The electro-hydraulic servo universal testing machine is mainly used for the tensile, compression, bending, shearing and other tests of metal materials. It is equipped with corresponding fixtures for the tensile, compression, bending, shearing, bending and other tests of other types of samples. What are the precautions for the operation of the electro-hydraulic servo universal testing machine?

1. During the test, when the oil pump suddenly stops working, the oil return valve shall be opened immediately to remove the test force.

2. During the test, if the electrical appliance suddenly fails and the start or stop button does not work, the power supply shall be cut off immediately to stop the test machine.

3. The purpose of the moving beam and the adjustment of the test space. During the test, it is strictly forbidden to start the moving beam when applying force or removing force, otherwise the lifting drive mechanism may fail.

4. When installing the bending support, pay attention to the calculation of the distance between the supports. The scribed line on the support is the position of the idler center line. The wrong calculation may cause the connecting rod connecting the two supports to break.

5. For models equipped with hydraulic chucks (configured according to the user's needs), the power supply of the oil pump motor should be cut off before changing the jaw to avoid injury caused by the action of the hydraulic chucks due to misoperation.

6. It is prohibited for non operators of the machine to operate on the machine.

7. Do not start the oil pump or check the cause under high pressure.
