What Is The Working Principle Of The Flange Heating Element?
The flange heating element adopts a U-shaped tubular electric heating element. According to the heating design specifications of different media, it is assembled on the flange cover according to the power configuration requirements, and the material to be heated is inserted. A large amount of heat generated by the heating element is transferred to the heated medium. Increase the temperature of the medium to meet the required process requirements. When the medium temperature reaches the set value required by the process, the control system adjusts the output power of the electric heater according to the temperature sensor signal, and controls the resistance load of the heating element. Make the temperature of the medium uniform and meet the required requirements; when the heating element is overheated or the liquid level is low, the interlocking protection device of the heating element immediately cuts off the heating power supply to prevent the heating element from burning out and prolong its service life.
(Note: The flanges of explosion-proof flange electric heating elements are generally divided into threaded flanges and flat flanges. The sizes of threaded flanges are generally 1 inch, 1.2 inches, 1.5 inches and 2 inches. Threaded flange pipes are generally suitable for Low-power heating, the general power is set to several kilowatts to more than ten kilowatts. Flat flanges vary in size from DN10 to DN1200, and different powers are designed according to customer requirements. Generally, high-power flanged electric heating elements are flat flanges. From a few kilowatts to hundreds of kilowatts.
Features of flange heating element application:
1. Combination explosion-proof flange electric heating elements mostly use argon arc welding to connect the electric heating elements to the flange, and it can also be in the form of a fastening device, that is, each electric heating element is welded with fasteners. Then lock the flange cover with a nut. The pipes are welded with argon arc welding fasteners and do not leak. The process of fastener sealing. It is very convenient to replace a single one, which greatly saves the maintenance cost in the future.
2. Choose imported and domestic high-quality materials. Strict production technology and quality management ensure the superior electrical performance of the element.
3. High surface power.
4. Highly dense, compact structure. Because the whole is short and dense, the stability is good, and the installation does not need a bracket.
