside wall of the duty room to facilitate the observation of generator operation. There is an entrance between the computer room and the duty room, and a sound insulation door is installed in the door opening to reduce the noise transmitted from the computer room to the duty room, and it is also easy to operate.


Fourth, the inner wall of the diesel generator room is properly sound-absorbing:

The noise reduction engineering team of Cummins Diesel Generator Company can modify the original interior wall of the engine room, and make rock wool into a rectangular sound absorption board of a certain specification, fixed with a galvanized steel mesh cover, and arrange the sound absorption board on the wall Space interface. When the sound-absorbing board is mounted on the wall, its bottom edge is 100 mm from the inner wall surface, its top edge is 250 mm, and its plate height is 3500 mm. In this way, high-frequency sound waves are attenuated, and an air layer is provided behind the sound absorption plate, so that the low-frequency sound absorption coefficient is improved.
