Description:

Chair Legs Pressure-resistant Tester is used to test the Office Chair supports five claws,by vertical pressure to test compressive strength of five claws.

The motor which is used as power source is controlled by computer.Driving the Precision screw and dragging the bar to make pressure down.

Purpose of test:test compressive strength of the Office Chair claws.Control the quality of products.Find the position of defect.Provide a reference for improvement.

Program of test:Load to 11120N slowly,keep one minute.uninstall;Then load to 11120N slowly again,keep one minute,record the process of test.

Assessment of results:controlled by a servo motor which can maintain constant pressure when chair legs are in plastic deformation status.

The tester which is controlled by computer stops automatically when breakpoint occurs.Customers can write test program by themselves;The computer generates  force – time and force – shift curve automatically.

Main controller adopts most advanced 32 bit ARM processor in the 21st century.Processing speed has already reached the level of Pentium general computer.Compared with the traditional 8-bit SCM measure-control system, the performance of it is greatly improved.The speed of arithmetic  is more faster,The precision of control is higher.

The core device which is used for collecting data  adopts the latest ultra-high precision 24-bit AD.The rate of sampling can reach 2000 times per second.Can capture the process of the force variation at the moment.The whole journey don’t step.Resolution comes up to 500000 degrees,and uses the original 6 point calibration technology,improving the accuracy further.

The measurement accuracy of force is much higher than 0.5 (the highest) standards of the state.

Windows standard style.Distinct operating mode,detailed documentation and tips make it becomes the most simple and easy software to use in testing machine industry.

Your training efficiency of modulation and software will be improved significantly.

Using multi-threaded parallel processing technology.Testing process show force – shift, force – time, shift-time and stress-strain curve at the same time in time.Can switch to the picture of curve what you want to see, and can check the user setting etc.Cabinet protection structure, guarantee safety absolutely.The tester stops automatically when the five claws of chair damage.It can be set fixed pressure and time.
