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
1, Axial compression loading (hydraulic oil) device: 1500 KN 2000 KN 3000 KN (Three kinds of specifications and accuracy ±12N)
2, Triaxial cell includes a steel body and two steel end caps, when doing experiment, the two end caps which with specimen including the two Self-styledjoints, one used for connecting the lateral confining pressure and the hydraulic control system, that is adjustable, another is connected to the hydraulic control system, then test
3, sample size: 25 mm x 50 mm ¢
¢50 mm x 100 mm
¢39.1 x 80 mm size (The size is optional)
4, Lateral confining pressure maximum loading 80 MPa, controlled by the automatic servo system
5, Back pressure, (pore pressure) infiltration: maximum 16 Mpa, controlled by the automatic servo system
6, Axial compression deformation (springback) 0-12 mm ± 0.001 mm
7, Lateral deformation: 0-15 mm ±0.001 mm
8, Poisson's ratio, the axial deformation and lateral deformation ratio ±0.001 mm
9, Voltage: 380 V Power: 3 KW
10,According the automatic acquisition and analysis software analyze the rock triaxial test data real-time collection during the process to evaluate
