Melt pump is a high temperature, high viscosity polymer melt conveying core equipment, precise control of displacement, pressure and temperature, widely used in plastics, chemical fiber and other industries, specifications from 0.05cc to 30,000cc, the outlet pressure of up to 50MPa, the working temperature up to 400 ℃, to ensure efficient and stable industrial production.
First, the application field
Polymer Melt Pump (English name: Melt Pump), is a kind of power equipment used for high temperature, high viscosity polymer melt transportation. It is mainly used for high-temperature, high-viscosity polymer melt conveying, pressurization, metering, in plastics, resins, rubber, chemical fiber products are widely used in extrusion molding, such as pelleting, film, tubing, plates, sheets, synthetic fibers, optical fibers, medical plastic catheters and other industries.
Second, the specifications
melt pumps of various specifications, from small to large specifications including but not limited to 0.05cc, 0.08cc, 0.1cc, 0.5cc, 1cc, 2cc, 5cc, 10cc, 20cc, 31.5cc, 50cc, 100cc, 150cc, 200cc, 315cc, 500cc, 800cc, 1200cc, 2500cc, 3200cc, 4000cc, 6100cc, 8000cc, 8500cc, 12000cc, 30000cc and so on. In fact, the specifications of melt pumps may vary according to different manufacturers, applications, conditions of use and other factors.
Third, the displacement and conveying capacity
Displacement is an important factor in determining the conveying capacity of the melt pump. Melt pump is a positive displacement conveying device, its flow and pump speed is strictly proportional to the relationship. Therefore, in the case of a certain displacement, control of the pump speed is essential to regulate the conveying capacity. Excessive speed may lead to melt decomposition due to high shear, so it is necessary to fully consider the impact of speed on the conveying capacity in the design.
Fourth, the pressure range
The working pressure of the melt pump is usually expressed in three parameters: inlet pressure, outlet pressure and differential pressure. Ordinary melt pump inlet pressure of less than 10MPa, the export pressure of less than 35MPa, the differential pressure of up to 25MPa. For pressure-resistant high melt pumps, the export pressure of up to 50MPa or even higher.
Fifth. Temperature range
The working temperature range of the melt pump is wide to adapt to the processing needs of different materials. Generally speaking, the working temperature of the melt pump can be up to about 400 ℃, the cleaning temperature can also reach the corresponding high temperature range. At the same time, the melt pump adopts electric heating or thermal medium heating system, which can precisely control the melt temperature to meet the processing requirements of different materials.
In addition, the melt pump also has linear output characteristics, stabilized pressure boosting characteristics and low energy efficiency and high volumetric efficiency. These features make melt pumps have a wide range of application prospects and important value in industrial production.
