Electric heating tube heating speed is controlled by what to do

Electric heating works to dry wood, paper, printing and dyeing, paint, etc. ; Melting heat of saltpeter and other salt substances; Lead melting low melting point alloy, such as melting furnace, molten tin stove, etc. Building heating; Heat flow of air and static air; Infrared radiation heating device; Low temperature furnace, such as air circulation of industrial electric furnace, furnace, etc. ; Oil, water and other chemical liquid, in the plating bath liquid heating device. Water distillation apparatus. Alkali and acid heating device. In the food industry, which is used to bake bread, cookies, cakes, water tunnel for electric device. Plastic products processing and forming, extrusion device and rubber mold vulcanization device. Medical and health * * equipment, such as * *, * *, etc. Electrical heating of vacuum leaching paint equipment, enameled wire drying device, etc. In daily life all kinds of household electric appliances, such as electric cooker, electric oven, electric rice cooker, electric frying pans, electric frying pan, water heater, electric iron, and other products.

the electric heating tube heating speed is controlled by what to

electric heating tube experts explain for you electric heating tube heating speed is controlled by what to do. It depends on the structure of the electric heating tube, the inverter can only change the frequency of the alternating current, thus changing the rotational speed of the motor, reach the purpose of changing the output power of the motor. And heating tube is not rotational, also cannot control heating speed. There are two simple way:

1. With diode half-wave rectifier, change the effective value of ac, achieve the goal of change heating power and heating speed; This method *, its advantage is circuit, simple in structure, convenient in operation.

2. Transformer, with a small transformer transformer, the advantage is more file regulation, defect is circuit structure is relatively complex, high production costs.
