The energy saving of the extrusion blow molding machine can be divided into two parts: one is the power part and the other is the heating part.
Power part energy saving: most of the use of inverter, energy saving is to save the residual energy of the motor, such as the actual power of the motor is 50Hz, and you actually only need 30Hz in the production is enough to produce, the excess energy consumption is wasted, the inverter is to change the power output of the motor to achieve energy-saving effect. Heating part energy saving: heating part energy saving is mostly the use of electromagnetic heater energy saving, energy saving rate is about 30%-70% of the old resistor ring.
1. Compared with resistance heating, the electromagnetic heater has more than one layer of insulation layer, and the heat energy utilization rate is increased.
2. Compared with resistance heating, the electromagnetic heater directly acts on the material pipe heating, reducing the heat transfer 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 fast, the production efficiency is improved, so that the motor is in a saturated state, so that it reduces the power loss caused by high power and low demand. The above four points are why the electromagnetic heater can save energy up to 30%-70% on the blow molding machine.
