How to shoot the common Hamac diesel generator error
Date: May 05, 2015 Source: Hamac Machinery
Hamac Power remind the majority of users, wrong operation would adversely affect the service life of diesel generator set, long run not only increase the cost of investment in equipment, and also affects the efficiency of the production, people look and spark one up in everyday life, the diesel power What unit error operation?
Wrong operation: diesel engine operation in the oil shortage
At this time due to lack of oil supply caused by insufficient oil supply of each friction surface, resulting in abnormal wear and tear or burn. For this reason, before the start of the diesel generator and the process of the operation of the diesel engine to ensure sufficient oil to prevent Scuffing, bush-burning failure due to lack of oil.
Wrong operation: emergency stop or suddenly removable load with load immediately after shutdown
Cooling water circulation stops flameout diesel generator, cooling capacity is sharply reduced loss of cooling heating parts, could easily lead to the cylinder head, cylinder liner, cylinder block and other parts to overheat, resulting in cracks or excessive expansion of the piston stuck in the cylinder liner within. On the other hand, the diesel generator is shut down without idling cooling, make the friction surface oil, increased wear due to poor lubrication when the diesel engine is started again. Therefore, diesel generator flameout should drop the load, and gradually reduce speed, no-load operation a few minutes.
Error operation: not warm up after a cold start with load
Cold start of diesel generator, oil viscosity, poor liquidity, inadequate oil pump oil, the machine friction surface due to lack of oil poor lubrication, resulting in rapid wear and tear, or even pull cylinder, bush-burning and other faults. Therefore, after the start of the diesel engine cooling should idle temperature, the standby oil temperature reaches above 40 ℃ with load; machines started hanging low gear and orderly travel for a distance in each gear oil until the oil temperature is normal, full only after converted to normal driving.
Error Operation: Meng throttle diesel cold start
If Meng throttle, the diesel generator speed sharp rise will cause some friction surface on the machine produce dry friction and severe wear. In addition, H-throttle piston, connecting rod and crankshaft the admissibility force changes, caused by a violent shock, fragile parts.
Error operation: In the case of insufficient cooling water or cooling water, oil temperature operation
Diesel generator cooling water shortage will reduce the cooling effect, the diesel engine is overheating due to the lack of effective cooling; cooling water, high oil temperature of oil will cause engine overheating. Diesel generator cylinder cover, cylinder liners, piston assembly and valve heat load, the mechanical properties such as strength, toughness, sharp decline in parts deformation increases, decreases with the gap between the parts, to accelerate the mechanical wear, also produce severe cracks, mechanical failure jammed. Deterioration of diesel engine combustion process, diesel generator overheating also so injector disorders, poor atomization, coke increased.
