How to choose a horizontal tensile testing machine and the matters needing attention in the experiment

The horizontal tensile testing machine adopts mature testing machine technology, adds a steel frame structure, and turns the vertical test into a horizontal test, which increases the tensile space. It satisfies the test of large sample and full-size sample. The space of the horizontal tensile testing machine is beyond the reach of the vertical tensile testing machine. This testing machine is mainly used for static tensile performance testing of materials and parts. It can be used for stretching various metal materials, steel cables, chains, lifting belts, etc., widely used metal products, building structures, ships, military industries and other fields. Next, let's learn more about how to choose a horizontal tensile testing machine and what are the precautions for the equipment experiment!





1. How to choose a horizontal tensile testing machine


1. First consider the maximum test tension range of the test material. You can refer to the national standards, and there will be requirements for testing power in the standards. Or provide the model size, let the testing machine manufacturer help to calculate, do not blindly estimate, or subject to the testing machine model.


2. The problem of test stroke


3. How about the basic configuration


4. Whether the output result is digital display or screen display


5. Types of experimental items that can be done


6. The accuracy of measurement and the accuracy of fully automatic are generally higher than those of ordinary digital display testing machines





Two. Matters needing attention in the experiment of horizontal tensile testing machine


1. Do not click the 'Start' test button before starting the test.


2. Every time you enter the program, if there is an abnormal prompt or the default load value is different from the previous one, do not perform the test, refer to the troubleshooting method for troubleshooting. The load value of the measurement and control system every time it enters the test interface should be near the zero point (no zero adjustment).


3. The horizontal tensile testing machine uses the cylinder reset button to raise or lower the cylinder piston to the set position. When the displacement display position value is greater than the set position, the piston will drop when you click the cylinder reset button; vice versa, The piston will rise. Pay attention to whether the actual position of the piston is consistent with the displayed position of the displacement. Do not use this key to raise or lower blindly when the cylinder is actually in the high position.


4. Do not 'zero' the load value after clamping the sample.


5. When clamping the extensometer, pay attention to the zero adjustment after unplugging the positioning pin; when removing the extension timing, pay attention to inserting the positioning pin to prevent the extensometer from being damaged due to artificial overload.


6. After the sample of the horizontal tensile testing machine is broken, if the program does not exit the test state and prompts the end of the test, you must immediately click the stop button to exit the test state.


7. After completing the test and exit the program, you should turn off the power with WINDOWS before cutting off the power; turn off the oil pump and let the oil cylinder fall to the end.


8. Be careful not to loosen the plug when moving the computer.
