And when in use, the shell should be in contact with the ground and cannot be suspended. There are many types of electric heaters, except for the explosion-proof type, ordinary electric heaters should pay attention to the humidity of the air when used. After using it for a period of time, it is necessary to clean it regularly, otherwise it will also affect the operation of the electric heater. Used for heating, insulation, and heating of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the principle of fluid thermodynamics is used to uniformly remove the huge heat generated during the operation of the electric heating element, so that the temperature of the heated medium meets the process requirements. The performance of electric heaters is improving, and their safety and reliability have also been improved. However, when using them, attention should be paid to some details and how to protect them. Improper use can also reduce the lifespan of electric heaters. For example, the wiring area should be carefully placed and not in contact with corrosive substances such as oil or water.

The calculation of heating power includes the following three aspects:

● Power during operation

● Power at startup

● Heat loss in the system

All accounting should be considered in very adverse circumstances:

● Very low ambient temperature

● Short operating cycle

● High operating temperature

A large component of heating medium (active medium has a large flow rate)

Process of calculating heater power

Draw a heating process flowchart based on the manufacturing process (without involving material form and standards).

Calculate the heat required for the manufacturing process.

Calculate the amount of heat and time required for the system to start.

Redraw the heating process flowchart, consider appropriate safety factors, and confirm the total power of the heater.

Determine the sheath material and power density of the heating element.

Determine the form, size, and quantity of the heater.

The power supply and control system for the resolution heater.

There are many types of electric heaters, except for the explosion-proof type, ordinary electric heaters should pay attention to the humidity of the air when used. After using it for a period of time, it is necessary to clean it regularly, otherwise it will also affect the operation of the electric heater An electric heating tube is a structure in which high-temperature resistance wires are uniformly distributed inside a seamless stainless steel tube, and crystalline magnesium oxide powder with good thermal conductivity and insulation properties is densely filled in the gaps. This structure is not only good and has high thermal efficiency, but also generates uniform heat. When current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the metal tube through the crystalline magnesium oxide powder, and is then transferred to the heated element or air, achieving the purpose of heating.
