Hydromatic Stinger
Technical Description
General description of the Hydromatic installation
Water supply
Water is delivered from a ROSENBAUER Centrifugal Pump.
The DRE electronics ensures that the pump pressure is regulated
to a value adjusted before, the so called "Nominal Value". This is
independent of the discharged amount.
The DRE electronics engages the priming pump if necessary.
Foam compound supply
Foam compound is delivered by a gear pump, driven by a separate
hydraulic motor. The foam compound is pumped to every single
pressure outlet via a separate piping system.
The electronic for the hydraulic oil pump ensures that the foam
compound pump pressure is regulated to a value, 0.5 bar higher
than that preadjusted at the water side. This is also independent of
the discharged amount. Only foam compound actually consumed,
is sucked out of the foam compound tank or the external foam
compound container.
Water/Foam proportioning
Foam compound is proportioned at every pressure outlet by a
separate ACR Pressure Proportioner.
At every single pressure outlet it is possible to deliver water or
water/foam-mixture with adjustable proportioning rates.
ATTENTION !
To avoid critical operational circumstances and to react immediately
the operator must in easy reach of the pump control panel.
