PVC thermosensitive plastic extrusion melt pump gear pump

In the field of plastic processing, PVC (polyvinyl chloride) is widely used in the production of pipes, sheets, films and other products due to its excellent properties. However, the thermal sensitivity of PVC material makes the processing window narrow and extremely sensitive to temperature fluctuations, which can easily lead to decomposition, carbonization, and even coke formation due to local overheating, seriously affecting product quality and production line continuity. In response to the pain points in this industry, BATTE Machinery has launched a professional PVC melt gear pump solution with a deep understanding of material characteristics and profound technical accumulation.

By using the melt gear pump as a positive displacement conveying device, the functions of "pressure building" and "metering" are separated from the screw extruder, thus achieving revolutionary optimization of the PVC melt conveying process.

Optimized flow channel and gear design: The inlet adopts a horn shaped flow channel to ensure that the PVC melt enters the meshing area smoothly and stably, reducing shear heat generation and flow dead corners. The internal flow channel and gear parameters have been specially optimized to achieve low pressure loss and high uniformity in conveying.

Built in melt self-lubricating system: The unique lubrication channel design allows a small amount of melt to self lubricate key parts such as gear shaft sleeves. The lubricating medium is discharged together with the main material, without the need for an external oil filling circuit. This not only simplifies the structure, but also eliminates the pollution of PVC materials by external additives, especially suitable for PVC product production scenarios with high cleanliness requirements.

High precision gear clearance and volumetric structure: By strictly controlling the gear clearance and volumetric cavity design, the melt pump can accurately control the material conveying volume, eliminate extrusion instability caused by upstream processes such as uneven feeding and temperature fluctuations, and achieve high-precision continuous extrusion.
