How to reduce the noise of diesel generator set?

Each diesel generator set will produce a lot of noise after starting. In order to reduce the noise, many diesel generator sets purchased by schools, hospitals, hotels, guesthouses and other places have added silent boxes, so that the diesel generator set can be appropriately reduced. The noise of the generator set is higher, but the cost of the silent box is higher. The price of a 30kw diesel generator set is basically the same as that of the silent box, which invisibly increases the cost, and many companies cannot afford it. How to reduce the noise of diesel generator sets better and more economically? Huaquan Dynamics teaches you a few tricks. ⒈Reduce exhaust noise. Exhaust noise is the main noise source of the unit. It is characterized by high noise level, fast exhaust speed, and difficult management. Using a special impedance-type composite muffler can generally reduce exhaust noise by 40-60 db (a). ⒉ Reduce axial flow fan noise. When reducing the noise of the cooling fan of the generator set, two issues must be considered. One is the allowable pressure loss in the exhaust channel. The second is the required amount of noise reduction. For the above two points, resistive chip mufflers can be used. ⒊Sound insulation, sound absorption treatment and vibration isolation of the machine room (1) Sound insulation of the machine room. After the exhaust noise and cooling fan noise of the unit are reduced, the main remaining noise sources are diesel engine mechanical noise and combustion noise. The method adopted is to remove all windows except the necessary interior wall observation windows connected to the observation room, all holes and holes must be tightly sealed, and the sound insulation of the brick wall must be above 40 db (a). The computer room doors and windows adopt fireproof and soundproof doors and windows. (2) Air intake and exhaust. After the sound insulation treatment of the computer room, the ventilation and heat dissipation problem in the computer room must be solved. The air inlet should be set on the same straight line as the generator set and the air exhaust outlet. The air inlet should be equipped with a resistive piece muffler. Since the pressure loss at the air inlet is also within the allowable range, the air volume in and out of the machine room can be naturally balanced, and the ventilation and heat dissipation effect is obvious. (3) Sound absorption treatment. The five walls in the machine room except the ground can be treated with sound absorption. According to the spectral characteristics of the generator set, a perforated plate resonance sound absorption structure is adopted. (4) The exchange of indoor air and the good sound insulation of the machine room will prevent the air in the room from convection when the closed water-cooled generator is shut down, and the high temperature in the room cannot be lowered in time. Low-noise axial flow fans can be used. Coupled with a resistive chip muffler, the problem can be solved. (5) Vibration isolation of the unit. Before the generator set is installed, vibration isolation treatment should be carried out strictly in accordance with the relevant information provided by the manufacturer to avoid long-distance transmission of structural sound, and continuous radiation of air sound during the propagation, making it impossible to achieve the factory boundary noise level.
