Machine structure: The mainframe, servo oil source, and measurement and control computer are integrated in design, with the characteristics of small footprint;
Measurement and control system: It is composed of oil tank, servo oil pump, control valve group, sensor, servo controller and control software, computer and other components, with high control accuracy and good reliability;
Servo oil pump: It is composed of servo motor and high-pressure oil pump, with the characteristics of fast response speed, wide speed adjustment range, low noise, etc.;
Space adjustment: The hydraulic bidirectional oil cylinder on both sides is used to adjust the space. Compared with the traditional ladder screw drive, it has the advantage of fast adjustment speed and greatly improves the detection efficiency;
Shock absorption system: The equipment is equipped with a strong shock absorption system, which does not require foundation or fixation. It has the advantage of no vibration after the sample is broken, avoiding the need for re-construction of the laboratory;
Test accuracy: The mainframe structural parts are processed by precision machining center, servo hydraulic control The system distributes the flow, and the high-precision spoke-type sensor measures the force, ensuring the 0.5-level test accuracy of the whole machine, which is better than the national standard;
Simplicity: The structure of lower stretching and upper compression greatly facilitates the tensile test of metal materials;
Working noise: The brand ultra-quiet oil pump is selected, and the servo motor is controlled, which is almost noiseless during operation;
Specimen clamping method: hydraulic clamping, easy to operate;
Safety protection: The tension and compression space is equipped with a high-toughness protective net, which is safe and beautiful;
Equipment in place: There is a forklift space at the bottom of the equipment, which has the advantages of convenient positioning and later adjustment. The upper beam can be lowered in height, and the equipment can easily pass the 2.2-meter height limit;
Equipment maintenance: The open beam jaw seat is easy to maintain and operate. There is an oil discharge port at the bottom of the equipment, which is convenient for the later replacement of hydraulic oil. The factory is equipped with a high-power industrial-grade vacuum cleaner as standard, and it can be cleaned after the test is completed;
