500kn-2000kn Electro-Hydraulic Servo Fatigue Testing Machine
Classification :
PRODUCT DETAILS
Product Introduction:
It is mainly applicable to tests on static mechanical properties, dynamic mechanical properties, and various conventional fracture mechanical properties of metallic and non-metallic materials. By replacing fixtures, it can complete experimental research on tension, compression, high-cycle fatigue, low-cycle fatigue, fatigue cracks, etc., for materials and components.
Product Functions:
This series of products features a wide output force range, high control precision, convenient use, and high reliability. During the research and development process, the test system has absorbed international advanced electro-hydraulic servo dynamic testing machine technology and is designed in combination with the actual usage conditions of domestic users. Key components such as servo actuators, constant-pressure servo oil sources, and loading frames are designed and manufactured by our company. Key purchased components such as servo valves, sensors, and seals are all international mainstream models, which greatly improve the stability and reliability of the system. The overall performance of the testing machine is comparable to that of internationally advanced products.
Product Features:
The main machine adopts a rigid structure design with a low center of gravity. The main impact energy is released by the hydraulic unit, which effectively reduces the impact and noise when the sample is broken, resulting in small ground vibration.
The main machine adopts a double-column frame structure and a high-precision load sensor. The sensor has a reasonable structure, excellent performance, high measurement accuracy, and good linearity. The main machine features high rigidity and strong resistance to lateral forces.
The load has the characteristic of no range division throughout the entire process, with superior performance.
The upper-mounted load sensor ensures zero additional resistance during tensile tests.
The hydraulic system is equipped with high-quality brand hydraulic components and accessories, achieving no leakage and no pollution of the system.
This product uses an original imported servo valve, which has fast response, high control precision, improved pollution resistance, and is easy to maintain.
It adopts a full digital closed-loop control system, which can meet the requirements of test force and displacement control. Control modes can be arbitrarily combined and switched smoothly.
