Ten inspections of tensile testing machine before use
Tensile testing machine is a mechanical test machine used to test the mechanical properties of materials. Different materials require different fixtures. It is also an important factor in whether the test can be carried out smoothly and the accuracy of the test results. It is suitable for testing various physical and mechanical properties of plastic plates, pipes, profiles, plastic films, rubber, wires and cables and other materials for material development.
1. The main points of inspection before use of electronic tensile testing machine
1. In an environment with low room temperature and relative humidity.
2. The tensile testing machine is installed correctly.
3. There is no corrosive medium around.
4. The power supply voltage fluctuates little
5. The host must be grounded.
Second, the electronic tensile testing machine beam operation inspection
1. The beam is operating normally
2. Smooth operation at various speeds
3. Running distance, whether it is overshoot.
4. Belt and tension.
3. Necessary check points on the control panel of the electronic tensile testing machine
1. Panel display function.
2. Panel button function.
Fourth, the tensile testing machine often needs to be lubricated
1. Reducer under the workbench
2. Bearings at the upper and lower ends of the screw
3. Lead screw and nut
5. Space inspection of electronic tensile testing machine
1. Stretching and compressing limited space
2. Effective distance of testing machine
3. Machine size
4. Testing machine workbench
6. The load system of the electronic tensile testing machine must be checked
1. Is the sensor's appearance damaged?
Seven, check the response system
1. Calibration and zero reset of extensometer: measure the standard length.
8. Inspection of the transmission system of the electronic tensile testing machine
1. Motor noise
9. Inspection of accessories, such as fixtures, instruction manuals, software user manuals, certificates, packing lists, accompanying tools, etc.
10. Safety performance inspection of electronic tensile testing machine
1. Overload protection function
2. The machine will stop automatically when the sample is broken
Remarks: The basic functions of the tensile testing machine: tensile performance, tensile strength and deformation rate, tensile strength, tear resistance, heat seal strength performance, roller peel test, 90° peel, 180° peel, rope break Different tests such as force, trouser tearing force, compression test, bending test, shear test, burst test, etc., can be installed with different clamps, wide specimen clamps, Japanese-style clamps, and British-style clamps according to the different needs of customers. It meets the standards of many countries.
