Introduction
The test machine uses the integrated structure of the motor and the speed control system to drive the synchronous belt deceleration mechanism, and drives the lead screw pair to load after deceleration. The electrical part consists of a load measuring system and a deformation measuring system. All control parameters and measurement results can be real time displayed on the LCD screen. And it has overload protection, displacement measurement and other functions. It can used for a variety of textiles and automotive interior materials tensile strength, tensile break elongation (or elongation rate) test. It can also be used for zipper, leather strength test.
Application
It can used for a variety of textiles and automotive interior materials tensile strength, tensile break elongation (or elongation rate) test. It can also be used for zipper, leather strength test.
Standards
GB/T 3917.2 Textiles-Tear properties of fabrics-Part 2 Determination of tear force of pants shaped test specimens (single slit)
GB/T 3917.3 Textiles-Tear properties of fabrics-Part 3 Determination of tear force of trapezoid-shaped test specimens
GB/T3923.1 Textiles-Tensile properties of fabrics-Part 1 Determination of breaking force and elongation at breaking force- Strip method
Calibration
Being ready for four rank standard special gravity weight or 0.3 level standard dynamometer.
Adjusting into the test control process and result analysis interface, exert force to the sensor, observe the force value display on screen and readings from the dynamometer are the same or not, if the deviation is comparatively large, presskey, while the status display shows "standard", as shown on the right.
In the calibration state, you can use key to adjust the force value (coarse adjustment, the range of adjustment is comparatively larger), can also use key to adjust the force value (fine-tuning, the range of adjustment is comparatively smaller), to make force value and real force value (ie dynamometer) match, and finally press the "confirm" button .
