Hydraulic universal testing machine

Hydraulic universal testing machine

Function introduction:

The microcomputer screen display hydraulic universal testing machine is a high-rigidity mainframe structure under the cylinder. The disc motor drives the turbine to drive the wire to move up and down along the screw, adjust the test space, the servo cylinder adopts gap sealing, and the static pressure support oil film has no friction guiding. technology. Test machine dedicated plug-in full digital display test machine control system, manual loading test force, microcomputer screen display processing test results, automatic analysis and processing test data. Metallic material for stretching, compression, bending, shear test. The on-screen display measurement and control system has a network interface.

Operating procedure

a) Dial selection: The maximum load should be estimated before the test, and the corresponding measurement range should be selected so that the ultimate load at the time of failure is controlled between 20 and 80% of the grade disc.

(2) According to the system used, the “calibration” item is optional.

(3) Open the file and follow the instructions of the file.

(4) Enter the sample size before the test.

(5) New test: save the current test results and start a new test.

(6) Preservation: Manually save the test data, launch the system for new test, and automatically save the test data when the test data is opened.

(7) At the end of the test, check whether the machine is running normally. Exit the program first, turn off the computer, and finally turn off the power of the industrial control box. And make a record of equipment usage.

Operational precautions

(1) The connection line between the computer and the host must be checked before starting the machine.

(2) When using a computer, please do not read or write floppy disks that are not related to this machine in the future to prevent computer virus infection.

(3) Do not leave the position after the machine is running.
