How to operate a hydraulic universal material testing machine? Operation steps of hydraulic universal material testing machine

Hydraulic universal testing machine refers to special equipment used for testing of tensile, compression, bending, shear, etc. of metal materials. The microcomputer screen display hydraulic universal test machine is a high-rigid main machine structure with a cylinder under-mounted high-rigidity main machine. The disc motor drives the turbocharger to move up and down along the screw to adjust the test space. The servo cylinder adopts gap sealing and static pressure support oil film frictionless guidance technology. Today, the editor will introduce the multi-faceted integration of the operating procedures of the hydraulic universal testing machine manufactured by Jinan Hengsi Shanda Instrument Co., Ltd.

1. Regarding the operation method of hydraulic universal testing machine: (From Baidu)

1. Dish selection: Before the test, the maximum load should be estimated and the corresponding measurement range should be selected so that the limit load during damage is controlled between 20 and 80% of the disc at this stage.

2. Measurement range: Hanging thallium

0~10KN A

0~20KN A+B

0~50KN A+B+C

3. According to the system used, the "Calibration" item is optional.

4. Open the file and follow the file instructions.

5. Pre-enter the sample size before the test.

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

7. Save: Manually save the test data, launch the system to conduct new tests, and automatically save the test data when opening the test data.

8. After the test is over, check whether 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 records of the equipment use.

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

1. Connect the power cord and press the "Power" button. The indicator light is on.

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

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

4. Roll the recording paper on the drum of the depictor (this item is only done when needed).

5. Turn on the oil pump to unscrew the valve of the oil supply supplier Hebei Dahong Experimental Instrument Co., Ltd. so that the test bench is about 10mm, and then close the oil supply valve. If the test bench is already in the raised position, there is no need to start the oil pump first, just close the oil supply valve.

6. Clip one end of the sample into the upper jaw (if the sample is heavier, you need to adjust the balance weight).

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

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

9. Put down the pen of the push rod and enter the drawing state (it is done only when needed and match the drawing ratio).

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

11. After the sample breaks, close the oil supply valve and stop the oil pump from working.

12. Lift up the depiction pen that records the value.

During use, correctly using the hydraulic universal testing machine and correctly maintaining the hydraulic universal testing machine can greatly improve the service life of the hydraulic universal testing machine and give full play to the value of the hydraulic universal testing machine. At the same time, it can also bring good help and greater convenience to our work and improve our testing performance.
