In the fields of power transmission and transformation engineering, large bridge construction, marine engineering, and lifting and hoisting, the tensile mechanical properties of insulators, rigging, anchor chains, steel strands, and large structural components are directly related to the safety and reliability of the project. The microcomputer controlled horizontal tensile testing machine series of Jinan Xinguang Testing Machine Manufacturing Co., Ltd. provides high-precision and fully automatic testing solutions for the tensile performance testing of ultra long specimens and ultra large tonnage materials.
Traditional vertical tensile testing machines are limited by space and cannot meet the tensile testing requirements of ultra long specimens such as insulators, steel strands, and rigging. The Xinguang horizontal tensile testing machine adopts a horizontal frame structure, which completely solves the problem of difficult clamping of ultra long specimens. It strictly follows national and industry standards in design and has the following outstanding advantages:
1. Ultra large tonnage bearing capacity, suitable for multiple specifications: In response to the testing needs of different specifications, Xinguang can provide various tonnage models such as 500kN, 1000kN, 2000kN, and even 5000kN, to meet the tensile performance testing of various products from disc-shaped suspension insulators to rod-shaped pillar insulators, from steel strands to large rigging. The host adopts a horizontal frame structure with strong rigidity and high stability, ensuring the authenticity and reliability of test data during large tonnage loading.
2. Ultra long test space, easy to handle long specimens: The test space can be customized according to user needs, with a test space of more than 10 meters, fully meeting the clamping requirements of ultra long specimens such as insulators, steel strands, anchor chains, etc. The mobile crossbeam adopts electric drive, which can freely adjust the position of the test space, making the operation convenient and efficient.
3. High precision measurement and control system, non graded throughout the entire process: equipped with high-precision load sensors and displacement measurement systems, the accuracy of the test force indication is better than ± 1% (level 1 accuracy), the effective measurement range covers 2% to 100% FS (non graded throughout the entire process), and the load measurement resolution is as high as 1/± 500000F.S, ensuring accurate measurement throughout the entire process. The displacement measurement resolution is as high as 0.001mm, and the deformation measurement range is 0.2% -100% FS.
4. Dual station or multi station collaborative loading: For special testing requirements, the equipment can be configured with a dual station or multi station collaborative loading system to achieve synchronous testing of multiple samples or simulation of complex stress states. The servo control part adopts digital DSP technology to achieve closed-loop control of force, displacement, and deformation, with stable and reliable control performance.
5. Fully automatic closed-loop control, intelligent loading: using imported servo motors and precision screw pairs or electro-hydraulic servo loading methods, with a wide speed range and fast response speed. The control system supports multiple control methods such as constant rate test force, constant rate stress, and constant rate displacement, and PID parameters can be adjusted online. Real time display of force displacement curve during the experiment, automatic calculation of key indicators such as test force, tensile strength, and elongation at break, and automatic generation of testing reports that meet standard requirements.
6. Multiple security protections and user-friendly software: The device is equipped with multiple security measures such as overload protection, overcurrent protection, limit protection, emergency stop button, etc. The measurement and control software independently developed by Xinguang supports automatic drawing of test curves, traceable data, and supports exporting reports in various formats such as Word, Excel, PDF, etc., meeting the requirements of the laboratory quality management system.
The Xinguang horizontal tensile testing machine fully complies with the following national standards and industry specifications:
-GB/T775.3-2006 "Test Methods for Insulators Part 3: Mechanical Test Methods"
