What
are the preparations for the Perkins generator before starting
1. Open the supply valve
and return line (if equipped).
2. If the engine does
not start for several weeks, the fuel may escape from the fuel system and some
bubbles may be trapped in the engine fuel system when the fuel filter is
replaced. In these cases, the oil should be pumped manually to the fuel system.
3. Ensure that two air
cutoff valves 1 (shown below) are in open position.
4. If the engine does
not start for more than 3 months, the engine oil system must be pumped
manually. Follow these steps to pump the engine oil system.
A. Disconnect the speed
sensor connector on the governor control and make sure the governor stops in
the stop position.
B. Switch the key to the
starting position. Keep the key switch in this position until the oil pressure
gauge indicates 100kpa (14.5040psi). Keep the key switch in the starting
position for 10 seconds.
Note: the key switch is
part of the panel provided by OEM and the exact starting steps may vary. For
correct starting steps, refer to the instructions provided by OEM.
C. Switch the key to the
STOP position.
D. Reconnect speed
sensor connector.
Normal
starting procedure of Perkins Generator set
1. As far as possible do
not start the generator set under load conditions.
2. Transfer the key
switch to the starting (STAR) position. The engine should start immediately.
3. After the engine
starts, return the key switch to the running (RUN) position. If the engine has
not started after 10 seconds, turn the key switch back into operation and (RUN)
for 10 seconds. Then repeat steps 2 and 3. If the engine is still unable to start
after three attempts, please find out why.
4. After engine starts,
follow steps 4.a and 4.b.
A. Check the oil
pressure.
B. Check the machine for
leaks.
C. Make sure the battery
is charged.
D. After running the
engine for five minutes, check the generator monitoring system. Make sure the
engine works properly before loading.
Note: do not use
ether-like spray starting aids in cold weather. Otherwise, it could lead to
explosion and personal injury.
The use of water jacket
heaters or extra battery capacity improves the machine's startability below 10 ℃.
Methods for checking and
cleaning the core of the rear cooler of Perkins generator set
Check for damage,
corrosion, dirt, grease, insect stains, leaves, oil and other debris on the
cooler. Clean the cooler if necessary.
The rear cooler core can
not be removed and can be cleaned with proper cleaning agent. The rear cooler
must be dry before running the engine. The following are the methods for
cleaning the recooler:
Compressed air is the
first way to remove loose debris. Blow the compressed air in the opposite
direction of the fan stream. Keep the nozzle about 6mm away from the radiator.
Slowly move the nozzle in a direction parallel to the pipe. This will remove
the debris between the pipes.
High pressure water can
also be used for cleaning. Maximum water pressure for cleaning must be lower
than 275 kpa. soften sludge with high pressure water. Clean the chiller core
from both sides. Be careful not to use a high concentration of corrosive
detergent to clean the core. High concentrations of corrosive detergents can
corrode metal inside the core and cause leakage.
Reverse wash the cooler
with proper detergent.
Steam clean the cooler
to remove all residues. The radiator of a flushing cooler. Remove all other
residual debris.
Wash the cooler with hot
soapy water. Rinse the cooler thoroughly with clear water.
Use compressed air to
dry the cooler. Let the air blow in the opposite direction of normal flow.
Remove all liquid from the aftercooler. Make sure the rear cooler is dry.
Check the rear cooler to
make sure it is clean. Test the pressure of the rear cooler and replace it if
necessary.
