WEW-300B Computer Screen Hydraulic Universal Testing Machine

Applications:
It adopts hydraulic power pack to drive the piston in the oil cylinder to provide testing load. By using load cell and photoelectric encoder, the computer is timely showing the testing parameters like testing load, piston stroke, deformation of specimen and various kinds of testing curves etc.
This machine is servo control mode and the computer with strong function software does data processing and issues the test reports.
The software based on Windows system is able to make automatic calculating of test results, i.e. tensile strength; upper / lower yield strength, Non proportional stress point etc. Report creation function makes it is very simple to make testing report in needed format. It is necessary inspect device in the filed of steel and iron factory, the laboratories,machinery etc

Load frame
Rigid four-column & two -lead screw construction & compact design
Dual workspace design: Upper for tension, Lower for compression or bending tests
Movable lower crosshead providing exceptional ease of operation
Accurate force measurement through precision load cell
With open front hydraulic wedge grips for easy change of inserts and specimen loading
Integrated displacement photoelectric encoder
Cylinder mounted at the bottom of the machine
Overload protection: When the testing load is over 2%-5% of Max. Load, the system will unload.
Stroke protection: When the ram arrives at the upper limited position, the motor of oil pump will stop.

Control Unit:
1. Constant speed piston stroke control:
·Control range: Ram stroke speed
·Setting range:0.5~50mm/min
2. Constant speed load control:
·Control range:2~100%of full scale load
3. Displacement-keeping control
4. Load-keeping control
5. Constant speed strain control range:
·Range: 5~100% of full scale strain
6. Emergency shut down button & over load protection (auto stop) function equipped and return to the specified position automatically.
7. Control mode of operation: Auto/Manual function changeable
8. Automatic endpoints: The tester stops automatically while specimen breaks
9. Display of testing parameters: Value and real-time curve (Load and Stroke), available to display and switch from computer. Also the elongation can be calculated.

Featurers
1. Load:adopting load cell to ensure high accuracy, reliability and consistency;
2. Displacement:adopts optical encoder with high accuracy and stability;
3.Strain:Adopt high accuracy electronic extensometer
4.Compact structure: The machine has four column and two screw with strong stiffness;
5.Clamp automatically: uses hydraulic grips with reliable holding;
6.Multi-protection: protection of over-load by software and hardware; position-limited protection of piston and lower crosshead;
7.Test data: uses Access, Excel and other such kind software
8. It is servo control machine for load, displacement and deformation.
9. The load frame structure is 4-column and 2-lead screw with high stiffness.
10. Use load cell to test load, use encoder to measure the displacement, use digital extensometer to test deformation.
11. Software is based on Global Standards, such as CE, ISO, GB, ASTM, BS, JIS and EN etc
