The YJW-30000F microcomputer controlled multifunctional long column pressure testing machine adopts a cylinder down type and a four screw structure host, with a continuously adjustable test space. It adopts a multi-channel electro-hydraulic servo control system, and the microcomputer controls the coordination of hydraulic loading, automatic continuous and stable loading, automatic load holding, automatic data collection and storage, curve drawing, automatic printing of test reports, and timely control of the test process by the computer, displaying the test force and test curve. It is simple, reliable, and easy to operate.
Fully digital electro-hydraulic servo closed-loop control, data processing, and data analysis integrated. It is mainly used for testing the mechanical properties of finished rubber bearings for highway bridges (compression, shear, and corner), compressive strength tests of concrete specimens and concrete structural components, as well as compressive strength tests of metal materials and metal structural components. This testing machine can draw time test force, time displacement, displacement test force curves and automatically process test data according to testing requirements. It is an ideal testing equipment for transportation, building materials, metallurgy, aviation, aerospace, universities, research institutions, and other fields.
