Computer Controlled Electrohydraulic Servo Compression Testing Machine
Ⅰ Main function&characteristics
1. Using computer controlled high precision electrohydraulic servo valve to control test force and displacement, and make compression test, in line with national standard GB/T50081-2002 Test Method of Mechnical Property for Common Concrete.
2. Its main machine adopts four-column structure, underneath type oil cylinder, which is easy for operators to install and uninstall samples, with good stability.
3. Its loading system adopts hydraulic servo valve to ensure system high accuracy, high efficiency, low noise and quick response.
4. Using computer control display system to finish such operations as test parameters setting, control, data acquisition, processing, analysis, storage and display, accurate control and measurement.
5. Equipped with special software for testing machine, it can make statistics and processing to test data and then printout various test curves and test reports. It has functions of curve enlargement, comparison and traverse, intelligent, convenient.
6. Self-building strong test database, which can be saved, queried and called any time and can realize transmission and transformation.
7. Convenient manual open-loop control function, auto-manual, easy to operate, quick, efficient.
