9.1.1 Features
In addition to “slow start”, other features of the hydraulic system are listed
below:
• Hydraulic 4-way valve – directional control valve (DCV)–solenoid–operated.
Used for HP cylinder shifting.
• Closed coupled motor/hydraulic pump – pump mounts directly to the
motor, saving approximately 8-10 inches of length on the overall
pump/motor assembly, reducing footprint of the waterjet pump package.
The pump is directly coupled to the motor rather than a conventional
standalone housing and shaft coupling assembly.
• Reference hydraulic gage – used for adjusting pressures in the HI/LO relief
valves. Displays hydraulic pressure, as well as water pressure in multiple
units directly at the pressure adjustment knob.
• Built in hydraulic oil drip pan – allows for the spills to be contained within
the machine while addressing environmental issues of mixing water and oil.
• Remote dual pressure control – allows for flexibility at the cutting nozzle in
pressure adjustments for certain pure water/abrasive applications.
• Pressure adjustment control – allows for infinite pressure settings though
out the entire pressure range for flexibility.
