Preparation for periodic Operation of the Separation system
a) Before starting any work on transferring oil, Check and record the level of oil in all lubricating oil tanks.
b)
Push self-closing test cock
on the tank in use, and then close it again to release water or sediment from
it.
c)
Open the valves, as shown in
the Figures below, depending on the system and purifier selected.
NOTE: Only those need to be opened oil cleaning system valves that are associated with a specific procedure. The valve-formed oil flow path must be carefully checked to remove it from the intended tank or crankcase and pour it to the desired location.
a) Supply control air and water to the separator under preparation.
b)
Make sure the separator
brake is off and its drum is rotating freely.
c)
Make sure that the correct
gravity disc is inserted.
d)
Check that the separator
feed pump filters are clean.
e)
Switch on the separator
supply pump. The supplied oil will bypass the separator via a three-way
solenoid valve and will be directed back to the selected oil tank.
f)
Slowly open the steam supply
to the separator heater.
g)
Switch on the separator and
check for abnormal noise and vibration as it accelerates to operating speed.
h)
Start cleaning the oil with
a separator. By pressing the PROGRAM 1 soft key on its control unit. Before
applying oil to the separator drum, the control unit will perform the
procedures specified in the start program, at the same time opening the
separator drum in order to remove possible dirt.
i)
Check that the separator is
working properly and adequate performance.
j)
Make sure that neither of
the water outlets, no unusual discharges (flows) from the sludge outlet.
k)
Make sure the drain flow
control alarm is set correctly. That it does not react only the intended,
nominal discharge of water. If set incorrectly, loss of the water barrier is
possible, resulting in loss of oil entering the sludge tank.
The separator will now
operate according to the set program, discharging the sludge at predetermined
intervals.
