Installation of hydraulic station
7.2
Identification of components
1. The main components of the hydraulic station are:
–
Two isolating valves (Fig. 10, Item 1 & 2) with integral
thermometers which display the solar primary flow
and return temperatures.
–
A safety group (Fig. 10, Item 3, supplied unconnected),
which protects the solar primary circuit. The pressure
relief valve and pressure gauge are integrated in the
safety group.
–
A non-return valve in both feed and return prevents
the possibility of gravity circulation in the solar
primary circuit.
–
A solar circulation pump (Fig. 10, Item 4).
–
A flow meter with fill & drain valve and shut-off valve
(Fig. 10, Item 5).
– An
air
separator.
2. The heat transfer fluid is circulated by the solar circulation
pump integrated in the hydraulic pump station (Fig. 10).
3. The hydraulic station has a solar differential temperature
controller (Fig. 10 Item 6) integrated into the front
insulation moulding. This is pre-wired to the solar pump.
