WDL-300 Microcomputer Controlled Electronic Horizontal Tensile Testing Machine

1. Product introduction

WDL-300 microcomputer controlled electronic horizontal tensile testing machine, the principle of electronic universal testing machine, servo motor drive, measurement and control accuracy is twice higher than the ordinary horizontal tensile test, can meet GB, ISO, JIS, ASTM, DIN and other international standards and industry standards; It can be used to test the tensile strength of wire and cable, optical cable, overhead wire, steel core aluminum strand, conveyor belt, safety belt, anchor chain, steel wire rope, cable and other soft samples. The machine adopts servo motor loading, decelerates through the deceleration system, drives the screw rotation, turns the rotation into a translational mechanical structure, the system adopts double screw, transmission, double screw configuration double nuts can effectively ensure the tensile load and transmission efficiency, the system adopts three-phase 220 power supply (built-in transformer). The oil-free system reduces energy consumption, low noise, and does not cause any noise and environmental pollution to the surrounding environment. The biggest feature is that the control precision is high, the acquisition speed is fast, and the control response is fast, which is unmatched by the electro-hydraulic servo system.

Microcomputer controlled electronic horizontal tensile testing machine is mainly suitable for testing steel wire rope and other products under rated test force or constant load tensile stress strain and breaking test.

Force measurement method: high precision load sensor imported from the United States

Control test mode: the computer automatically controls the test process, the computer screen displays the test force and test curve, and the test data is automatically processed according to the requirements of the test method.
