About energy saving of film blowing machine
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 the power part: Most of the inverters are used. The energy saving method is to save the residual energy of the motor. For example, the actual power of the motor is 50Hz, and you actually only need 30Hz in the production to be enough for production, and the excess energy consumption is in vain If it is wasted, the inverter is to change the power output of the motor to achieve the effect of energy saving.
Energy-saving heating part: Most of the energy-saving heating part is the use of electromagnetic heaters, and the energy-saving rate is about 30%-70% of the old-fashioned resistance coil.
1. Compared with resistance heating, the electromagnetic heater has an extra layer of insulation, which increases the utilization rate of heat energy.
2. Compared with resistance heating, the electromagnetic heater directly acts on the material tube to heat, which reduces the heat loss of heat transfer.
3. Compared with resistance heating, the heating speed of electromagnetic heater is more than a quarter faster, which reduces the heating time.
4. Compared with resistance heating, the heating speed of the electromagnetic heater is faster, 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.
