★main purpose
The microcomputer controlled electro-hydraulic servo universal testing machine is mainly used for mechanical property testing of metal, non-metal, composite materials and products through tensile, compressive, bending, shear and other methods. At the same time, it can conduct tests and data processing according to GB, ISO, JIS, ASTM, DIN and various standards provided by users. Widely used in industries such as aerospace, machinery manufacturing, wire and cable, rubber and plastic, and building materials for material mechanics inspection and analysis, it is an ideal testing equipment for research institutes, colleges and universities, industrial and mining enterprises, technical supervision, commercial inspection and arbitration departments.
★ Performance characteristics:
1. The testing machine adopts a high-precision electro-hydraulic servo valve controlled by a microcomputer, drives a precision hydraulic cylinder, and automatically controls the test force, displacement, and deformation in multiple modes to complete the tensile, compressive, and bending resistance tests of the sample, which meets the requirements of the national standard GB/T228-2010.
2. Independent hydraulic servo loading system, using original hydraulic pump units and hydraulic valves, high-precision broadband electro-hydraulic servo valves, ensuring high precision, efficiency, low noise, and fast response of the system.
3. Use branded computers to complete the setting of experimental parameters, control of the experimental process, data collection, processing, analysis, storage, and display. The software can automatically obtain more than 30 required test data, including ReH (upper yield strength), ReL (lower yield strength), Rp0.2 (specified non proportional tensile strength), Rt0.5 (specified total tensile strength), Rm (tensile strength), E (elastic modulus), etc. It can also meet various testing requirements such as constant rate force loading and holding, constant rate deformation holding, and constant rate displacement holding.
4. Fully automatic control of test force, displacement, stress, and strain rate to achieve tensile, compressive, and bending tests on various materials.
5. This machine has comprehensive multi-layer protection functions: it has two-level protection functions of software and hardware, which can achieve various safety protection methods such as force overload protection, overcurrent, overvoltage, undervoltage, mechanical limit, etc. for the testing machine;
6. The standard configuration of the testing machine is a fully enclosed protective net, which greatly improves the safety protection for experimental operators
