Plastic pipe specific melt pump

一、Precision Metering and Stable Extrusion

High-Precision Flow Control: The dedicated melt pump for pipe materials employs a volumetric design, where the volume of melt delivered per revolution of its gears is relatively fixed. By precisely controlling the gear speed, high-precision flow control can be achieved, ensuring dimensional accuracy of the extruded pipe and reducing waste rates.

Effective Isolation of Fluctuations: During the extrusion process, phenomena such as uneven material feeding, temperature fluctuations in the barrel and die head, and screw speed pulsations are difficult to avoid. The melt pump effectively dampens fluctuations transmitted from upstream processes, quickly entering a stable operating state, resulting in more stable and uniform dimensions of the extruded pipe.

二、Increased Production Efficiency and Quality

Boosted Output: With the use of a melt pump, the extruder can operate at lower pressures and temperatures, significantly reducing leakage flow and the axial force on the screw. This allows for high-speed and efficient extrusion of materials, increasing the production volume of pipes.

Improved Quality: By adjusting the extruder's backpressure, the residence time of the melt within the screw barrel is reduced, stabilizing the plasticization process and lowering the melting temperature. This enhances the quality of the pipes, such as smoother surfaces and more uniform internal structures.

三、Extended Equipment Lifespan

Reduced Component Wear: With the installation of a melt pump on the extruder, its pressure reduction function is transferred to the melt pump, lowering the pressure within the extruder barrel. This significantly reduces wear between the screw and barrel, as well as the load on the thrust bearings of the gearbox, thereby extending the lifespan of the extruder.

四、Excellent Material Adaptability

Compatibility with Various Polymeric Materials: The processable materials cover almost all polymeric materials, such as PE, PC, PP, PVC, HIPS, PS, PA, TPU, fluoropolymers, polysulfones, polyesters, thermoplastic elastomers, rubbers, and hot-melt adhesives, meeting the needs of different pipe production.

Suitable for Extrusion of Special Materials: Some dedicated melt pumps for pipe materials adopt special designs and materials, such as improved gear parameters, specialty materials, and wear-resistant coatings, making them more suitable for the extrusion of transparent products like PC and PMMA, as well as PVC thermosensitive materials. This improves production efficiency while ensuring product quality.

五、Linear Extrusion Characteristics and Online Monitoring

Facilitated Coordination: The delivery capacity of the melt pump is basically linearly related to its speed, with minimal leakage flow. Therefore, by knowing its speed, one can accurately determine changes in flow rate, allowing for synchronization of upstream and downstream equipment with the gear pump, facilitating coordination between them.

Real-Time Monitoring: By utilizing information such as pressure and temperature collected at the inlet and outlet of the melt pump, real-time online monitoring and feedback control of the entire extrusion process can be achieved, promptly identifying and resolving issues during production, further enhancing production stability and product quality.

六、Reliable Sealing and Self-Lubricating System

Prevention of Glue Leakage: Using filling seals and mechanical spiral seals, the leakage of glue is effectively prevented, ensuring production continuity and environmental cleanliness.

Self-Lubricating Function: The pump self-lubricates using the conveyed plastic melt, eliminating the need for conventional lubricants or greases, avoiding contamination of the material and reducing maintenance costs.

七、Optimized Structural Design

Reduced Material Residence Time: The pump body features high surface smoothness, and the self-lubricating system and inlet/outlet flow channels have been optimized with linear flow channel design, effectively reducing the residence time of material within the pump, achieving optimal plasticization and stable, balanced extrusion.

Versatile Installation Methods: Suitable installation methods can be provided based on different customer site conditions, such as horizontal or vertical arrangement of the pump's input shaft, adding flexibility and practicality.
