Energy-saving transformation of the power part of the film blowing machine: 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 80Hz, but you actually only need 50Hz for production. Those extra Energy consumption is wasted. The frequency converter changes the power output of the motor to achieve energy saving. The energy saving of the film blowing machine can be divided into two parts: one is the power part and the other is the heating part. 1. Energy saving in the power part: Frequency converters are mostly used. 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 actually only need 30Hz in production to produce. Those excess energy consumption It's all wasted. The inverter changes the power output of the motor to achieve energy saving. 2. Energy saving in the heating part: Most of the energy saving in the heating part is the use of electromagnetic heaters. The energy saving rate is about 30%-70% of the old-fashioned resistance coil. 1. Compared with resistance heating, electromagnetic heaters have an extra layer of insulation, which increases the utilization rate of heat energy. 2. Compared with resistance heating, the electromagnetic heater directly acts on the material tube to heat, reducing heat transfer heat energy loss. 3. Compared with resistance heating, the heating speed of electromagnetic heater is more than a quarter faster, reducing the heating time. 4. Compared with resistance heating, the heating speed of electromagnetic heaters is faster, which improves production efficiency and puts the motor in a saturated state, reducing the power loss caused by high power and low demand. The above four points are the reasons why Feiru electromagnetic heater can save up to 30%-70% energy on film blowing machines. Film blowing machine frequency conversion application process principle: Add dry polyethylene particles into the lower hopper and enter the screw from the hopper by the weight of the particles themselves. When the pellets come into contact with the thread bevel, the rotating bevel faces the plastic and generates a thrust perpendicular to the bevel face, pushing the plastic particles away. Pushing forward, during the pushing process, due to the friction between the plastic and the screw, the plastic and the barrel, the collision and friction between the particles, and also due to the external heating of the barrel, it gradually melts. The molten plastic is filtered by the machine head to remove impurities and comes out of the die mouth. It is cooled by the air ring and blown through the herringbone plate, the traction roller, and the finished film is rolled into a cylinder.
