High-pressure water system
The plungers in the intensifier compress water up to 4,137 bar or 413,685 kPa (60,000 psi). This pressurized water exits
the high-pressure end through a check valve and goes to the attenuator.
Attenuator
The stroking of the piston generates a brief change of water pressure in the high-pressure ends, causing the water
pressure to drop. The attenuator reduces pressure fluctuations caused by reversal of the intensifier.
High-pressure ends
Ceramic plungers connected to each side of the piston extend into the left and right high-pressure cylinders. Hydraulic
fluid pushes the piston to 1 side while inlet cutting water fills the empty cylinder. The plunger on the opposite side of the
cylinder compresses high-pressure water for cutting or piercing.
Bleed-down valve
The bleed-down valve is a normally open, air-actuated dump valve. When the pump is turned off or it is changed from cut
(high) pressure to pierce (low) pressure, the valve opens to discharge high-pressure water from the system.
