C049 - A Rock Triaxial Test Equipment

This machine is suitable for testing rock compression shear strength parameters (cohesive force, angle of internal friction), modulus ofelasticityPoisson'sratio.

Experimental process: first, cover the preparation of rock specimen with anti-oilemulsionsets and put it into triaxial cell, make the pressure rock specimen and tee centring , and then puts triaxial cell on the pressure test machine, let the pressure cell and pressure plate centring, start the machine to recognize the 0.05 mm loading rate synchronization of lateral pressure(confining pressure) and axial pressure, presetting the lateral pressure value, and keep the lateral confining pressure constant, then 0.5 MPa - 6 MPa adjust load rate and axial load until the specimen damage, record the test process of axial load and deformation values.

Main components: the axial compression loading (hydraulic) the triaxial cell (resistance to high pressure 90 mpa), pressure testing (confining pressure loading device) computer control instrument and analysis system
