Matters Needing Attention In Electric Heaters Using
- Nov 26, 2016 -

Matters needing attention in using
1, electric heating elements allows to work under the following conditions:
A, relative air humidity not more than 95%, no explosive and corrosive gases. (Except for the explosion-proof electric heater)
B, operating voltage should not exceed the rated value of 1.1 times, the shell shall be effectively earthed.
C dielectric strength, insulation resistance ≥ 1M: 2KV/1min.
2, heating pipe fixed positioning, effective heat need to be fully immersed in the liquid or solid, no burning.
When he found the scale or soot on the surface of the pipe body, should be cleaned in time, lest the noon heat and shorten the service life.

3, heating the fusible metal or solid nitrate, alkali, bitumen, paraffin waxes, and so on, should reduce the use of voltage, medium melting, rising to its rated voltage.
4, heating the air component should be crossed evenly so that components have good cooling conditions, make the flow of the air can be fully heated.
5, the heat should consider safety measures for nitrate, explosion prevention.
Part .
6, wiring insulation layer should be placed on the outside, avoid contact with corrosive or explosive media, water; lead wire should be able
