Diesel generator error Operation 1: When the diesel engine runs with insufficient oil, the oil supply of each friction pair surface will be insufficient due to insufficient oil supply, resulting in abnormal wear or burn.To this end, diesel generator before starting and diesel engine running process to ensure sufficient oil, to prevent the lack of oil caused by the cylinder, burning tile fault.
Diesel generator 2: something is wrong with the load urgent stop or sudden load down immediately after unloading, diesel generator and stop cooling system of the water cycle, heat dissipation capacity sharply reduce, the heat loss of cooling, easy to cause the cylinder head, cylinder liner, cylinder block, such as overheated parts, cracks, or stuck within the cylinder piston.On the other hand, diesel generator stops without idle speed cooling, will cause insufficient oil in the friction surface, when the diesel engine starts again due to poor lubrication will exacerbate the wear.Therefore, the diesel generator should be removed before the fire, and gradually reduce the speed, no-load operation for several minutes.
Diesel generator error operation 3: After cold start, the diesel generator is run with load without heating. When the diesel generator is started, due to high viscosity and poor fluidity, the oil supply of the engine oil pump is insufficient. Due to lack of oil and poor lubrication of the friction surface of the machine, rapid wear is caused, and even faults such as cylinder pulling and tile burning occur.Therefore, after cooling and starting, the diesel engine should operate with idle speed and heat up. When the oil temperature reaches above 40℃, the diesel engine should operate with load.The machine should be equipped with low-speed gear at the beginning, and drive for a certain distance in each gear step by step until the oil temperature is normal and the oil supply is sufficient, then it can be turned into normal driving.
Diesel generator error operation four: after the diesel engine cold start bang the throttle if bang the throttle, the diesel generator speed increases sharply, will cause some of the friction surface on the machine due to dry friction and severe wear.In addition, the piston, connecting rod and crankshaft accept force changes greatly, causing violent impact, easy to damage the parts.
Diesel generator error operation 5: Running the diesel generator under the condition of insufficient cooling water or excessive cooling water and oil temperature will reduce the cooling effect, and the diesel engine will overheat due to the lack of effective cooling;High temperature of cooling water and oil will also cause overheating of the diesel engine.At this time, diesel generator cylinder head, cylinder liner, piston components and valves are mainly under high heat load, its mechanical properties such as strength, toughness and other sharp decline, so that the deformation of the parts increased, reduce the fit clearance between parts, accelerate wear parts, serious will also produce cracks, parts stuck fault.Overheating of diesel generators will also worsen the combustion process of diesel engines, making the injectors work improperly, atomizing poorly and accumulating more carbon.
