Troubleshooting: According to common practice, it is generally considered to be caused by air, blockage or loose seal in the diesel generator oil system. However, specifically for this diesel generator, the maintenance personnel first checked the oil system. , filter element and in other related components, no leaks or engine blocking defects were found; fuel pump, fuel injector, etc. were checked and no problems were found in addition, valve clearance, injection advance angle, etc. ; The diesel generator was also checked and adjusted, and the problem was detected. The phenomenon still exists. Finally, after careful observation and analysis by the staff, it was concluded that although the diesel generator stalled automatically, it was easy to start, and the noise and operation were basically normal. The root cause of this type of paIt always resides in the generator oil circuit system, which can be caused by insufficient fuel pre-pressure. Since there is no problem with the oil transfer pump, there is only one reason left for insufficient pre-pressure. -low pressure oil circuit pressure, which is the oil return element. There is a problem with the valve bolts. You can refer to troubleshooting daily engine failures.
Why does the diesel generator stall after starting?
There are many reasons why a diesel generator stalls after starting, such as the speed gradually decreases, operation is unstable, and white smoke is emitted from the exhaust. This phenomenon indicates that there is water in the diesel. , the cylinder seal is washed or it is automatically damaged by decompression, etc.
During automatic shutdown, operation is continuousually unstable and accompanied by abnormal knocking noises. This phenomenon is a sudden mechanical failure. Common causes include: broken crankshaft, broken piston pin, loose or broken connecting rod bolts. , the valve lock part, the valve circlip falls off, the valve spring breaks or the valve stem breaks, causing the valve to fall, etc. Once such a situation is discovered in the generator during work, it should be immediately stopped for inspection to avoid causing a major mechanical accident. It can be sent to the relevant maintenance point for complete inspection.
There are more than one or two reasons why a diesel generator stalls after starting. When a problem occurs, a solution must be found based on the specific cause.
