Electro-Hydraulic Universal Tester 1000kN / Servo 2000kN555

Product Features & Attributes
This series of electro-hydraulic/electro-hydraulic servo universal testing machines is mainly used for tensile, compression and bending tests of metal materials, equipped with cold bending accessories for metal material process testing. Suitable for research institutions, capital construction units, metallurgy, machinery manufacturing and university laboratories.

Working Principle: The working cylinder is bottom-mounted. High-pressure oil pump supplies oil to the cylinder, driving the piston to move the worktable and upper beam upward for tensile or compression tests. Tensile tests are performed between the upper beam and moving crossbeam; compression tests between the worktable and moving crossbeam. Test space adjustment is achieved by moving the crossbeam up and down via the drive mechanism.

Two Control Modes Available:

• Electro-Hydraulic: Manual oil supply valve controls load and loading speed, digital force display, intuitive and cost-effective.

• Electro-Hydraulic Servo: Computer closed-loop control of servo valve, automatic control of loading speed, pressure holding and unloading. Can connect to PC software for data acquisition, processing and printing, with high automation.

Structure:

• Main unit: Height-adjustable support frame (base, screws, moving crossbeam) and working frame (cylinder, piston, worktable, guide columns, upper beam).

• Dynamometer: Digital display, pressure sensor, microcomputer and printer.

• Hydraulic control system: High-pressure oil pump, oil supply/servo valve, return valve, working cylinder, etc.

• Safety devices: Piston stroke limit switch, instrument overload protection (auto stop at 3% over max load).

Technical Features:

• Bottom-mounted cylinder, hydraulic loading, stable operation.

• Sensor force measurement, digital display, Class 1 accuracy.

• Loading speed indicator window for easy adjustment.

• Moving crossbeam only for test space adjustment; never move during loading/unloading.

• Cold bending accessories for bending and cold bending process tests.

• Servo model connects to PC for automatic control, data acquisition and report printing.

Applications:

• Research institutions and university laboratories

• Capital construction units and quality inspection stations

• Metallurgy and machinery manufacturing

• Metal material manufacturers

Operation Procedure:

1. Turn on power, display and oil pump, raise piston a short distance.

2. Select and install fixtures according to specimen, clamp specimen.

3. Set test parameters, slowly open oil supply valve (or servo valve auto control) for loading.

4. After specimen fracture, close oil supply valve, stop pump, record data.

5. Open return valve to unload, remove specimen, clean equipment.

Precautions:

• Never move crossbeam during loading or unloading.

• If pump stops suddenly, immediately open return valve to release load.

• Regularly check chain tension and machine level.

• Use high-quality anti-wear hydraulic oil (N46-N100), keep clean.

• Cover with machine coat when not in use.
