Equipment Overview:
The micro-computer-controlled electro-hydraulic servo testing machine adopts a double space structure under the cylinder，Wherein: the stretching space is between the upper beam and the lower beam，The tensile test of the sample is mainly carried out.The space between the test bench and the lower beam is compressed，The test of compression, bending and shear of the sample can be realized,，Both the stretching space and the compression space can be automatically adjusted by rotating the lead screw to drive the lower beam up and down。
The testing machine is mainly used for tensile, compression, bending, shearing and other tests of metal materials. Equipped with corresponding fixtures, it can be used for tensile, compression, bending, shearing, bending and other tests of other types of samples。
The closed-loop servo control system composed of electrical controller, servo valve, load sensor, displacement sensor, extensometer and computer can control the test process automatically and accurately, and measure test parameters such as test force, displacement and deformation automatically。
The testing machine can realize the test of equal rate loading, equal rate deformation and equal rate displacement, and can realize the control of force, deformation and displacement in one test, and the control can be smoothly converted between each control。
The test parameters can be automatically controlled and the test results obtained by computer acquisition and software processing。The test curve and test result are displayed in real time by the microcomputer screen, and the test report and test curve can be printed。
