Determining the regulating ring by experiment
(explained using the example of oil purification)
The next smallest regulating ring is always chosen to avoid emulsification.
When the regulating ring is too wide
– the water discharging through the water outlet will contain oil.
When the regulating ring is too narrow
– emulsification will occur or
– the oil discharging through the clean oil outlet will contain water.
The water may look milky or dirty. The coloration comes from the washing of the
oil.
In the bowl a separation zone is formed between the light and heavy phases
whose centre is the separating line.
After opening the bowl, the position of the separating zone can be recognised
by the almost always visible separating line between water and oil on the under-
side of the separating disk.
variable
Fig. 63
Correctly selected regulating ring
•
The separating line between water
and oil is at the outer edge of the
disks.
Effect:
– The discharging clean oil is free of
water.
– The discharging water is free of oil.
too wide
Fig. 64
Regulating ring too wide
•
The separating line between water
and oil runs
– way outside the disks and
– too close to the outer edge of the
separating disk.
Effect:
– The discharging clean oil is free of
water.
– The discharging water contains oil
or
– oil breaks the water seal.
