    Abstract: The adjoining edges of bucket covers (12) are sealed one to the other. A brush seal (18) projecting from a stationary shroud (14) overlies the bucket covers. A joint at which the adjacent covers sealingly engage each other precludes radial outflow of high pressure fluid into bristles (22) of the brush seal, preventing radial and axial deflection of the bristles and consequent failure of the bristles. The joints between the covers may comprise lap (41) or tongue-and-groove joints (74).

    Abstract: A fracturing system is described. The system includes an electric motor-driven pumping sub-system, configured to pump a pressurized fracturing fluid into at least one wellbore, under high pressure conditions sufficient to increase the downhole pressure of the wellbore, to exceed that of the fracture gradient of the solid matter surrounding the wellbore. The system also includes an electric power generation sub-system that provides energy to the pumping sub-system. The electric power generation sub-system includes a multitude of electric motors that are powered by a single electrical feed source.

    Abstract: A flow control system for drilling a well comprises a conduit defining a channel configured to accommodate a drill pipe and a flow of a returning drilling fluid, and an acoustic sensor array configured to detect a flow rate of the returning drilling fluid. The flow control system further comprises a flow control device configured to control the flow rate of the returning drilling fluid and to be actuated in response to an event detected by the sensor array, the flow control device being proximate to the sensor array.

    Abstract: PROBLEM TO BE SOLVED: To suppress reduction of abrasion of seta and seal performance when an impeller blade cover is rotated along a brush seal, in a sealing device formed between the impeller blade cover of a rotary impeller and a fixed shroud for enclosing the impeller blade cover. SOLUTION: A seal device is provided with a fixed shroud 14 having a brush seal 18 extending along a circumferential direction, and an impeller blade cover 12 opposed along a radial direction. Furthermore, the brush seal 18 is provided with seta extending so as to engage with a seal surface of the impeller blade cover 12 to be rotated, and an inclining surface or a bending surface is formed on a front edge of the impeller blade cover 12 in a rotational surface including the brush seal 18.

    Abstract: PROBLEM TO BE SOLVED: To provide a brush seal which can maintain a sealing ability even though it is used for a high pressure rotor, and which can cope with a transient radial movement of the rotor. SOLUTION: A brush seal includes a bundle 16 of bristles attached to a seal housing 12, a seal member 18 slidably attached to the seal housing 12, a mechanical spring 20 arranged in a compressed condition between the seal housing 12 and the seal member 18. The seal member 18 has a planar first surface part 48 which is parallel with a first surface 22 of the seal housing 12, and is made into slidable contract with the first surface 22, and a second planar surface part 50 which is in parallel with the first side 40 of the bundle of bristles and is made into slidable contact with the first side 40.

    Abstract: PROBLEM TO BE SOLVED: To provide a brush seal segment advantageous for sealing a clearance between a rotor of a rotary machine such as a steam turbine and a circumferential casing when it is arranged in the circumferential direction together with the other segment. SOLUTION: An annular support plate 124 has a rim 140 giving a boundary to a face on the upstream side and a face on the downstream side on an inner side in the radial direction at the same time. Inclined bristles 150 abut on the face on the upstream side. The rim is designed in such a way that the bristles can recover from rotor rubbing. According to a design, the rim operates as a labyrinth seal tooth and is shaped so as to deform on the opposite side in the longitudinal direction to the face on the upstream side under a force in the radial direction. According to another design, the rim has a second part protruding on an inner side further close to an edge extending in the radial direction, and this second part only operates as a labyrinth seal tooth.

    Abstract: PROBLEM TO BE SOLVED: To provide a seal assembly using brush seal for minimizing the steam leak in a steam path between a rotary shaft of a turbine and a casing surrounding in the circumferential direction in the turbine region of a steam turbine. SOLUTION: A steam turbine 10 having a shaft 12 and a first (for example, high pressure) turbine section 16 includes a first bearing 20 isolated in the longitudinal direction from the first turbine section, and in the longitudinal direction, further a first brush seal assembly 22 is provided which is positioned between the first turbine section and the first bearing and has bristles arranged near the shaft in the radial direction. The steam turbine does not include any backup seal for the bristles of the first brush seal assembly. A second brush seal assembly 38 is positioned between the first turbine section 16 and a second (for example, middle pressure) turbine section 34, and between these no interposed bearing exists.

    Abstract: PROBLEM TO BE SOLVED: To secure engagement with a rotating part by positively slackening bristles in a direction toward the rotating part by a flow of fluid. SOLUTION: A brush seal includes a large number of bristles 26 fixed on a fixed part 14 forming a row along the circumferential direction and arranged in a circumference of a rotating part 18, the bristles 26 are supported in an open sided state toward the rotating part 18 making a constant angle against a radius of the rotating part 18, and head ends of the bristles 26 are engaged with the rotating part 18. Additionally, the bristles 26 are supported by plates 28, 30 on their both sides along the axial direction. These plates 28, 30 have channels to slacken the bristles 26 toward the rotating part 18 by spraying introduced fluid in a pressurized state on the bristles 26. Consequently, the head ends of the bristles are pressed on a surface of the rotating part and a sealing state is improved.
