Machine structure: The main engine, servo oil source and measurement and control computer are designed in a split type;
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 and low noise;
Space adjustment: The trapezoidal screws on both sides are used to achieve the rise and fall through the forward and reverse rotation of the motor, with a simple structure;
Beam structure: Semi-enclosed beam structure, the rigidity is greatly enhanced:
Test accuracy: Main engine structural parts It is processed by precision machining center, servo hydraulic control system distributes flow, and high-precision spoke sensor measures force, ensuring the 0.5 level test accuracy of the whole machine, which is better than the national standard;
Noise: Select brand ultra-quiet oil pump, servo motor control, almost no noise during operation, improving user experience;
Specimen clamping method: hydraulic clamp method is adopted, which is easy to operate;
Safety protection: high-toughness protection net is configured in the pulling and pressing space, which is safe and beautiful;
Equipment maintenance: open beam jaw seat, easy maintenance and operation, and an oil discharge port is provided at the bottom of the equipment to facilitate the replacement of hydraulic oil later;
