Značilnosti zračnih električnih grelnikov

Gas pipeline electric heater is a device that consumes electrical energy and converts it into thermal energy to heat heating materials. Its design appearance is low power load, with multiple maintenance options, greatly improving the safety and service life of the air heater. The heater circuit can be designed according to requirements, facilitating active control of outlet temperature, flow rate, pressure and other Parametri . Učinek varčevanja z energijo je očiten, toplota, ki jo ustvarja električna energija

Pri nalogi grelnika zraka plinovod nizkotemperaturni tekoči medij vstopi v dovod skozi cevovod pod pritiskom in odpelje visokotemperaturno toplotno energijo, ki nastane v nalogi električnega grelnega materiala, s tekočo termodinamiko, poveča temperaturo ogrevalnega medija in pridobi visoko temperaturno medij, ki je potreben za odtok zračnega grelnika.

The high-pressure system inside the pipeline air heater can be turned to DCS to provide heater operation. Alarm signals such as high temperature, faults, and shutdowns can also accept automatic and shutdown operation titles issued by DCS. Moreover, the air heater system has added reliable and safe monitoring devices, but the price reference for explosion-proof air heaters is relatively visoko .

Kontrolni del grelnika zraka je instrument in ga je treba previdno prevažati med prevozom, da se izognete trkom ali trkom . razumno dvignite valjni del grelnika zraka, da preprečite deformacijo in poškodbe notranjih ogrevalnih elementov .

Del ožičenja grelnika zraka cevovoda je treba namestiti zunaj izolacijske plasti, da se prepreči stik s korozivnimi, eksplozivnimi mediji in vlago; The wire should be able to withstand the temperature and thermal load of the connection area for a long time, and excessive force should be avoided when tightening the connection screws. The pipeline air heater components should be stored in a dry place. If the insulation resistance is below 1, due to long-term storage, the insulation resistance is below 1 ω, It can be dried in an oven at 200℃or segreva z znižanjem napetosti, dokler se izolacijski upor ne obnovi .
