286.30 Pressure Intensifier Introduction 13
Introduction
This section describes the Model 286.30 Pore Pressure Intensifier, its role in the
typical rock mechanics test system, and other system components typically used
with the Pore Pressure Intensifier. Specifications and dimensions are also
included.
The Model 286.30 Pore Pressure Intensifier is designed to provide a source of
fluid at pressures suitable for use in applying pore pressure to a rock specimen in
a triaxial cell. The PPI is used to fill the specimen’s pores with pore fluid,
pressurize the fluid, and control the pressure.
Some model versions produce pore pressures up to 20,000 psi (140 MPa). The
maximum fluid volume that can flow during one stroke of the PPI’s internal
pressure intensifier can be as high as 80 cubic inches (1300 cm
3 ). See
“Specifications and Dimensions” on page 17 for specifications for all models.
