  • Patent number: 9518473
    Abstract: A shaft seal insert for the shaft seal of a turbomachine extending along a rotational axis includes:—a rotor part attachable on a shaft of a rotor,—a stator part insertable into a stator receiving area, and—a dry gas seal having a rotating seal element attached to the rotor part and a fixed seal element attached to the stator part to seal an intermediate space between the two seal elements, which lie opposite each other on a sealing surface extending radially and in the circumferential direction. A labyrinth seal is provided on a high-pressure side in a serial arrangement with the dry gas seal to seal the intermediate space, having a fixed and rotating labyrinth seal parts. The fixed labyrinth seal part is part of the stator part or is fixed thereto. The rotating labyrinth seal part is part of the rotor part or is fixed thereto.

  • Publication number: 20140027985
    Abstract: A shaft seal arrangement for turbomachine is presented. The arrangement has a high and a low pressure side at each axial end, a rotor and a fixed stator part, and a dry gas seal. An additional shaft seal is provided at end of high-pressure side in a serial to seal intermediate space and has a fixed and a rotating shaft seal part. A central shaft seal surface extends in circumferential and in axial direction and is arranged between fixed and rotating shaft seal part on a fifth diameter coaxially with respect to rotational axis. A fourth stationary seal is arranged between fixed seal element and stator part on a fourth diameter to seal a first differential pressure. Damage due to changes of thrust is prevented if the dry gas seal is defective by difference between the fourth and fifth diameter being less than 10% of the firth diameter.

  • Publication number: 20120055335
    Abstract: A drain liquid relief system for a subsea compressor is provided. The system includes a suction scrubber a drain storage tank for collecting drain liquid contaminating the compressor flow in the drain storage tank. The system further includes an intermittently pressurizing device and a suction line connected to the bottom of the drain storage tank. The suction scrubber is connected to the compressor suction nozzle and/or a compressor casing drain line, the suction scrubber being further connected, via a first check valve, to the drain storage tank for collecting the drain liquid in the drain storage tank. The intermittently pressurizing device is adapted to intermittently pressurize the drain storage tank to intermittently blow the drain liquid out of the drain storage tank through the suction line.
