Consequences of failure of buffer valve of universal testing machine

When checking the hydraulic universal testing machine, you often encounter itUniversal testing machineThe buffer valve failure.

When the universal testing machine performs compression test (such as concrete pressure test, steel bending resistance, etc.), if the buffer fails, its performance is not obvious.

When performing a fracture test (such as pressure resistance, steel pulling, etc.), the pendulum will fall down quickly, causing an impact on the pendulum dead center. If it fails for a long time, the consequences will be:

(1) The impact on the dead center for a long time will cause deformation;

(2) The bearings of the hydraulic universal testing machine are damaged;

(3) Push rod (mostly aluminum alloy) Ribbed sliding teeth and push rod is not available at zero point when deformation is severe.
