210 Bar ? 300 Bar
Working pressure increased from 210 bar to
300 bar resulting in:
HPS:
Necessary pump size reduced from 355 cc to 250 cc.
Only 3 pumps needed.
Same pipe and hose dimensions.
This is because of the relation between Q’ (flow) and pressure (p) shown by the equation:
P=Q’x p, where P is the power generated by the pump, the power consumption is the same; therefore a higher pressure will result in a lower flow

Automatic mode:
The pressure set point is depending on
the engine load.
The pumps have two running modes, 1 in pressure control mode [Ctrl] (selected via the MOP screen), 2 in follow mode [Folw].
The [Ctrl] pump is running 50% and compensates immediately for deviations between actual pressure and set point. Over time the [Folw] pumps will take over the compensation while the [Ctrl] pump goes back to 50 %.
In case the pressure controlling pump faces a failure, one of the other pumps will take over pressure control.
Manual mode:
The pressure set point is set by the operator

Слайд 39Engine Driven Pumps - Summary
< >
Pump No. 1 is controlled by
ACU 1, pump 2 by ACU 2, and pump 3 by ACU 3.
Pump Nos. 4 and 5 are controlled by a binary signal, either max capacity AHEAD or ASTERN. No. 4 is controlled from ECU A, and No. 5 from ECU B.
In case of control failure of a pump, the swash plate will be forced to maximum capacity in AHEAD direction.
Pump Nos. 1, 2, and 3 have their own sensor for system pressure, connected to their controlling ACU
All pumps have sensors for suction pressure. If the pressure is to low, or all sensors are failing, a SHUT DOWN will be activated.
