Batte melt pump in the extrusion of wood-plastic production line
WPC profile production line is mainly used PVC + wood flour, production kicks moldings, door line, Door line, a hundred blades, picture frames, frames, door frames, door pockets, window cover, stand in vain, stair railings, decorative buckle, furniture, timber and other profile extrusion. Production line using the original wood technology and formula, according to different profiles section, different uses, different proportion of product design, use different specifications of wood-plastic twin-screw extruder with a melt pump Bart special, unique tractor technology, steady work, good reliability, great traction. Increase the use of special vacuum stereotypes swirl cooling system, to facilitate cooling stereotypes, in order to meet the characteristics of WPC production needs. Sawing device profiles traction to keep pace, design reasonable, stable operation can be automatically cut to length and equipped with dust recovery.
Batte melt pump characteristics:
1. To achieve stable extrusion, extrusion products to improve the dimensional accuracy and reduce scrap rates. In the extrusion process, uneven material feeding amount of fluctuation barrel and die temperature, screw speed of pulsation phenomenon is difficult to avoid. A melt gear pump feeding system can eliminate feed errors can be greatly reduced volatility upstream process passed quickly into the stable working conditions, improve the dimensional accuracy of the extruded product, reduce scrap rates.
2. increase production, reduce energy consumption and achieve low-temperature extrusion, extend the life of the machine. Since the installation of the extruder the polymer melt pump, the pressure reducing function is transferred to the extruder gear pump is completed, the extruder can operate at low pressure and temperature state, the leakage flow is greatly reduced, the yield is improved. Gear pump more effectively build than the extruder head pressure, and reduce back-pressure extruder screw axial force to bear down and prolong life.
3. With the linear extrusion characteristics, easy on the downstream device coordination. Since the gear pump leak less flow, transmission capacity and speed of the pump substantially linear relationship, after the gear pump speed changes, the traffic can know exactly, due to be determined, downstream equipment and gear pump operating speed synchronized by a gear pump inlet pressure at the outlet collected, temperature and other information, the entire extrusion process to achieve full-line monitoring and feedback control.
The melt pump is mainly used for high temperature and high viscosity of the polymer melt conveying, pressurization, and Measurement. Its main function is to melt from the extruder temperature pressurization, regulator, maintaining accurate and stable flow of melt into the extrusion head. Today, the melt gear pumps have been widely used in chemical fiber, granulation, plastic film, sheet, plate, extrusions, pipes, wire and cable, drawing, composite extrusion production line, processable polymer materials almost covers most materials, such as: PE, PC, PP, PVC, HIPS, PS, PA, TPUR, fluoropolymers, polysulfones, polyesters, thermoplastic elastomers, rubbers, and thermal adhesives and the like.
