XLYW-20000F Electro-hydraulic Servo High-performance Long Column Testing Machine

The XLYW-20000F electro-hydraulic servo high-performance long column testing machine adopts a bottom mounted oil cylinder and a four screw structure host, with a continuously adjustable testing space. It adopts a multi-channel electro-hydraulic servo control system, and is controlled by a microcomputer to coordinate hydraulic loading, automatic continuous and stable loading, automatic load holding, automatic data collection and storage, curve drawing, automatic printing of test reports, and timely computer control of the test process, display of test force and test curves. It is simple, reliable, and easy to operate.

Fully digital electro-hydraulic servo closed-loop control, data processing, and data analysis integrated. This testing machine is mainly used for compressive, bending, and shear tests of specimens such as bridges, large structural components, concrete, metal materials, and metal structural components. It can draw time test force, time displacement, and displacement test force curves according to the testing requirements and automatically process the test data. It is an ideal testing equipment for transportation, building materials, metallurgy, aviation, aerospace, universities, scientific research units, etc.
