Diesel generator set failure will have the following precursors:
It is normal for the generator set to produce a fault, but as long as the daily maintenance of the old can maintain the long-term use of the machine, but for some major failures should be how to avoid it, this article today around these topics for you to introduce in detail:
Precursor of valve fall
The valve falling into the cylinder is generally caused by the valve rod broken, valve spring broken, valve spring seat cracking, gas lock clip off and other reasons. When cylinder head area "dangdang" tapping (touch piston valve), "there is a" friction touch valve (piston) or other abnormal sound, engine working instability, often is the precursor of valve fell cylinder, then parked immediately, otherwise it will be destroyed piston, cylinder head and cylinder liner, or even top curved rod, break the body, snap the crankshaft.
The precursor of the pound cylinder
Cylinder ramming is a destructive mechanical fault, in addition to the valve fall caused by cylinder ramming, mostly due to the rod bolts loose retreat. The connecting rod bolt is loose or stretched, the connecting rod bearing with the gap increases, then in the crankcase part can be heard "da da" knocking sound, knocking sound from small to large, finally connecting rod bolt completely off or broken, connecting rod and bearing cover thrown out, breaking the body and related parts.
precursor of broken axis
When the diesel engine crankshaft journal for hidden fatigue crack shaft shoulders, fault symptoms is unclear, with the enlargement of the crack is aggravating, engine crankcase inside a depressing tapping, speed change tapping is aggravating, engine smoke, before long, the tapping increases gradually, the engine produce jitter, crankshaft fracture, then fire. Therefore, when the engine crankcase abnormal sound, should immediately stop inspection.
precursor to a flying car
Before the "flying car", the diesel engine will generally appear to emit blue smoke, burn oil or speed instability phenomenon. The speed of the diesel engine is not controlled by the throttle at the beginning, and rises rapidly until the rated speed is exceeded, and the engine emits a lot of black or blue smoke. At this time, if we do not quickly take measures to stop the oil, gas, decompression and so on, the engine speed will continue to rise, and emit a roar, the exhaust pipe is filled with smoke, the speed is out of control, it will cause the occurrence of major accidents such as pounding cylinder.
