MTS Model 286-20 Confining Pressure Intensifier - Manual (Page 19)

286.20 Pressure Intensifier Operation 19
Operation
This section contains procedures for all operations involving the flow and
pressurization of confining fluid. All operating controls on the Confining
Pressure Intensifier (CPI) are described.
In addition to the Confining Pressure Intensifier, a confining pressure system
typically includes a hydraulic power supply, some type of electronic controller
equipment, and a triaxial cell. Before attempting to operate the CPI, become
familiar with each component of the confining pressure system by reading the
introduction sections of the manuals that apply.
Pressurization and depressurization of confining fluid is primarily under the
control of the electronic controller equipment. Because of the variety of
electronic controller equipment that can be used with a confining pressure
system, information provided in this manual is limited to that which will enable
you to relate CPI parameters, such as fluid pressure and fluid volumetric
displacement, to controller functions such as the command, readout and limit
functions.
A typical procedure for operating the Confining Pressure Intensifier would be:
1. Filling the reservoir; see “Filling the Reservoir From An External Source”
on page 28.
2. Filling the pressure intensifier; see “Filling the Pressure Intensifier From an
External Container” on page 30 and “Filling the Pressure Intensifier From
The Reservoir” on page 32.
3. Filling the triaxial cell; see “Filling the Triaxial Cell” on page 34.
4. Heating the triaxial cell (if applicable); see “Heating The Triaxial Cell” on
page 36.
5. Pressurizing and depressurizing the confining fluid; see “Pressurizing and
Depressurizing The Confining Fluid” on page 37.
6. Cooling the triaxial cell; see “Cooling The Triaxial Cell and Confining
Fluid” on page 41.
7. Emptying the triaxial cell to the reservoir; see “Emptying the Triaxial Cell”
on page 42.
8. Emptying the reservoir to an external container; see “Draining the Reservoir
to an External Location” on page 44.
Before operating the system for the first time, simulate the desired operation.
Locate the controls involved with each step, without actually performing the
adjustment. In this way, you will become familiar with the information that is
required or the decisions that must be made before beginning actual operation.
