Advantages and disadvantages of small diesel generators.small diesel generator has the advantages of fuel economy, high thermal efficiency and relatively flat curve change of fuel consumption rate as well as low load.
Small diesel generator is reliable and durable.Because there is no ignition system, the fault is low.Small-scale diesel generator has a wide range of use, and its harmful emissions are relatively low.Small diesel generator has good fire safety.
The following is the wrong operation of diesel generator.
When the diesel engine runs short of oil, the oil supply on the surface of each friction pair of the generator will be insufficient.Therefore, before starting the diesel generator and during the operation of the diesel engine, sufficient oil shall be ensured to prevent the failure of the drawing cylinder and burning tile caused by the lack of oil.
Loading 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 generator cylinder head, cylinder liner, cylinder block, such as overheated parts, cracks, or make the generator jammed inside the cylinder piston.
When starting the diesel generator cold engine, due to the high viscosity and poor fluidity of the generator oil, the oil supply to the generator oil pump is insufficient. The friction surface of the generator is badly lubricated due to the lack of oil, resulting in sharp wear and tear, and even the failure of cylinder pulling and shingles burning.Diesel engine cooling after start-up, therefore, should be idle running to heat up, stay again when the oil temperature is above 40 ℃ with load operation.
