Servo-Hydraulic Universal Testing Machine 600kn (HUT605D)

Description
HUT series type D 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.
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: 2/4 columns, servo-controlled hydraulic
Capacity: 600kN, 1000kN, 2000kN
Test Space: Single zone
Typical specimens: Fasteners, rebar, chain, welds, castings

Features
Load frame
1. Single zone design ensures all types of tests finish in one space. Compact and reasonable design is ergonomic and effectively reduces labor intensify.
2. Upper actuator features excellent axis alignment, good shock absorption and easy to adjust test space.
3. Advanced wedge type hydraulic tensile grips provide high gripping performance for high strength and high hardness materials.
4. 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.
5. Robust and high-accuracy guidance protects cylinder from lateral force, improving the working life of sealing components.
6. "I" shape force transducer features excellent linerity and stability with ultra measurement accuracy.
7. Nemicon encoder provides with high accuracy of displacement measurement and control.
8. DDV D633 MOOG servo valve offers fast response and high-accuracy control, and easy to maintain.
9. Equipped ABB motor features high efficiency, energy-saving, high start-toque, good performance, low noise, low shaking, high reliability and easy to maintain.

Main cylinder
· Piston rod is Nickel and Chrome plated. Plating thickness can reach 0.1mm with strong anti-corrosion and anti-wearing ability.
· Extra thick rod ensures high stiffness to resist lateral loading.
· Piston and rod are one-body forging with strong impact resistance.
· Sealing components are Hallite U shape and double sealing ring, ensuring zero leakage.
· Hallite guidance wearing ring is applied to ensure high resistance to lateral force and low friction.
· Main cylinder matching with differential circuit allows fast return of piston.
· Zero clearance and pre-loading connection between piston rod and upper grip guarantees high reliability.
· WANCE uses most advanced Piston / guide sleeve copper melting process as wearing ring, with service life five times than polymer material.

Hydraulic power unit
· Equipped with SUN Cartridge logic valve in the hydraulic system of the equipment, it can be smart regulation of system pressure. The pressure servo technology can guarantee that the system pressure is always only higher than the cylinder pressure 1MPa, when the test force is low, the pump output pressure is lower, when the test force increases, pump output pressure increases the proportion too.
· The differential pressure is adjustable to ensure no shaking during test, thus saving energy and reducing heating
· Low noise: NACHI Japan gear pump, combined with our technology of HPU production, its noise is not more than 70dB, improving the working conditions of workers.
· Easy installation and maintenance: The hydraulic unit is designed with semi-open structure. Rear cover opens two doors, easy maintenance and parts replacement.
