The electro-hydraulic servo long column testing machine is used for compressive testing research of civil engineering structures, providing high accuracy and convenience for compressive testing of concrete materials, metal materials, non-metal materials (including composite materials and polymer materials) and their combinations, as well as structural components.
The electro-hydraulic servo 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, with microcomputer control 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 computer timely control of the test process, display of 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. 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.
