1、 Performance characteristics:

The microcomputer controlled electro-hydraulic servo testing machine is designed and manufactured according to the standards of GB/T3159-2008, GB/T228.1-2010, and GB/T 7314-2005. It is mainly used for tensile, compressive, bending, shear and other tests of metal and non-metal materials, with simple accessories and devices added. It can also test wood, cement, concrete, rubber and their products. The host adopts the method of dual column dual screw oil cylinder placement, hydraulic tightening, chain wheel transmission, oil cylinder piston clearance sealing, and nut screw pair transmission; The measurement and control system adopts the company's independently developed microcomputer controlled electro-hydraulic servo measurement and control system, which measures force with sensors and displays on the microcomputer screen; Implement various control methods such as constant velocity test force, constant velocity deformation, constant velocity displacement, load holding, and displacement holding for testing. Automatically calculate various values, display test forces, deformations, and test curves, and print test reports. Users can also edit the format of test reports themselves. Widely used in metrology and quality inspection, metallurgy and steel, machinery manufacturing, electronic and electrical appliances, automobile production, wire and cable, civil aviation, higher education institutions, research and testing institutes, commercial inspection and arbitration, technical supervision departments, building materials and ceramics, petrochemicals and other fields.
