Troubleshooting Difficult Starting of 600kw Yuchai Diesel Generator

When a 600kw Yuchai diesel generator is started, the crankshaft does not rotate or rotates slowly, preventing the diesel engine from entering self-operation, resulting in difficulties such as hard starting and weak starting. The specific reasons for this situation are as follows:

1.If the temperature of the diesel generator set is too low and the preheating time is insufficient, faults such as white smoke during startup and failure to ignite will occur.

2.Failure to make adequate preparations before starting leads to multiple unsuccessful startup attempts, causing excessive diesel accumulation, which further reduces the possibility of successful startup.

3.A large fuel supply advance angle has the same effect and is also one of the factors affecting starting difficulties.

4.Malfunctions occur in the controller and control unit.

The above are the reasons related to the starting difficulties of the generator set. How to detect and repair this fault? Dingbo Power Generator Manufacturer provides you with the following specific inspection methods:

1.Check if the battery is fully charged.

2.Inspect the contact between the brushes and the commutator (or collector ring). Normally, the contact surface between the bottom of the brush and the commutator should be 85%. If not, new brushes should be replaced.

3.Check if the commutator (or collector ring) is burned, scratched, dented, etc. If there is a lot of dirt on the commutator surface, clean it with diesel or gasoline. If there is severe burning, scratching, and the surface is not smooth or round, it should be properly repaired or replaced. During repair, the commutator can be turned on a machine tool and polished with fine sandpaper.

4.Check the working surfaces of the internal working contacts and the two static contacts of the electromagnetic switch. If the moving and static contacts are burned and the starter motor operates poorly, the moving and static contacts can be smoothed with fine emery cloth.
