Melt pump is a positive displacement conveyor equipment, high-precision gear gap and volume structure design, so that a stable and balanced extrusion possible, in chemical fiber, granulation, plastic film, sheet, sheet, profiles, pipe, wire Cable, wire drawing, composite extrusion and other production lines have been widely used, and achieved good results: 1. To achieve a stable extrusion, extrusion products to improve dimensional accuracy, reduce scrap rate. In the extrusion process, the uneven feeding of materials, barrel and head temperature fluctuations, pulsating speed and other phenomena is difficult to avoid. The use of melt gear pump can eliminate feeding system feeding error, can greatly reduce the upstream process of transmission fluctuations, rapid access to stable working conditions, improve the dimensional accuracy of extruded products, reduce scrap rate. 2. To increase production, reduce energy consumption, low temperature extrusion, 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, and the extruder can work under the condition of low pressure and low temperature, the leakage flow is greatly reduced, and the output is increased. Gear pumps create head pressure more effectively than extruders and reduce backpressure on the extruder, allowing the screw to withstand the axial forces and prolonging service life. 3. With linear extrusion characteristics, to facilitate the coordination of downstream equipment. As the gear pump leakage less, the pump capacity and speed of the basic linear relationship between the gear pump speed changes, the flow can know exactly, because it can determine the upstream and downstream equipment and gear pump synchronization work speed, the use of gear pump Entrance and exit of the collection of pressure, temperature and other information to achieve the entire extrusion process online monitoring and feedback control.
Macor Ceramic Plunger
By using the mechanical and thermal properties of glass ceramics such as high temperature resistance, thermal shock resistance, thermal expansion and other mechanical properties, it is possible to manufacture a variety of materials that meet the mechanical requirements. Using mica's machinability and orientation, it is possible to produce high-strength and machinable glass ceramics. As a mechanical mechanics material, glass ceramics can be widely used in pistons, rotating blades and cookware, and can also be used as structural materials for aircraft, rockets, and artificial satellites.
