WEW Microcomputer Display Hydraulic Universal Testing Machine
1.      Applications and Features:
WEW series of Computer Display Hydraulic Universal Testing Machine adopts the cylinder underneath type main engine, use a load cell to measure force. The machine configured import oil pump unit and oil source, clamping automatically, simple operation and if increase affix it could expand test range. This tester is mainly used for metal, plastic, concrete, cement and other non-metal materials’ tensile, compression, bending and shear test and etc. The computer can get parameter automatically, such as tensile strength, yield strength and elastic modulus E according to GB/T228 "metallic materials tensile test at room temperature method”.

3. Functions
1)Software packages
Features of the software package:
(1) Measuring the force value, deformation and displacement synchronously.
(2) Test curve real-time display
(4) Can zoom and print testing curve. Can select parameter points on the curve (yield point, elastic, etc).
(6) Can obtain metal materials tensile( pressure) strength, yield strength, δ0.2, disproportional strength, elongation strength etc.
 
2) Microcomputer system: Use the Lenovo brand microcomputer as host machine to finish the testing setting setup, data acquisition, display and print test results etc(include: main engine, 17 "LCD and large capacity hard disk); equipped with KQL-PowerTest2001 in English and Chinese version which is intelligent test software packages; Can provide standard measurement and judgment of performance parameter for all kinds of material, add up and processing the data; output various requirements of the test report and test format curve.
 
3) Computed mode: Hand valve operation, and equipped with manual control operation box, contains 6 buttons (rise,fall, upper clamping, bottom clamping, upper loosen, bottom loosen), the operation more convenient, safe and reliable.
 
4) Safety protection: Equipped with oil cylinder protection system, overload autostop system, overcurrent outostop system and emergency switch protect function.
 
4 Advantages:
(1) The main machine is using oil cylinder underneath structure. If the testing force greater than 600KN, it should use 6 pillars connect to the upper beam and working table.
(2) Adopt automatically hydraulic to clamp the specimen, not easy sliding.
(3) Adopt spoke structure loading sensor. It has advantage of high precision and stable performance.
(4) The oil pump is imported from Italia, low noise, stable oil and no impact.
(5) Hydraulic sealed with double sealing structure, effectively prevent the leakage of oil and oil leakage.
(6) Configured Clamp mouth protection board, this could effectively prevent the splint of clamp mouth scratched.
 
5. Disadvantages:
The product adopt hand valve operation, computer processing experimental data, no computer control test function, cannot realize a constant force and no constant loading function.
