There are many reasons for automatic flameout, but there are mainly two aspects: one is the interruption of fuel supply; the other is obstruction of moving parts.
During normal operation, if the speed gradually slows down, the explosion sound gradually weakens, the water temperature, oil temperature and pressure are all normal, and pressing the accelerator has no effect and the engine runs gradually. turns off after a while, use a screwdriver after parking the car. If the steering wheel turns, this indicates poor or interrupted fuel supply. During operation, the oil pressure is normal, but the oil temperature is high, the water temperature is increased, and there is a paint smell. There is little or no water coming out of the cooling water outlet and steam is escaping. The machine runs hard andmakes rude noises. There is a pull of the cylinder as it approaches the stop. There is a noise and the speed gradually decreases, the steering wheel has difficulty turning back and forth and the disc does not move. steering wheel after stopping. Once the machine temperature has dropped, the steering wheel can turn again. On this basis, it can be judged that the piston is seized.
During operation, the water temperature is normal, the oil pressure drops, the oil temperature rises, there are metal shavings in the oil, the smell of If the oil is burned, the vibration of the machine increases, the sound is abnormal, the speed gradually decreases, and the machine is stopped. When the inertial rotation time is short, the handwheel does not move after parking, and the handwheel still does not move after the machine cools down, it can be judged that the spindle is burning, also known as shaft holding.
If it was enoughIf there is enough diesel in the fuel tank of the generator set, the diesel generator set may usually be equipped with a self-protection device. When the oil pressure is too low, it will do it automatically. Check the diesel engine oil level. If the engine oil level is normal, the diesel engine oil pump may be faulty or the leak may be too large in one location, preventing oil pressure from building up. If this still cannot be ruled out, you can ask.
