PP-R pipe melt pump
Introduction to PE Pipe Melt Gear Pump
During the extrusion process of high-temperature PP-R pipe melt pumps and PE pipe melt pumps, it is difficult to avoid phenomena such as uneven material feeding, fluctuations in barrel and head temperatures, and pulsations in screw speed. The use of a melt gear pump can eliminate feeding errors in the feeding system, significantly reduce fluctuations in upstream process transmission, quickly enter a stable working state, improve the dimensional accuracy of extruded products, and reduce scrap rates.
The main characteristics of the melt gear pump for pipe extrusion:
1. Can be applied to high temperature (350 ℃), high pressure (35MPa), high viscosity (20000Pas) working conditions;
2. Optimized channel design to avoid dead corners within the channel, reduce material residue, and improve product quality.
3. Improved gear parameter design ensures more stable output pressure and lower pulsation rate, making it suitable for precision extrusion.
4. Adopting high-temperature alloy steel, it has good wear resistance and long service life.
5. Adopting different sealing methods, suitable for a wide range of viscosity.
6. Suitable installation methods can be provided according to different on-site situations of customers, making them more flexible and practical.
