Common Errors About Diesel Generator Set Operation Is Described Below
Apr 11, 2017

Diesel generator error action: marine diesel oil when running

This situation will Due to shortage of oil supply caused the friction pair surface insufficient oil supply, resulting in Operation Exception Worn or burned. For this reason, diesel generator set operation before and in the course of operation of the engine must guarantee adequate oil, preventing oil loss caused by cylinders, burning failure.

Diesel generator error II: hurry down with load or remove load immediately after a sudden stop

Diesel generators remove from heat and cooling system water circulation stops, cooling capacity dramatically reduced heat loss cooled, produce parts such as cylinder heads, cylinder liner, cylinder overheating, cracking or excessive expansion of the piston stuck in the cylinder liner. The other hand, stopping without idling diesel generator cooling causes the friction surface with oil shortage, when the engine starts again will wear due to poor lubrication. Therefore, the diesel generators stall should be removed before loading, and gradually reduce speed, no-load operation for a few minutes.

Mistake three diesel generators: cold start after the warm-up load

Diesel generator during cold start, due to the engine oil viscosity, fluidity, is oil pump for oil shortage, friction surfaces of the machine due to lack of oil lubrication, causing rapid wear and even pull cylinder, burnt, and so on. Therefore, the cooling starts after idling to heat up until the oil temperature reaches 40° c above when working with load ; Machine should start hanging low gear, and take time to shift some miles for each, until the oil temperature to normal, after oil, can be converted to normal traffic.

Mistake four diesel generators: diesel cold start pounding the throttle

If pounding the gas, diesel generator rotation speed increased dramatically, killing some of the friction surface on severe wear due to friction. In addition, the detonation gas piston, connecting rod and crankshaft to accept change, causing the dramatic impact, easily damaged parts.

Mistake five diesel generators: insufficient cooling water or cooling water, oil under high temperature operation

Diesel generator cooling water volume will decrease its cooling effect, diesel engines due to lack of access to effective cooling overheating ; High oil temperature of cooling water, oil, can also cause engine overheating. Diesel generator cylinder head, cylinder, piston and valve mainly heating load capacity, its sharp decline in mechanical properties such as strength, toughness, deformation increases, reducing the clearance between the parts, accelerating mechanical wear, severe cracks, of mechanical failure. Diesel generator overheating would deteriorate in combustion process of diesel engine, injectors work disorders, poor atomization, coke increased.300KW康明斯2 拷贝.jpg
