Spinning gear pump, the melt pump is a positive displacement conveyor equipment, high-precision gear clearance and volume structure design, so that a stable and balanced extrusion possible, in the chemical fiber, granulation, plastic film, sheet, Plate, profile, pipe, wire and cable, 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 to eliminate the feeding system feeding. Errors, can greatly reduce the fluctuations in the upstream process delivery, rapid access to a stable working condition, 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.
Other Constructions SS Wire Rope
Wire rope quality judgment:
1. Specific gravity. The diameter of the wire rope is the same, the heavier the specific gravity, the better the quality of the wire rope.
2. Steel wire rope core. The stronger the core of the wire rope, the heavier the specific gravity, the better the support for the outer strand of the wire rope, and the better the quality of the wire rope.
3. Materials. The material is the steel grade and strength. The higher the steel grade, the better the quality of the wire rope with higher strength.
4. After the rope is cut, the slightly loose quality is good, and the quality of the wire rope with a relatively long lay length is better than that with a short lay length.
5. The anti-corrosion ability of 316 Stainless Steel Wire Rope is stronger than that of 306 stainless steel wire rope, and the anti-corrosion ability of 306 is stronger than that of hot-dip galvanized steel wire rope. The quality of hot-dip galvanized steel wire rope is better than that of electro-galvanized steel wire rope; the quality of nylon plastic-Coated Steel Wire Rope is stronger than that of PE plastic-coated steel wire rope.
