Vilka typer av vanliga elektriska värmerör finns det?

Flange electric heating tube (also called plug-in electric heater): U-shaped tubular electric heating element is adopted. According to the heating medium design specification, it is assembled on the flange cover according to the power configuration requirement, inserted into the material to be heated, and the heating element is working. The large amount of heat emitted is transferred to the heated medium to raise the temperature of the medium to the Önskade processkrav . När medeltemperaturen når det inställda värde som krävs av processen, justerar kontrollsystemet utgångseffekten för den elektriska värmaren enligt temperatursensorsignalen och utför temperaturkontrollen på den resistiva belastningen för värmeelementet . Mediumtemperaturen görs enhetlig för att uppfylla de nödvändiga kraven; when the heating element is over-temperature or low-level, the interlocking protection device of the heating element immediately cuts off the heating power source to avoid burning of the heating element and prolongs the service life. The flange electric heating pipe is mainly used for heat preservation and heating of various storage tanks, containers and fuel tanks in petroleum, chemical, food, machinery and other industries. Anslutningsmetoden kan flänsas eller gängas sluttätning [1] .

Fin elektriska värmningsrör

A finned electric heating tube is a type of electric energy that is converted into heat to heat a material to be heated. During operation, the low-temperature fluid medium enters its input port under the action of pressure through the pipeline, along the specific heat exchange flow path inside the electric heating vessel, and uses the path designed by the fluid thermodynamics principle to take away the high-temperature heat energy generated in the work of the electric heating Element . Temperaturen på det uppvärmda mediet höjs, och det hinnade elektriska värmningsröret erhålls som ett högtemperaturmedium som krävs av processen . Finned

Titanelektriskt värmningsrör

The titanium electric heating tube is made of titanium tube, and the electric heating alloy wire is evenly distributed along the central axis of the tube. The gap is filled with magnesia sand with good insulation and thermal conductivity. The ends of the tube are sealed with silica gel or ceramic. Highly corrosive liquid for components. Titanium electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Widely used in a variety of highly corrosive liquids. Titanium has a small specific gravity and is widely used in heating water, nitrate solution, acid solution and alkali solution. It has been proved that Titan har hög effektivitet och lång livslängd i applicering av antikorrosionsutrustning . Det påverkar inte pläteringslösningen i applicering av elektropläteringsutrustning . förbättrar kraftigt effektiviteten i elektropläteringsindustrin . Den effektiva längden för uppvärmningselementet måste vara fullständigt infallda i vätskan [1]

Kvarts elektriskt värmningsrör


Kvartsvärmningsrör, oftast används är kolfiberkvartsvärmningsrör .

Carbon fiber heating tube [3], also known as carbon fiber electric heating tube, infrared heating tube, infrared electric heating tube, carbon fiber infrared electric heating tube, carbon fiber infrared heating tube and so on. It is placed in a quartz tube with a carbon fiber filament. The tube is vacuum-sealed, and a voltage is applied to the carbon fiber filament to cause the carbon fiber Filament för att generera värme . Företagets produkter använder importerade kolfibervärmeelement, med fördelarna med stor effektmarginal, hög temperaturmotstånd, hög värmekapacitet, lång livslängd och kraft kan justeras vid vilja .}

Strålande elektriska värmningsrör

The radiant heating tube is used to enclose the electric heating element in the protective sleeve to generate heat, and the heat is radiated to the lining and the workpiece to be processed indirectly by the sleeve, and is widely used in various heating furnaces of the heat treatment industry. The electrothermal alloy material used in the radiant heating tube should have a high electrical resistivity and a high electrothermal conversion rate. Since the radiant tube is placed in the casing, the heat transfer process is different from that of the general open type electric heating element, and the heat shielding is large, and the temperature of the component must be controlled during the heating process to prevent the component from being overheated. When the radiant tube is closed and heated, the surface temperature of the electric heating element is about 100℃C - 150 grad C högre än ugnstemperaturen . Därför är det i valet av material att analysera ugnstemperaturen, temperaturen inuti ugnen och välj rätt värmematerial [1] .}
