Main function &features:
1. This series machine adopt microcomputer control full digital broadband electro-hydraulic servo valve to drive high precision hydraulic cylinder, auto control to test force, displacement, deformation, and finish tension, compression, bending test. This series machine comply with national standard GB/T228-2002 Method of Tensile Test of Metallic Materials At Room Temperature and GB/T3159-92 Hydraulic Universal Testing Machine. If equipped with accessories, can perform mechanical property test for high strength bolt, chain, steel wire and other materials.
2. The main machine adopts underneath hydraulic cylinder; the power to adjust test space and transmission devices are installed at the bottom of the main machine, running stably; upper and lower jaw base are open structure, easy to clamp specimen.
3. independent hydraulic servo loading system, using high precision broadband electro-hydraulic servo valve to ensure system high precision, high efficiency, low noise, quick response; using independent hydraulic clamping system to ensure system run stably and low noise, and no-slipping of specimen during test.
4. computer control, completely realizing three closed-loop control to test force, displacement, strain, test procedure control, data acquisition, processing, analysis (test data including: elastic modulusE, tensile strength Rm, upper yield point ReH, ReL etc.), accurate, reliable.
