Basic principle of industrial air heater and its application in dry and agitated industry

Industrial air heater It is an essential machine equipment in the development of intelligent industry, which is composed of blower motor, electric heater and control circuit. Among them, portable electric air heater, universal industrial air heater, medium pressure plate industrial air heater, circulating industrial air heater, high pressure industrial air heater, large-scale industrial air heater, metal mold casting industrial air heater, large and medium-sized stainless steel plate industrial air heater are widely used in electronic devices, food, pharmaceutical industry, packaging and other fields. Industrial air heater is the best choice for industrial pyrogen upgrading. It is the best warm air source for heating transport furnace, dryer equipment, drying box, packaging machine and other automation equipment. It has a very broad application and promotion market prospect.

Basic principle of industrial air heater

After the power supply is connected, the blower motor blows the gas to the electric heater, so that the gas is evenly distributed from the inside and both sides of the spiral heating wire. After the heating wire is connected with the power supply, the heat exchange is carried out with the strong cold air, and the air temperature of the vent is higher. The K-type thermocouple at the vent will immediately feedback the air inlet temperature to the temperature controller. The instrument panel monitors the specific temperature in operation according to the set temperature, and transmits the relevant information back to the intermediate relay, so as to control whether the electric heater is in operation. In addition, the exhaust fan can use the exhaust volume controller (soft starter, intake valve) to adjust the size of exhaust air volume of blowing gas, so as to complete the control of operating temperature and exhaust air volume. In addition, the electric heater also set the overheat maintenance control circuit for the exhaust fan air inlet and motor, and set the emergency brake power switch for the main power circuit, which further improved the maintenance of the machine equipment.

influence Function of industrial air heater following:

1. Raw materials of industrial air heater: the machinery and equipment are generally made of aluminum alloy raw materials, because the aluminum alloy raw materials do not contain iron, so it is not easy to air oxidation, together with a long service life. The electric heater made of aluminum alloy raw materials not only has firm quality, but also can ensure its excellent function. It is not easy to damage the application effect of machinery and equipment due to long-term application.

2. Heating wire of industrial air heater: heating wire is the most important part of electric air heater. The main suspension in the machine and equipment can release the starting heat evenly and satisfy the application requirements. However, the heating wire in many electric air heaters is often broken, resulting in the reduction of the function of the machine and equipment, which can not achieve the ideal application effect. Therefore, customers in the choice of electric heater, must attach great importance to the quality of heating wire.

3. Heating core of industrial air heater: hair ironing core is a key part of equipment, which can maintain the application life of heating wire and achieve ideal application effect. However, the application life of hair ironing core is short, and it is impossible to ensure the application of heating wire, so the application effect of machinery and equipment for all personnel is reduced.

4. Industrial air heater maintenance equipment: there are maintenance equipment inside the electric heater to prevent long-term application of air burning, and prevent internal parts from damaging the application of machine equipment due to empty burning. Therefore, when selecting, we should attach great importance to whether there is maintenance equipment inside the electric heater and whether it has good application effect.
