Investigating the cause of automatic flameout of 60kw diesel generator set

The 60kw diesel generator set suddenly and automatically shuts off during normal operation, mainly because the fuel supply is interrupted or the moving parts are blocked; the sudden shutdown of the generator set will greatly affect the output efficiency of the unit and affect the normal power consumption of the user. Carry out the corresponding cause investigation, eliminate the fault of the unit as soon as possible, and make the unit operate normally.

Diesel generator sets

 

       The 60kw diesel generator set suddenly and automatically turns off during normal operation, mainly because the fuel supply is interrupted or the moving parts are blocked; the sudden stop of the generator set will greatly affect the output efficiency of the unit and affect the normal power consumption of users, so it is necessary to check the automatic flameout in time. s reason. The troubleshooting method is as follows:

 

       1. During the operation, the oil pressure is normal, but the oil temperature is high, the water temperature is increased, and there is a smell of paint, the cooling water outlet has little or no water, and steam is emitted directly. There is a sound of pulling the cylinder, and the speed gradually decreases. When the car is finally stopped, the flywheel is difficult to rotate forward and reverse, and the flywheel does not move after parking. After the temperature of the machine is lowered, the flywheel can be turned again, and it can be judged that the piston is killed.

       2. During normal operation, if the speed gradually slows down, the explosion sound gradually weakens, the water temperature, oil temperature and pressure are normal, pushing the accelerator has no effect, and it gradually turns off after a period of time. After parking, use a screwdriver to turn the flywheel. Indicates that the fuel supply is poor or interrupted.

       3. During operation, the water temperature is normal, the oil pressure drops, the oil temperature rises, there are metal chips in the oil, the smell of the organic oil is dried, the machine vibration is intensified, the sound is abnormal, the speed gradually decreases, and the inertial rotation time is short when parking , After parking, the flywheel does not move, and the flywheel does not move after the machine cools down. It can be judged that the main shaft is burning tile, also known as holding the shaft.

       4. The sound of the diesel engine is dull when the engine is automatically turned off, the operation is difficult, and black smoke is emitted. This is because the diesel engine is overloaded.

 

       The above points are several common reasons for the automatic flameout of the 60kw diesel generator set introduced by Tingbo Power. Users need to check the corresponding reasons according to different situations, eliminate the fault of the unit as soon as possible, and make the unit run normally.
