DEVICE FOR EXAMINATION OF PROCESSES OF FILTRATION AND DETERMINATION OF CHARACTERISTICS OF FLUIDS AND POROUS BODIES Russian patent published in 1999 - IPC

FIELD: modeling of filtration and forcing of various fluids through capillary and porous bodies. SUBSTANCE: device has two hydraulic cylinders with pistons installed in bodies. Each hydraulic cylinder is provided with pressure transducer and movement sensor. Pressure chambers of hydraulic cylinders communicate with conduits feeding fluids to butts of bodies housing porous medium. These bodies are put on common base. Drives of pistons ensure translational and rotary motion of pistons with use of pairs screw and nut ". Screws are linked to pistons and to motors. Bodies are spring-loaded by means of elastic members positioned between butt of body and nuts. Pressure transducers of each hydraulic cylinder are made in the form of indicator fixing relative displacement of nut of bodies. Movement sensors are manufactured in the form of indicator fixing relative displacement of pistons and body. EFFECT: provision for measurement of filtration and physical properties of materials and properties of fluids in wide range of pressures under reversible mode according to desired law with low measurement errors. 1 cl, 9 dwg
