Advantages of melt gear pump in screw extrusion system
In the plastic extrusion system, before using the melt gear pump, try the insufficient materialization caused by the unstable transportation of the screw extruder; In the melting section, the softening point of the material is unstable or the solid bed is broken, the motor load pulsation and uneven feeding lead to the screw extrusion fluctuation, which affects the quality of the finished product, such as uneven thickness and low precision. What are the advantages of using melt gear pump in screw extrusion system?
The addition of melt gear pump in extruder isolates the fluctuation produced by the extrusion screw from the machine head and downstream equipment, thus greatly reducing the fluctuation in the upstream and stabilizing the pressure; In an ideal state, there is no material sliding in the process of conveying materials by the melt gear pump, that is, it has a constant conveying volume. Therefore, no matter how the pressure at the inlet of the plastic extrusion melt pump changes and how big the flow fluctuation is, as long as the materials entering the melt gear pump can fill the slots, the melt gear pump can convey materials to the machine head with stable pressure and flow. The application of melt gear pump can effectively reduce the scrap rate and improve the quality of products; Extend the service life of screw extruder, reduce the production cost of extrusion system, and improve the overall economic benefits. The application of melt gear pump in screw extrusion system mainly reflects four advantages:
1. Stable output pressure;
2. Improve product quality;
3. Increase extrusion yield;
4. Reduce unit energy consumption.
