Publication number: 20240133310Abstract: The system comprises a rotary turbomachine, including dry gas seals. A seal leak gas collecting line fluidly connects the at dry gas seals to the seal leak gas inlet of the ejector. A seal leak gas discharging line fluidly couples the dry gas seals with a seal leak gas discharge at a discharge pressure, lower than the seal leak gas pressure. A leak discharge control valve along the seal leak gas discharging line is adapted to divert at least part of the seal leak gas in the seal leak gas discharging line. Also, a method for recovering seal gas leaking from a dry gas seal arrangement is disclosed.Type: ApplicationFiled: March 4, 2022Publication date: April 25, 2024Inventors: Sergio CIPRIANI, Tiziano PELLEGRINI, Giacomo PAMPALONI, Eugenio QUARTIERI, Riccardo BECCALUVA, Stefano ROSSIN

Patent number: 6884947Abstract: An apparatus and a method for measuring the force (GL) applied by an elastically flexible element (5;71,71?) undergoing a pre-set elastic deformation, more specifically an element that carries a slider (3) and includes a thrust device that applies a force to the flexible element. The thrust device includes, for instance, a pneumatic nozzle (27;57,57?;28) for applying a force (R) to an intermediate portion (4) of the thin plate, at a thrust section (K). A position sensor (30;80) detects the height (z) of the slider—indicative of the deformation of the flexible element. The value (MF) of the moment of the applied torque when the height (ZF) of the slider indicates the pre-set elastic deformation of the flexible element, is utilized for calculating the force to be measured according to the formula GL=MF/L where L is the distance separating the slider from the section of weakness.Type: GrantFiled: July 6, 2001Date of Patent: April 26, 2005Assignee: Marposs Societa per AzioniInventor: Riccardo Cipriani
