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: most of them use frequency converters. The energy saving method is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, but you actually only need 30Hz to produce. Those extra energy consumption is wasted. The frequency converter is to change the power output of the motor to achieve the energy saving effect.
Energy saving in heating part: most of the energy saving in heating part is energy saving by electromagnetic device, and the energy saving rate is about 30% - 70% of the old resistance coil.
1. Compared with resistance heating, the electromagnetic heater has an additional insulation layer, and the heat utilization rate is increased.
2. Compared with resistance heating, the electromagnetic heater directly acts on the heating of the material pipe, reducing the heat loss of heat transfer.
3. Compared with resistance heating, the heating speed of electromagnetic heater is more than one quarter faster, which reduces the heating time.
4. Compared with resistance heating, the heating speed of the electromagnetic heater is faster, and the production efficiency is improved. The motor is saturated, which reduces the power loss caused by high power and low demand.
The above four points are the reasons why feiru electromagnetic heater can save 30% - 70% energy on the film blowing machine.
