1. This machine has three closed-loop functions, that is, it can control the stress, strain, and displacement closed loop, and can perform collision-free switching. The stress velocity and strain rate are in full compliance with the national standard GB228-2010 "Metal Tensile Test Method" and other metal tensile test standards. Fully meet the requirements of GB/T2611 "General technical requirements for testing machines" and GB/T16826 "Electrical and liquid servo universal testing machines".
2. This machine is a new generation of electro-hydraulic servo tensile testing machine of our company. It adopts four-column frame structure and adopts bi-directional cylinder to realize two-way control of tension and pressure in one space, and it has the whole process regardless of load or deformation sensor. No division (excellent scores, avoiding conflicts during range conversion). The main performance is: the whole process has a unique resolution.
3. This device has multiple protection functions, hardware and software overload protection, oil temperature over temperature alarm and high oil pressure safety protection.
4. Adopt Hualong Test Instrument Co., Ltd. Auto CTS-600 full digital multi-channel closed-loop measurement and control system (also can use German DOLI company EDC-220).
