250kN automatic tension testing system

General description of equipment:  

      The intelligent system can realize the control mode of stress rate, strain rate and displacement rate, and realize the smooth conversion among several control modes in one test; it can display the parameters of load, rate, strain and displacement in real time; it can enlarge and analyze the curve section by section; for the error of input data such as sample number and size, it can modify and calculate again to replace the original one Wrong data.

It can realize automatic batch test function. The automatic sample delivery manipulator takes the sample from the sample holder, after adjusting the position, it is sent to the measuring device to automatically measure the sample diameter at the two ends and the middle three positions of the test section, and automatically input it into the computer of the system; it automatically calculates the proportional gauge length; then it automatically sends the sample to the clamp of the testing machine for automatic clamping; the extensometer automatically clamps the test according to the calculated gauge distance or the preset gauge distance The waste sample recycling manipulator automatically takes down the broken sample and puts it back to the corresponding position of the recovery sample rack; the beam automatically returns to the initial position.

It has automatic protection function. When the test load exceeds the maximum load of the sensor; when the position and state of the sample do not meet the sample sending requirements; when the recovery device does not clamp the broken sample; when the fixture is not opened and closed effectively; when the extensometer position is wrong; and any other conditions affecting the test data or the safety of instruments and personnel, the testing machine will automatically alarm and stop.
