The host of this series of universal testing machines from Liangong mostly adopts a downward mounted oil cylinder, chain transmission, and hydraulic clamping. The tensile space is located above the host, and the compression, bending, and shear testing spaces are located between the crossbeam and the worktable in the host.
Main technical parameters:
1. Maximum test force: 300KN-3000 kN;
2. Test force measurement range: 2% - 100% full range;
3. Accuracy of test force indication: ± 1%/± 0.5%;
4. Maximum piston movement speed: 50 mm/min;
5. Piston stroke: 50 mm;
6. Displacement measurement resolution: 0.01 mm;
7. Displacement measurement indication accuracy: ± 1% or ± 0.5%;
The control and measurement system of the Liangong WAW series testing machine has absorbed various advanced experiences in current testing machine control, and adopts a fully digital electro-hydraulic servo closed-loop control and measurement system to achieve control functions such as constant velocity stress, constant velocity strain, constant velocity test force, constant velocity displacement, test force maintenance, displacement maintenance, etc. It has multiple layers of protection function, which can achieve various safety protections such as overload, overcurrent, overvoltage, undervoltage, overspeed, limit, etc. for the testing machine.
Liangong WAW series computer control electro-hydraulic servo universal testing machine is widely used in metallurgy, construction, light industry, aerospace, colleges and universities, scientific research institutions and other fields with its main advantages of beautiful appearance, advanced technology, excellent performance and stable quality.
