ULTRA SILENT GENERATOR SET
What is an ultra-low-noise diesel generator set?
1.Definition and characteristics
Ultra-low noise diesel generator set is a special power generation equipment. On the basis of the traditional diesel generator set, through a series of sound insulation and noise reduction measures, the noise generated in the operation process of the unit is greatly reduced. Generally speaking, the noise level of this kind of generator set can be controlled below 70 decibels, much lower than the ordinary diesel generator set.
2. Noise reduction principle and structure design
Sound insulation cover: this is the most important noise reduction component. It is a closed shell, usually using metal sheet (such as steel plate) and sound-absorbing materials (such as rock wool, glass fiber cotton, etc.) composite made. The sheet metal can block the spread of sound, and the sound-absorbing materials can absorb and weaken the internal noise. For example, when the noise wave generated by the operation of the generator set hits the sound-absorbing material, the fiber structure inside the sound absorbing material will lose the energy of the sound, so as to achieve the effect of noise reduction.
Intake and exhaust silencing system: Install a silencer at the inlet and exhaust ports. The intake muffler can reduce the airflow noise generated when the air enters the engine, and the exhaust muffler can effectively reduce the noise of the exhaust gas discharge after combustion. The silencer has special pipes and sound absorbing materials, which eliminate noise by acoustic principles such as reflection and interference.
Shock absorber system: use shock absorber cushion or shock absorber to reduce the noise caused by vibration during the operation of the generator set. Vibrations occur when the engine and generator operate, which can make noise if transmitted to the ground or other support structures. The pads is usually made of elastic materials such as rubber, which can absorb and convert vibration energy, thus reducing noise.
3. Application scenarios
Hospital: Hospitals are a place with very strict noise requirements. Ultra-low noise diesel generator set as a backup power supply, can start power generation when the mains is interrupted, and will not interfere with the normal medical order of the hospital because of the noise, such as the rest of patients in the ward, the normal operation of precision medical equipment.
Hotel: In the hotel's power supply system, it can provide emergency power in case of power failure. As the hotel environment needs to be quiet and comfortable, the ultra-low noise diesel generator set can work without affecting the rest of the guests and the normal operation of other service facilities in the hotel.
Commercial facilities or communication base stations near residential areas: In business areas, such as supermarkets, restaurants, and communication base stations, a backup power supply is required to guarantee the operation. The low noise characteristics of the ultra-low noise diesel generator set enable it to be installed close to residential areas without causing complaints from residents due to the noise.
4. Advantages and limitations
Superiority:
Low noise, low interference to the surrounding environment, and can be used in noise-sensitive areas.
Like ordinary diesel generator sets, it can provide a stable power supply for emergency backup and main power generation.
Environmental protection is relatively good. In addition to reducing noise pollution, some ultra-low noise diesel generator sets also adopt more advanced waste gas treatment technology to reduce the impact of waste gas emissions on the environment.
Boundedness:
The cost is higher. Due to the increase of sound insulation, noise reduction and other equipment and technology, its price is usually much higher than the ordinary diesel generator set.
Volume and weight are relatively large. The noise reduction structure such as sound insulation cover will increase the overall size and weight of the generator set, which affects the convenience of its handling and installation to a certain extent.
