286.31 Transient Permeability Pore Pressure Intensifier 6
Major Components
Introduction
Major Components
1 vent is a removable cap that allows air trapped in the system to escape; also the
fill point for manually filling the reservoir.
2 cabinet houses the 286.31. It has leveling casters and a rear access door.
3 fluid reservoir holds the system’s distilled water in a clear acrylic container.
4 control panel has the valves needed to operate the 286.31. Valves are identified by name
and placed in front of a hydraulic schematic of the 286.31 and Triaxial Cell.
5 identification label lists unit specifications such as pressure, reservoir capacity, and fluid type.
6 pressure intensifier is an servovalve controlled actuator that operates a pump which boosts pore
pressure fluid up to 10,000 psi (69 MPa).
7 actuator manifold is the connection point for hydraulic components.
8 servovalve responds to system control signals to operate the pressure intensifier’s
piston.
9 reference volumes are two high pressure reservoirs used during transient permeability tests.
