What is the wrong way to operate a diesel generator?
Operation Error 1: The diesel engine operates in a shortage of oil. Due to the shortage of oil, the fuel supply on each friction surface is insufficient, which may lead to abnormal wear and burns. Therefore, it is necessary to ensure sufficient flow before starting the diesel generator and during the operation of the diesel engine to prevent cylinder oil extraction caused by insufficient oil and prevent failure combustion. (David assell, Northern Exposure, diesel) Fault 2: emergency stop of load, or suddenly lift the load, diesel generator stop, cooling system water circulation stops, cooling capacity drops sharply, heating parts lose cooling, cylinder head, cylinder liner, cylinder cylinder block and other parts overheating, Crack fault Operation 3: after cold start, no preheating and the diesel generator running with load cold start, oil viscosity, fluidity, oil supply shortage, mechanical friction surface oil insufficient lubrication, resulting in severe wear, cylinder, combustion and other failures. Therefore, after the cooling of the diesel engine begins, the temperature rises during idle operation, and the temperature of the atmospheric oil reaches more than 40. Please start the load. Low speed gear must be applied when the machine starts, the oil temperature is normal, and the driving distance of each file is driven in turn, in order to run normally until sufficient oil is provided. Operation 4: After the cold start of the diesel engine, hit the accelerator, the speed of the diesel engine rises sharply, and the friction surface of the machine is seriously worn due to dry friction. In addition, when knocking the accelerator, the piston, connecting rod, crankshaft receiving force has changed greatly, suffered serious impact, parts easy to damage. Fault operation 5: insufficient cooling water, or cooling water, oil temperature is too high, insufficient starting diesel generator cooling water, cooling effect will decrease, diesel engine can not be effectively cooled, overheating cooling water, oil oil temperature is too high, diesel engine will overheat. At this time, diesel generator cylinder cover, cylinder liner, piston assembly and valve and other main thermal load is large, mechanical properties (such as strength, toughness, etc.) decline sharply, parts deformation increases, the spacing between parts decreases, parts wear acceleration. In severe cases, overheating of diesel generators can exacerbate the diesel engine combustion process, resulting in poor fuel injector operation, poor fog, and increased coal piles.
