Hydraulic Automatic Multi-function Rock Dynamic-static Testing System

characteristic：
1.high degree of automation and efficiency, sealling,injecting, and ejecting automatically of pressure chamber, w/o manual manipulation .
2.it will finish 6-8pcs testing per one staff by each day.
3.the rate of closed-loop of all channel is 10khz, loading include stress, strain, displacement and arbitrary switching control, it also available for subsection control of stress, strain, displacement, axial direction during testing.
4.multiple protection: over load, overvoltage, overheating and misoperation. Pressure chamber adopts the newest double-deck intertwine structure, which enhanced the safety and the explode will never happen.
5.built-in pressure chamber of load sensor would eliminate the affect of friction. Besides, improving the measurement accuracy of axial load.
6.the controller can connect to usb, hddd and sdhc directly, data can be stored in the controller external device directly, pc as well. Data double insurance to prevent computer crashing and data losing.the the controller can independent working and  run stably for a long time.there is any influence while the computer crashed.

function:
• uniaxial compression of full stress-strain test/dynamic cycling test
• triaxial compression of full stress-strain test/dynamic cyclic test
• high temperature and pressure test
• rock rheology test
• brazil split test
• acoustic emission test
• hydraulic fracturing test
• true triaxial composite path of full stress-strain test
• true triaxial rock burst unloading test
• seepage test
• direct shear/variable angle shear test
• it can be customized according to the requirements of complex  path testing later
