Operation steps of hydraulic universal testing machine, how to use hydraulic universal 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.

Hydraulic universal testing machine is a hydraulic material testing machine that can perform various tests such as tensile, compression, and bending. Hydraulic universal testing machine is used for tensile, compression, bending and shear tests of various metals and non-metallic materials, as well as special tests of some products. The test operation and data processing comply with the requirements of GB228-2010 "Metal Tensile Test Methods for Room Temperature Materials" and other standards.

About the operation method of hydraulic universal testing machine:

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.

13. After opening the oil return valve to unload, turn the driven pointer back to zero.

14. Remove the broken sample.

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.
