BPC-series-Balanced passive triaxial cell
Description
The BPC-series balanced passive triaxial cells are employed for triaxial mechanical testing on rock specimens subjected to uniform confining pressures and compressive axial forces. An external load frame must be used to apply axial loads. The cell hosts an axial load ram that self-compensates the up thrust exerted by the cell pressure. Moreover, this great feature prevents the cell pressure load from being expended on the load frame, thereby reducing the load frame capacity amount required to achieve the same deviatoric stress. Disturbances to constant confining pressure during axial loading are also eliminated. The sample is fitted into a Teflon sleeve between hardened steel endcaps and the assembly is immersed in confining pressurized oil. Electrical feed-through connectors, integrated into the cell base, permit the installation of in-vessel instrumentation, e.g. axial and radial deformation measurement devices, ultrasonic platens, and other special transducers to be used. Top & bottom pore fluid ports for pore pressure tests at both upper and lower platens are an integral part of the cell architecture. A low friction loading piston is provided with the triaxial cell. Different diameter platens, pistons and additional feed through connectors can be supplied to perform custom sample geometry tests. If required, the cell can also be provided with a heating mantle.
