1. Introduction to type-type electric heating tubes
Type-type electric heating tubes place electric heating wires in seamless metal tubes (carbon steel tubes, titanium tubes, stainless steel tubes, copper tubes), and fill the gaps tightly It is made of crystalline magnesium oxide with good thermal conductivity and insulation. The two ends of the electric heating 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. Therefore, The electric heating tube is bent like an English letter, so it is called a type electric heating tube. Type heating tubes can be used to heat liquids and air. The size is determined according to customer requirements, power matching and installation space. Type electric heating tubes are used in shoemaking machinery, chemical machinery, pharmaceutical machinery, electric ovens, centrifuges, battery factories, storage battery factories, garment factory steam ovens, automated electronic equipment, wave soldering, reflow soldering machinery, washing and drying machinery and refrigeration equipment Air and other media are heated. Yancheng Zhaishi Electric Heating and Electrical Factory has rich experience in manufacturing electric heating pipes. It can carry out scientific and targeted design according to different usage environments of electric heating pipes and customer requirements to improve the safety and life of electric heating pipes.
2. Characteristics of electric heating tube
Simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. The electric heating tube can be used for heating various liquids and acid-base salts. It 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 environment in which the equipment is used to achieve resistance to Corrosion resistance, heat resistance, long dry burning life, rapid cooling and rapid heating and other special requirements
, the surface of the electric heating tube is treated with special technology and seamless stainless steel to prevent dry burning explosions
, excellent electrical performance, Improve the safety of equipment use
The internal design of the electric heating tube is optimized and the advanced manufacturing process ensures the equipment use requirements and lifespan.
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 blower blowing? What is the fan flow rate?
If it is heating liquid, 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)
, Appearance material selection: The main materials are carbon steel, stainless steel with coating (anti-scale treatment), (commonly known as: ), titanium tube, etc.
, electric heating wire material Choice: generally iron-chromium-aluminum wire (Beijing Shougang), nickel-chromium wire (generally, resistance wire, etc.). The choice between the two depends on the customer's working environment (temperature and vibration).
5. Calculation of the calorific value of the type heating tube
You can use a voltage regulator to change the calorific value by changing the input voltage and current
The calorific value is proportional to the square of the voltage and proportional to the square of the current
br/> When the voltage changes to the original /, the calorific value becomes /
When the current changes to the original /, the calorific value also changes to /
6. How to verify the high-quality heating tube?
The most intuitive way to verify the quality of the electric heating tube is: first clean the surface of the electric heating tube, then connect to the AC power supply, and dry-burn in the air. When the surface turns red, cut off the power. After the electric heating tube has completely cooled, use Wipe it with a napkin. If there is no black oxidized powder on the white paper (it has not reacted with oxygen in the air), it indicates that it is a high-quality electric heating tube.
Carbon fiber heating element is the most competitive high-tech material in this century. Its emergence has set off a new revolution in the field of electric heating. It will become an inevitable trend for carbon fiber heating element to replace metal heating element.
7. Precautions for electric heating tubes:
The components are allowed to work under the following conditions:
The relative humidity of the air is not greater than %
The operating voltage is not greater than . times of the rated value, the shell It should be effectively grounded.
When the heating medium is liquid, the effective length (or) of the element must be completely immersed in the liquid. The heating part of the element should be at a certain distance from the container wall, generally && or above.
Components that heat liquids must not be used to heat gases or solid objects.
For components that heat liquids, if scale or carbon is found on the surface of the tube, it should be cleaned before use to avoid affecting the service life of the component and reducing thermal efficiency.
For heating when smelting light metals or nitrates, alkali, asphalt, paraffin, etc. are in a solid state, the voltage should be reduced to start, and the rated voltage can only be raised to the rated voltage after all the solid heating media are melted.
When heating nitrate salt, safety measures should be taken into consideration to prevent explosion accidents.
The component wiring part should be placed outside the insulation layer and heating room, and avoid contact with corrosive and explosive gases. The outlet end must be kept dry and clean to avoid flashover or short circuit. Do not use excessive force when wiring.
A small amount of paste may overflow from the end of the component. This is the sealing material and does not affect use. Just wipe the overflow clean after the power is turned off.
Components should be stored in a room with good air circulation, relative humidity not greater than %, and no corrosive gases.
After the component has been used for a period of time and has not been used for a long time and has become damp, and its cold insulation resistance is lower than megohms, the component can be baked in a drying oven with a temperature of about 100 ℃, or the voltage can be reduced and directly heated by electricity to remove moisture until it returns to normal.
