Dry burning electric heating tube benefits:
1, small diameter, can do 3-25mm.
2, the length is not limited, can do 20-2000mm.
3, high power, is 2-5 times the power of the normal dry burning electric heating tube, can do (surface area of 20 watts/square centimeter), even foreign can do (surface area of 60 watts/square centimeter).
4, with simple structure, high mechanical strength, high thermal efficiency, safe and reliable, simple installation, long service life, no pollution, cheap and other characteristics, at the same time save electricity, safe use, can be bent into a variety of shapes, light, convenient disassembly and assembly.
Dry burning electric heating tube structure:
The typical structure of dry burning electric heating tube (the most popular structure) is the same as that of dry burning electric heating tube. It is generally composed of five parts: insulator, sealing material, lead rod, filling material, electric heating wire, metal casing and wiring end. The spiral electric heating wire and lead out help are located in the central metal casing, its manufacturing process is to spiral electric heating wire into seamless steel tube, copper tube or aluminum tube, the gap through the multi-tube filling machine evenly filled both insulation and heat conduction of oxidation medium, such as crystalline magnesium oxide powder (also available alumina or clean quartz sand). Then use the tube shrinking machine to shrink the tube diameter, so that the oxide medium is dense (density of 3.3g/cm3 or more), to ensure that the heating wire is isolated from the air, the central position does not offset and touch the tube wall. Like this. Unit area calorific value can increase ten times. Service life can also be correspondingly increased to more than 10 years. Compared with the heating element with the same amount of heat, the tubular dry-fired heating tube can save 5% of the heating material, and the thermal efficiency can reach more than 90%.
Dry burning electric heating tube difference:
1, appearance: dry electric heating tube is one end (one end), ordinary dry electric heating tube is two ends of the line.
2, internal structure: the winding way of dry burning heating tube and ordinary dry burning heating tube is different, especially now the imitation of imported U-type electric head tube, and ordinary dry burning heating tube has a great difference.
3, production process: dry burning electric heating tube in the production process than ordinary dry burning electric heating tube has more technology, such as shrinkable tube, which ensures that the power of dry burning electric heating tube is higher than ordinary dry burning electric heating tube, and the service time is long
