1. Application of electro-hydraulic servo long column pressure testing machine:
YAW-F series microcomputer controlled long column pressure testing machine is mainly used for concrete, super concrete, mortar, components, rocks, pipe piles, building materials, various metals, non-metals and composite materials, engineering plastics, wood, cement, etc. Compressive testing and research of specimens can also be used for compressive testing and research of large components. The addition of reverse bending beams can also be used for bending tests of concrete beams or other long members. Add supporting test aids, which can also be used for jack testing; concrete beam vertical compression testing; metal pipe, seamless steel pipe, non-ferrous metal pipe flaring test, etc.
2. Features of electro-hydraulic servo long column pressure testing machine:
1. The precise automatic control and data acquisition system realizes the fully digital adjustment of the data acquisition and control process.
2. It has multiple control methods such as automatic load holding, stress, strain control, cycle control and self-programming control.
3. The four-column screw structure, the hydraulic cylinder is placed down, large space, high rigidity, and good stability.
4. Servo measurement and control system, realizing automatic loading at constant rate, maintaining constant test force, cyclic loading and unloading.
5. According to GB, ISO, JIS, ASTM, DIN, BS and other national standards and international standards for testing and provide testing data.
6. Automatically complete the detection parameters such as the greater bearing capacity and strength of the material.
7. The servo measurement and control system realizes automatic loading at a constant rate, maintaining constant test force, and cyclic loading and unloading.
8. Multiple protection functions: oil cylinder limit protection; hydraulic system overload and overflow protection; test force overload protection; over-current and over-voltage protection; 9. safety protection; operation prompt guide protection; automatic protection at the end of the test.
