The energy saving of the film blowing machine can be divided into two parts: one is the power part and the other is the heating part.
 
Energy saving in power part: Frequency converters are mostly used. The energy saving method is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, while you actually only need 30Hz to produce in production. The excess energy consumption is wasted. Frequency converters are to change the power output of the motor to achieve the effect of energy saving.
 
Energy saving in the heating part: Most of the energy saving in the heating part is by electromagnetic devices, and the energy saving rate is about 30%-70% of that of the old resistance ring.
 
1. Compared with resistance heating, electromagnetic heater has an additional thermal insulation layer, thus increasing the utilization rate of heat energy.
 
2. Compared with resistance heating, the electromagnetic heater directly acts on the material pipe to heat, thus reducing the loss of heat transfer and heat energy.
 
3. Compared with resistance heating, the heating speed of electromagnetic heater is more than a quarter faster, reducing the heating time.
 
4. Compared with resistance heating, the electromagnetic heater has faster heating speed and higher production efficiency, leaving the motor in a saturated state, reducing the power loss caused by high power and low demand.
