Electro-hydraulic testing machine HJ-9000 series

compressiontensilebending

It is mainly used for testing dynamic and static mechanical properties of various materials, parts, elastomers, shock absorbers and components. Tensile, compression, bending, low cycle and high cycle fatigue, crack propagation and fracture mechanics tests can be carried out under sine wave, triangle wave, square wave, trapezoidal wave and combination waveform. Environmental test device can also be configured to complete environmental simulation test at different temperatures. 1, testing 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 chrome electroplating, the servo actuator (cylinder) is placed under, and the cylinder piston is designed with two-way action. The sample clamping adjustment is convenient and flexible. 2, the key components: the use of international famous brands - MOOG servo valve, Germany DOLI controller, Japan not Eryue oil pump, the United States King sensor, the United States MTS displacement sensor. 3, hydraulic servo pump station: no leakage silent technology, stable pressure output, no fluctuation, low noise, good heat dissipation effect, high filtration accuracy, pressure overload, oil temperature over temperature automatic protection. 4, control mode: force, displacement, deformation PID closed-loop control, and can realize any control mode smooth and undisturbed switching.
