This section provides an overview of “Scheduled Maintenance” and “Preventive
Maintenance”. In addition, maintenance of the five systems is necessary and is
described in their respective sections. Refer to the following sections for
detailed information on the operator console and systems maintenance:
• Operator Console, Section 3
• Low Pressure Water, Section 6
• High Pressure Water, Section 7
• Electrical System, Section 8
• Hydraulic System, Section 9
• Recirculation System, Section 10
The following is an overview of the primary components and their location.
• Hydraulic Pump – including electric motor, and hydraulic valve manifold
block. The pump is a variable displacement, axial piston and pressure
compensated type.
• Recirculation Pump – including a fixed displacement gear – type pump, oil
to water heat exchanger, hydraulic return line – type filter, and related
hydraulic hoses and fittings. The gear pump mounts to the back of the
variable piston pump, which has a through shaft.
• Booster Pump – includes a stainless steel vane – type pump with pressure
adjustment and high temperature switch, low pressure water filter, bypass
relief valve, and associated water tubing and fittings. The booster pump is
mounted to the back of the hydraulic gear pump, which has a through
shaft.
• Intensifier Assembly – includes one or two high pressure (HP) attenuators,
one or two hydraulic intensifier assemblies, a HP dump valve and associated
HP piping with fittings.
