Electric heating tube is a tubular electric heating element, which is composed of metal tube spiral resistance wire and crystalline magnesium oxide powder. In the stainless steel seamless tube evenly distributed high temperature resistance wire, in the gap part filled with good thermal conductivity and insulation performance of crystalline magnesium oxide powder, the structure is not only advanced, high thermal efficiency, uniform heating, high temperature resistance wire current through, the heat generated through the magnesium oxide powder to the surface of the metal tube, and then transmitted to the heated part or air to achieve the purpose of heating.
Main technical difficulty: Although stainless steel electric heating body is a relatively mature technology, but stainless steel material has its particularity, welding process is also more complicated, therefore, in the structural design of the heating body, special attention should be paid to the internal stress caused by uneven heat transfer of stainless steel, focus on this aspect to do some special flexible design, at the same time must do relevant tests to verify the reliability of this design, so as to ensure the use of the product, give full play to the advantages of stainless steel heating tube.
Peculiarity:
1. Most of the hot air circulates in the box, which has high thermal efficiency and saves energy.
2. Using the forced ventilation effect, the box is equipped with an adjustable air distribution plate, and the material is dried evenly. Heat sources can use steam, hot water, electricity, far infrared, a wide range of choices.
3. The whole machine has low noise and stable operation. Temperature automatic control, easy installation and maintenance.
4. Wide range of application, can dry all kinds of materials, is a general drying equipment.
