How To Control The Heating Speed Of The Flange Tubular Heater？
This depends on the structure of the heater, the inverter can only change the AC frequency, thereby changing the motor's rotation speed, to achieve the purpose of changing the motor's output power. Moreover, the heater does not rotate, and the frequency conversion cannot control the heating speed. The pole tube half-wave rectification is used to change the effective value of the alternating current to achieve the purpose of changing the heating power and heating speed; this method is the most used, the circuit structure is simple, and the operation is convenient.
Using a small transformer to transform, the advantage is that it can be adjusted in multiple stages, but the disadvantage is that the circuit structure is more complicated and the manufacturing cost is high. The energy saving effect is significant, and almost 100% of the electric energy is transferred to the heating medium. The heating tube is made of stainless steel as a whole, except for the connecting flange, all other parts are made of stainless steel. Supplemented by the electric heating tube to thicken the polyurethane foam insulation layer, reduce the temperature of the stainless steel inner tank and the stainless steel shell, maintain the hot water temperature and save electricity.
