Increasing extrusion production of circular arc gear pump in polymer material fo

When the pressure of an extruder increases, the reverse flow rate and leakage flow rate also increase, resulting in a decrease in the overall flow rate. At the same time, the power consumed by the screw to push the material forward increases, the shear force increases, and the material temperature rises, ultimately leading to material degradation, which is unfavorable for the forming and processing of thermosensitive materials. After installing the circular arc gear pump, there is no need for too much pressure inside the extruder because the gear pump can act as a booster. Due to the circular arc gear pump; It can complete the pressure stabilization and pressurization functions of the extruder metering section, so the extruder screw only needs to complete continuous conveying, melting, and mixing, without considering metering extrusion. After the pressure inside the extruder decreases, the reverse flow rate and leakage flow rate also decrease. The screw can rotate at high speed under low pressure, resulting in a decrease in the shear force on the material, a decrease in melting temperature, an increase in extrusion volume, a decrease in power consumption, and an increase in the range of products produced. In addition, due to the metering and boosting functions of the circular arc pump, installing a gear pump on the extruder can shorten the metering section of the screw, increase the mixing section, and increase the screw groove. The performance obtained by the combination of extruder and gear pump makes this equipment applicable. In fact, this equipment can process different plastics and produce products, especially when processing difficult materials and producing products, it can play its own role; Specialty” For example:
