Low Noise Diesel Generator Set

Kecheng is one of the famous China Low Noise Diesel Generator Set manufacturers and suppliers.

Silent diesel generator sets, in addition to possessing all the functions of series diesel generator sets, also feature the following characteristics: low noise levels, compact overall structure, and minimal space occupation; the entire enclosure is made of removable components, constructed from steel plates with high-performance anti-rust paint applied on the surface, providing both noise reduction and rain protection; the internal structure employs multi-layer barrier impedance mismatching silencing technology and an integrated large-scale impedance silencer. The design of the enclosure is rational, featuring a large capacity oil tank inside and two inspection doors on either side for maintenance when the unit malfunctions; observation windows and emergency shutdown buttons are also provided on the enclosure to monitor the units operation and quickly shut it down in case of emergencies to prevent damage

Characteristic

	Well equipped Two-stage heavy-duty filtration system to protect the engine and extend the operation and maintenance interval of the unit Heavy load multi-energy LCD control system, to meet a variety of application requirements
	Convenient transportation Compact structure, multiple modes of movement, can save transportation costs for users The lifting point is located at the center of gravity of the whole machine to ensure safe and efficient transportation
	wide application Optional mobile trailer chassis to meet different mobile requirements Excellent noise level, especially suitable for noise sensitive environments The box is made of double-sided galvanized steel plate and dry powder spraying process, which has excellent noise reduction and heat dissipation effect, rust prevention and corrosion resistance, and is suitable for various harsh environment applications.

Aircraft noise reduction facilities

1. Vibration damping facilities: high performance shock absorbers are used between diesel engine and generator and bridge frame to reduce noise generated by vibration.
2. Sound insulation hood, using four to five layers of sound absorbing materials, the technology is mature, sound absorbing and sound insulation, the effect is obvious.
3. Air intake silencer, a labyrinth air intake silencer with three layers of sound absorbing materials, which not only ensures the sufficient entry of fresh air, but also effectively seals the noise outward.
4. Exhaust silencer, a labyrinth exhaust silencer with three layers of sound absorbing materials, which not only ensures the smooth exhaust, but also effectively seals the noise propagation and diffusion.
5. Exhaust muffler, the use of impedance composite muffler, greatly reduces the noise when exhaust emissions, emissions can meet the national standards.
6. The power cable connection adopts the 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 hood. The window adopts double glazing, and the doors and Windows are strictly sealed with the sound insulation hood to maximize the sealing of noise.
