This 30-ton microcomputer-controlled vertical conveyor belt longitudinal tensile testing machine is designed by our company based on the longitudinal tensile strength of the standard MT/T668-2008 Steel Wire Cord Flame-Retardant Conveyor Belt for Coal Mines and MT/T318.1-1997 Technical Conditions for Mechanical Joints of Conveyor Belts for Coal Mines.It can also be used to test mechanical properties such as tension, compression, bending, shearing, peeling, and tearing of various metals, non-metals, and composite materials.The system adopts microcomputer closed-loop control, has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity for the measurement and control of load and displacement.
The testing machine adopts a digital AC servo speed regulating system and a motor with high speed regulation accuracy and stable performance as the driving system; a specially designed synchronous toothed belt deceleration system and a ball screw pair drive the moving beam of the testing machine; the control and data processing software based on database technology using Windows as the operating platform adopts virtual instrument technology to realize test force, test force peak value, beam displacement, sampleThe screen display of deformation and test curves, all test operations can be completed by mouse input on the computer screen, with a good human-machine interface and easy operation; the comprehensive application of the above-mentioned technologies ensures that the machine can achieve closed-loop control of parameters such as test force, specimen deformation and beam displacement, and can realize tests such as constant force, constant displacement, constant strain, constant speed load cycle, constant speed deformation cycle, etc.
