Energy saving of film blowing machine:most of them use frequency converters.The way to save energy is to save the remaining energy consumption of the motor.For example,the actual power of the motor is 50Hz,but you actually only need 30Hz in production.Those excess energy consumption will be wasted.The frequency converter is to change the power output of the motor to achieve the effect of energy saving.
Energy saving of heating part:most of the energy saving of heating part adopts electromagnetic heater,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,which increases the utilization rate of heat energy.
2.Compared with resistance heating,the electromagnetic heater directly acts on the material pipe heating,reducing the heat loss of heat transfer.
3.Compared with resistance heating,the heating speed of electromagnetic heater is more than one quarter faster,which reduces the heating time.
4.Compared with resistance heating,the heating speed of electromagnetic heater is faster,the production efficiency is improved,and the motor is in a saturated state,which reduces the power loss casued bu high power and low demand.
The above four points are the reasons why the electromagnetic heater can save up to 30%-70% energy on the film blowing machine.
