Optional System Components
Optional proportional pressure control enhances the standard high and low pressure selection by
allowing the operator to select or vary the hydraulic operating pressure from the control panel or
from a remote console. From the Pressure Control Screen the high pressure can be set as a
percentage, from 0% to 100%. An electronically controlled hydraulic cartridge valve receives a
signal from the PLC and automatically makes the operator selected adjustments.
As proportional pressure controls hydraulic oil pressure, it also determines cutting water pressure
based on the intensification ratio.
7.3
Operation
The electric motor drives three pumps mounted in tandem; the main hydraulic pump, the
recirculation pump and the booster pump. The motor drives the variable displacement, pressure
compensated hydraulic pump by means of a flexible coupling.
Hydraulic fluid from the reservoir is drawn into the inlet, low pressure side of the hydraulic
pump. Oil delivered to the pump should be maintained at 110-115
°
F (43-46
°
C). Hydraulic
fluid then enters the bottom of the manifold through an internal anti-rotation check valve. After a
shutdown, the anti-rotation check valve prevents the pump from running backwards.
