Section 7. HIGH PRESSURE WATER SYSTEM – SL-IV 15hp
7 High Pressure (HP) Water
The high pressure (HP) water system takes the relatively low pressure
water inlet to up to 3,800 bar (55,000 psi) supplying orifice diameters
appropriate to the waterjet pump’s operating power (See Specifications,
Section 11).
7.1 Components
The high-pressure water components include the hydraulic intensifier,
HP attenuator, HP dump valve and HP piping. Maintenance on the
intensifier is discussed in detail in this section. In addition to HP
components and assemblies, the hydraulic cylinder aspects of the
intensifier are discussed in this section.
