Operation and Use of Universal Testing Machine


There are two types of universal testing machines: electronic universal testing machines and hydraulic universal testing machines. The power source of electronic universal testing machines is the motor, and the general testing force value is within 200KN. The power source of hydraulic universal testing machines is the oil source, and the testing force value is between 300KN-2000KN. Customers can choose equipment based on the force value of the production product. The main functions of universal testing machines are tension, compression, bending, shear Today, we will introduce the operation and use of the electronic universal testing machine for mechanical performance testing such as peeling.

The testing force values of the electronic universal testing machine include 10KN, 20KN, 50KN, 100KN, and 200KN. Customers can choose the force value according to their own requirements, and it is important to remember that the testing range of equipment at level 1 is within 2% -100% and should not exceed this range.

1: Environmental requirements: no vibration or dust; Room temperature 10 ℃~35 ℃; Humidity ≤ 80%; There is no vibration, corrosive medium, or strong magnetic field interference around;

2: Power supply: single-phase 220V ± 10%, 50Hz

3: The power supply of the testing machine should be reliably grounded; The fluctuation of frequency should not exceed 2% of the rated frequency;

4: After confirming that the power and signal connections of the device are correct, the power can be turned on in the following order:

5: Power on: testing machine → computer → printer

Note: The startup sequence of the host and computer can affect the communication initialization settings of the computer, so it is important for users to strictly follow the above startup sequence.

Attention: After each startup, it is necessary to preheat for 5 minutes and wait for the system to stabilize before proceeding with the test work.

Special note: If the computer has just been turned off and needs to be restarted, ensure a minimum interval of 1 minute. After completing the test work, the machine can be shut down in the following order:

6: Prepare the test sample, and the size of the test sample should refer to industry standards or national standards for operation.

7: Use a manual remote control to adjust the position of the crossbeam for easy clamping of the sample.

8: Add sample size in the software.

9: Select the desired testing items in the software, such as tension, compression, deformation, elongation, elastic modulus, etc

10: When selecting the testing speed, the testing speed for metallic materials is 50mm and for non-metallic materials is 100mm

The above can meet the testing requirements, and now we can proceed with testing
