Small volume and large power: the heater mainly adopts bundle tubular electric heating element. Rapid thermal response, high temperature control accuracy and high comprehensive thermal efficiency. High heating temperature: the maximum design task temperature of the heater can reach 850 ℃. The medium outlet temperature is average and the temperature control accuracy is high. Wide application limitation and strong compliance: the heater can be used in explosion-proof or popular places, with explosion-proof grades up to D Ⅱ B and C, and pressure resistance up to 20MPa. Long service life and high reliability: the heater is made of special electric heating materials, designed with low external power load and multiple maintenance, making the safety and service life of the electric heater greatly increased. Fully active control: according to the requirements of the heater circuit design, it can facilitate the completion of the outlet temperature, flow, pressure and other parameters of active control, and can be connected with the computer network. The result of energy saving is obvious. The heat generated by electric energy is almost 100% transferred to the heating medium.
The fluid explosion-proof electric heater is a kind of heat energy which is used to heat the materials to be heated. In the task, the low-temperature fluid medium enters its inlet under the pressure effect through the pipeline, along the specific heat exchange channel inside the electric heating vessel, and uses the way designed by the principle of fluid thermodynamics to take away the high-temperature heat energy occurred in the task of the electric heating element, so as to raise the temperature of the heated medium, and the outlet of the electric heater can obtain the high-temperature medium required by the process. The internal control system of the electric heater actively regulates the output power of the electric heater according to the temperature sensor signal of the output port, so as to make the medium temperature of the output port average; when the temperature of the fever element is over temperature, the self-supporting overheat maintenance and installation of the fever element cut off the heating power supply immediately to prevent the overheating of the heating material from causing metamorphosis, coking and carbonization, and in severe cases, the fever element is burnt out, which can be used for prolongation Service life of extension heater.
Leakage problem editor
Electric leakage of heating pipe and its solution:
Reason
