How to use heater

1, fully understand the use of electric heat pipe environment, is medium conduction or infrared radiation.

2. Select the electric heat pipe with appropriate power and pay attention to the load problem of power on the premise of ensuring the effective use temperature.

3, fully understand the use of heat pipe temperature requirements, choose the appropriate power of the heat pipe, in general, the power is large, fast heating, fast heating, and vice versa.

4. Dry heating is strictly prohibited on the water-fired electric heat pipe, especially the immersed electric heat pipe.

5, dry heat pipe to pay special attention to the use of the environment to dissipate heat effect, divided into the problem of still air and flowing air.

6. Fully understand the operating voltage of the electric heat pipe. Generally, the voltage of the electric heat pipe is 220V and 380V.

7. Fully understand the connection mode of electric heat pipe, usually star connection and triangle connection, single electric heat pipe can be connected to 220V or 380V, and multiple electric heat pipes can be connected to 380V voltage.

Steps/methods

1. Components are allowed to work under the following conditions: A.

Air relative humidity not more than 95%, no explosive and corrosive gas.

B.The operating voltage shall not be greater than 1.1 times the rated value and the housing shall be effectively grounded.

C.Insulation resistance 1 m or more Ω dielectric strength: 2 kv / 1 min.

2. The electric heat pipe shall be fixed in position. The effective heating zone shall be immersed in liquid or metal solid.

If scale or carbon is found on the surface of the pipe, it should be cleaned and reused in time to avoid heat dissipation and shorten the service life.

3. When heating fusible metal or solid nitrate, alkali, leach, paraffin, etc., the service voltage shall be reduced first, and the rated voltage shall be increased only after the medium is melted.

4. When heating the air, the components should be evenly arranged across each other, so that the components have good heat dissipation conditions and the flowing air can be fully heated.

5. Safety measures should be taken into consideration when heating saltpeter to prevent explosion accidents.

6. The wiring part shall be placed outside the insulation layer to avoid contact with corrosive, explosive media and water;

The connection should be able to withstand the temperature and heating load of the connection part for a long time.

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. Magnesium oxide powder at the outlet of the electric heat pipe can be used in places to avoid contamination and water infiltration to prevent electric leakage accidents.

The END

Matters needing attention

The most intuitive way to verify the advantages and disadvantages of the electric heat pipe is: first wipe the surface of the electric heat pipe, then connect the ac 220V power supply, dry burn in the air, the surface redness after power failure, after the electri
