Brief Introduction

This series of microcomputer controlled electro-hydraulic servo horizontal tensile testing machine adopts the horizontal frame structure.The space adjustment is accomplished by pushing the moving beam of the latcher-type structure, and the precise adjustment is later accomplished by dragging the beam by the cylinder.digital controller is loaded by electro-hydraulic servo system, and adopts servo valve to complete the closed-loop control of the testing machine, with high corresponding speed and control accuracy.With strong pollution resistance and high reliability.

This equipment adopts high-precision electro-hydraulic servo pumps to control the test force and displacement (deformation) automatically in multiple modes, and completes the test parameters setting, test process control, data collection, processing, analysis and display during the test, accurate to achieve isochronous displacement control, isochronous test force control, with any test force point setting and holding function. And equipped with electro-hydraulic servo horizontal testing machine special software, can print various requirements of the test curve and test report, can choose stress-strain, test force-strain, test force-time, test force-displacement, displacement-time The test curves such as stress-strain, test force-strain, test force-time, test force-displacement, displacement-time, deformation-time, etc. can be displayed, enlarged, compared, traversed and monitored during the test in real time.

The body of the testing machine adopts double frame structure, the hydraulic cylinder is installed on the fixed beam, the sensor is directly connected with the moving beam, to perform tensile test on the specimen, which simplifies the structure of the loading head; the side of the hydraulic cylinder is equipped with a photoelectric encoder, to measure the deformation of the specimen.

The hydraulic loading system is installed on the side of the main machine, which adopts low-noise hydraulic pump unit and hydraulic valve set, high-precision AC servo motor to ensure high precision and high efficiency, low noise, fast response, and realize the automatic control of loading and commutation of the test; the sensitive pressure compensation system control makes the hydraulic system structure greatly simplified, lower noise, and basically "silent" work under non-full-load working conditions, without the need to increase the cumbersome cooling system, and no need to isolate the noise and the hydraulic system outside other rooms; the system is simple and clear.

The machine is equipped with a software package of control and data processing based on database technology. It has the functions of experimental data acquisition, processing, storage and screen display. It has the capability of LAN sharing and distributed processing of experimental data.

The testing machine adopts AC servo motor as power source, adopts advanced chip integration technology, professionally designed data acquisition and amplification and control system, test force amplification, A/D conversion process to achieve full digital adjustment.
