I.2.Hydraulic connections.
The connection between the various components will be made with the tubes supplied
with the unit, as shown in the diagram in Chapter I Pages 1 and 2.
•
The two suction connections between the sea cock valve (1) and the check valve
(2) will be made using the transparent
Ø
20 tube.
The remaining seawater circuit sections will be made with the blue tube
Ø
15. This is a
special tube developed to work with pressures up to 20 bar, and it is not
recommended to replace it with a different one (even with similar characteristics)
To make the connections proceed as indicated below:
•
Elbow inlet (18) Vessel pressure circuit
•
Pump outlet (4) and 5-micron filter inlet (6).
•
Pre-filter outlet (6) and the inlet elbow (E) in the high-pressure pump (8).
•
Outlet elbow (S) in the high-pressure pump (8) and the brine outlet (15).
The referred elbows marked as E and S are located in the back / lower part of the high
pressure pump (8)
Connect the elbow located in the lower part of the flow meter (12) to the to the main tank
adaptor using the blue Ø 8 polyamide tube (this adaptor is delivered with a plastic cap,
remove it before the installation).
As an optional,
a three way valve (11) can be installed in the line of produced water to
have a direct fresh water outlet. It can be very useful having a direct fresh water outlet,
without passing trough the main tank, (this valve must be one that never closes the water
flow).
As a general rule, the tube sections should be as short and as straight as possible to
avoid unnecessary pressure drops, and the connections should be completely
airtight so that air does not enter the circuit during the water absorption process.
