1. Introduction to type electric heating tube
Type electric heating tube The electric heating tube is an electric heating wire placed in a seamless tube, and the gap is closely filled with crystalline magnesium oxide with good thermal conductivity and insulation. Both ends of the wire are connected to the power supply through two lead-out rods. The gap is filled with magnesium oxide powder with good thermal conductivity and insulation and then shrunk. Because the electric heating tube is bent like an English letter, it is called a type electric heating tube. Type heating tubes can be used to heat liquids and air. It has a simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and corrosive liquids such as acid, alkali and salt, and is also suitable for heating and melting metals with low melting points.
2. Characteristics of type electric heating tubes
Type-type electric heating tubes have simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids and acid-base salts, and is also suitable for heating and melting metals with low melting points (lead, zinc, tin, babbitt alloy). Pipes with excellent performance can be selected according to the equipment usage environment to achieve corrosion resistance, Heat resistance, long dry burning life, rapid cooling and rapid heating and other special requirements
, the surface of the type electric heating tube is treated with special technology and seamless stainless steel to prevent dry burning explosions
, the type electric heating tube has excellent electrical properties , can improve the safety of equipment use
The internal design of the electric heating tube is optimized, and the advanced manufacturing process can ensure the use requirements and life of the equipment.
3. Design and customization of type heating tubes:
Prerequisites for design and customization: First choice must be informed of the working environment of the heating tube: air dry burning or liquid heating
If it is air dry burning, it is required Do you know how high the heating temperature is? Is there a fan blowing? What is the fan flow rate?
If the liquid is heated, is the heating medium water or other liquid? If it is other liquids, are they corrosive?
4. Instructions for ordering parameters of type electric heating pipes:
, voltage, power
, pipe diameter (usually etc.)
, single side length (excluding the length of fastener threads , if the type heating pipe needs to pass through a very thick container when installing, the thread length can be made longer)
Whether it contains fasteners, if so, the size of the fasteners and the thread length
, center distance distance (general pipe diameter, center distance must be at least greater than, pipe diameter, center distance must be at least greater than, pipe diameter, center distance must be at least greater than, pipe diameter, center distance must be at least greater than, pipe diameter, center distance must be at least greater than Greater than, the above data is for reference only)
, Electric heating wire material selection: generally iron-chromium-aluminum wire, nickel-chromium wire (generally, resistance wire, etc.). The choice between the two depends on the customer's working environment (temperature and vibration).
Precautions for the use of type five electric heating tubes:
The components are allowed to work under the following conditions: ． The relative humidity of the air is not greater than %, and there are no explosive and corrosive gases. B. The working voltage should not be greater than .times of the rated value, and the shell should be effectively grounded. C. Insulation resistance && dielectric strength:/.
The electric heating tube should be positioned and fixed. The effective heating area must be completely immersed in liquid or metal solid. It is strictly prohibited to burn in the air. When scale or carbon is found on the surface of the pipe, it should be cleaned in time before use to avoid affecting heat dissipation and shortening the service life.
When heating fusible metals or solid nitrates, alkali, bitumen, paraffin, etc., the voltage should be lowered first, and then the voltage can be raised to the rated voltage after the medium is melted.
When heating air, the elements should be arranged evenly across each other so that the elements have good heat dissipation conditions and the air flowing through can be fully heated. . Safety measures should be taken into consideration when heating nitrate salt to prevent explosion accidents.
The wiring part should be placed outside the insulation layer to avoid contact with corrosive, explosive media and moisture. The lead wire should be able to withstand the temperature and heating load of the wiring part for a long time. Excessive force should be avoided when tightening the wiring screws.
Components should be stored in a dry place. If the insulation resistance is lower than & due to long-term storage, they can be dried in an oven at about ℃, or the voltage can be reduced and heated until the insulation resistance is restored.
The magnesium oxide powder at the outlet end of the electric heating tube prevents pollutants and moisture from penetrating into the place of use, and prevents leakage accidents.
