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.
