Как да изберете мощността на електрическата топлинна тръба?

Voltage: in the design voltage range of electric heating tube, the voltage will affect the power level. Therefore, when designing power, the normal voltage should be determined first. Common voltages are 220V and 380V. Take 380V as an example. If the power is 1000W, the heating power will be lower than 1000W when the voltage is less than 380V. When the voltage is higher than 380V, the heating power will be greater than 1000W, but it is easy to cause excessive load and damage to the heating tube. 2. Heating environment: the heating environment of electric heating tube can be divided into dry heating and heating liquid. 1. Dry burning: 1) conventional dry Изгаряне: Дизайнът на нормалната мощност на отопление на сухо изгаряне е 1000W мощност, съответстваща на дължината на един метър . 2) вентилатор: В случай на вентилатор, мощността от 1500W може да бъде постигната с дължината на един метър; In the case of no fan circulation, the total length (meters) and power (KW) is 1:1. 2. Heating liquid: heating liquid can be divided into heating water and oil. 1) power design of conventional heating liquid: the relationship between the total length (meter) of electric heating tube and the power (KW) is 1:3, that is, the total length of one meter can be 3kW . 2) отоплителна вода: Обикновено отоплителната вода може да се извърши до 3000W и до 4000W . 3) отоплително масло: мощността на отоплителното масло е проектирана да бъде 2500W с обща дължина от един метър и 3000W в максимално . 3. друго медийно отопление: отопление на други специали substances. The designed power is much lower than that of conventional heating environment. 3. Determination of total power: the total power of the electric heat pipe shall be determined according to the specific parameters of heating liquid or air. 1. Determine the parameters to be provided for the total power of heating liquid: the total volume of liquid, the total mass of liquid, the normal temperature of liquid, the temperature difference to be heated, the time requirement for heating, etc. 2. Determine the parameters needed for the total power of dry burning: heating space, conventional room temperature, heating temperature difference, heating time, etc. 3. In addition, factors such as tightness, heat preservation, internal material mobility and internal heat dissipation in the heating space will also have an impact on the total power required.
