Do you know about melt pumps for sheet film extrusion?
Extrusion melt pumps are widely used in the fields of sheet, blown and salivated films, spraying, textiles (fibers and nonwovens), EVA, compounding, pelletizing, and biodegradable materials. Under constant pressure, melt pumps have a lower shear stress design, which reduces the energy consumption of the extruder, lowers the working temperature and increases the output rate.
Extruder melt pump structure is mainly composed of by the pump casing, front and rear side cover, gear shaft, sliding bearing and shaft seal. It has the following four main advantages:
1, very small pressure flow pulsation, can realize the flow of linear output, suitable for precision extrusion system;
2、It adopts different structure and material configurations for different working conditions to better meet the user's individual needs;
3, can be applied to high temperature ( 350 ° C ), high pressure ( 40MPa ), high viscosity ( 40,000Paos ) conditions;
4、Precise structure, high accuracy and long life.
For standard type extrusion melt pumps, the pump casing and gears are made of nitrided steel, and the bearings are made of tool steel, which have good abrasion resistance, high toughness, high cost performance, and are suitable for most of the working conditions with low abrasion. For high abrasion-resistant extrusion melt pumps, the pump casing is made of nitrided steel, and the gears and bearings are made of tool steel, which has high strength and high abrasion resistance and is suitable for abrasive wear conditions. For high corrosion-resistant melt pumps, the pump casing is made of stainless steel, and the gears and bushings are made of tool steel, which have high corrosion resistance and are suitable for highly corrosive working conditions.
