Ring stiffness testing machine/Electornic universal testing machine

WDW-H series microcomputer control ring stiffness testing machine adopts mechanical loading, electronic measurement, digital continuous speed regulation, and real-time control by computer. This machine carries on the digital display to the test force, the displacement / the speed simultaneously, and has the test force peak value retention function.Suitable for plastic pipe girth flexibility, ring stiffness, flat, weld tensile, pipe creep ratio. Industrial and mining enterprises, scientific research institutes, colleges and universities, commodity inspection arbitration, technical supervision and other departments of the ideal testing equipment.


Working principle:

The ring stiffness is determined by the measured force and deformation value of the pipe at constant speed deformation.The compression speed of the plate is determined according to the diameter of the pipe, and the pressure is applied to the specimen in the vertical direction of two parallel plates.A reaction force is generated during deformation, and the ring stiffness is calculated by using the force value of 0.03 di in the direction of the diameter of the tube specimen.
