Because of the various forms of electric heaters, it is not easy for customers to choose a suitable one from them. At least they must have a basic understanding of a common electric heater. Take the flange-type electric heater as an example, do you understand its structure, characteristics and principle?
Starting from the analysis of the reasonable layout of the flange-type electric heater, the machine equipment welds a dry heating tube to the flange plate. Most of them use argon arc. Naturally, you can also use the method of tightening the equipment. The upper welding consists of standard parts, which is convenient to complete centralized heating.
In addition, the sealing of standard parts of the flange-type electric heater is made of scientific research processing technology, which is extremely convenient to replace and replace a single piece, which greatly saves the maintenance cost afterwards. And the overall structure will become more and more compact; moreover, because the electric heating pipe of the wafer check valve is short and assembled, the reliability is good, and the installation does not require a support frame.
The second is the characteristics of the flange-type electric heater. Compared with other electric heaters, its surface output power is large, which makes the gas heating surface load 2 to 4 times. With this point, the key to the equipment is Open and closed aqueous tank and breathing system.
U-shaped tubular electric heating materials are used in the flange-type electric heaters, and according to the design standards of different heating media, they are installed on the flange cover according to the output power configuration regulations, and inserted into the raw materials to be heated. When the hot components are in operation, a lot of heat is transferred to the heated medium to increase the temperature of the medium, so as to meet the required processing technology regulations.
When the temperature of the medium reaches the preset value specified by the processing technology, the automatic control system of the electric heating tube of the clamp check valve adjusts the power of the electric heater after PID calculation according to the data signal of the temperature sensor, and the resistor of the hot component The temperature control is completed by the sexual load, so that the temperature of the medium is symmetrical and meets the required regulations.
