Title:
遠心分離機用の封止装置
Document Type and Number:
Japanese Patent JP4209473
Kind Code:
B2
Abstract:
A simple but still effective sealing device to separate two openings (4, 5), which are arranged at a distance from each other in the outer casing (3) of a shaft suspension unit (1), which supports a shaft (2) of a centrifugal separator in a bearing (8, 9), the shaft extending axially through at least one opening (4) into a space surrounding the shaft (2) in the outer casing (3). The sealing device is provided with sealing elements (12, 13), one connected to the outer casing (3) and one connected to the shaft (2), which surround the shaft (2) and divide the space in two departments (15, 16) connected to one opening each (4, 5, respectively). The sealing elements form between themselves a narrow gap (14) surrounding the shaft (2), which prevents the flow of gas between the departments (15, 16). One of the sealing elements (12, 13) has a channel (21), which has an opening (23) in a central part of the gap (14), for the supply of a sealing liquid under pressure to the gap (14) in such a way that oil flows from the opening (23) through the gap (14) and out into the two departments (15, 16).
