Noise reduction structure and application of silent generator set

靜音發(fā)電機組降噪結(jié)構(gòu)設(shè)施：

Noise reduction structure and facilities of silent generator set:

1、減振設(shè)施，柴油機和發(fā)電機與橋架之間采用高性能減震器，減少震動產(chǎn)生的噪音。

1. Vibration damping facilities. High performance shock absorbers are used between the diesel engine and generator and the bridge to reduce the noise generated by vibration.

2、隔聲罩，采用四至五層的吸音材料的隔聲罩，技術(shù)成熟，吸音隔音，效果明顯。

2. The sound insulation cover is made of four to five layers of sound-absorbing materials. The technology is mature, sound-absorbing and sound-insulating, and the effect is obvious.

3、進風消聲體，三層吸音材料的迷宮式進風消聲體，既保證新鮮空氣的足夠進入，又有效地密閉了噪聲外揚。

3. The air inlet silencer is a labyrinth air inlet silencer with three layers of sound-absorbing materials, which not only ensures the sufficient entry of fresh air, but also effectively seals the external noise.

4、排風消聲體，三層吸音材料的迷宮式排風消聲體，既保證排風的通暢，又有效地密閉了噪聲傳播擴散。

4. Exhaust muffler, a labyrinth exhaust muffler with three layers of sound-absorbing materials, not only ensures the smooth exhaust, but also effectively seals the noise propagation and diffusion.

5、排氣消聲器，阻抗復合型消聲器的采用，大大降低了廢氣排放出時的噪音，排放能夠符合國家標準。

5. The adoption of exhaust muffler and impedance composite muffler greatly reduces the noise of exhaust gas emission, and the emission can meet the national standards.

6、電力電纜連接采用固定式接線盒結(jié)構(gòu)，直接在箱體外連接。

6. The power cable connection adopts the fixed junction box structure, which is directly connected outside the box.

另外，隔聲置門的結(jié)構(gòu)與隔聲置類似，窗采用雙層玻璃，門窗與隔聲置嚴格密封，大限度地密封了噪聲。

In addition, the structure of the sound insulation door is similar to that of the sound insulation device. The window adopts double-layer glass, and the door and window are strictly sealed with the sound insulation device, which seals the noise to a great extent.

靜音發(fā)電機組的應用：

Application of silent generator set:

柴油發(fā)電機組/低噪音柴油發(fā)電機組符合 GB2820-90等相關(guān)國家標準，廣泛應用干郵電，通訊，賓館、娛樂、醫(yī)院、學校、高層等建筑以及工礦企業(yè)等對噪聲有嚴格要求的供電場所。

Diesel generator sets / low-noise diesel generator sets comply with gb2820-90 and other relevant national standards, and are widely used in dry post and telecommunications, communications, hotels, entertainment, hospitals, schools, high-rise buildings, industrial and mining enterprises and other power supply places that have strict requirements on noise.
