Product Description:
The noise of 300KW Perkins generator set is a complex sound source composed of various sound sources.
According to the way of noise radiation, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the cause, the surface radiated noise of diesel engine can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main noise source.
1. Aerodynamic noise is caused by the unsteady process of the gas, that is, the disturbance of the gas and the interaction between the gas and the object. Aerodynamic noise radiated directly to the atmosphere, including intake noise, exhaust noise and cooling fan noise.
2. Combustion noise and mechanical noise are difficult to distinguish strictly. Usually, the noise radiated from the cylinder head, piston, connecting shaft, crankshaft and body due to the pressure fluctuation formed by combustion in the cylinder is called combustion noise. The noise generated by the impact of the piston on the cylinder liner and the mechanical impact and vibration of the moving parts is called mechanical noise. Generally, the combustion noise of the direct injection diesel engine is higher than the mechanical noise, and the mechanical noise of the non-direct injection diesel engine is higher than the combustion noise. However, the combustion noise is higher than the mechanical noise at low speed.
3. Electromagnetic noise is generated by the high-speed rotation of the generator rotor in the electromagnetic field.
