Cold start dynamo Shenzhen will what fault

Generator cooler starts, because the oil of high viscosity, poor mobility, is the oil pump oil supply shortage, the machine friction surface due to lack of oil lubrication, causing a sharp wear, scuffing, even has the tile burning fault. Shenzhen generator cold start is new battery charge the state, zero degrees Fahrenheit temperatures, 30 seconds continuous discharge to 7.2V, current can continue to provide the.

Diesel engine cooling after the start should be idle until the oil heating, the temperature reached 40 degrees above to take load operation; the machine should start low gears, and circulated in every gear driving a mileage, until the temperature is normal, supply sufficient, we can turn to the normal running. If bombarded the throttle, diesel generator speed increases sharply, will cause some friction surface on the machine generated due to dry friction and severe wear. In addition, when the throttle piston, connecting rod and crankshaft accept force changes, cause severe impact, easy damaged parts. Shenzhen generator cooling water shortage will reduce the cooling effect, the diesel engine due to lack of effective cooling and overheating; high oil temperature of cooling water, oil, also can cause the diesel engine overheating. At this point the diesel generator cylinder cover, cylinder liner, piston assembly and a valve main heating load, its mechanical properties such as strength, toughness sharply, make the part deformation increases, decreases with the gap between the components, to accelerate the mechanical wear and tear, there will be a serious fault crack, parts stuck.

Generator overheating will also worsen the diesel combustion process, the fuel injector disorders, poor atomization, increased carbon. Cold start will bring a lot of harm to the Shenzhen dynamo, and if severe cases will reduce the life of generator. So, we should avoid this problem in daily use.
