Overview Of Typical Confining Pressure Control

Introduction

Overview Of Typical Confining Pressure Control
System

The major system components typically used with the Confining Pressure
Intensifier are shown in the following figure.

As shown in the figure, a separate hydraulic power supply acts as the primary
power source for the Confining Pressure Intensifier. Hydraulic fluid pressures up
to 21 MPa (3,000 psi) are translated into confining fluid pressures up to 140 MPa
(20,000 psi) under servo control provided by separate electronic controller
equipment.

Compressed air, driving a small fluid pump, provides the power to cause
confining fluid to flow between various system components before and after
pressurizing operations, while filling and/or emptying the triaxial cell, the
pressure intensifier, the reservoir, etc. The pump can also cause fluid to flow
between an external fluid container and either the CPI or the triaxial cell.
