Diesel Generator Set Maintenance
by Starlight Generator dieselgeneratortechBelow are
some tips for users to maintain their diesel generator.
1. When the generator is in
operation, all screens should be locked and the key shall be kept by hand. It
is especially important not to leave the key in the lock.
2. Note that insulation tools
should be used to ensure circuit safety when connecting or disconnecting the
circuit.
3. Check engine starting motor
batteries and wiring for metal objects. Clean up immediately.
4. Once the generator has a major
fault, can press the control screen emergency stop button emergency shutdown.
(this method is not advocated because frequent adoption can cause damage to the
equipment.)
5. Before the generator stops,
pay attention to load separation, let the unit idling for a period of time
until the complete shutdown. In addition, the forced shutdown of the generator
can easily cause damage to the unit by installing part of the unit with the
stop valve, or by turning off the key switch of the control screen.
6. Generator monthly maintenance content:
A. Clean up the dust on the
surface of the unit, etc.
B. Check whether the speed
control rod is flexible and lubricate the connection points;
C. Change cooling water, measure
PH value before and after replacement (normal value is 7.5-9), and do a good
record of measurement, if necessary, add drug treatment;
D. Check the tension of fan and
charger belts and adjust them if necessary
E. If the generator is used in
important occasions, the no-load test should be started for at least 10 minutes
per week, and the half-hour test with load should be done every six months.
Besides daily maintenance, how to keep diesel
generator safe in winter or cold weather is also important.
1. Selection
of diesel oil Carefully
Light diesel oil with low
freezing point and good ignition performance should be selected in winter, and
the freezing point of diesel oil should be lower than the local minimum
temperature of 7-10 ℃ in the current season. Because
the low temperature in winter will reduce the flow of diesel oil, increase the
viscosity that will lead to uneasy spray. As a result, it is easy to cause poor
atomization due to the diesel can not be fully burned, resulting in the power
of diesel generators decreased and waste.
2. Do not
release water too early or release water without cooling water
Before flame out should idle
operation, waiting for cooling water temperature to 60 ℃, water is not hot and then rest assured. If
the cooling water is released prematurely, the body will suddenly shrink and
crack when the temperature is high. The residual water should be discharged
thoroughly when discharging water to avoid the expansion of the body.
3. It is not
suitable to start with open fire
Do not remove the air filter,
with cotton yarn dipping with diesel fuel ignited to make a fuse placed in the
intake pipe to implement combustion booster. In the starting process, the
dust-containing air of the outside world will inhale directly into the cylinder
without filtration, forming abnormal wear of the piston, cylinder and other
parts, and will also form the rough operation of diesel engine and harm the
machine.
4. The engine should run at low
speed for 3-5 minutes after starting in order to raise the temperature of the
diesel engine, check the working condition of lubricating oil, check the normal
operation before it can be put into normal operation. In the operation of the
diesel engine, the service life of the valve assembly will be affected by
reducing the sudden acceleration of the speed or stepping on the throttle to
the maximum operation, otherwise the long time will affect the service life of
the valve assembly.
5. Attention
should be paid to body insulation
Winter temperature is low, easy
to make diesel engine operation cooling excessive. Therefore, heat preservation
is the necessary measure to prolong the life of diesel generator in winter. In
the northern region, diesel generators should be equipped with insulation cover
and thermal insulation curtain and other cold-proof equipment in winter.
6. It is not
advisable to bake oil bottom with open fire
Avoid causing oil in the oil pan
to degenerate, even scorch, smooth function decline or thorough loss, and then
aggravate machine wear. Low freezing point oil should be used in winter, and
the engine oil temperature can be raised by using water bath outside the
machine to warm up the engine oil.
