摘要： A thermal actuator for a rotating shaft shutdown seal that has a piston with a portion of its axial length enclosed within a cylinder shell with a material, such as a fusible link that changes state or deforms above a given temperature, interposed between a closed end of the cylinder and one end of the piston. The piston is spring biased toward the material and moves toward the closed end of the cylinder when the given temperature is reached and the deformation or change of state of the material makes room for the piston to move toward the closed end. Movement of the piston is transferred through a piston rod to activate the seal.

摘要： Provided is a shaft sealing mechanism that, by making the pressure of fluid that flows between thin-plate seal pieces uniform, can eliminate the fluid pressure difference that acts on an upper surface and a lower surface of the thin-plate seal pieces and suppress vibration of the thin-plate seal pieces. A shaft sealing mechanism (11) that partitions an annular space (14) that is formed between a fixed part (12) and a rotating shaft (13) into a high-pressure-side region and a low-pressure-side region, that obstructs the flow of a fluid (G), and that is provided with: a plurality of annularly laminated thin-plate seal pieces (22) that are fixed to an annular seal housing (21) that is provided to the fixed part (12) and are in sliding contact with the rotating shaft (13) ; and an annular low-pressure-side plate (26) that is sandwiched and held such that a low-pressure-side gap (´L) is formed between the seal housing (21) and a low-pressure-side side edge part (22d) of the thin-plate seal pieces (22). The thin-plate seal pieces (22) have pressure-conduction holes (31) that are formed further to the inside in the radial direction of the rotating shaft than an inner-circumferential-side tip part (26a) of the low-pressure-side plate (26).

摘要： Sliding parts by which a sealing function of the sealing faces can be maintained for a long time by actively taking a fluid into sealing faces and discharging the fluid from the sealing faces while meeting contradictory conditions of sealing and lubrication so as to prevent concentration of sediment causative substances on the sealing faces and hence prevent generation of sediment are provided.
A fluid circulation groove 10 including an inlet section 10a where a fluid comes in from a high pressure fluid side, an outlet section 10b where the fluid goes out to the high pressure fluid side, and a communication section 10c that provides communication between the inlet section and the outlet section is provided in at least one of sealing faces of a pair of sliding parts that slide on each other. The fluid circulation groove 10 is isolated from a low pressure fluid side by a land section R. A section of a bottom wall of the fluid circulation groove 10 is formed in a round bottom shape.

摘要： A gas supply system for a mechanical seal turns on the gas supply at a pressurized flow rate at the time of compressor case pressurization and remains on during compressor rotation until pressure is adequate. The gas supply system has an intensifier that includes a pair of mechanically inter-connected pneumatic pressure cylinders which comprise a drive cylinder that affects movement of a boost cylinder wherein the displacement of these mechanically interconnected pistons in the drive cylinder and boost cylinder intensifies the pressure being discharged by the boost cylinder and supplied as a barrier fluid to the mechanical seal. The intensifier uses a control valve and operating system which includes a fast-acting 5/2-way solenoid valve having a feedback loop connected to a control system which includes a microprocessor that controls valve actuation.

摘要： A turbomachine with a rotary shaft supporting a turbine wheel is supported for rotation in a housing. The shaft extends through a bore in the housing and a bearing assembly being disposed in the bore. At least one end of the shaft has a primary seal and a secondary seal. The primary seal comprises a non-contact seal defined by an annular clearance between a first non-rotating seal element and a second seal element that rotates with the shaft. The primary seal is arranged to receive lubricating oil from the bearing assembly. An oil slinging feature is provided between the primary and secondary seals.

摘要： The axial reaction force generated by a subsea pump or compressor is partially counteracted by a pressure differential in a barrier fluid across a thrust element. The pressure differential is created using impellers or other structures on the thrust element that increases the barrier fluid pressure on one side of the thrust element when the main shaft of the pump or compressor is rotated. The pressure differential across the thrust element partially offloads the bearing surface of the thrust element.
