The diesel generator set is mainly composed of the following four core systems, which are explained below based on the functions and reference sources of each component:
1、 Power system: diesel engine
Provide core power sources for mechanical energy, including:
combustion mechanism
Cylinder components: piston, connecting rod, crankshaft (converting linear motion into rotation)
Fuel supply: fuel tank, fuel transfer pump, filter, injector (atomized diesel and high-pressure injection)
assisted circulation
Lubrication system: oil pump, filter, oil pan (to reduce friction loss)
Cooling system: radiator, water pump, fan (maintaining operating temperature)
2、 Power generation system: AC generator
The core unit that converts mechanical energy into electrical energy:
Electromagnetic conversion components
Rotor: Rotating electromagnet (excitation or permanent magnet)
Stator: Fixed winding coil (cutting magnetic induction wire to output current)
Voltage regulating device
Automatic Voltage Regulator (AVR): dynamically controls excitation current and stabilizes output voltage
3、 Control system
The central hub for monitoring, protection, and operation:
control panel
Instrument display (voltage, frequency, oil pressure) and operation buttons
Intelligent Module
Automatic start stop and fault alarm (such as overpressure/overload protection)
4、 Auxiliary and Support System
Necessary components for ensuring safe and stable operation:
infrastructure
Public base: shock-absorbing design (rubber pad/spring) to reduce vibration impact
Protective shell: soundproof speaker (noise reduction), rain cover (outdoor protection)
Functional subsystem
Inlet and exhaust: air filter, muffler, exhaust pipe (noise reduction of 20-30 decibels)
Starting device: battery, starting motor
Extension explanation
Optional components: Mobile trailer (portable unit), container shell (large power station)
Power impact: Installing a soundproof speaker may result in a power drop of about 10%, and capacity should be reserved for selection
