Hydraulic universal testing machine refers to a specialized equipment used for tensile, compressive, bending, shear and other tests of metal materials. The microcomputer screen display hydraulic universal testing machine is a high stiffness main engine structure with an oil cylinder placed under it. The disc motor drives the turbine to move the screw nut up and down along the lead screw, adjusting the testing space. The servo oil cylinder adopts gap sealing and static pressure support oil film frictionless guidance technology. Today, the editor will introduce the integration of various aspects of the operating procedures of the hydraulic universal testing machine manufactured by Jinan Hengshi Shanda Instrument Co., Ltd.

1、 Regarding the operation method of hydraulic universal testing machine: (from Baidu Zhidao)

1. Selection of dial: Before the test, the maximum load should be estimated, and the corresponding measurement range should be selected to control the ultimate load at the time of failure between 20% and 80% of the level of dial.

2. Measurement range hanging thallium

0~10KN A

0~20KN A+B

0~50KN A+B+C

3. Depending on the system used, the "calibration" option is optional.

4. Open the file and follow the instructions in the file.

5. Pre input the sample size before the experiment.

6. New experiment: Save the current experiment results and start a new experiment.

7. Save: Manually save the data of this experiment, launch the system for a new experiment, and automatically save the data when opening the experiment.

8. After the experiment is completed, check if the machine is running normally. First, exit the program, turn off the computer, and finally turn off the power supply of the industrial control box. And keep a record of equipment usage.

2、 Regarding the operation method of hydraulic universal testing machine: (provided by Suzhou Kezhun Technology Department)

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

2. According to the sample, select the measurement range, hang or remove the weight on the swing rod, and adjust the switch handle of the buffer valve to the appropriate position.

3. According to the shape and size of the sample, insert the corresponding jaws into the upper and lower jaw seats.

4. Roll up the recording paper on the drum of the renderer (this only needs to be done when needed).

5. Start the oil pump and unscrew the valve of the oil delivery supplier Hebei Dahong Experimental Instrument Co., Ltd. to raise the test bench by about 10mm, then close the oil delivery valve. If the test bench is already in the raised position

When setting, there is no need to start the oil pump to deliver oil first, just close the oil delivery valve.

6. Clamp one end of the sample into the upper jaw (adjust the balance weight if the sample is heavy).

7. Start the oil pump and adjust the pointer to align with the zero point of the dial.

8. Start the motor, lift the lower jaw to the appropriate height, and clamp the other end of the sample in the lower jaw (be careful to make the sample vertical).

9. Put down the drawing pen of the push rod and enter the drawing state (only when necessary and adjust the drawing ratio).

10. Slowly open the oil delivery valve according to the required loading speed for the loading test.

11. After the sample fractures, close the oil delivery valve and stop the oil pump from working.

12. Lift the pen that records the numerical values.
