9.3.3 - Service liquid: Total recovery system
This system has total recycle of the service liquid
without fresh liquid make-up from an outside
source.
A heat exchanger is required to lower and control
the temperature of the recycled service liquid: for
sizing and calculations of heat loads consult
Pompetravaini.
A circulating pump will be required for those
applications where the vacuum pump operates for
extended period of times in the pressure ranges
above 400/600 mbar or when there are high
pressure drops in the closed loop including the
heat exchanger (over approximately 1.5 m).
The liquid level in the separator tank should not be
above the pump shaft centreline.
Losses of liquid from the closed loop must be
compensated with an equal amount from an
outside source.
Schematic fig. 20 illustrates the system with total
recovery of the service liquid.
