The Beidou Power diesel generator set manufacturer introduces the causes of unstable frequency conversion in ultra-quiet diesel generator sets:
Air enters the fuel line of the diesel generator set’s fuel supply system, causing unstable speed of the diesel engine.
2. There is a blockage in the oil circuit.
3. Uneven oil supply from each branch pump of the high-pressure oil pump causes the diesel engine’s speed to fluctuate.
4. Poor atomization of the fuel injected by the fuel injector in the cylinder results in different explosive forces when diesel burns in the combustion chamber.
5. The stable adjustment component inside the AVR control board is damaged.
6. There are poor contact or short circuit faults in the contact parts of each circuit of the diesel generator set.
