Description
HUT series type 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.
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 side action hydraulic tensile grips provide high gripping performance for high strength and high hardness materials without any initial gripping force.
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.
Side action hydraulic grip
·         The clamping force can be adjusted automatically according to sample dimension and material.
·         Excellent axial alignment avoids lateral loading.
·         Cylinders are inserted inside the grip body; dual direction clamping can ensure good proper alignment regardless of sample thickness varying.
·         Piston is made of alloy steel with high hardness and abrasion resistance.
·         Piston rod and piston are one-body forging. Piston is sealed with UK Hallite seal ring which can bear pressure up to 70MPa.
·         Upper and lower grip alignment is guaranteed by mechanical force with high precision and reliability. As shown above, the left and right of the piston rod respectively are connected to the rack. Two racks engage with the center gear, a rack moves to turn gear, gear will drive another rack. This is the mechanical synchronization principle.
·         Unique grip design allows clamping wide range of specimens without changing jaws frequently.
