Servo Hydraulic Universal Testing Machine 1000kN single test space for rebar Φ 15~ Φ 55mm HUT106D
HUT106D servo-hydraulic universal testing machine is designed with top mounted cylinder. Single test space is eaiser to access and operate the machine.
Upper actuator allows great axis alignment, good shock absorption and simple to adjust test space.
Compact and reasonable design is ergonomic and effectively reduces labor intensify.
Advanced wedge type hydraulic tensile grips offer high clamping performance for high strength and high hardness materials.
Long travel double-acting cylinder can satisfy different specimen size.
One-body forging piston and rod, and imported sealing components, ensure perfect sealing, high accuracy and repeatability.
Strong and precise guidance protects cylinder from lateral force, improving the working life of sealing components.
“I” shape force transducer features excellent linerity and stability with ultra measurement accuracy.
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.
Low heating and good cooling: The unique pressure differential servo control technique makes the system heat significantly reduced. The hydraulic unit is designed with semi-open structure and air-cooling device. Cooling devices can start automatically or manually. The air-cooling motor automatically starts when the temperature reaches the preset value of oil temperature gauge, making the system in high temperature environment continue to work normally. The whole system heating power is 2kW.
High filtration precision: triple filter, the particle size is less than 5 microns before entering the servo valve, improving the service life of the servo valve and control accuracy, easier to maintain.
Pressure overload protection: when the pressure exceeds the system rated pressure, relief valve will begin to overflow, to ensure the security of the entire system.
Seal method: the hydraulic lines from the tubing to the connector are equipped with Eaton products from USA. Piping lines are sealed with high-pressure hose sleeve type Cone fittings with excellent sealing performance, which can be repeated assembly and disassembly. Cylinder piston rod and piston seal are used with British Hallite patented Hythane U- seals and dust ring , at the same time with Hallite high anti-lateral pressure and low friction rate of large-size guide ring , offering high ability to resist lateral force, thus to ensure cylinder of zero leakage and long service life.
The advantages of the HPU: HPU consists of 25MPa high-pressure part and 50MPa super high pressure part. The main cylinder working pressure is around 25MPa and the clamping cylinder working pressure is around 48MPa. Only one motor drives oil pump. Through the booster to gain extra-high pressure, thus with lower noise.
The system has two sets of differential circuit. One is for main cylinder, so that after the end of the test, the main cylinder piston can faster return to improve work efficiency. Another is for the clamping cylinder. Clamping cylinder allows fast and low pressure gripping the specimen. Only after samples are fully clamped, extra-high pressure can be supplied, avoiding damaging sample because of too high clamping force. After specimen is broken, high pressure will be automatically released. This design fully takes the efficiency and operational safety into account.
