Noise control measures: The noise of diesel generator sets is mainly exhaust noise, and the noise is low-frequency. In the case that the noise source cannot be reduced, a comprehensive treatment of sound insulation, sound absorption, and noise reduction can be adopted for the diesel generator set.
1. Ventilation and noise reduction in the machine room.
In actual work, it is necessary to effectively reduce noise, but also to meet the airflow required by the unit.
(1) Air inlet muffler system in the computer room
①The machine room is ventilated with mechanical air intake.
②Build two air inlet ducts outside the machine room, and install a low-noise axial flow fan under the air inlet duct wall to supply air to the machine room.
③ Install a large air volume combined chip muffler in the air inlet to absorb airflow noise and mechanical noise.
④ An air inlet is opened on the outer wall of the air inlet, and special aluminum alloy shutters and protective screens are installed at the air inlet to prevent foreign objects from entering the air channel.
