1. Introduction to single-head electric heating tube with nut:
Single-head electric heating tube is also called single-ended electric heating tube and cartridge electric heating tube (r). It is a kind of electric heating tube (tubular electric heating element) in China. The industry has a model with a long-standing title:. In the late 1990s, due to the widespread use of electric heating pipes in China, many electric heating pipes for molds with one end out of the wire were called single-head electric heating pipes or single-ended electric heating pipes in southern China. In foreign countries, it is called a cartridge heater, which is also a vivid name because the cartridge shell is cylindrical and one end is blocked. In China, it is called a single-head electric heating tube, which is a coincidence.
2. Structure of single-head electric heating tube with nut:
The typical structure of single-head electric heating tube (the most popular structure) is the same as that of electric heating tube. It generally consists of several parts: insulator, sealing material, lead rod, Filling material, heating wire, metal sheath tube, terminals. The spiral heating wire and the lead-out are located in the center of the metal sheath tube. Its manufacturing process is to penetrate the spiral heating wire into the seamless steel pipe, copper pipe or aluminum pipe and fill the gaps evenly with a multi-tube filling machine that is both insulating and thermally conductive. Oxidizing medium such as crystalline magnesia powder (alumina or clean quartz sand can also be used). Then use a pipe shrinking machine to reduce the diameter of the pipe to make the oxide medium dense (density reaches ./above) to ensure that the center position of the electric heating wire and air isolation does not shift and hit the pipe wall. so. The amount of heat generated per unit area can be increased more than ten times. The service life can also be correspondingly increased to more than 10 years. Compared with electric heating elements with the same large amount of heat, tubular electric heating tubes can save 50% of electric heating materials and the thermal efficiency can reach more than 10%.
3. The difference between single-head electric heating pipes with nuts and other electric heating pipes:
Appearance: Single-head electric heating pipes have wires coming out of one end (one end), while ordinary electric heating pipes have wires coming out of both ends.
. Internal structure: The winding method of single-head electric heating tubes is different from that of ordinary electric heating tubes. Especially the current imitation imported single-head electric heating tubes are very different from ordinary electric heating tubes.
. Manufacturing process: The production process of single-head electric heating tubes has more processes than ordinary electric heating tubes, such as tube shrinkage, which ensures that single-head electric heating tubes have higher power and longer use time than ordinary electric heating tubes.
4. Advantages of single-head electric heating tube with nut:
, small diameter can achieve -.
, the length is not limited and can be -.
, high power can achieve (surface area watts / square centimeter) foreign countries can even achieve (surface area watts / square centimeter).
