System forming fence for the oil of lubricating the bearings of a centrifugal compressor fitted with seals for greater labyrinth installed in a confined environment.

摘要

This system forming a barrier for the oil of lubricating the bearings of a centrifugal compressor which is provided with seals labyrinth installed in a confined environment consists of a disc (24) integral with the shaft (5) of the compressor in the chamber facing the bearing located on the suction side of the compressor, at a point between the bearing and the labyrinth seal of the suction side, this disk having a circular edge in the form of an inverted u houses a stator ring (26) which is secured to the wall (27) of a chamber and arranged concentrically to said shaft, with which the rotating disk form a small passage fed continuously and kept filled by the centrifugal effect of the rotating disc, with an oil, forming a barrier, said stator ring comprising on its side facing the disk, a wedge-shaped portion (32) is inserted into a corresponding part of the disk and a tooth annualaire deflector (34) projecting from the - beyond the outer edge of the cavity.
