Supply high temperature BOPA biaxially oriented film melt pump gear melt pump

Supply high temperature BOPA biaxially oriented film melt pump gear melt pump Haike melt pump is a kind of positive displacement conveying equipment, high precision gear clearance and volumetric structure design, making stable and balanced extrusion possible, in chemical fiber, Granulation, plastic film, sheet, sheet, profile, pipe, wire and cable, wire drawing, composite extrusion and other production lines have been widely used, and achieved good results:

1. It can achieve stable extrusion, improve the dimensional accuracy of extruded products and reduce the scrap rate. During the extrusion process, uneven material feeding, fluctuations in barrel and head temperature, and pulsation of screw speed are difficult to avoid. The use of the melt gear pump can eliminate the feeding error of the feeding system, can greatly reduce the fluctuation of the upstream process transfer, quickly enter a stable working state, improve the dimensional accuracy of the extruded product, and reduce the scrap rate.

2. Increase production, reduce energy consumption, achieve low temperature extrusion, and 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 low pressure and low temperature conditions, the leakage flow is greatly reduced, and the output is improved. The gear pump can more easily and effectively establish the head pressure than the extruder, and can reduce the back pressure of the extruder, so that the axial force of the screw is reduced and the service life is prolonged.

3. It has linear extrusion characteristics, which facilitates the coordination of upstream and downstream equipment. Since the gear pump has less leakage flow, the pump's conveying capacity is basically linear with the speed. After the gear pump speed is changed, the flow rate can be known exactly. Since the working speed of the upstream and downstream equipment and the gear pump can be determined, the gear pump can be used. The information such as pressure and temperature collected at the entrance and exit will realize online monitoring and feedback control throughout the entire extrusion process.
