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.
Energy saving in the power part: most of them use frequency converters. The energy saving method is to save the excess energy consumption of the motor. For example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production. Wasted, the frequency converter is 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 the use of electromagnetic heaters to save energy, 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 additional layer of insulation layer, which increases the utilization rate of heat energy.
2. Compared with resistance heating, the electromagnetic heater directly acts on the heating of the material tube, which reduces the heat loss of heat transfer.
3. Compared with resistance heating, the heating speed of the 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 fast, 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.
