Analysis of noise source of 250KW Perkins generator set

The noise of 250KW Perkins generator set is a complex sound source composed of multiple sound sources. According to the mode of noise radiation, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the causes, the surface radiated noise of diesel engine can be divided into combustion noise and mechanical noise. Aerodynamic noise is the main noise source.


1. Aerodynamic noise is caused by the unstable process of gas, that is, the disturbance of gas and the interaction between gas and object. Aerodynamic noise radiated directly into the atmosphere includes intake noise, exhaust noise and cooling fan noise.

2. It is difficult to strictly distinguish between combustion noise and mechanical noise. Generally, the noise radiated from the cylinder head, piston, Lianxuan, crankshaft and engine body by the pressure fluctuation caused by combustion in the cylinder is called combustion noise. The noise generated by the impact of piston on cylinder liner and mechanical impact vibration of moving parts is called mechanical noise. Generally, the combustion noise of the direct injection diesel engine is higher than the mechanical noise, while 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 generator rotor rotating at high speed in the electromagnetic field.


200KW Perkins diesel generator meets the standard


The purchase of Perkins diesel generator for communication must meet the requirements of Grade G3 or G4 in GB2820-1997, and meet the requirements of the 24 performance indicators specified in the Implementation Rules for the Quality Certification and Testing of Communication Diesel Generator Sets, and must pass the strict inspection of the Quality Supervision and Inspection Center for Communication Power Supply Equipment set up by China's industry competent department.


The purchase of the Perkins diesel generator for military communications must meet the requirements of the relevant GB2820-1997, GJB standards and the Quality Inspection Standard for Communication Power Supply Equipment formulated by the relevant military departments, and must pass the strict inspection of the equipment quality by the relevant organization departments.


Main factors to be considered when purchasing 100KW Perkins diesel generator set


The main factors to be considered when purchasing 100KW Perkins diesel generator set are mechanical and electrical performance, unit purpose, load capacity and range of change, automation function, etc.


1. Purpose. Because the Perkins generator set can be used in three situations: common, standby and emergency. Therefore, the requirements of 100KW Perkins diesel generator set for different purposes are different;

2. Load capacity. The load capacity and load variation range shall be selected according to different purposes, and the single machine capacity and standby capacity shall be determined;

3. Operating environmental conditions (mainly refer to altitude and climatic conditions);

4. Selection of 100KW Perkins diesel generator set;

5. Pay attention to the generator and excitation mode when purchasing 100KW Perkins diesel generator set;

6. Selection of automation function of 100KW Perkins diesel generator set.
