Electronic Power and Triaxial testing machine Usage Automatic Triaxial Apparatus

application:

It is a method of the determination of shear strength of kinds of soils. Usually with 3-4 cylindrical specimens, under different ambient pressure (i.e., a small primary stress sigma 3), axial pressure is inflicted respectively. Shear strength parameters are obtained according to Mohr coulomb theory.

Function: Unconfined test , UU, CU, CD bearing ratio test, etc

Consolidated undrained (UU) test is drainage is not allowed in test in in the process of inflicting surrounding pressure and enhance pressure until the destruction. It is suitable for determination of fine particle soil and sand soil

Consolidated undrained (UU) test make sample drainage and consolidation under ambient pressure. under the undrained condition, Increase the axial force until destruction. It is suitable for shear strength of Clay soil and pressure coefficient of sand soil and pore.

Consolidated drained triaxial test CD Test make sample drainage and consolidation under ambient pressure. Increase the axial force until destruction under the condition of allowing sample drainage. It is suitable for shear strength of Clay soil.( A sample multilevel confining pressure and axial pressure to shear, it is suitable for three axis undisturbed soil, disturbed soil and irregular fracture crack soil that can not obtain multiple specimen)

Strain triaxial important component: Controller, software, sensor, confining pressure, back pressure, pore pressure system and the host in the attachment

Windows software collection and processing software, supporting network, compatible with the existing computer system, easy to use, free upgrades, machine does not need an additional data acquisition system, full computer control, matching

Liquid crystal display, keyboard input, axial stress and axial deformation, confining pressure, back pressure, pore pressure, volume change, speed and real-time clock calendar display, etc

Three axis host adopts the method of in block cast. It is with strong and stable structure, small volume, the output is big, low noise. Advanced motor ensures stepless speed regulation in full range. With protection of Up and down axial, automatic stop

Characteristic: Confining pressure back pressure control uses "Precision digital piston “to make hydraulic system. Not only can exert confining pressure, back pressure, it can also be measured volume change and drainage, the change of distinguishability 1mm³ (cubic millimeter). Even if we put back pressure, burette and Volume change tube, Drainage and body sensor, artificial read operation are not required. Based on the rapid, point line, Container automatic filling, Drainage device and convenient operation, it can produce the rate such as constant pressure as required, Circulating pressure and volume change, multiple output such as linear change with time, Can be also used as flow penetration test, and other special test.
