1. Product description:
The dry-fired fin-type electric heating tubes produced by Yancheng Zhaishi Electric Heating and Electrical Factory are made of high-quality stainless steel, modified protactinium oxide powder, high-resistance electric heating alloy wire, stainless steel radiator and other materials , produced through advanced production equipment and technology, and subject to strict quality management, its various electrical performance indicators are much higher than B/ and B industry standards. This series of products can be installed in blower ducts or other heating situations with static and flowing air.
2. Performance characteristics
Dry-burning fin-type electric heating tubes are made by wrapping metal heat sinks on the surface of ordinary components. Compared with ordinary components, the heat dissipation area is expanded ~ times, that is, the surface allowed by the fin components The power load is ~ times that of ordinary components. Due to the shortened length of the element, the heat loss is reduced. Under the same power conditions, it has the advantages of fast heating, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small heating device, and low cost. Reasonable design according to user requirements for easy installation. Products are widely used in machinery manufacturing, automobiles, textiles, food, home appliances and other industries, especially in the air conditioner air curtain industry. Titanium electric heating tube and titanium steam tube titanium material has small specific gravity, high strength and corrosion resistance. Practice has proven that titanium has high efficiency and long life in the production and application of anti-corrosion equipment. In the application of electroplating equipment, it does not affect the plating solution and can greatly improve the efficiency of the electroplating industry.
3. Design and customization of dry-fired fin heating tubes:
Prerequisites for design and customization: First choice must be informed of the working environment of the heating tube: air dry heating or liquid heating
If it is air Dry roasting, need to 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 dry-fired finned electric heating tube parameters:
, voltage/power, length and shape of the heating tube, fin width, heating tube and fin material, whether fasteners and Fastener size, customer's special requirements, etc.
, pipe diameter (usually equal to etc.)
, single side length (excluding the length of the fastener thread, if the type heating pipe needs to pass through a very thick container when installing, the thread length can be length)
, whether it contains fasteners, if so, the size of the fasteners and the thread length
, the center distance (generally the pipe diameter, the center distance must be at least greater than the pipe diameter, the center distance It must be at least greater than, the pipe diameter, the center distance must be at least greater than, the pipe diameter, the center distance must be at least greater than, the pipe diameter, the center distance must be at least greater than, the above data is for reference only)
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).
5. Precautions for the use of dry-fired finned 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.
