The internal control system of the electrical heating tube automatically adjusts the output power of the heating tube based on the temperature sensor signal at the output port, ensuring uniform medium temperature at the output of the air electrical heating tube. In case the heating element of the air electrical heating tube overheats, the independent overheat protection device of the heating element immediately cuts off the heating power, preventing overheating of the heating material in the air electrical heating tube, which could lead to coking, deterioration, carbonization, and in severe cases, damage to the heating element. This effectively extends the service life of the electrical heating tube.
Common issues with electric heaters, such as external leakage, liquid leakage, and significant pressure drop, as well as heating temperature malfunctions, require knowledge of their solutions. Timely resolution is crucial; how should one proceed specifically?
Firstly, let's discuss leakage. The main areas where leakage occurs are between the plates at the sealing points, in the secondary sealing leakage slots of the plates, and at the interior of the end plates and the clamping plate. Next, let's talk about the high pressure drop. The pressure drop at the inlet and outlet of the medium exceeds the design requirements, sometimes even many times higher than the design values, severely affecting the system's requirements for flow and temperature. In heating systems, if the pressure drop on the hot side is too great, the primary side flow will be seriously insufficient, meaning the heat source is inadequate, resulting in the temperature on the secondary side not meeting the required standards.
An electric heater converts electrical energy into heat to heat the required materials. During operation, the low-temperature fluid medium enters through the input port under pressure and flows along the specific heat exchange channels inside the electric heating vessel.
Our design utilizes the principles of fluid thermodynamics in air electric heaters to remove the high-temperature thermal energy generated by the electric heating elements within the air electric heater tubes. This raises the temperature of the heating medium, resulting in the outlet of the electric heater tubes achieving the high-temperature medium required by the process.
