1. Structure of high-power stainless steel single-ended electric heating tubes
The typical structure (the most popular structure) of high-power stainless steel single-ended electric heating tubes produced by Yancheng Zhaishi Electric Heating and Electrical Factory is the same as that of electric heating tubes, and is generally made of It consists of: insulator, sealing material, lead rod, filler, heating wire, metal sheath tube, and terminal. 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 the gaps are evenly filled with a multi-tube filling machine, which is both insulating and Thermal conductive oxidation medium, such as crystalline magnesium oxide powder (alumina or clean quartz sand can also be used). Then use a tube shrinking machine to reduce the diameter of the tube to make the oxide medium dense (density reaches ./above) to ensure that the heating wire is isolated from the air and that the center position does not shift and hit the tube 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 % of electric heating materials, and the thermal efficiency can reach more than %
2. The difference between high-power stainless steel single-ended electric heating tubes and other electric heating tubes:
, Appearance: Single-ended electric heating tubes have wires coming out of one end (one end), while ordinary electric heating tubes 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 single-head electric heating tubes that are now imitated and imported are very different from ordinary electric heating tubes.
. Manufacturing process: The production process of single-head electric heating tubes requires more processes than ordinary electric heating tubes, such as tube shrinkage. This ensures that single-head electric heating tubes have higher power and longer use time than ordinary electric heating tubes.
3. Uses of high-power stainless steel single-ended electric heating tubes:
Single-ended outlet electric heating tubes are suitable for working in heating media where both ends cannot be connected, such as high and low temperatures in various large and small molds and mechanical equipment. Insertion heating, including dies and other moulds, medical equipment, plastic sealing machines, bottle capping machines, continuous automatic sealing machines, cigarette making machines, etc. The main ones are as follows:
. Used to dry wood, paper, printing and dyeing, paint residue, etc.
. Melting and heating of saltpeter and other salt substances.
. Melting low melting point alloys, such as lead melting furnace, tin melting furnace, etc.
. Building heating.
. Infrared radiation heating device.
. Low-temperature electric furnaces such as air circulation industrial electric furnaces, electric furnace boxes, etc.
. Heating device in oil, water and other chemical liquids and electroplating baths.
. Seawater electrodistillation device.
. Heating device for alkali and acid.
. In the food industry, it is used to bake various breads, biscuits, pastries, and as electric heating devices in water tunnels.
. In plastic product processing and molding extrusion equipment and rubber product molding and vulcanization equipment.
. In medical and sanitary disinfection equipment, such as sterilizers, sterilizers, etc.
. Heating of motor vacuum impregnation equipment, enameled wire drying device, etc.
. Various household electric heating appliances in daily life, such as electric stoves, electric ovens, rice cookers, electric woks, electric frying pans, water heaters, electric irons and other products.
