Problems solved by technology

[0009] In this variant, the ring has the advantage that the radial and axial bearings can be driven and adjusted as far as possible individually and a stable operating position can be reached, while the disadvantage is that two rows are required for stabilization and for controlling the two bearings Supply lines that must be supplied and controlled independently of each other, i.e. require at least two sets of supply pumps that on the one hand have a rather high power, including the relevant control mechanisms or additional hydraulic parts such as throttle valves, filters, etc., so that they are effectively sealed The power increase is partially or even completely exhausted by the required pump power or by throttling losses
Furthermore, producing such a seal is complex in terms of process technology, since twice as many holes and lines are required

Embodiment Construction

[0038] Before actually describing, some terms are defined and elaborated below.

[0039] Generally, the terms "support" are used such as groove and bearing surface, which in this application denote ring-shaped or cylindrical structures, respectively. In this case, the support member or bearing surface can have any width and depth or height and can be continuous in the circumferential direction or partially interrupted at one or several points. Of course, the support member may have any cross-sectional shape, for example triangular grooved, and need not be grooved.

[0040] Hydrostatic bearings always consist of mutually opposing bearing surfaces, wherein at least one bearing element, such as a groove, groove, etc., is provided on at least one bearing surface. If a number of bearings are arranged on the circumference, since one bearing is partially broken as described above, a plurality of hydrostatic bearings arranged on the circumference must also be mentioned. For the sake...

Abstract

The invention relates to a seal arranged between relatively moving parts of a hydraulic machine, such as an impeller, and a housing, said parts being almost hermetic, but still simple in construction, characterized in that a seal is supported on two hydrostatic bearings superior.

Description

technical field [0001] The invention relates to a device for sealing a gap between two relatively moving parts of a hydraulic machine, which has at least one seal which is supported relative to the two moving parts by means of at least one hydrostatic bearing each, each The hydrodynamic bearing comprises bearing surfaces facing each other and at least one of the bearing surfaces has at least one support element, such as a groove, groove, etc., to which the hydraulic bearing medium can be supplied via at least one supply line. Furthermore, the present invention discloses methods of operation and operation of such seals. Background technique [0002] Due to the unfavorable operating conditions in the area of ​​the outer diameter of the impeller of hydraulic machines and here mainly for large machines with an impeller diameter of several meters, it is currently impossible to establish a reliable seal between the impeller and the housing, except for clearance losses. In additio...
