Abstract

Dispositivo di pompaggio per fluidi multifase in cui in una carcassa a disco con profilo periferico toroidale e provvista sulla sua periferia interna di un tubo del tipo tubo di Pitot connesso ad un condotto di mandata è montata ruotante una girante a pale disposta eccentricamente rispetto all'asse della carcassa in posizione circa diametralmente contrapposta al detto tubo di Pitot, nonchè un secondo condotto di mandata situato nella zona della carcassa contrapposta al condotto di ammissione al piano contenente sia l'asse della carcassa che l'asse della girante stessa ed in prossimità di quest'ultimo asse, valvole automatiche essendo previste nei condotti.Pumping device for multi-phase fluids in which in a disc casing with a toroidal peripheral profile and provided on its internal periphery with a Pitot tube-type tube connected to a delivery duct, a rotating impeller with blades positioned eccentrically with respect to the axis is mounted rotating of the casing in a position approximately diametrically opposed to said Pitot tube, as well as a second delivery duct located in the area of the casing opposed to the duct for admission to the plane containing both the axis of the casing and the axis of the impeller itself and near this the last axis, automatic valves being provided in the ducts.
