Hot-selling Hydraulic Grip - Electro Hydraulic servo structure dynamic fatigue testing machine – Enpuda Detail:

APPLICATION AREA

The microcomputer-controlled electro-hydraulic servo structure dynamic fatigue testing machine is mainly used to test the dynamic and static mechanical properties of metal, non-metallic materials, composite materials, steel rails and other products.

Enpuda fatigue microcomputer-controlled electro-hydraulic servo fatigue testing machine is flexible and convenient to operate. The moving beam rises, falls, locks, and sample clamping is completed by button operations.

It adopts advanced hydraulic servo drive technology to load, high-precision dynamic load sensor and high-resolution magnetostrictive displacement sensor to measure the force value and displacement of the sample.

The all-digital measurement and control system realizes closed-loop control of force, displacement, and deformation. The test software adopts English operation interface, powerful data processing capabilities, and automatic storage, display and printing of test conditions and test results.

The testing machine is an ideal cost-effective fatigue testing system for scientific research institutes, metallurgical construction, national defense industry, colleges and universities, aerospace, rail transit and other industries.

Performance features / advantages

1. Test machine host: column, base, beam constitute a closed frame structure, frame stiffness, no reverse clearance, good stability. The outer surface of the column is treated with hard chromium plating. The servo actuator (oil cylinder) is installed on the upper part, and the piston design of cylinder with two-way action is adopted. The sample clamping adjustment is convenient and flexible.

2. Key components: adopt international famous brands such as MOOG servo valve of the United States, DOLI controller of Germany, Buer oil pump of Japan, Shiquan sensor of USA, displacement sensor of MTS company of USA, etc.

3. Hydraulic servo pump station: adopt no leakage mute technology, stable pressure output, no fluctuation, low noise, good heat dissipation effect, high filtering accuracy, automatic protection of pressure overload and oil temperature over temperature.

4. Control mode: force, displacement and deformation PID closed-loop control, and can realize smooth and undisturbed switching of any control mode.

5. Test software: it is suitable for operation under Windows test platform. With the control system, it can control the test system to complete all kinds of dynamic and static mechanical property tests, such as metal tensile, compression, bending, low cycle and metal fracture mechanical tests, and independently complete various test management, data storage, test report printing and other functions.

6. Test waveform: sine wave, triangle wave, square wave, random wave, sweep frequency wave, combined waveform, etc.

7. Protection function: it has alarm and shutdown functions such as blockage of oil circuit, over temperature, low liquid level, overload of hydraulic system, overheat of motor, preset fatigue times and fracture of test piece.
