Computer display hydraulic universal tensile testing machine bench for compression test
1. Application
Computer display hydraulic universal tensile testing machine bench for compression test adopt the cylinder under type, the structure of the four pillar and two screw , driven by hydraulic motor directly in the beam space adjustment experiment, eliminate gap structure, guarantee the accuracy of the test process of precision, is a large domestic high-end precision testing machine.Mainly used for metal, nonmetal tensile, compression, bending and shear test.Suitable for metallurgy, construction, light industry, aviation, space, material, universities and colleges, scientific research units, and other fields.Experimental operation and data processing in accordance with GB228-2010 "metallic materials at room temperature tensile test method.
2. Standards
ISO6892, BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4, ASTM E8 and BSEN standards.
3. Host Features
3.1 Adopts that fuel tank is mounted under the host, tensile test space is located above the host, compression, bending, shearing test space is located under the host, means between beam and worktable.
3.2 The structure is designed with solid four column and two screw, the whole machine has strong stability.
3.3 The host is designed all-inclusively to ensure its super strong stiffness so that it can resist micro-deformation when it is loading.
3.4 Middle beam adopts adjustable gap screw-nut mechanism, eliminating the gap and improving the measurement performance.
3.5 Fuel tank adopts gap sealed, improving the measurement accuracy and also extending service lifetime.
4. Overload protection
4.1 When the test force exceeds 2%-5% of the maximum test force of each file, overload protection, it will stop.
4.2 When the piston rises to the upper limit position, travel protection, pump motor will stop.

6. Common sense: The differences between WAW, WEW and WE series testing machines
WAW Series is computer controlled servo hydraulic universal testing machine. The space adjusting, & test
processes could be controlled by the software and the test result could be transferred to the software in the computer for further analysis. It is the most advanced series in hydraulic universal testing machines.
WEW Series is computer display manual control hydraulic universal testing machine. The space adjusting & force loading could be executed by manual control. The test result could also be transferred to the software for further analysis.
WE Series is pendulum dynamometer display manual control universal testing machine. The space adjusting & force
loading could be executed by manual control, and the test result could be shown through dynamometer.
