This electro-hydraulic servo compression testing machine adopts
imported servo valve, can realize closed loop control for force and
load keeping functions very accurately and conveniently.
In the capacity range of the machine, operator can freely change
test speed according to test requirement.
This compression testing machine is suitable for compression
strength test of cement, concrete, brick, etc. And if equipped with
suitable test fixtures, it can make test of splitting tensile test,
flexural and bending test, static elastic modulus test etc.
Compression and upset test for metal materials can be completed on
this compression testing machine. And more than one displacement or
deformation measuring device can be equipped for requirement. It is
the very testing machine for scientific research institutions,
cement quality control, industrial and mining enterprises, etc.
- Adopting high rigid four columns structure, very stable during
- High precision load cell can make sure the accuracy and precision
of test result
- Imported low voice high pressure oil pump to make a very quiet
circumstance during test. Air cooling hydraulic system allows long
working time of the testing machine.
- Adopting high integrated, powerful and high speed DSP platform,
very strongly in data process.
- Full digital and three closed loop control system is based on
self-adapting PID algorithm, which can realize digital closed loop
control for force, deformation and displacement, and the three
closed loop control can be switched freely without shock.
- High precision 24 bit data collecting system with high definition
and can be expanded to be 8 channel AD collecting.
- Communication speed is 12Mb/s, and electric board adopts 4 layer
PCB Anti-interference wiring method to avoid interference.

5. software introduction
5.1 compute auto control test procedures, software has functions of
auto zero, calibrating, no grading in full capacity and speed
adjusting. Software can measure test force, deformation,
displacement, and display test curve in real time, process test
data and print test report if connect to a printer.
5.2 display test curves of force vs time, force vs displacement,
deformation vs time, etc.
5.3 functions of constant force speed control and load value
holding, functions of displacement speed control and displacement
5.4 protecting function of sample breaking
