batte melt pump

High temperature 0.4CC type plastic extrusion melt pump

Melt pump is mainly used for high temperature and high viscosity polymer melt conveying, supercharging and metering. Its main function is to pressurize and stabilize the high-temperature melt from the extruder to keep the melt flow accurate and stable into the extruder head. Nowadays, melt gear pump has been widely used in chemical fiber, granulation, plastic film, sheet, sheet, profiles, pipes, wires and cables, wire drawing, composite extrusion and other production lines. Processing materials almost cover most of the polymer materials, such as: PE, PC, PP, PVC, HIPS, PS, PA, TPUR, fluoropolymer, etc. Polysulfone, polyester, thermoplastic elastomer, rubber and thermal adhesives. batte melt pump is a kind of positive displacement conveying equipment. The design of high precision gear clearance and volumetric structure makes it possible to extrude stably and equally. It is widely used in chemical fiber, granulation, plastic film, sheet, sheet, profile, pipe, wire and cable, wire drawing, compound extrusion and so on. Good result:

1., it can achieve stable extrusion, improve the dimensional accuracy of extruded products, and reduce the reject rate. In the process of extrusion, it is difficult to avoid such phenomena as uneven material loading, fluctuation of barrel and head temperature, and pulsation of screw speed. The use of melt gear pump can eliminate the feeding error of the feeding system, greatly reduce the upstream process transfer fluctuation, quickly enter a stable working state, improve the dimensional accuracy of extruded products, reduce scrap rate.

2. increase production, reduce energy consumption, achieve low temperature extrusion and prolong machine life. Because the extruder is equipped with polymer melt pump, the pressure reducing function of the extruder is transferred to the gear pump. The extruder can work at low pressure and low temperature. The leakage flow is greatly reduced and the output is increased. Gear pump is easier and more effective than the extruder to establish the head pressure, and can reduce the back pressure of the extruder, so that the axial force on the screw is reduced, and the service life is prolonged.
