Factors Affecting the Energy Consumption of Extruders
Heating rings are often used in the heating of plastic extruder equipment. Nowadays, electromagnetic heating coils have basically replaced traditional heating coils and have been widely used. Electromagnetic heating coil heating is a heating method that converts electrical energy into magnetic energy and induces the heated steel into magnetic energy. Fundamentally solve the problem of low efficiency through heat conduction methods such as electric heating plates and electric heating coils.
Normal operation of the extruder, that is, when the extruder is extruding normally, the heating ring has a certain energy consumption, and the temperature will fluctuate up and down. The energy consumption of the electromagnetic heating ring needs to be considered when the extruder is running normally. The factors are as follows:
1. Heating coil power
2. Process temperature during production
3. The ambient temperature of the extruder
4. The frictional heat inside the extruder (this is the most complicated, and it also has a great impact on the energy consumption of the heating ring. For some materials, the heating ring does not need to be heated, but has to keep cooling down; this is related to the speed of the extruder. , The state and structure of the screw and barrel, the performance of the production material, etc. are related)
5. The sensitivity and accuracy of the temperature control system.
The thermal efficiency of the special electromagnetic heating coil for the extruder is as high as 85% or more, which is more than electricity saving than the resistance heating under the same conditions, and the preheating time is shortened to save a lot of electricity, reducing production costs, reducing production costs, and improving product competition Has brought huge economic benefits to the enterprise
