1, mold heating: (single head) or (cartridge) electric heating element (Cartridge Heaters), in the Chinese electric heating industry, there is a long-term model: M3. In the late 1990s, due to the wide application of electric heating element in China, the shape of electric heating pipes is also very large. In southern China, the electric heating pipes for such a outgoing mold are called single-head electric heating pipes, which are very similar. It is also called the cartridge heater in foreign countries. It is also called the image. Because the cartridge shell is cylindrical and one end is blocked, it is a coincidence with China that it is called a single-head electric heating tube.
2, liquid heating: U-shaped electric heating element (U) Modality Screw Plug Immersion Heaters, Screw Plug Immersion Heaters, Flange Immersion Heaters. Some types of electric heating tubes are filled with water, oil, thick liquid, alkali solution, acid solution or the like or in a pressure tank.
As an electric heating element, the Cartridge Rod Heater mainly converts electric energy into heat energy, and can be used alone or in various electric heating apparatuses. However, it is reflected that the electric heating tube will leak when it is used alone, and it will take a long time to break. Here you need to remind the users, if there are these two types of problems, then the products you buy are likely to be unqualified.
1. When the Cartridge Rod Heater is used to heat the easily melted metal or solid nitrate, paraffin, asphalt and other materials, the heating material should be melted first. At this time, the external voltage of the Cartridge Rod Heater can be reduced, and then the rated voltage is restored after the melting is completed. In addition, when the electric heating pipe heats a substance that is prone to explosion accidents such as nitrate, it is necessary to fully consider safety measures.
2. When the Cartridge Rod Heater is used for air heating, pay attention to the uniform arrangement of the Cartridge Rod Heater. The advantage of this is to ensure that the Cartridge Rod Heater has a relatively sufficient and uniform heat dissipation space, and as much as possible to ensure the fluidity of the air and improve the heating of the Cartridge Rod Heater. effectiveness.
3. The gap inside the Cartridge Rod Heater is filled with magnesia oxide. The magnesia sand at the outlet end of the Cartridge Rod Heater is easily contaminated by the infiltration of impurities and moisture. Therefore, pay attention to the state of the outlet end of the electric heating tube during operation to avoid leakage. accident.
