The energy saving of the degradable film blowing machine can be divided into two parts: one is the power part and the other is the heating part. Energy saving in the power part: most of them use frequency converters. The energy-saving method is to save the remaining energy consumption of the motor, such as the actual power of the motor is 50Hz, but you actually only need 30Hz for production, and those excess energy consumption will be wasted. The frequency converter is to change the power output of the motor to achieve the effect of energy saving. Energy saving of heating part: most of the energy saving of heating part adopts electromagnetic heater, and the energy saving rate is about 30% - 70% of the old resistance coil.

Compared with resistance heating, the electromagnetic heater has an additional insulation layer, which increases the utilization rate of heat energy. Compared with resistance heating, the electromagnetic heater directly acts on the material pipe heating, reducing the heat loss of heat transfer. Compared with resistance heating, the heating speed of electromagnetic heater is more than one quarter faster, which reduces the heating time. Compared with resistance heating, the heating speed of electromagnetic heater is fast, the production efficiency is improved, and the motor is in a saturated state, which reduces the power loss caused by high power and low demand.
