Hydraulic universal testing machine is mainly used for tensile, compression, bending, shear and other mechanical property tests of metal, non-metal, composite materials and products. It is widely used for material inspection and analysis in aerospace, machinery manufacturing, wire and cable, rubber and plastic, building materials and other industries. It is widely used in scientific research institutes, colleges and universities, industrial and mining enterprises, technical supervision, technical supervision Ideal testing equipment for commodity inspection and arbitration departments. Let's talk about the test steps of hydraulic universal testing machine:

1. Connect the power cord, press the "power" button, and the indicator light will be on.

2. Select the measuring range according to the sample specification.

3. According to the test shape and size, put the corresponding jaw into the upper and lower jaw seat.

4. Start the oil pump, unscrew the oil supply valve to raise the bedplate by about 10mm, and then close the oil supply valve. Nanning vitiligo hospital if the platen has been in the raised position, it is not necessary to start the oil valve to send oil, just close the oil valve.

5. Clamp one end of the test into the upper jaw. For the machine equipped with hydraulic chuck, press the "tighten" button on the oil control box to clamp the sample.

6. Start the lifting motor to adjust the test space and clamp the sample vertically. For the model with hydraulic chuck, press the down button on the control box to clamp the test vertically.

7. According to the speed required by the test, slowly open the oil delivery valve to add force, close the oil delivery valve after the test is broken, and stop the oil pump if the interval of the next group is long.

8. Remove the test. For the machine equipped with hydraulic chuck, first press the "up" button to release the upper jaw, and then press the "down" button to release the lower jaw, and take down the test pieces.

9. After the test, disconnect the power cord.

Correct test operation sequence can not only ensure the accuracy of test data, but also extend the service life of hydraulic universal testing machine.
