Energy-saving part of the power: Most inverters are used. The energy-saving method is to save the remaining energy of the motor. For example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production to produce enough. The extra energy consumption is in vain. Wasted, the frequency converter is to change the power output of the motor to save energy.
Heating part of the energy: Most of the heating part of the energy-saving is the use of electromagnetic heaters, energy saving rate is about 30% -70% of the old resistor ring.
1. Compared with the resistance heating, the electromagnetic heater has a layer of insulation and the thermal energy utilization increases.
2. Compared with the resistance heating, the electromagnetic heater directly acts on the heating of the material tube, which reduces the loss of heat transfer heat energy.
3. Compared with resistance heating, the heating rate of the electromagnetic heater is more than a quarter faster, reducing the heating time.
4. Compared with the resistance heating, the heating speed of the electromagnetic heater is fast, and the production efficiency is improved, so that the motor is in saturation, which reduces the power loss caused by high power and low demand.
