2017-10-14 Throughput of a melt pump with simple input pressure control

By far the best way to get a stable throughput from an extruder is to use a melt pump on the output. In concept the melt pump is very simple. It uses a pair of closely meshed gears, placed in the main plastic stream. The teeth are filled at the input,leveled off by the housing, and then emptied at the meshing point. The device can be thought of as measuring cups on a wheel. The teeth are loaded at the input and emptied at the output. The important thing to note is that the gear pump is a positive displacement device. There is no channel open between input and output, as in a screw type pump. E

2017-09-28 The external gear pump choose

The external gear pump is a positive displacement (PD) type of pump generally used for the transfer and metering of liquids. The pump is so named because it has two gears that are side-by-side or external to each other. (This nomenclature differentiates it from an internal gear pump, which has one gear positioned inside the other.) The gear pump is a precision machine with extremely tight fits and tolerances, and is capable of working against high differential pressures. The working principle of
