DynaMAX 550P/560P/575P Waterjet Pump Operator Manual 811390 41
Proportional control valve
Electronic proportional pressure control is a closed-loop monitoring system. It adjusts pressure
when changes are sensed, such as when the operator enters a water pressure target change on
the operator interface pump or at the CNC.
A hydraulic pressure sensor gives feedback to the controller to let the system increase decrease
the pressure to the cut setpoint or the pierce setpoint. The controller gradually increases
pressure in the system. This reduces mechanical stress on the intensifier.
Gear pump
Compressing hydraulic fluid generates heat that can cause damage to equipment and decrease
the life of the fluid. The gear pump is part of the cooling loop. It moves hydraulic fluid from the
hydraulic fluid tank to the heat exchanger. The hydraulic fluid passes through a hydraulic filter
and then goes to the hydraulic fluid tank.
Hydraulic manifold and hydraulic pump
The hydraulic pump pressurizes fluid from the hydraulic fluid tank. The pressurized fluid goes
through the hydraulic manifold, which contains a shift valve that delivers hydraulic fluid to
alternating sides of the intensifier.
Hydraulic fluid from the hydraulic center section in the intensifier goes to the hydraulic fluid tank
through the hydraulic manifold.
The hydraulic manifold also houses a hydraulic transducer, which monitors hydraulic pressure in
the system. A hydraulic relief valve sends hydraulic fluid back to the hydraulic fluid tank when the
pressure is too high.
Primary motor
The primary motor drives the gear pump and the hydraulic pump.
