Common pitfalls of using MTU diesel generators

Our company prompt the majority of users, the wrong operation will heavily affect the service life of diesel generator set, over time not only add the investment of equipment cost, but also affect the power of production, the following we together with our company to understand in the ordinary livelihood, diesel generator set error operation method what?

Error operation one: diesel engine in oil shortage

At the moment there will be conflicts due to lack of oil supply, resulting in abnormal wear or burns. To this end, the diesel generator before starting and diesel engine task process to ensure enough oil, to avoid the lack of oil caused by cylinder pulling, burning tile problems.

Error operation two: emergency shutdown with load or immediately stop after unloading load

The cooling water circulation of the diesel engine generator after flout is suspended, and the heat dissipation can drop sharply, and the heated parts lose cooling. It is easy to form overheating of the cylinder head, cylinder liner, cylinder block and other parts, attack cracks, or make the piston overblown and stuck in the cylinder liner. On the other hand, when the diesel generator is shut down without idle cooling, it will make the conflict surface lack of oil, and when the diesel engine starts again, it will be aggravated by poor smoothness and wear. Therefore, the diesel generator should be unloaded before flameout, and gradually reduce the speed, no-load task for a few minutes.

Error operation three: after cold start, load task is carried out without heating up the machine

When the diesel generator cooler is started, due to the large viscosity and poor fluidity of oil, the oil pump is short of oil supply. The conflict surface of the machine is smooth and bad due to the lack of oil, resulting in sharp wear and tear, and even the occurrence of cylinder pulling and tile burning. Therefore, the diesel engine cooling after starting should idle task heating up, until the oil temperature reaches 40℃ or more with load task; The machine should start at low speed gear, and step by step in each gear for a distance, until the oil temperature is normal, sufficient oil supply, can turn to normal progress.

Error operation four: the diesel engine after cold start bang throttle

If the throttle, the diesel generator speed sharply increased, will form some conflicts on the plane due to dry conflict and severe wear. In addition, when the throttle piston, connecting rod and crankshaft acceptance force changes greatly, causing violent impact, easy to damage parts.

Error five: in the case of lack of cooling water or cooling water, oil temperature is too high task

The lack of cooling water of diesel generator will reduce its cooling effect, and the diesel engine will overheat because of the lack of useful cooling. The temperature of cooling water and oil is too high, which will cause the diesel engine to overheat. At the moment the diesel generator cylinder head, cylinder liner, piston components and valves and other primary heat load, its mechanical properties such as strength, tolerance and other sharp decline, so that the deformation of the parts to add, reduce the cooperation between the parts of the gap, accelerate the wear of parts, severe will crack, parts stuck. Diesel generator overheating will also worsen the diesel engine incineration process, so that the fuel injector task is abnormal, bad atomization, carbon accumulation increased.

Conclusion: Normal operation of diesel generators will reduce the failure rate of generators, improve service life, reduce fuel consumption.
