The energy saving of the blow molding machine can be divided into two parts: one is the power part, and the other is the heating part.
The energy saving of the 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 only need 30Hz in production to suffice. The excess energy consumption is in vain. Wasted, the inverter is to change the power output of the motor to achieve the effect of energy saving.
Energy saving in heating part: Most of the energy saving in heating part adopts electromagnetic heater energy saving, 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 energy utilization rate increases.
2. Compared with resistance heating, the electromagnetic heater directly acts on the material tube heating, reducing the heat transfer heat energy loss.
3. Compared with resistance heating, the heating speed of the electromagnetic heater is more than a quarter faster, reducing 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 it, and the power loss caused by high power and low demand.
