Generator set rental error operation will seriously affect the service life of the diesel generator set, let’s understand in the process of daily use, diesel generator set error operation methods are what?
The diesel engine runs when the oil is insufficient. At this time, the oil supply on the surface of each friction pair will be insufficient because of the insufficient oil supply, resulting in abnormal wear or burns. Therefore, before the diesel generator and diesel engine operation process to ensure that the oil is sufficient, to prevent the lack of oil caused by the cylinder, burning tile failure.
After the cold start, the unwarmed machine will run with load. When the diesel generator cooler starts, due to the large oil viscosity and poor fluidity, the oil supply of the oil pump is insufficient, and the friction surface of the machine is poor due to the lack of oil lubrication, resulting in sharp wear, and even the failure of cylinder pulling and tile burning. Therefore, after the diesel engine cooling start should be idle running temperature, when the oil temperature reaches more than 40℃ (in winter, such as the cooling water degree reaches 60℃) when the load operation; The machine should start with low gear, and drive in each gear step by step for a period of time, until the oil temperature is normal and the oil supply is sufficient, it can turn to normal work.
With load emergency shutdown or sudden load removal immediately shut down, diesel engine generator after extinguishing the circulation of cooling water stop, generator rental cooling capacity sharply reduced, heated parts lose cooling, easy to cause cylinder head, cylinder liner, cylinder block and other parts overheating, crack, or the piston excessive expansion stuck in the cylinder liner. On the other hand, when the diesel generator is stopped without idle cooling, it will make the friction surface oil deficiency, when the diesel engine starts again, it will aggravate the wear due to poor lubrication. Therefore, the diesel generator should be unloaded before extinguishing the load, and gradually reduce the speed, no-load operation for a few minutes (no-load operation for 3 minutes).
The diesel engine burst the throttle after cold start. If the throttle, the diesel generator speed rises sharply, will cause some friction surface on the plane due to dry friction and severe wear. In addition, the piston, connecting rod and crankshaft acceptance force changes when the accelerator, causing violent impact, easy to damage the parts.
The machine overspeed or overload driving, the unit in serious overspeed, overload driving, the diesel engine will be in the load is too large, the speed is too high working conditions, easy to cause rough work, cylinder liner, piston, connecting rod and other thermal load and mechanical load increased, easy to pull cylinder and burning tile and other faults. Diesel engine such as often overloaded operation, will cause a long time in the cylinder rough combustion, easy to damage the cylinder pad.
Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators.
