Low-noise ultra-quiet series
Low-noise ultra-quiet series
Detailed introduction:
Silent diesel generator set introduction:
The low-noise power station produced by our factory is suitable for places with high noise reduction requirements, such as densely populated urban residential areas, high-end office buildings, star-rated hotels, scientific research institutions, hospitals and colleges. Adopt scientific and perfect measures such as vibration isolation, noise reduction, sound insulation, sound absorption, etc. to greatly reduce its noise, and the noise reduction range is more than 30dBA. The power coverage of the product ranges from 10KW-1600KW. For each type of low-noise power station diesel engine, users can choose imported brand engines such as Swedish Regal, Cummins, Doosan Daewoo, etc., or pure domestic engines such as Yuchai machines, Shangchai "Dongfeng" and Tongchai "Flying Whale" , Wudong "Wandi" and other brands; the generator used, the user can choose the user can choose Wuxi Stanford, Shanghai Marathon, Shanghai Kailiang, Guangzhou Inge, Jiangxi Sanbo Motor and other joint venture brand generators can also choose domestic Landian or Other brand generators
Noise reduction facilities include:
、隔振设施,柴油机和发电机与桥架之间采用高性能减震器,以减少噪音来源。 1. Vibration isolation facilities. High-performance shock absorbers are used between diesel engines and generators and bridges to reduce noise sources.
2. Sound insulation cover, made of four to five layers of sound absorption material, sound absorption and sound insulation, the effect is obvious.
3. Inlet wind muffler, the labyrinth-type inlet muffler with three layers of sound-absorbing materials, not only ensures sufficient entry of fresh air, but also effectively seals the noise.
4. Exhaust muffler, a labyrinth exhaust muffler with three layers of sound absorbing materials, which not only ensures the unobstructed exhaust, but also effectively seals the noise transmission.
5. The use of exhaust muffler and impedance composite muffler greatly reduces the noise when exhaust gas is emitted.
6. The power cable connection adopts a fixed junction box structure, which is directly connected outside the box.
In addition, the structure of the sound insulation door is similar to that of the sound insulation cover. The window is double-glazed, and the door and window are sealed with the sound insulation grid to seal the noise to the greatest extent.
Computer room noise reduction:
With the continuous development of China's urban construction, diesel generator sets are ideal power equipment for emergency power sources, which have been widely used by post and telecommunications, airports, banks, hotels and other departments. However, the noise propagated to the surroundings of the diesel engine when it is in working condition seriously affects the residents' life and rest. As a kind of physical pollution, noise is directly felt and understood by people because of its three characteristics: regionality, randomness, and sensibility. With the development of social economy and the improvement of human environmental awareness, noise pollution has been affected by people. General attention and attention. National environmental protection departments have also formulated corresponding noise allowances according to different regions. According to the relevant regulations of the environmental protection department, combined with many years of design and construction experience, the design and careful construction of the noise reduction project of the generator room is not only ensured the normal operation of the unit, but also meets the "Environmental Noise Standard for Urban Areas" GB3095-1996) The requirements of the second type mixed zone standard are <60DB (A). Computer room noise reduction includes:
1. Noise reduction and noise reduction in the equipment room
、机房进风系统降噪消音 2. Noise reduction and noise reduction in the air intake system of the equipment room
、机房排风系统降噪消音 3 , noise reduction
、机房排气系统降噪消音 4. Noise reduction and noise reduction in the exhaust system of the equipment room
、机房门窗隔音 5. Sound insulation of doors and windows of the equipment room

Low-noise generator set features:
、噪音低,总体机构紧凑,占用空间小; 1. Low noise, compact overall structure and small space occupation;
、箱体全部为可拆卸式结构,箱体采用钢板拼接而成,表面涂有高性能防锈漆,同时具备降噪和防雨功能; 2. All the boxes are of detachable structure. The boxes are made of steel plates. The surface is coated with high-performance anti-rust paint and has noise reduction and rain protection functions.
、箱体内部采用多层屏障阻抗错配式消声结构、内置式大型阻抗式消音器。 3. The inside of the box adopts a multilayer barrier impedance mismatched muffler structure and a built-in large-scale impedance muffler.
、箱体结构设计合理,箱体内部设有大容量油箱,左右同时设有两扇检修门,以便机组故障检修; 4. The structure of the box is reasonably designed. There is a large-capacity fuel tank inside the box, and there are two maintenance doors on the left and right for the unit to troubleshoot.
、同时在箱体上开有观察窗和机组紧急停机故障按钮,以便观察机组的运行情况及在机组出现紧急情况时以最快的速度停机避免机组受到损坏。 5. At the same time, an observation window and a unit emergency shutdown fault button are opened on the box to observe the operation of the unit and stop the unit at the fastest speed to avoid damage to the unit when an emergency occurs.
