The low noise diesel generator set produced by our factory has introduced a new series of products developed by absorbing the advanced technology of foreign low noise generator sets. The products meet the national standards of GB/T2820-1997 or GB12786-91, and have passed the CE certification of foreign countries, and are deeply loved by customers at home and abroad. Low noise diesel generator set is widely used in post and telecommunications, Hotel buildings, entertainment places, hospitals, shopping malls, industrial and mining enterprises and other places which require strict environmental noise, as a common or standby power supply.   Characteristic: 1. Significant low noise performance. The unit noise limit is 75dB (A) (1m from the unit). 2. The low noise diesel generator set is compact in design, small in size and beautiful in shape. 3. Multilayer shielded impedance mismatched enclosure. 4, efficient noise reduction type multi-channel intake and exhaust, intake and exhaust channels, to ensure adequate dynamic performance of the unit. 5, large impedance composite muffler. 6. Large capacity fuel tank. 7, the ad hoc quick opening cover plate is convenient for maintenance.   Noise reduction facilities include: 1. Vibration isolation facilities. High performance shock absorbers are used between diesel engines and generators and axles to reduce noise sources. 2, sound insulation cover, using four to five layers of sound absorbing material made of noise insulation cover, sound absorption and sound insulation, the effect is obvious. 3. The intake anechoic body and the labyrinth intake anechoic body with three layers of sound absorbing materials not only ensure the fresh air to enter sufficiently, but also effectively seal off the noise. 4. The exhaust anechoic body and the labyrinth exhaust anechoic body with three layers of sound absorbing materials not only ensure the smooth exhaust, but also effectively seal the noise transmission. 5. The use of exhaust muffler and impedance compound muffler greatly reduces the noise when exhaust gas is discharged. 6, the power cable connection adopts a fixed junction box structure, which is directly connected outside the box.
