Rubber sealing belt clamping performance testing machine

WDL-5 microcomputer controlRubber sealing belt clamping performance testing machineIt is a microcomputer-controlled electronic tensile testing machine specially designed by Shandong Huayan Testing Machine for rubber sealing strips in telescopic devices of highway bridges.The computer system controls the rotation of the high-precision stepper motor through the full digital controller and the speed control system. After deceleration by the deceleration system, the moving beam is driven by the precision ball screw pair to complete the repeated tensile mechanical property test of the sample. It is suitable for performance testing of rubber sealing tapes in highway bridges and other applications.The equipment complies with the specification requirements of JT/T327-2016 "General Technical Conditions for Telescopic Devices of Highway Bridges".
