Structure and working principle of pipeline electric heater

(1) Pipe heater structure

The water pipe heater is composed of several parts such as multiple tubular electric heating elements, a cylinder, and a guide plate. The tubular electric heating element is a high-temperature resistance wire placed in a metal tube, and the gap is tightly filled with crystalline magnesium oxide powder with good insulation and thermal conductivity. The tubular electric heating element is used as a heating element, which has the characteristics of advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance, and wear resistance. A guide baffle is installed in the cylinder to ensure that the water is heated evenly during circulation.

(2) Working principle

The water pipe heater uses a digital temperature regulator, a solid-state relay, and a temperature measuring element to form a measurement, regulation, and control circuit. During the electric heating process, the temperature measuring element sends the water pipe heater outlet temperature electrical signal to the digital temperature regulator for amplification, and displays the measured temperature value after comparison. At the same time, it outputs the signal to the solid-state relay input end, thereby controlling the heater, so that the control cabinet has good control accuracy and regulation characteristics. The interlocking device can be used to remotely start and shut down the water pipe heater.

Pipe Heater Features

The pipe heater utilizes a stainless steel cylinder, which is compact, takes up little space, and is easy to move. It also offers strong corrosion resistance. A thick insulation layer between the stainless steel inner and outer shell minimizes heat loss, maintains temperature, and saves energy.

The main components of the high-quality heating element (stainless steel electric heating tube) are made of imported materials and are manufactured using advanced production equipment and processes. This ensures maximum performance when used with different voltages. Its insulation, pressure resistance, and moisture resistance all exceed national standards, ensuring safe and reliable use.
