286.31 Transient Permeability Pore Pressure Intensifier 14 Operation
The following warning, caution, and note apply during all steps.
You will be working with very high pressures — The spray from a leak could
cut your skin.
The 286.31 develops intensely high pressures (10000 psi/69 MPa). Broken lines
or fittings could produce a skin cutting spray.
Stop if you can’t build up to test pressure. You may have a leak somewhere.
Reduce pressure to zero, then find and repair the leak.
Fluid hotter than 165°F/75°C can damage the acrylic fluid reservoir and its
hoses.
Watch the temperature of the confining fluid in your triaxial cell —
especially if your cell has heaters. The confining fluid will heat the pore
fluid.
Wait for the confining fluid temperature to cool below 165°F/75°C before
drawing the pore fluid back into the 286.31 reservoir.
Use only distilled water in the 286.31—
Use any other fluid and you can wreck its seals.
Note Adding a 1% Triton wetting solution to the distilled water will lubricate the
286.31’s seals and make them last longer.
