Error operation 1:
Diesel engine running when the oil is insufficient at this time, the oil supply will be insufficient due to the lack of oil supply on the surface of each friction pair, resulting in abnormal wear or burn. To this end, before the start of the diesel generator and during the operation of the diesel engine, it is necessary to ensure that the oil is sufficient to prevent the failure of pulling cylinder and burning tile due to the lack of oil.
Error operation two:
Emergency stop with load or sudden removal of the load immediately stop after the diesel engine generator flameout cooling system water circulation stops, the cooling capacity is sharply reduced, the heating parts lose cooling, easy to cause the cylinder head, cylinder liner, cylinder block and other parts overheating, crack, or excessive expansion of the piston trapped in the cylinder liner. On the other hand, when the diesel generator is shut down without idle cooling, the friction surface will contain insufficient oil, and the wear will be aggravated by poor lubrication when the diesel engine starts again. Therefore, the diesel generator should be unloaded before flameout, and gradually reduce the speed and run for a few minutes without load.
Error operation three:
When the diesel generator starts, due to the large viscosity and poor fluidity of the oil, the oil supply to the oil pump is insufficient, and the friction surface of the machine is poorly lubricated due to the lack of oil, resulting in sharp wear, and even the occurrence of cylinder pulling, tile burning and other failures. Therefore, the diesel engine should run at idle speed after cooling and heating up, and then run with load when the oil temperature reaches more than 40℃; The machine should start in low speed gear, and drive for a certain distance in each gear step by step, until the oil temperature is normal and the oil supply is sufficient, it can turn to normal driving.
Error operation four:
If the diesel engine is slammed after the cold start, the speed of the diesel generator set will rise sharply, which will cause some friction surfaces on the machine to be severely worn due to dry friction. In addition, the piston, connecting rod and crankshaft handling force change greatly when the throttle is fired, causing violent impact and easy to damage the machine parts.
