Pipeline electric heaters are composed of multiple tubular electric heating elements, a cylinder, a deflector and other parts. Tubular electric heating elements are high-temperature resistance wire placed in metal tubes, and the crystalline magnesium oxide powder with good insulation and thermal conductivity is tightly filled in the gap.Pipeline heaters have the characteristics of corrosion-resistant, wear-resistant.
1.The pipeline electric heater adopts the digital display temperature regulator, solid state relay and temperature measuring element to measure, adjust and control the loop. During the electric heating process, the temperature measuring element sends the electrical signal of the outlet temperature of the water pipeline electric heater to the digital display temperature adjustment. The instrument is amplified, and the measured temperature value is displayed after comparison. At the same time, the output signal is sent to the input end of the solid state relay, so as to control the heater, so that the control cabinet has good control accuracy and adjustment characteristics.
2.The characteristics of pipeline electric heaters:
High temperature: up to 850 ℃, the shell is only about 50 ℃.
High thermal efficiency: up to 90% or more.
Fast heating and cooling speed: up to 10℃/S, fast and stable adjustment. The phenomenon of temperature lead and lag is eliminated, and the temperature is automatically controlled without drift.
Stable performance: The heating element is made of special alloy material, which has good mechanical properties and strength under the impact of high-pressure air flow, and is suitable for long-term continuous heating.
Durable: according to the formal process, the service life can reach more than ten years.
Small size: occupies a small space, suitable for various installation sites.
