Effective Ways to Prevent Diesel Generator Set From Burning Down
by Starlight Generator dieselgeneratortechIn
this article, Starlight will guide generator customer to learn how to prevent
diesel generator set from burning down?
Keep
diesel generator set clean. During the operation of the generating unit, if dust,
water stains and other debris enter the interior, a short-circuit medium will
be formed, which will damage the insulation layer of the wire, causing a short
circuit between turns, and the temperature will rise to burn down the diesel
genset. Therefore, dust, water stains and other sundries should be prevented
from entering the generator set, and the outside of the diesel generator set
should be cleaned frequently to ensure good heat dissipation of the genset.
Observe
the diesel generator set for vibration, noise and abnormal odor. In the
operation of diesel generator sets, especially high-power gen sets, it is
necessary to check whether the anchor bolts, the end cover of the generating
set, and bearing glands are loose, and whether the grounding device is
reliable. If it is found that the vibration of the diesel generator set is
intensified, the noise is increased and the odor is generated, it is necessary
to stop as soon as possible to find out the cause and eliminate the fault.
Keep
the working current of the diesel genset in a stable state. Due to excessive
load, low voltage or mechanical jam of the generator set will cause overload
operation of the diesel power generating set. Therefore, in the operation of
the generator, it is necessary to pay attention to checking whether the
transmission is flexible and reliable, whether the concentricity of the
coupling is standard, the flexibility of the gear transmission, etc. If any
stuck phenomenon is found, it is necessary to stop the machine immediately and
eliminate the fault before running.
Regularly
inspect and repair the control equipment of the diesel generator set to ensure
its normal operation. The technical status of the diesel generating unit
control equipment plays a decisive role in the normal start of the generator
set. Therefore, the control equipment of the power generating set should be
located in a dry, ventilated and easy to operate position, and regularly dust.
Frequently check whether the contactor contacts, coil core, wiring screws, etc.
are reliable, and the mechanical parts are flexible, so as to maintain a good
technical state, thus ensuring that the diesel genset works smoothly without
being burned.
Always
check whether the temperature and temperature rise of the power generator set
are too high in operation. It is necessary to check whether the bearing of the
diesel generator set is overheating and lack of oil. If the temperature rise
near the bearing is found to be too high, it should be stopped immediately for
inspection. Whether there is crack, scratch or damage on the rolling body and
the raceway surface of the bearing, whether the bearing clearance is
excessively shaken, and whether the inner ring rotates on the shaft and so on.
If the above phenomenon occurs, the bearing must be renewed.
Check
whether the three-phase current of the diesel generator set is balanced. For
three-phase asynchronous diesel generator sets, the difference between the average
value of any one-phase current and the other two-phase current shall not exceed
10%, so as to ensure the safe operation of the generator set. If it exceeds, it
indicates that the genset is faulty. It should find out the cause and eliminate
the fault before running.
Note
that the above operation can not only improve the performance of the generating
set, but also extend the life of the unit. Starlight is a professional
manufacturer of diesel generator sets, which can produce various types of generator
sets according to customer needs. Brands include Cummins, Perkins, Volvo,
Deutz, Ricardo, Shangchai, Weichai and Yuchai.
