Servo-Hydraulic Universal Testing Machine Series DP

RoboTest series DP servo-hydraulic universal testing machine is designed with up-mounted actuator structure. Bidirectional differential cylinder provides bidirectional control of tension and compression in one single space. Advanced side action hydraulic tensile grips provide high gripping performance for high strength and high hardness materials without any initial gripping force.

Clearance-free structure and actuator up and down to adjust the test space offers easy operation and high efficiency. This machine is mainly used for tensile test of metallic materials. It provides closed loop control of constant force, constant displacement and constant extension, smoothly switching among them.            

Test results can be automatically calculated and be able to printed and exported.

Load Frame Configuration: 4 columns, servo-controlled hydraulic

Capacity:  600kN, 1000kN, 2000kN

Test Space:  Single zone

Typical specimens:  Fasteners, rebar, chain, welds, castings

 â–º  Single zone design ensures all types of tests finish in one space. Compact and reasonable design is ergonomic and effectively reduces labor intensify.

â–º  Upper actuator features excellent axis alignment, good shock absorption and easy to adjust test space.

â–º  Advanced wedge type hydraulic tensile grips provide high gripping performance for high strength and high hardness materials.

â–º  long travel double-acting cylinder can accommodate different specimen size. One-body forging piston and rod, and imported sealing components, ensure perfect sealing, high accuracy and repeatability.

â–º  Robust and high-accuracy guidance protects cylinder from lateral force, improving the working life of sealing components.

â–º  “I” shape force transducer features excellent linerity and stability with ultra measurement accuracy.

â–º  Nemicon encoder provides with high accuracy of displacement measurement and control

â–º  DDV D633 MOOG servo valve offers fast response and high-accuracy control, and easy to maintain.

â–º  Equipped ABB motor features high efficiency, energy-saving, high start-toque, good performance, low noise, low shaking, high reliability and easy to maintain.
