The glow wire testing machine is a kind of equipment used to test the combustion performance and heat resistance of materials, and is often used in building materials, automobiles, electronics, textiles and other industries. The following is a brief introduction to the operation process of the glow wire testing machine:
1. Preparation: Place the glow wire testing machine in a stable and ventilated place, turn on the power and preheat it. Select the appropriate glow wire diameter and material according to the test requirements, and install the glow wire into the holding device of the testing machine.
2. Sample preparation: cut the sample to be tested into a standard size, and place it on the test bench of the testing machine, adjust the position and height of the sample to align with the position of the glow wire.
3. Test: Start the testing machine, make the glow wire touch the surface of the sample, and record the ignition time, burning time, burning length and other data. According to the test requirements, multiple tests can be carried out, and the data of each test can be recorded.
4. Data processing: According to the test results, calculate the ignition time, burning time, burning length and other parameters of the sample, and perform data analysis and comparison. According to the test requirements, the data can be statistically and graphically displayed.
5. Cleaning and maintenance: After the test, turn off the testing machine and clean the test bench, glow wire, clamping device and other components of the testing machine. Regularly check the power supply, wires, glow wire and other components of the testing machine to ensure the normal operation, safety and reliability of the equipment.
The above is the basic operation process of the glow wire testing machine. The specific operation and precautions should be operated according to the model and instruction manual of the testing machine.
