Instructions for selection:
The components are allowed to work under the following conditions:
, the relative humidity of the air is not greater than 1, and there are no explosive and corrosive gases
/>, the working voltage should not be greater than .times of the rated value, and the shell should be effectively grounded.
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. Avoid using excessive force when tightening the wiring screws. .
Components should be stored in a dry place. If the insulation resistance is lower than that 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.
When heating liquid, the effective heating area must be completely immersed in the liquid. If scale or carbon is found on the surface of the tube, 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, asphalt, paraffin, etc., the voltage should be lowered first, and then the voltage can be raised to the rated voltage after the medium melts.
When heating nitrate salt, safety measures should be taken into consideration to prevent explosion accidents.
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.
Performance instructions for tubular electric heating elements
Tubular electric heating elements are a combination of metal tubes, spiral resistance wires and crystalline magnesium oxide with good thermal conductivity and insulation. They can be used to heat air, oil , water, preheating metal molds, melting salt, alkali and low melting point alloys, etc. It has the advantages of high thermal efficiency, long life, good mechanical strength, easy installation, and safe use.
Tubular electric heating elements can be bent into shapes such as wavy, spiral, etc. as needed, and the cross-sections of the elements can be divided into circular, oval, rectangular, triangular and other categories.
