The energy saving of the plastic granulator can be divided into two parts: one is the power part and the other is the heating part.
Energy saving in the power part: The main use of frequency converters is to save the residual energy of the motor. For example, the actual power of the motor is 50Hz, but you only need 30Hz in production to be enough for production, and those excess must be wasted. , Inverter is to change the power output of the motor to achieve energy saving effect.
Energy saving in heating part: The energy saving in heating part is mainly the use of electromagnetic heaters. The energy saving rate is about 30%-70% of the old resistance coil.
1. Resistance heating, the electromagnetic heater has an extra layer of insulation, which increases the utilization rate of heat energy.
2. Resistance heating, electromagnetic heater directly acts on the material tube to heat, reducing the heat loss of heat transfer.
3. With reference to resistance heating, the heating speed of the electromagnetic heater is faster than a quarter, which reduces the heating time.
4. With reference to resistance heating, the heating speed of the electromagnetic heater is fast, the production efficiency is improved, and the motor is in a saturated state, thereby reducing the power loss caused by high power and low demand.
The above four points are the electromagnetic heater, why can save energy up to 30%-70% on the plastic granulator.
