Everyone knows that the universal tensile testing machine is a category of mechanics, so the classification basis of the testing machine is the force. The unit here is Newton (N), but because of the fact that Newton expressed a bit in the actual application process. Small, so it is now common to use KN to make units.
For example, the universal tensile testing machine for electronic materials is generally classified into WDW (WDS)-0.01 (that is, 0.01KN), 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, etc. That is 1, 2, 5 to do the interval. The test force is generally very small, and the jargon is simply called "electric pull".
The hydraulic universal tensile testing machine is relatively large, but the category is relatively simple, WEW (WE)-100KN, 300KN, 600KN. 1000KN and other categories, of course, other categories are also not included in the regular equipment. So simply speaking, the hydraulic universal testing machine is separated by 1, 3, and 6.
The most obvious difference between the hydraulic universal tensile testing machine and the electronic material universal tensile testing machine is the power source. It is also well understood that the electronic material testing machine is powered by 220V or 380V. The hydraulic universal testing machine uses special hydraulic oil to do kinetic energy.
The above is the classification of some common universal tensile testing machines. Calculate your testing machine according to the maximum test strength you use. By comparing these models, you can easily select the most suitable testing machine. Such experimental data will be more accurate. I hope that it will be helpful to friends who want to buy a universal tensile testing machine.
