1. Product Introduction:

The WDW-50 type microcomputer-controlled geotextile testing machine is specifically designed for research and analysis of building materials and their users. The main unit and auxiliary equipment of the testing machine draw on advanced technologies from both domestic and international sources, featuring an attractive appearance, easy operation, and stable performance. The computer system controls the servo motor through a speed control system via a SDA controller, which then reduces the speed through a reduction system before driving the moving crossbeam up and down via precision ball screw pairs to complete the compression performance test of samples. This process is pollution-free, low-noise, and highly efficient, with a wide speed range and adjustable crossbeam movement distance, offering broad application prospects. The machine is widely used in spring material inspection and analysis in industries such as building materials, aerospace, and mechanical manufacturing, making it an ideal testing device for spring quality inspection departments.

The machine employs a high-precision, stable servo speed control system and servo motor as the drive system, with the Sida controller serving as the core of the control system. The control and data processing software uses WINDOWS as the interface to display test force, beam displacement, deformation, and test curves on the screen. All test operations can be automatically completed via the computer using a mouse. The user-friendly design makes the test operation more convenient. Integrating all these technologies, the machine can nearly perfectly achieve closed-loop control of parameters such as test force, deformation, and displacement. It supports constant stress, constant speed, and constant displacement control modes, and allows smooth switching between various control modes.
