How to use a universal test machine

Universal testing machine, a veritable material testing machine integrating tensile, bending, compression, shear, ring stiffness and other functions. It is mainly used for mechanical properties tests of metal and non-metallic materials. It is an ideal testing equipment for industrial and mining enterprises, scientific research institutions, colleges and universities, engineering quality supervision stations and other departments. So how to use such a universal testing machine? Let’s learn with the editor:

1. Turn the main switch on the power supply.

2. According to the sample, select the measurement range, hang or remove the swing thallium on the swing rod and adjust the buffer valve handle to align the standard line.

3. Install the corresponding chuck into the upper and lower jaw seats according to the shape and size of the sample.

4. On the drum of the depictor, roll the recording paper (grammed paper). This item is only carried out when necessary.

5. Turn on the oil pump motor, unscrew the oil feed valve to make the test stand raise paper 10 mm, and then close the oil valve. If the test stand is already in the raised position, there is no need to turn on the oil pump first, just close the oil feed valve.

6. Clip one end of the sample into the upper jaw.

7. Turn on the oil pump adjustment point to the zero point of the accuracy dial.

8. Turn on the lower jaw motor, lift and lower the lower jaw to an appropriate height, clamp the other end of the sample into the lower jaw, and be careful to make the sample perpendicular.

9. Put down the drawing pen on the push rod and enter the drawing ready state (it is only done when it is required).

10. According to the loading speed required by the test, slowly unscrew the oil feeding valve for loading test.

11. After the sample is broken, close the oil valve and stop the oil pump motor.

12. Record the required values ​​and will be depicted.

13. Open the oil return valve and turn the passive needle back to zero after unloading.

14. Remove the broken sample.

15. The above tests can be carried out in accordance with the above items.

To sum up, it is the use of the universal testing machine compiled by the editor for you. I hope it can help you.
