LOW PRESSURE WATER

6.2 Cutting Water Supply (See Figure 6.4)
The cutting water supply includes the following:
•
Low pressure water filter (2)
•
Inlet water shutoff valve (solenoid operated) (3)
•
Booster pump (1) along with sensors and pressure controls
The low pressure water fittings are stainless steel with rubber hoses connecting
the low pressure water components. The booster pump (1) housing is also
stainless steel and is protected by the low pressure water filter (2).
The low pressure cutting water circuit allows the water to pass through the low
pressure filter (2) prior to entering the booster pump (1) to prevent debris from
damaging the pump. However, when the low pressure water filter gets loaded
up with dirt/contaminants, the water pressure exiting this filter may be too low
to supply the booster pump.
The cutting water supply circuit is automatically shut off after the motor has
been off for 2 minutes. To reset the water supply valve, press F6.
6.2.1 Normal Operating Condition
During normal operation, the low pressure water system maintains the
following conditions:
•
Filter pressure drop (gage reading 4 minus 6) not more than
1 bar (15 psi)
•
Booster pump discharge pressure gage reading 8.0-8.3 bar (115-120 psi)
NOTE
While the intensifier assembly reverses direction, the booster pressure will
fluctuate slightly above and below the normal setting. Pressure fluctuation
greater than 2 bar (30 psi) may indicate inadequate water supply to unit, or
poor booster pump performance.
