Features of silent dg set
In addition to the functions of the GF series or GFZ series, low-noise dg genset also have the following features and advantages:
1. Remarkable low noise performance, the noise limit of the unit is 75dB(A) (1m away from the unit).
2. The overall design of the low-noise dg set has a compact structure, a small volume, and a novel and beautiful appearance.
3. Multi-layer shielding impedance mismatched sound insulation cover.
4. High-efficiency noise-reducing multi-channel air intake and exhaust, air intake and exhaust channels ensure sufficient power performance of the unit.
5. Large-scale impedance composite silencer.
6. Large capacity fuel tank.
7. Special quick-opening cover, convenient for maintenance.
The third generation silent dg set for home, the design is more perfect: silent dg set
1. The full range of silent dg set for home can be hoisted on the top of the box;
2. The overall structure is more compact, with built-in large horizontal muffler, lower noise; silent dg set
3. Cancel the traditional design of air intake at the bottom of the box to prevent the inhalation of debris and dust, and increase the air intake and exhaust area;
4. There is an independent output switch box on the silent box, which is convenient for cable connection (especially suitable for engineering construction and lease); silent type diesel generator set
5. The silent box has a higher level of waterproof and weather resistance. Silent dg set generator
Diesel engine generator set noise reduction program
1. Exhaust noise:
Exhaust is a high-temperature, high-speed pulsating airflow noise, which is the most energy and component part of engine noise. It is much higher than the intake noise and the mechanical noise radiated by the body, and it is the most important part of the total engine noise. Its fundamental frequency is the firing frequency of the engine. The main components of exhaust noise are the following: low-frequency pulsating noise caused by periodic exhaust smoke, air column resonance noise in the exhaust pipe, Helmholtz resonance noise of the cylinder, high-speed airflow through the valve gap and tortuous pipes When the noise, eddy current noise and the regenerated noise generated by the exhaust system under the excitation of the pressure wave in the pipeline, etc., the noise frequency increases significantly with the increase of the airflow speed.
2. Mechanical noise: Mechanical noise is mainly caused by the vibration or mutual impact caused by the periodic changes of gas pressure and motion inertia force of the moving parts of the engine during operation. The most serious ones are the following: The noise of the lever mechanism, the noise of the valve mechanism, the noise of the transmission gear, the mechanical vibration and noise caused by the unbalanced inertial force. The strong mechanical vibration of the diesel generator set can be transmitted to various places outdoors through the foundation for a long distance, and then it will generate noise through the radiation of the ground. This kind of structure noise spreads far and attenuates, and once formed, it is difficult to isolate.
3. Combustion noise: Combustion noise is structural vibration and noise generated by diesel fuel during combustion. The sound pressure level of combustion noise in the cylinder is very high. However, most parts of the engine structure have high rigidity, and their natural frequency is mostly in the middle and high frequency region. Due to the mismatch of the frequency response to the sound wave propagation, because in the low frequency range The high peak cylinder pressure level cannot be transmitted smoothly, while the cylinder pressure level in the middle and high frequency range is relatively easy to transmit.
4. Cooling fan and exhaust noise: The fan noise of the unit is composed of eddy current noise and rotating noise. The rotating noise is caused by the periodic disturbance of the cutting air flow of the fan blade; the eddy current noise is when the airflow separates on the rotating blade section The resulting vortex flow caused by the viscosity of the gas radiates an unstable flow noise. Exhaust air noise, airflow noise, fan noise, and mechanical noise are all radiated out through the exhaust duct.
5. Air intake noise: Diesel engine generator sets need to have enough fresh air supply during normal operation. On the one hand, they must ensure the normal operation of the engine. On the other hand, they must create good heat dissipation conditions for the unit, otherwise the unit cannot guarantee its performance. The air inlet system of the unit basically includes the air inlet channel and the air intake system of the engine itself. The air inlet channel of the unit must enable the fresh air to enter the genset engine room smoothly. At the same time, the mechanical noise and airflow noise of the unit can also be radiated to the dg genset room through this air inlet channel outside.
6. Generator noise: Generator noise includes electromagnetic noise caused by magnetic field pulsation between stater and rotor, and mechanical noise generated by rolling bearing rotation.
According to the above noise analysis of diesel engine generator sets. Generally, the following two treatment methods are used for the noise of dg set:
Noise reduction treatment in the oil engine room or use of soundproof units when purchasing (its noise is 80db---90db)
