286.31 Transient Permeability Pore Pressure Intensifier Operation

Operation

Operation of the 286.31 Intensifier consists of —

• Purging and Filling the Fluid Lines

• Running a Steady State Flow Test

• Running a Transient Permeability Flow Test

Note Complete purging needs only to be done when —

• You first install the 286.31.

• You accidentally draw air into the Pressure Intensifier

Special equipment needed —

• distilled water — at least 2 gallons (8 litres)

• 1% Triton® wetting solution

• Teflon® thread sealing tape

The 286.31 is designed to operate as part of an integrated system that typically

includes —

• a Test Controller with closed-loop control electronics

• a hydraulic power supply

• a triaxial cell or pressure vessel installed in a load unit

• a confining fluid pressure intensifier

To become familiar with your system, make a trial run of the test you want to run.

Familiarize yourself with the controls and indicators used in each step, without

actually doing the step.
