Attention should be paid to the requirements for the environment of explosion-proof electric heaters

Requirements for the operating environment of explosion-proof heaters: To ensure that the efficiency and service life of explosion-proof pipeline electric heaters are not affected, attention should be paid to the normal operating environment. Explosion proof electric heaters should be used in normal environments. In daily use, explosion-proof electric heaters have strict requirements for the operating environment. To avoid affecting the efficiency and service life of explosion-proof electric heaters, these environmental requirements should be given attention.

(1) Before heating, the relevant components of each explosion-proof electric heater should be checked to ensure they are in normal condition. The electric heater can only be put into use after all inspections have been carried out without any problems. (2) The power supply voltage should be consistent with the voltage of the explosion-proof electric heater. Moreover, it needs to be correctly connected to the control circuit. (3) All wiring terminals in pipeline electric heaters should be checked for firmness and grounded.

(4) At the inlet end of the explosion-proof fluid electric heater, a filter should be installed to prevent foreign objects from entering the heating tube, which may affect the service life and heat dissipation performance of the electric heater. Moreover, the filter should be cleaned regularly. (5) The wiring terminals of the flue gas pipeline electric heater should have a certain distance left during installation, generally not less than 1 meter, so as to facilitate maintenance and repair work.

For explosion-proof electric heaters, heat is generated and transmitted by the electric heating element immersed in thermal oil. The thermal oil is used as the medium, and a circulation pump is used to force the thermal oil to undergo liquid-phase circulation, transferring heat to one or more heating equipment. After unloading by the heating equipment, the heat is returned to the heater through the circulation pump, then absorbed and transferred to the heating equipment. This cycle is repeated to achieve continuous heat transfer, raise the temperature of the heated object, and meet the heating process requirements.
