Principles of operation Westfalia D - Type Separators


Year: 2001
Language: english
Genre: educational
Duration: 11:04
: Mechanical Separation Division. Westfalia Separator. Mineraloil Systems GmbH
Starring: Westfalia Separator
Description: D - Type Separators
To present myself, I am the PLC Siemens C-7.1 am responsible for executing the command system of your Westfalia Separator
the UNITROL.
The UNITROL is the automation & control system of Westfalia Mineraloil separators, enabling operation in full auto- mode: it supervises all bowl operations, by controlling the water and sludge content of the bowl, and ensures excellent cleaning efficiency of your Heavy Fuel Oil.
In the demonstration that follows we will overview the entire operating sequence.....
We have more or less covered the entire separation sequence...you know, It’s fun working together with the Westfalia separators As you can see, most of the time, I do everything on my own and all my parameters are set during commissioning- but, I'm also very user-friendly in case you need to make fine-tuning adjustments...-

Start of demonstration sequence:

• bowl is spinning at full
rpm,
• feed valve is re-
circulating,
■ bowl is empty and open
now, let's close the
bowl: I'll open the
operating water valve
- this will push up
the sliding piston
... good, the bowl is now
closed
now, let’s fill the bowl
with water, so we can
flush it...
... I’ll open the
displacement water
solenoid valve...
... good, the bowl
fills up with water.
... and now, we can
perform an ejection - I
will open the operating
water solenoid valve...
... the annular piston
will slide up. and the
sliding piston will slide
down - so I can flush the
bowl
. .in order to improve visualization, the process of sliding
piston openingfclosing ("Hydrostop") has been simplified,
such that the described motion differs from the one
actually occurring in practice..
let's repeat the
sequence for a second
ejection...
let's repeat the sequence
for a second
ejection.......
• bowl is spinning at
full lpm,
• feed valve is re-
circulating.
• bowl is empty and
open
now, let's close the
bowl: I'll open the
operating water valve
- this will push up
the sliding piston
... good, the bowl is no\
closed
now, let’s fill the bowl
with water, so we can
flush it...
... I’ll open the
displacement water
solenoid valve...
... good, the bowl
fills up with water.
... and now, we can
perform an ejection - I
will open the operating
water solenoid valve...
... the annular piston
will slide up. and the
sliding piston will slide
down - so I can flush the
bowl
now, we are ready to
start separation of the
fuel oil...
... let's open the 3/2
way valve, to admit
fuel oil into the
bowl...
. the bowl tills
vith product...
at regular intervals I
must check the
water content inside
the bowl
... good, the Water
Monitoring Sensor
(WSM) is sending
me a signal...
... there is oil in the
sampling line..
so, I will re-circulate
it...
... let's open the re-
circulation solenoid
valve...
the WMS sampling
cycle is being
repeated at periodic
intervals...
... whenever the
WMS tells me there
is oil in die sampling
line, 1 always re-
circulate it...
