2025-08-07 Plastic pipe extruder melt pump
Pipe extruder melt pump is a high temperature and high viscosity polymer melt conveying, pressurizing and metering equipment specially designed for pipe production line, its core functions, technical advantages and typical application scenarios are as follows: I. Core function and working principle Positive displacement conveying Through gear meshing to form a closed volume chamber, the melt is forced to be pressed and sent to the outlet, and the flow rate is strictly proportional to the pump speed to ensure conveying stability. For example, the Bart ZB-C series adopts a high-precision gear cl
2025-08-01 Do you know about melt pump gears?
The core function of melt pump gears Melt pump gears are the core transmission components of melt pumps, responsible for converting motor power into high-precision, stable melt delivery power. Their special tooth profile design (such as involute or arc teeth) ensures continuous extrusion of melt under high pressure (typically 1050 MPa) with a pulsation rate below 1%, preventing polymer degradation. The gear material is typically nitrided steel or tool steel (such as 38CrMoAlA), with a surface hardness of HRC60 or higher to resist melt corrosion and mechanical wear. Precision Fit and Flow Contr
2025-07-19 What determines the rotational speed of a melt gear pump?
Polymer melt gear pumps belong to the positive displacement pump, the flow rate and rotational speed is nearly linear proportional relationship, the choice of pump speed determines the melt gear pump specifications, is an important selection parameters. The main factors that determine the rotational speed of the melt gear pump are: 1, the viscosity of the material, the higher the viscosity of the material, the lower the speed. High viscosity melt needs more driving force to push, if the speed is too high, the motor may be overloaded, and will increase the wear and tear of gears and pump body.
