Servo Hydraulic Dynamic and Fatigue Testing System NSHS-100 Catalog

FEATURES

• ⇋ The host employs a four-column frame structure with hydraulic lifting, clamping, and elastic release for crossbeam stability during tests
• ⇋ Column surfaces are electroplated with hard chromium for enhanced wear resistance
• ⇋ Crossbeam movement is enhanced with HAWE hydraulic components with ultra-high pressure and zero leakage, ensuring reliability
• ⇋ Integrated with high-precision LVDT displacement sensors to measure experimental displacement
• ⇋ A precision oil filter with 0.003mm filtering accuracy and a dedicated two-stage electro-hydraulic servo valve enhance actuator performance
• ⇋ The modular servo linear actuator offers low damping, high response, and a long lifespan
• ⇋ A hydraulic buffer zone at the amplitude limit prevents damage from running out of control
• ⇋ Supplied with high-precision load sensor is used to measure test loads, with a pre-stressed ring for improved dynamic response
• ⇋ Conveniently designed sample clamping, beam movement, and emergency stop button stations enhance usability
• ⇋ Utilizes bidirectional clamping for sample coaxiality regardless of thickness changes
• ⇋ The piston, made of alloy steel, undergoes high-frequency quenching for durability and wear resistance
