Introduction to the measurement system and control system of stainless steel pipe elongation test machine

The stainless steel pipe elongation test machine adopts microcomputer control and combines advanced electronic control technology to implement standardized and unit-based design. It has the characteristics of accurate control, high measurement accuracy, flexible configuration, and easy accessory exchange and easy after-sales service. Below I will share with you the introduction of the measurement system and control system of the stainless steel pipe elongation test machine.

1. Measurement system of stainless steel pipe elongation test machine:

Load measurement: Use FS0.2% imported high stability and high precision load sensors.

Sample deformation measurement: There are three ways: through displacement or large deformation or small deformation measurement and control panel, a 20-bit A/D conversion single-chip acquisition system is used, and the microcomputer acquisition system can realize the deformation measurement of the sample.

Displacement measurement: The coaxial angle of the Japanese high-precision photoelectric encoder and the lead screw are used to measure the cross beam (i.e., the absolute displacement of the upper and lower chucks) through a digital circuit.

2. Stainless steel pipe elongation tester transmission control system: D/A conversion and microcontroller and computer control system Schneider fully digital AC servo motor is connected to the reducer, and the high-precision ball screw is driven to rotate and load through synchronous gear belt. The transmission efficiency is high, the noise is low, the transmission is stable, and the speed accuracy is guaranteed to be ±0.5% of the displayed value.

3. Data processing software package

The control system software adopts a WindowsXP/Me/2000 operating system platform, which has fast running speed, friendly interface, simple operation, and can meet the needs of test methods for different materials. Meets the requirements of compression, stretching, bending, shear, top breaking, fatigue, etc. If there are special requirements, the software can be customized. And the software can be expanded according to user requirements. It can meet the requirements of GB, ASTM, DIN, JIS and other standards. This software package has the following main features: the kernel is centered on the Access database and combined with the SQL language to facilitate data acquisition. New test treatment methods can be easily added. Main functions:

(1) Synchronous measurement and display of force values, large deformations, small deformations, and displacements.

(2) Set the test speed arbitrarily. (From 0.001-500mm/min, stepless speed regulation)

(3) The test curve is displayed in real time, and the horizontal and vertical coordinates are automatically shifted.

(4) You can set automatic judgment or not and automatic return to the starting point or not. You can set a fixed time stop, a fixed load stop, a fixed deformation stop, and a fracture judgment condition can be set.

The above is an introduction to the measurement system and control system of the stainless steel pipe elongation tester. I hope the above brief introduction can help you.
