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.

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 thermal actuator for a rotating shaft shutdown seal that has a piston with a portion of its axial length enclosed within a chamber shell with a material that expands upon a rise in temperature. The portion of the actual length of the piston within the chamber has at least two different diameters with the larger diameter leading in the direction of travel of the piston. Upon a rise in temperature, expansion of the material surrounding the piston within the chamber creates a force on the piston in the desired direction of travel. Below a preselected temperature the piston is positively locked with a passive release when the preselected temperature is reached.

摘要： An assembly for a gas turbine engine includes a seal and a flow diverter. The flow diverter is disposed adjacent the seal to direct a secondary gas flow that passes across the seal away from a rotor cavity such that the secondary gas flow travels back toward a main gas flow path of the gas turbine engine.

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.
