HUALONG|Fatigue testing machine|PWS|10~500kN - 1

Fatigue Testing Machine HUALONG PWS series are ideal components from medical devices to shock absorbers, and materials such as plastics, elastomers, aluminum, composites, steel, super alloys and more. Capable of performing tests like tension, compression flex/bend fatigue (low cycle fatigue / high cycle fatigue / fatigue crack propagation ASTM E647), fracture mechanics properties and vibration testing. The lightweight crosshead and stiff load frame components reduce load frame deflections and increase the performance envelope of the system. Servo valves offer high response and accurate control. Hydraulic service manifolds with close-coupled accumulators improve Load unit stiffness and extremely low friction actuators ensure high possible test control and resolution, making these systems suitable for both dynamic and static testing Fully self -contained test system packaged for easy relocation and Load frame on vibration isolators. Vibration isolators for quiet operation. transducers, all supported by single - platform packaging: self- aligning hydraulic grips, extensometers, pulsed, reversible p.d. unit, etc. Provision for elevated temperature testing with self-contained closed loop Hydraulic lifts and locks allow the crosshead to be easily positioned. Configure the unit to suit your needs by selecting actuator stroke length, force capacity, servo valve, and hydraulic performance combinations. All load units are fully fatigue rated. Accurate static tests can be performed on the same load unit used for dynamic test applications.

Load frame Constant pressure servo-pump The load frame is double columns framework structure, and the servo linear actuator is at the bottom. The crosshead elevating by hydraulic force, pre-tensile stress clamping and hydraulic loosening guarantee the stability and reliability of the test and meanwhile guarantee the crosshead locked during non-test status. Shape of the crosshead has the feeling of three dimensions and looks terrific. Surface of double columns is plated with chrome, which make it looks good as well as anti-abrasive. Servo linear actuator is at the bottom, in which there is a...
