TD-XB Automatic Pressure Concrete Xu Transformer Introduction: The automatic pressure concrete creep apparatus is used to measure the deformation of concrete cylindrical or rectangular specimens over time under constant compressive load, that is, the compressive creep deformation of concrete. Suitable for testing the creep of concrete under unidirectional compression under constant temperature and humidity conditions. This equipment can meet the needs of concrete creep testing for design, construction, quality inspection and other departments of research institutes, colleges and universities in related industries. characteristic: 1. The automatic pressurized concrete creep gauge is controlled by a hydraulic system that simultaneously controls 3, 6, or 9 creep gauge specimen loading racks, and can independently load each specimen loading rack; 2. The lead screw of the test bracket is subjected to quenching and tempering treatment to achieve a better comprehensive effect of strength and hardness; 3. The test loading frame adopts stacked composite disc springs as energy storage and shock absorption components, with high stability, uniform force distribution, and deformation. 4. The loading pressure is set through the touch screen, and the deformation of the specimen and the temperature and humidity values of the laboratory environment are collected in real time. By setting the corresponding pressure parameters through the touch screen, the touch screen applies pressure to each creep tester loading rack through the hydraulic system. When the set pressure is reached, the pressure remains constant. When the specimen undergoes deformation due to prolonged loading, resulting in insufficient pressure, the hydraulic system automatically applies pressure to the set value and maintains constant pressure. 5. The test brackets are all equipped with bases, which, compared to other manufacturers who only rely on the contact between the end faces of three screw shafts and the ground, increases the bearing capacity of the ground and reduces the force per unit area of the ground. 6. The hydraulic pump station adopts domestic pump stations, which can operate stably for a long time; Equipped with hydraulic locking components, it can lock the oil circuit when the pressure reaches the set value, avoiding rapid pressure drop and frequent pump station start-up caused by hydraulic oil leakage from the oil tank under long-term high pressure. 7. Both the pressure acquisition system and displacement acquisition system are used, with good accuracy and durability, and are produced by domestic manufacturers; Technical parameters: Large testing force: 500kN, 1000kN (optional, can also be customized according to customer requirements) Measurement range: 0-500kN, 0-1000kN (optional, can also be customized according to customer requirements) The pressure sensor is made of stainless steel and has high anti eccentricity, overload capacity, and sensitivity. Relative pressure error: less than ± 1% Displacement sensor stroke: 5mm Displacement sensor accuracy: 0.1%, linearity of 0.05% Temperature sensor accuracy: ± 0.5 ℃ Humidity sensor accuracy: ± 3% Stacked spring component height: 300mm (stacked spring/ordinary spring optional) Test block size: （mm） 100×100×300 100×100×400 100×100×515 150×150×300 150×150×400 150×150×450 150×150×600 200×200×600 Bracket size: 750 × 750 × 2800mm Working temperature:- 20℃~+80℃
