In the process of purchasing electric heating tubes, we need to perform simple calculations on the purchased electric heating tube equipment before and during the purchase to obtain simple power, arc length, load and other factors, so that we can better purchase Can also get an advantage in inquiry. Now share the three commonly used calculation formulas with your family, and understand them together:
1. Power calculation formula: P=V2/R
(P stands for power, V stands for voltage, R stands for resistance)
2. Arc length calculation formula: L=nπR/180°
(L stands for length, n stands for angle, π stands for 3.14, R stands for radius)
3. Surface load calculation formula: W=Φ (diameter) x 3.14 (π) x L (actual heating length) x W (standard surface load)
We believe that when choosing a suitable electric heating tube, we must first understand the power of the electric heating tube to see if it can meet the heating demand. In addition, the quality of the heating tube can also be distinguished by simple experiments: the most intuitive way to verify the quality of the heating tube is: first wipe the surface of the heating tube, and then switch on the AC 220V power supply, dry it in the air, and the surface becomes red. After the power is turned off, after the heating tube is completely cooled, wipe it with a napkin. There should be no black oxidized powder on the white paper (not reacting with oxygen in the air), which proves that the heating tube is of high quality.
Of course, you can also introduce more knowledge points about electric heating tubes in this section, such as "Analysis of several reasons why electric heating tubes do not heat up", "Electric heating tube heating has unique advantages and higher benefits", and "Discussion on electric heating tubes. How to maintain the service life” and other related content, so that you can not only fully understand the various elements and principles of the electric heating tube, but also make it easier to use and maintain in the later stage. If you encounter problems in the use of the electric heating tube, you can directly consult our company and the technical staff experience More abundant; if there is a customer need to purchase, they can contact directly
