Into the “electric age”, the generator always occupies an important position in People’s Daily life. Regardless of the extensive application of the generator, it will also be accompanied by faults. Here is a brief analysis of the common causes of generator failure:
First, diesel generator can not start:
(1) The battery is dead;
(2) Starting motor failure;
(4) fuel stop valve failure;
(6) diesel pipeline has air;
(7) Oil pump failure.
Two, the generator no voltage output or voltage fluctuation is too large:
(1) PMG stator or rotor damage;
(2) AVR board damage;
(3) diode component damage;
(4) excitation rotor or stator damage;
(5) the stator or rotor of the main electric ball is damaged;
(6) Short circuit or open circuit of P2, P3 and P4;
(7) P6, P7, P8 wire short circuit or open circuit;
(8) X,XX wire short circuit or open circuit.
Three. Oil pressure alarm under normal oil pressure:
(1) oil pressure alarm failure;
(2) the connection of oil pressure alarm touches the ground;
(3) The DC monitoring board is faulty.
Four. High water temperature alarm when the water temperature is normal:
(1) water temperature alarm failure;
(2) the connection of water temperature alarm touches the ground;
(3) The DC monitoring board is faulty.
Five. The speed of diesel generator is stable when it is cold, and slowly rises when it is hot:
Excessive wear of electronic actuators.
