Pipeline electric heaters are widely used, such as in industrial fields and other places. However, due to other reasons, such as the complex design of the machine itself and the relatively narrow functional plate, the operation of the product and the user must learn the processing knowledge in advance according to the actual situation, so as to achieve the expected effect and ensure a relatively good advantage in the later practical use. So the information introduced today is about the knowledge of pipeline electric heater. First, the pipeline electric heater is introduced. The pipeline electric heater is composed of several tubular electric heating elements, cylinders and guide plates. The tubular electric heating element is characterized in that the high-temperature resistance wire is put into the metal tube, and the gap is tightly filled with crystalline magnesium oxide powder with good insulation and thermal conductivity, and the tubular electric heating element is used as the heating element, with advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance and wear resistance. A diversion baffle is installed in the cylinder, which can make the air heated evenly in the circulation process. The utility model relates to a pipeline electric heater, which belongs to an electric heating device for heating a pipeline or a medium in the pipeline. It consists of a temperature control unit composed of a single chip microcomputer and a temperature sensor, and also has two bearing-bush-shaped metal inner shells, and electric heating tubes are fixed on the inner wall surfaces of the two metal inner shells respectively; It also has two bushing-shaped molded heat-conducting layers made of heat-conducting materials and used for being sleeved on the pipeline, and the outer wall surfaces of the molded heat-conducting layers are attached to the inner wall surfaces of the two metal inner shells; It also has two bearing bush-shaped molding insulation layers attached to the outer wall surfaces of two metal inner shells, and the two bearing bush-shaped shells are arranged on the outer surfaces of the two molding insulation layers; There is also a fixing member for clamping the heating assembly on the pipeline. The invention has high thermal efficiency, convenient installation and disassembly, and is widely applicable to various pipeline heating occasions. Second, it can be used for heating, stirring and heat preservation of pipelines, tanks, towers and tanks of industrial equipment in 1 humid and explosive gas-free occasions, and can be directly wound on the surface of the heated part when in use. Second, it can be used for anti-freezing and auxiliary heating of air-conditioning compressors, motors, submersible pumps and other equipment. This product is mainly composed of alloy heating wire and silicone rubber high temperature insulating cloth. It has the advantages of rapid temperature rise, uniform temperature, high thermal efficiency and good toughness, and meets the fire resistance standard of UL94-V0 in the United States. Easy to use, safe, waterproof, aging life up to five years. The above is the application scope and introduction of pipeline electric heater, as well as the matters needing special attention when installing plates. It is not difficult to know that the operation and use of pipeline electric heaters are still relatively high for users. For practical friends, we must have corresponding rich knowledge and experience. Therefore, the above is analyzed from everyone's point of view and is worth learning and referring to.
