The genset noise three sake

DATE:2019/6/24 14:19:40 HITS:200

The noise of the generator set the the complex acoustic source is constituted by a variety of sound sources. In accordance with the noise radiation, it can be divided into the aerodynamic noise the surface radiated noise and electromagnetic noise. In accordance with the causes of the 4190 Diesel Engine noise can be divided into the combustion noise and mechanical noise. Aerodynamic noise as the main noise source. 

 

1 The aerodynamic noise is a non-stable process due to gas, that is generated by the disturbance of the gas as well as the interaction of the gas with the object. Aerodynamic noise radiation directly into the atmosphere, including the intake noise, exhaust noise and cooling fan noise. 

 

2 Combustion noise and mechanical noise of the diesel generator set is very hard to distinguish, usually formed cylinder combustion pressure fluctuations through the cylinder head, piston, Lian Hin, crankshaft, body radiate outward noise called combustion noise. The noise generated by the pistons against the mechanical shock vibration of the shock and movement of the liner member, said mechanical noise. General direct injection diesel engine combustion noise is higher than the mechanical noise, rather than direct injection diesel engine mechanical noise than combustion noise. However, the combustion noise at low speed is higher than the mechanical noise. 

 

3 Electromagnetic noise from the generator set rotor at high speed in an electromagnetic field generated by the rotation.
