Introduction of flange type electric heater:
Mainly used for heating in open and closed solution tanks and circulation systems. Has the following advantages:
The surface power is large, so that the gas heating surface load is 2 to 4 times.Highly intensive and compact structure. Because the overall is short and dense, the reliability is good, and the installation does not require a bracket.Most of the combined type adopts argon arc welding method to make the electric heating tube on the loop flange, and can also use the method of tightening equipment, that is, each electric heating tube is welded with standard parts. Then use a nut to clamp with the flange cover. The pipeline is welded to the standard parts by argon arc, which will never leak. The sealing of standard parts adopts scientific research technology. It is extremely convenient to replace and replace a single root, which greatly saves the maintenance cost afterwards.Choose imported and high-quality Chinese raw materials. Scientific research production technology and strict quality management ensure the excellent electrical characteristics of the electric heating tube.
Overview and working principle of flange type electric heater:
Flange-type electric heater (also called plug-in electric heater): U-shaped tubular electric heating material is used. According to the design standard of different heating media, it is installed on the flange cover according to the power allocation regulations and inserted into the raw material to be heated When the heating element is in operation, a lot of heat that needs to be transmitted is transmitted to the heated medium to increase the temperature of the medium, so as to meet the required process regulations. When the temperature of the medium reaches the preset value specified by the process, the control system adjusts the power of the electric heater after PID calculation based on the temperature sensor signal, and completes the temperature control of the resistive load of the heating element. Make the temperature of the medium uniform and meet the required regulations; when the heating element is overheated or the liquid level is low, the interlocking protection device of the heating element immediately disconnects the heating switch power to prevent the heating element from burning and increase the service life.
Application scope of flange electric heater:
Flange-type electric heaters are mainly used for heat insulation and heating of raw materials in various storage tanks, utensils, and automobile fuel tanks in the fields of crude oil, chemical plants, food, machinery and equipment. The interface method can adopt flange type or external thread internal hole sealing。
