When using electric heating tube heating tube manufacturer note have?
1, the element allows work under the following conditions: A. Air relative humidity is not more than 95%, explosive and corrosive gas. B. Working voltage should be not greater than 1.1 times that of the rating, the shell should be effectively grounded. C. Insulation resistance 1 m or more Ω dielectric strength: 2 kv / 1 min.
2, electric heating pipe should be fixed positioning, effective heating area must be completely immersed in liquid or solid metal, it is forbidden to empty fire. Heating pipe manufacturers found a scale or carbon tube body surface, should be timely clean again, lest absence made the cooling and shorten service life.
3, heating fusible metal or solid nitrate, alkali, asphalt and paraffin etc, should be used to reduce voltage, after being medium melt, can rise to the rated voltage.
4, uniform heating air element should cross arranged, make the element has good heat dissipation conditions, make the air flow can be fully heated.
5, heating security measures should be considered when nitrate, preventing explosion accidents.
Part 6, connection should be on the outside of the insulation layer, avoid contact with corrosive, explosive medium, water; Lead connection should be able to long-term bear part of the temperature and heating load, the connection screw fastening should avoid too hard.
7, components should be stored in a dry place, if long-term placed below 1 m Ω insulation resistance, can be in around 200 ℃ oven drying, or lower voltage electric heat, until the insulation resistance.
8, the electric heating tube for the magnesium oxide powder, in the use of places to avoid pollution and moisture infiltration, prevent leakage accidents.
The damage of electric heating tube
Component pressure is lower than standard values, leak current is greater than 5 ma or insulation current less than 1 m Ω, and irreversible.
Shell has a flame emission and serious corrosion of the melt, or the other are not allowed to repair the damage.
Components of the actual power than the power rating of 20%.
Electric heat pipe is specially converts electrical energy into heat energy of electrical components, due to its cheap, easy to use, easy installation, no pollution, is widely used in all kinds of electric heating.
The recovery of electric heating tube
Due to the use and long time storage reason. Components of electrical insulation performance is lower than standard values, by oven drying method, the electric insulation performance back to the standard process, and does not affect the performance of the element and normal use.
The safe use of electric heating tube
1, the electric heating allows work under the following conditions:
A. Air relative humidity is not more than 95%, explosive and corrosive gas.
B. Working voltage should be not greater than 1.1 times that of the rating, the shell should be effectively grounded.
C. Insulation resistance 1 m or more Ω, dielectric strength: 2 kv / 1 min. If running environment does not meet the above requirements, please stop using the electric heat pipe.
2, electric heat pipe should be fixed positioning, effective heating area must be completely immersed in liquid or solid metal, it is forbidden to empty fire. Found a scale or carbon tube body surface, should be timely clean again, lest absence made the cooling and shorten service life.
3, heating fusible metal or solid nitrate, alkali, asphalt and paraffin etc, should be used to reduce voltage, after being medium melt, can rise to the rated voltage.
4, uniform heating air element should cross arranged, make the electric heat pipe has good heat dissipation conditions, make the air flow can be fully heated.
5, heating security measures should be considered when nitrate, preventing explosion accidents.
Part 6, connection should be on the outside of the insulation layer, avoid contact with corrosive, explosive medium, water; Lead connection should be able to long-term bear part of the temperature and heating load, the connection screw fastening should avoid too hard.
7, the electric heat pipe should be stored in a dry place, if long-term placed below 1 m Ω insulation resistance, can be in around 200 ℃ oven drying, or lower voltage electric heat, until the insulation resistance.
8, the electric heat pipe outlet side magnesium oxide powder, for pollutants and use place to avoid moisture infiltration, prevent leakage accidents.
