The functional characteristics of the explosion proof electric heater and what the original components have

The explosion-proof electric heater has small volume and high power. The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high. High heating temperature: the maximum working temperature designed by the heater can reach 850 degrees C. The temperature of the outlet of the medium is uniform and the precision of temperature control is high. It has wide application and strong adaptability. The explosion-proof electric heater can be applied to explosion-proof or ordinary occasions, and the explosion-proof level can reach D II B or C, and the withstand voltage can reach 20MPa. Long life and high reliability: the explosion-proof electric heater is made of special electrothermal materials, the power load of the designed surface is low, and multiple protection is adopted to make the safety and life of the electric heater increase greatly. Fully automatic control: according to the requirement, through heater circuit design, it can realize automatic control of outlet temperature, flow and pressure and so on, and it can be networked with computer. The energy saving effect is remarkable, the energy produced by electric energy is almost 100% to the heating medium.

The size of the electric heater is small and the power heater is mainly used as a cluster tubular electric heating element.

The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high. The heating temperature is high: the heater can be designed for the highest working temperature of 850 degrees C. The temperature of the medium is uniform and the precision of temperature control is high. Wide application and strong adaptability: the heater can be applied to explosion-proof or ordinary occasions, explosion-proof grade can reach D II B grade and C grade, and the pressure can be up to 20MPa. Long life and high reliability: the heater is made of special electrothermal material, and its surface power load is low, and multiple protection is adopted, so that the safety and life of electric heater will be greatly increased. Fully automatic control: according to the requirement, through heater circuit design, it can realize automatic control of outlet temperature, flow and pressure and so on, and it can be networked with computer. The energy saving effect is remarkable, the energy produced by electric energy is almost 100% to the heating medium.

The filter of the explosion-proof electric heater consists of the simplified body, the stainless steel filter net, the transmission device, the discharge part and the electrical control part. The filtered water flows from the nozzle, through the filter screen, and through the outlet into the pipe to carry out the process cycle. During the cycle, there are many particles in the water that are intercepted by the filter. After a long time, the interception of impurities will be more and more, the filter hole is more and more small, the pressure difference between import and export, the differential pressure reaches the set value will send signals to the controller, the control system starts to rotate through the drive motor drive assembly drives the shaft, while the sewage outfall opened to remove dirt, after cleaning the system returns the initial state, the normal operation of the system. According to the function, the filter can be divided into self cleaning filter, automatic filter, brush filter and elastic filter. The general explosion-proof electric heater system adopts elastic filter, which is free from maintenance and automatic cleaning, so that the hidden trouble of filter element is blocked for a long time.
