Rotovib Destemmer Wine Press Destemmers Porex SA

The new ROTOVIB is a development which adds a linear, vibratory movement of the pin shaft relative to the destemmer cylinder. A vibrator is mounted on the pin shaft and drive is fixed on rubber mountings. The resulting longitudinal motion of the pin shaft is approximately 2 - 4mm at a frequency of 2300 oscillations per minute.

pressure. The pore space in a rock is occupied by fluids. In hydrocarbon reservoirs these fluids are hydrocarbon gasses, oil and an aqueous brine. We define the pore fraction of each of these asS g, S o andS w, respectively. Hence, S g + S o + S w = 1. The amount of each of these fluids present at a given level in the reservoir depends upon gravity

High pore fluid pressure may cause silent slip in the ...

The seismic image that we obtained shows a zone of high pore fluid pressure in the subducted oceanic crust located down-dip of a subducted ridge. We propose that these structures effectively extend a region of conditionally stable slips and consequently generate the silent slip.

Compressive Force - an overview ScienceDirect Topics

This pore-pressure behavior is called the Mandel–Cryer effect (Mandel, 1953; Cryer, 1963), and Abousleiman et al. (1996) present an analytical solution to which we compare our simulated results. We simulate this problem in two steps. The first step is the application of force that induces the pore-pressure increase.

Choosing the appropriate element for an analysis type

The pore pressure is interpolated linearly from the corner nodes. Curved element edges should be avoided; exact linear spatial pore pressure variations cannot be obtained with curved edges. For output purposes the pore pressure at the midside nodes of second-order elements is determined by linear interpolation from the corner nodes.

Gravel / ˈ ɡ r æ v əl / is a loose aggregation of rock fragments. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments.In the Udden-Wentworth scale gravel is categorized into granular gravel (2 to 4 mm or 0.079 to 0.157 in) and pebble gravel (4 to 64 mm or 0.2 to 2.5 in). ISO 14688 grades gravels as fine, medium, and coarse with ...
