Common Faults Of Self-Starting System Of Diesel Generators
At present, diesel generators have become more and more widely used, because the energy saving and environmental protection efficiency that diesel generators bring us is more efficient and environmental friendly. A self-starting system is an important part of the diesel generator set, so when it fails to work, it will directly affect the normal operation of the generator set. Today, lets take a look at the common faults of the self-starting system of diesel generators.
1. Failed to start. When the self-starting system of the diesel generator set fails to start, it is generally caused by the failure of the starter motor, or it is caused by the lack of lubricating oil in the starter motor and the system cannot be started normally; in general, the starting force of diesel generators will be weakened by some steam engine, or the second-level The circuit is damaged or there is too much current output, which will also cause the starting system to fail to work.
2. Starting too hard. When the diesel generator sets self-starting system begins to start too hard, it is mainly caused by the change of the power supply voltage or the rust of the starter motor parts. The more serious the rust, the harder the starting force will be. In addition, the fault of the starter driving device can also cause it.
3. The starter cannot bear. When the self-starting system of the diesel generator set cannot bear too much torque, it is usually caused by the fact that the starter motor has been used for a long time, and its parts have been worn away, which reduces its power. In addition, the starter cannot bear too much torque due to problems with the flywheel.
4. The crank angle cannot be controlled. When the self-starting system of the diesel generator set cannot be controlled by the crank angle, it is almost caused by the fault of the control device, or there is inconsistent displacement of the self-starting system, resulting in inaccurate sensing of the crank position, and its judgement result is incorrect.
5. Poor performance. The poor performance of the starter motor is mainly caused by the problems of the starter motor itself. Generally, the quality of the contactor of the starter motor will affect its performance, and the service life of the starter motor will be significantly reduced if it is fail-proof.
The above are the common faults of the self-starting system of diesel generators. The problems of diesel generators should be checked in time, and the maintenance must be done in time when some failures are found, so that the generator sets can be used normally and stably.
