steel wire rope tensile testing machine
1. Application :
WAW-L series Computer Control Eletro-Hydraulic Horizontal Tensile Testing Machine adopting hydraulic drive, electro-hydraulic servo control technology, computer data acquisition and processing, enabling closed-loop control and automatically test high-precision test equipment,mainly composed by the host, oil source (hydraulic power source), measuring and control systems and test grip, the maximum test force 300kN with 1 class test accuracy . Meet the test standard ASTM E4. Can test specimens like wire, cable, connecting rod, steel wire, steel cable, steel link, metal chain, chain assembly, spring, webbing, rope, anchor chain, hook, piping and metal fasteners are testable
2. Host
It is a suitable for testing long sample to meet requirement specified in the national standard tensile and compression tests, the process can be qualified performance verification tests of materials or products .
The machine host is frame structure, between and the front end and the rear end of the frame is tensile space, through oil cylinder moving back and forth adn pin position to adjust the test space .
3. oil source system
whole cabinet oil source control cabinet composed of the pump stations, electro-hydraulic proportional valve, data acquisition systems, computer and other components integrated, simple and convenient at operation, maintenance, protection, transportation
Seals, tubing using well-known brand, to ensure lasting without no leakage
Power source using Italian MARZOCCHI gear pump, ensure long-term use system pressure stable, smooth cylinder operation. Systems designed with the energy-saving, reliable, safe and environmentally friendly, the oil supply system components are used in environmental compliance, low noise level during operation.
The system adopts closed loop control. Directional valve and sequence valve are using well-known brands, fast response, high sensitivity. Real-time monitoring of load, displacement, deformation, etc., with traceability, with mobility, adjustability and other features, enables automatic precise control. testing machine is currently the most advanced technology, the most superior quality, most high-end configuration hydraulic proportional servo control system.
4. Measuring and control system
The loading measuring unit is a high-precision load cell, displacement measuring elements using high resolution guyed displacement sensor. Test controlleris full digital closed-loop control system which is designed for material testing machine. You can select various settings and testing procedures, can automatically and precisely control the testing process and automatically measure the various stages of test parameters, ensuring high-precision tests.
Special test software developed and used under windows platform, ensuring easy operation and versatility of test, test data automatic processing, preservation, testing process curve real time displayed on the monitor. Can achieve constant force loading, constant deformation loading, constant displacement loading, constant strain and other test methods. Can achieve force, deformation, displacement, strain segmented control, automatic smooth switching between control in one test. Test parameters by computer acquisition and software processing can automatically control the testing process and automatically determine the test results. The monitor displaying test curves and test results in real time, test report and test curves printed by the printer.
