Introduction of special melt pump for PVC
Batte’s research and development of PVC special melt pumps are specialized in conveying, pressurizing and metering polyvinyl chloride (PVC) high-viscosity polymers. PVC is a kind of heat-sensitive material, which is more sensitive to temperature changes. It is easy to cause carbonization, decomposition and even scorching of the material during the extrusion process. The inlet of the PVC series special melt pump adopts a horn-type flow channel, and the internal flow channel and the structure of the gear are optimized. The built-in melt self-lubricating, the lubricating material is discharged with the material. This structure is more suitable for the material characteristics of PVC.
PVC special melt pump structure
The PVC special pump is mainly composed of pump casing, driving gear, driven gear, sliding bearing, front and rear end plates, packing seal, etc.

Features of PVC melt pump
The melt discharge pump is a positive displacement conveying equipment. The high-precision gear gap and volumetric structure design make stable and balanced extrusion possible. It is used in chemical fiber, pelletizing, plastic film, sheet, plate, profile, Pipes, wires and cables, wire drawing, composite extrusion and other production lines have been widely used, and have achieved relatively good results:
1. It can realize stable extrusion, improve the dimensional accuracy of extruded products, and reduce the rejection rate. In the extrusion process, it is inevitable that the amount of material fed is uneven, the temperature fluctuations of the barrel and head, and the pulsation of the screw speed are unavoidable. The use of a melt gear pump can eliminate the feeding error of the feeding system, greatly reduce the fluctuation of upstream process transmission, quickly enter a stable working state, improve the dimensional accuracy of extruded products, and reduce the rejection rate.
2. Increase output, reduce energy consumption, achieve low temperature extrusion, and extend the life of the machine. Since the extruder is equipped with a polymer melt pump, the decompression function of the extruder is transferred to the gear pump. The extruder can work at low pressure and low temperature, the leakage flow is greatly reduced, and the output is increased. The gear pump can build up the head pressure more effectively than the extruder, and can reduce the back pressure of the extruder, reduce the axial force of the screw, and extend the service life.
3. With linear extrusion characteristics, it is convenient for upstream and downstream equipment to coordinate work. Due to the low leakage flow of the gear pump, the delivery capacity of the pump is basically linear with the speed. After the speed of the gear pump is changed, its flow can be accurately known. Since the working speed of the upstream and downstream equipment and the gear pump can be determined, the gear pump can be used The pressure, temperature and other information collected at the inlet and outlet can realize online monitoring and feedback control of the entire extrusion process.
