feed pressure

[′fēd ‚presh·ər]

(mechanical engineering)

Total weight or pressure, expressed in pounds or tons, applied to the drilling stem to make the drill bit cut and penetrate the geologic, rock, or ore formation.

Figs 4 and 5 show that within the pressure range, pure PSU membrane presented a decreasing trend of permeance with increasing feed pressure. Here in the Fig, the CO2 and CH4 permeance decreased from 7.40+-0.12 to 3.87+-0.2 GPU and 1.05+-0.05 to 0.34+-0.1 GPU with an increase in the pressure from 2 to 10 bar for pure PSU membrane.

This company has introduced a robust new series of ID grippers with an 8-85mm diameter range and high holding force that can be adjusted to individual workpieces via feed pressure. Color-coded to correspond with clamping positions for pushed and drawn parts and featuring strong elastomer bellows made of EPDM or silicone, the latter of which is FDA approved for direct contact with food, the new single-acting, pneumatically operated expansion grippers gently grip the inner contours of workpieces without leaving any marks, providing an effective alternative to suction cups and sprue grippers for parts with holes or recesses.

The system requires a minimum feed pressure of 110 psi and can operate at pressures up to 140 psi.

The reason to cool the screw this way is to prevent polymer from sticking to its surface until some feed pressure is developed to "clean" the screw by conveying material forward.
