Introduction of electric heating tube and its functional characteristics

Introduction

 

Electric heating tube, also known as heating tube, heating tube, scientific name tubular electric heater element, is a coiled heating wire (resistance wire) placed in a metal tube, and the surrounding and gap parts are filled with good heat resistance, Thermally conductive and insulating insulating powder (MgO), the two ends of the heating wire are connected with lead rods or lead wires. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. It is widely used in all kinds of saltpeter tanks, water tanks, oil tanks, acid-base tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot press molds and other devices.

 

The electric heating tube is an electrical component that specializes in converting electrical energy into heat energy. Because of its low price, easy use, easy installation, and no pollution, it is widely used in various heating occasions.

 

Function

 

Small size and high power: The heater mainly adopts the cluster type tubular electric heating element. The heat response is fast, the temperature control precision is high, and the comprehensive thermal efficiency is high. High heating temperature: The heater's design task temperature can reach 850℃. The medium outlet temperature is average, and the temperature control accuracy is high. Wide range of use and strong compliance: The heater can be used in explosion-proof or popular places. The explosion-proof grades can reach dⅡB and C grades, and the pressure resistance can reach 20MPa. Long life and high reliability: The heater is made of extraordinary electric heating materials, designed to have a low power load on the surface, and adopts multiple maintenance, which greatly increases the safety and life of the electric heater. Fully automatic control: The heater circuit is designed according to the requirements, which can facilitate the automatic control of parameters such as outlet temperature, flow, and pressure, and can be networked with computers. The energy-saving results are obvious, and almost 100% of the heat generated by the electric energy is transferred to the heating medium.
