Key points to note when purchasing a relaxation testing machine

Relaxation testing machine,mainly used fortesting the relaxation performance ofmaterials.. Nowadays, the main body of the horizontal pull structure is much better than the earliest vertical structure. There are two main light bars on each side, which are arranged in a trapezoidal pattern. Its advantages are obvious, and its operation is simple and convenient. The key is that it has a large stretching space and can accommodate long specimens.

So what are the aspects we need to pay attention to when choosing a relaxation testing machine?

Firstly, whether its structural framework is reasonable, as the relaxation testing machine needs to be subjected to load testing for a relatively long period of time, with an average testing time of100hours. During such a long period of time, the equipment is in a state of stress load. If the structural framework is not firm and the strength that the equipment can withstand cannot reach, it will cause the relaxation testing machine to experience relaxation, resulting in inaccurate experimental results. Therefore, the main body frame of the relaxation testing machine should be able to withstand sufficient strength and have a compact structure.

       

Secondly, the performance of the force measurement system is stable, as it includes force sensors whose performance directly affects the device's ability to resist relaxation. Therefore, it is necessary to choose load sensors with high stability and accuracy to significantly reduce the relative error of test results.

Thirdly, evaluate the control system and transmission system. Both of these systems belong to servo motors. The quality of servo motors directly affects the transmission efficiency and smoothness during the entire testing period, as well as the level of noise generated. Therefore, choosing high-quality and stable servo motors can greatly assist in the normal operation of the relaxation testing machine.

Fourth, the accuracy and stability of the deformation sensor. Because during the operation of the relaxation testing machine, it is necessary to maintain consistent deformation of the material in order to measure the attenuation of its stress over time. The role of deformation sensors here can be said to be crucial.

Finally, fixtures with strong performance are convenient for experimental operations. Like a three piece wedge-shaped fixture, it is much more firmly clamped.

After the introduction above, I believe everyone will popularize knowledge and choose the best when purchasing a relaxation testing machine. If you have further questions, please feel free to call Jinan Liling Testing Machine Co., Ltd. for more information.
