Scheme for troubleshooting common faults of tensile testing machines

one,Tension testerWhen loading, the pointer trembles or moves and stops

1. Clutch gear wear: Need to be repaired or replaced.

2. Wear of the leather washer or spring of the friction plate: The leather washer or spring needs to be replaced.

3. Move the joystick: Adjust the joystick to fit well with the alveolar.

2. When changing the swing weight, the pointer does not return to zero.

1. The installation of the tensile tester is not level: Use a level to adjust the tester level.

2. The pendulum is not vertical: only hang the A-power. Adjust the balance weight to make it vertical.

3. The pendulum return to the tensile tester too fast or too slow

1. Improper position of the buffer valve gear: Adjust the buffer valve to the appropriate position.

2. Hydraulic oil viscosity is too low or too high: When the hydraulic oil viscosity is too low, the pendulum will fall back quickly, and when the viscosity is high, the hydraulic oil should be replaced with appropriate viscosity.

3. Dirt in the buffer valve, oil pipe or hydraulic oil: Clean the buffer valve, oil pipe. Replace hydraulic oil.http://www.hssdtest.com/
