Detailed Product Description: | Nanjing diesel generators | Analysis of a noise source, noise source analysis of diesel generator set diesel engine noise sound source is constituted by a variety of complex sound sources. In accordance with the noise radiation pattern, it can be divided into aerodynamic noise, surface noise and radiated electromagnetic noise. According to the causes of the surface radiation noise diesel generator set can be divided into the combustion noise and mechanical noise. Which aerodynamic noise diesel engine noise is the main noise source. 1 Aerodynamic noise is due to the process gas is unstable, that the disturbance and the gas from the gas generated by the interaction with the object diesel generator set noise. Atmospheric radiation directly to the aerodynamic noise, including the intake noise, exhaust noise and cooling fan noise. 2. Electromagnetic noise is generated by the generator rotor rotating at high speed in the electromagnetic field generated by diesel engine noise. 3. Combustion noise and mechanical noise are very hard to distinguish, usually because the combustion cylinder diesel generator set pressure fluctuations formed through the cylinder head, piston, even Xuan, crankshaft, body radiating diesel engine noise is called combustion noise. Impact on the cylinder of the piston moving parts of mechanical shock and vibration generated by diesel engine noise, said mechanical noise. General direct injection diesel engine combustion noise than mechanical noise, rather than direct injection diesel engine mechanical noise is higher than combustion noise. However, combustion noise at low speed is higher than the mechanical noise. Nanjing diesel generators | Noise Source Analysis |
