Features of Extruder gear pump
◆ The steady export pressure--plastic melt pump can reduce the extruder output instability and pressure fluctuation caused by the extrusion machine parameters.
◆ Improve the product quality--extruder melt pump can minimize the dimensional tolerance of the extruded product and reduce the waste and scrape rate. Common extruder can also produce high precision products.
◆ Improve the output--melt pump lower the pressure requirements for the screw, change the voltage buildup way, from “screw to die-head” to “melt pump to die-head”. With the characteristic of high speed extrusion and high efficiency, the production line can adjust the extruder back pressure, reduce the staying time of melt within the screw tubes. And it aslo can make the plasticizing process stable, reduce the melting temperature, improve the output and quality.
◆ Lower energy consumption unit--some data also suggests that combine the co-rotating twin-screw extruder and plastic melt pump into mixing extruding production line, its mixing quality and output can be large increased than separate twin-screw granulator. The energy consumption can reduce about 25% generally.
◆ Prolong service life--extruder melt pump can reduce the extruder screw cylinder pressure if equipped with the melt pump, it also reduces wear between screw and screw tubes to a minimum and reduce the load of thrust bearing in gear case, accordingly prolong the production line service life. And the overflow of material in production process caused by xtruder venting can be readily solved.
