Screw pumps geometry

The equations given in Fig. 6.5a and/or 6.5b can also be applied to an extruder section. In general, however, we do not know the power input to the shafts for an extruder section or, therefore, the specific energy input for this section. The pumping efficiency can be of use here it is determined in advance for the screw geometry in question (measurements taken with a model fluid are adequate, see Section 6.7) or determined by 3-dimensional calculations (as shown in Fig. 6.7). [Pg.112]

Table 6.3 summarizes the effects of screw geometry on pumping capability, degree of fill, mean residence time, and pressure build-up capability of the screw elements. Different types of screw elements should be used to design an optimum screw configuration for an application of interest. [Pg.287]
