50KN Computer Servo Plastic Tube Ring Stiffness Test Equipment



The ring stiffness test equipment is widely used in thermoplastic plastic tubing with circular cross section, and the stiffness for grass steel tube. The tester can meet the standard requirement of PE arms bellows,winding pipe, and all kinds of tubular product standards, at the same time, can do the tubular product ring stiffness,ring flexibility,flat,tensile test.With the function of key adjust, digital display for test force displacement, value keeping, broken automatically stop, overflow, overload automatical protection.


Testing principle:

Ring The principle of stiffness test equipment is, the testing value and deformation value of tubular under the constant deformation. Normally, can be used in Water seepage drainage pipe,discharge pipe, Irrigation pipe, pipe, mud, communication protection tube.


The main function:

It is suitable for testing metal and nonmetal material, such as rubber,plastic, wire cable, optical fibre and cable, safety belt,leather belt composite, plastic material, waterproof roll,steel tube,proximate material,spring steel,ball bearing steel, stainless steel( and other high-duty steel),casting,steel plate,steel belt,tensile,compression,bending,cut, stripping,tear,two points extension( need additional extensometer.


Main features:

1. The machine apply double space structure with four columns frame: Pull up and press.

2. Speed adjusting system apply servo speed adjustment system and servo motor, stable and reliable performance, with the mechanical protection device for overcurrent,overpressure and overload.

3. The drive part apply arc synchronization cog belt, vice transmission by precision ball screw, smooth transmission, low noise, high transmission efficiency.

4. Cardan joint apply cross bolt structure, with the function of pendulum angle limit,not only can fix the sample, guarantee the concentric degree of test, also can eliminate the influence for the sensor from irregular sample.

5. Equipped with specialize ring stiffness deformation measuring device, which can help the deformation result more precision.

6. There are three models, which can suitable for tube with φ1000mm,φ2000mm,φ3000mm
