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 continuously 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 duringt work, it must be stopped immediately 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.
If the user is unfamiliar with the defects and handling of the device, he or she should contact the manufacturer's after-sales service in time!
Why do gasoline generators often shut down automatically during operation?
Troubleshooting: Conventionally, this is generally considered to be caused by gas, a blockage or loose seal in the oil circuit. diesel generator system. , but specifically for the diesel generator, the maintenance personnel first checked the oil system, componentsfilter nts and other related components, and found no leaks or engine blockages, they also checked the fuel pump, fuel injectors, etc. and found no problems. In addition, the valve clearance and injection advance angle of the diesel generator were also checked and adjusted, but the defect still existed. 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 failure always lies 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 return elementof oil. There is a problem with the valve bolts. You can refer to the troubleshooting of daily engine faults.
The gasoline generator often stalls automatically during operation. There are several reasons. The first is a lack of oil, the second is a blocked oil circuit and the third. is excessive body temperature. High, four means the load is too heavy. These situations will cause the gasoline generator to automatically stall during operation.
If the machine is not very old or old, it is recommended to replace the spark plug and carburetor. If it is certain that the spark plug is not the fault, it is recommended that the oil supply line is not slick and cleaned or replaced.
Detailed information:
How to store gasoline generators when not in use usedfor a long period of time:
1. Drain all gasoline in the fuel tank and carburetor;
2. Drain all the oil in the crankcase
3. The engine oil reaches the upper limit of the oil level on the oil dipstick;
4. Close the choke and pull the starter handle to where resistance is felt;
5. unitWipe it clean and cover it with a cardboard box or plastic cover to prevent dust.
