Patent number: 10816006Abstract: The turbomachine comprises a stationary casing with a rotating member configured to rotate about a rotation axis in the stationary casing. The turbomachine further includes a rotating balance drum, arranged for co-rotation with the rotating member. A stationary sleeve is arranged in a fixed relationship with the stationary casing and surrounds the balance drum. The stationary sleeve comprises a plurality of consecutively arranged sleeve sections. A fluid channel is defined by an outer surface of the balance drum and an inner surface of the stationary sleeve. Between at least one pair of sequentially arranged upstream sleeve section and downstream sleeve section an annular chamber is provided, fluidly coupled to the fluid channel. Shunt holes are arranged on the upstream sleeve section, each shunt hole having a shunt hole inlet on an inner surface of the upstream sleeve section, and a shunt hole outlet in the annular chamber.Type: GrantFiled: September 7, 2016Date of Patent: October 27, 2020Assignee: NUOVO PIGNONE SRLInventors: Fabrizio Milone, Giulio Elicio

Patent number: 9810233Abstract: An axially-split turbomachine comprising a casing comprised of a first casing portion and a second casing portion, forming a housing for a rotor arranged for rotation therein. The rotor comprises a shaft and at least one impeller mounted on the shaft. The casing comprises at least one shaft passageway through which the shaft extends from the interior of the casing towards the exterior of the casing. The sealing arrangement comprises a linear sealing member, extending between the first and the second casing portions. The sealing arrangement further comprises at least one sealing ring portion surrounding said at least one shaft passageway. The sealing ring portion and the linear sealing member form a continuous sealing body.Type: GrantFiled: December 17, 2013Date of Patent: November 7, 2017Assignee: Nuovo Pignone SrlInventors: Carlo Del Vescovo, Donato Antonio Rip, Fabrizio Milone

Patent number: 9803644Abstract: A back-to-back centrifugal pump comprising a pump inlet, a pump outlet, a pump shaft, a set of first stages, and a set of second stages in a back-to-back arrangement. Between the two sets of stages an intermediate crossover module is arranged. The first and second sets of stages comprise respective first outer diaphragms and second outer diaphragms. The outer diaphragms and the intermediate crossover module are stacked together and form a pump casing. The intermediate crossover module forms at least one axial transfer channel between the two sets of stages, and a fluid connection between the set of second stages and the pump outlet. The second diaphragms comprise each at least one peripherally arranged through aperture. The through apertures are aligned to form at least one passageway, which fluidly connects the axial transfer channel with a most upstream one of the impellers of the second set of stages.Type: GrantFiled: December 2, 2013Date of Patent: October 31, 2017Assignee: Nuovo Pignone SRLInventors: Lorenzo Bergamini, Donato Antonio Ripa, Fabrizio Milone
