1.Specifications and external dimensions: see table1And the picture1-2

SRYType tubular electric heater:

2.Allowable error of working voltage: not greater than its rated value1.1Twice. The casing should be effectively grounded.

3.Working environment: Relative humidity not exceeding95%No explosive, flammable, or corrosive gases.

4.Metal tube material:10Number steel.

5. Operating Temperature100℃。

6.SRY2TypeSRY4The work pressure of the type is less than0.6MPa.

7.Fuel tank opening: ≥ φ65.

3、 Usage, maintenance and precautions:

1.Dimensions in the external dimension diagram“B”It must be completely immersed in oil to avoid burning out the components. The heated oil should be non corrosive.

2. When melting solid oils such as asphalt and paraffin, the voltage should be reduced and then increased to the rated voltage after melting. To prevent heat concentration from reducing the lifespan of components.

3. When carbon deposits are found on the surface of the pipe, they must be removed completely before use to avoid reducing efficiency and even burning out components.

4.Components should be stored in a dry place. If the insulation resistance drops below due to long-term storage1At megaohms, it can be200Dry in an oven at around ℃ for several hours (or apply low voltage to the components for several hours) to restore insulation resistance.

BRY2型 BGY2，BGY4,Precautions for Heater
1The components are allowed to operate under the following conditions:
AThe relative humidity of the air is not greater than95%No explosive or corrosive gases. (Excluding explosion-proof heaters)
BThe working voltage should not exceed the rated value1.1The shell should be effectively grounded.
CInsulation resistance≥1MΩdielectric strength:2KV/1min.
2Electric heating tubes should be properly positioned and fixed,The effective heating area must be completely immersed in liquid or metal solid, and empty burning is strictly prohibited. When scale or carbon deposits are found on the surface of the pipe body, they should be removed and reused in a timely manner to avoid affecting heat dissipation and shortening the service life.
3When heating molten metals or solid nitrate, alkali, asphalt, paraffin, etc., the operating voltage should be reduced first, and only after the medium melts can it be raised to the rated voltage.
4When heating air, the components should be arranged in a cross and even manner to provide good heat dissipation conditions, so that the air flowing through can be fully heated.
5When heating nitrate, safety measures should be considered to prevent explosion accidents.
6The 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, and excessive force should be avoided when tightening the wiring screws.
7The components should be stored in a dry place. If the insulation resistance is lower due to long-term storage1MΩAt that time, it is possible to200Dry in an oven at around ℃, or reduce the voltage and heat with electricity until the insulation resistance is restored.
8The magnesium oxide powder at the outlet of the electric heating tube should be protected from pollutants and moisture infiltration in the usage area to prevent leakage accidents.
