Product Description:
The mainframe features a rigid gapless structure, ensuring that the testing machine exerts no impact on the ground upon the fracture of the tensile specimen.
Function and Application:
1. This machine is primarily used for tensile testing of metals and non-metals. It is suitable for fields such as metallurgy, construction, light industry, aviation, aerospace, materials, colleges and universities, and scientific research institutions, featuring a triple-loop function. It can perform stress, strain, and displacement closed-loop control methods, and can switch without impact. Its stress rate and strain rate fully comply with the national standard GB/T228.1-2010 "Tensile Testing Method for Metals at Room Temperature."
2. This machine is our new generation electro-hydraulic servo tensile testing machine. It features a four-column frame structure, utilizes bidirectional hydraulic cylinders, and achieves bidirectional tensile-compression control within a single space. Moreover, both load and deformation sensors offer full-range operation without any step-up (superior to stepping, eliminating conflicts during range conversion).
3. This equipment features multiple protection functions, including hardware and software overload protection.
4. Utilize the Puyang SMART TEST multi-digit multi-channel closed-loop control system (alternatively, the German DOLI company's EDC-220 can be used).
5. The machine features a pull-wire photoelectric encoder, offering high measurement accuracy. It not only measures and controls the piston's displacement but also gauges and controls the tensile deformation of the sample.
6. The machine utilizes servo valves in place of traditional nozzle plate-type servo valves, enhancing resistance to contamination and ease of maintenance.
7. The unit employs a bidirectional flanged load sensor, featuring anti-offset capability, high measurement accuracy, and good linearity, thus avoiding the numerous disadvantages associated with hydraulic pressure sensors that could affect the accuracy of the force measurement.
8. This machine features bidirectional hydraulic cylinders with excellent sealing, high precision, and good consistency.
9. A low-friction sealing ring is inserted between the piston and cylinder to prevent oil leakage in the hydraulic cylinder, and the joints of high-pressure hoses use a sleeve-type seal.
10. Equipped with a high-pressure internal gear pump, offering high efficiency, low pulsation, and stable pressure.
11. Win7 Chinese Edition Real-time Control Test Software, automatically collects and processes test data, displaying test data in real-time, including load-deformation curves and load-time curves. Users can print test reports in the desired format. Original data from the tensile process is stored in the default folder, allowing users to reproduce the tensile curve and reanalyze the results. The computer can export original data from the experimental process, reproduce the tensile curve using tools like Excel, and verify various parameters.
This series of products conforms to the requirements of standards such as GB/T2611-2007, GB/T16826-2008, GB/T228.1-2010, and GB/T232-1999.
