What should I do before the test of the electronic tension testing machine?

Causes and methods for eliminating vibration of electronic tensile tester:

1. The installation foundation is not firm or the ground corner bolts are loose.

・Exclusion method: Reinforce the foundation and tighten the corner bolts.

2. If there are impurities (iron filings, sand grains, etc.) between the lifting screw and the nut, grind the screw and nut.

・Exclusion method: Take out the screw, repair the damaged part, and add lubricating oil with a high viscosity, such as cylinder oil after installation.

3. The bearing capacity of the brackets on both sides of the lower jaws is uneven. The friction is large and the friction is small. Wobble and vibration will occur when lifting and lowering.

・Exclusion method: You can remove the bracket and reinstall it and add a little lubricating oil.

Necessary inspection points for the control panel of the tensile tester

1. Panel display function.

2. Panel button function.

Tension testing machine often needs to be lubricated

1. Speed ​​reduction system under the workbench

2. The upper and lower end bearings of the lead screw

3. Lubrication of screws and wire master

The main power supply of the tensile tester is powered but the equipment cannot move up and down. The solution is to check whether the device cannot move after 15S (time), because the host needs to be self-checked, which takes about 15S time; check whether the upper and lower limits are in the right position and have a certain operating space; check whether the power supply voltage connected to the test machine is normal.
