7-step maintenance of common tensile testing machines

With the development of high-tech such as microcomputers, electronicsTension testerIt has been widely used in the industry, and every user can be said to pay great attention to the use of the test machine. The following are some suggestions on how to maintain the tensile test machine.

1. Before testing the test machine, the system must be preheated for more than 20 minutes, so that the temperature drift has little impact.

2. Before starting the test machine, check whether lubricating oil should be added to the frictional moving parts.

3. The oil used for the buffer should be kept clean. If the oil level is less than two-thirds of the depth of the cylinder, it should be replaced immediately.

4. Before adding the test piece, the brake handle must be stuck, and then release it after adding the test piece.

5. Refueling is not allowed on the main bearing of the dynamometer. The surface of the friction wheel in the gearbox must not be refueled or oil stains splashed. The friction surface should be clean and the inclined block on the swing arm must not be violently impacted.

6. After the test is completed, after the power is cut off, the test machine will be cleaned and protected in time.
