The WDW-SC500 microcomputer controlled relaxation testing machine is a new type of equipment for conducting relaxation tests on prestressed steel wires, PC steel bars, and steel strands. The use of microcomputer controlled experimental process, automatic data collection and processing, reduces the labor intensity of personnel and increases the accuracy of experiments, making it an ideal experimental equipment for enterprises and research institutes. The device is equipped with appropriate accessories and can also perform tensile and compression tests on other specimens.
This series of testing machines is mainly used for relaxation testing of steel strands, and can detect the uniaxial tensile relaxation strength and other characteristics of steel strands and other metal wires. It can be widely used in quality inspection departments, construction units, steel wire and steel bar production enterprises, and is a new type of testing equipment for modern building mechanics testing. Meets GB-T 5224-2023 "Steel Strands for Prestressed Concrete" and GB/T10120-2013 "Test Method for Stress Relaxation of Metals". The design of the main unit and auxiliary equipment of the testing machine draws on advanced technology from Shimadzu, Japan. It has a beautiful appearance, easy operation, and stable and reliable performance. The computer system controls the servo motor to rotate through a controller and a speed control system. After being decelerated by a reduction system, it drives the moving crossbeam forward and backward through a precision screw pair to complete the relaxation mechanical performance test of the sample. It is pollution-free, low-noise, and highly efficient, with a very wide speed range and crossbeam movement distance, and has a very broad application prospect. This machine is widely used for metal material inspection and analysis in industries such as building materials, aerospace, and machinery manufacturing, and is an ideal testing equipment for quality inspection departments.
