Today I have summarized some simple measures for judging the quality of electric heating tubes. This is helpful for us to use and buy electric heating tubes in our daily life. Here we thank Mr. Sun for taking the time during such a busy time. Summary Some judgment methods for electric heating tubes.
First of all, we must first know the basic characteristics of some good electric heating tubes. There are two summary:
1. The electrical performance of the electric heating tube is operating normally
After the carbon fiber quartz electric heating tube is energized, the power is stable within a certain tolerance range during frequent startup, shutdown and long-term continuous operation, without any instant power shock.
2. High heat conversion rate is the most critical part of electric heating tube
High thermal efficiency, more than 30% energy saving than general metal heating element, extremely fast heating speed. Carbon fiber heating element is a pure black body material, so it has rapid heating, small thermal hysteresis, uniform heating, long heat radiation transfer distance, and fast heat exchange speed. Features. The luminous flux during the working process is much smaller than that of the electric heating tube of the metal heating element, and the electric heating conversion efficiency is as high as 95% or more (that is to say, if you use an ordinary electric heating tube of 1000w, it only needs 700w when using a carbon fiber electric heating tube).
How to judge the quality of the electric heating tube? In fact, the most intuitive way to verify the quality of the electric heating tube is: first wipe the surface of the electric heating tube, then switch on the AC 220V power supply, dry it in the air, and turn off the power after the surface turns red. After the electric 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), indicating that it is a high-quality electric heating tube. Otherwise, it is inferior.
