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.
