Abstract
A bearing support member for a high-lift multistage centrifugal pump. Relates to a bearing support component, in particular to a bearing support component of a high-lift multistage centrifugal pump. The bearing support component of the high-lift multistage centrifugal pump is convenient to maintain, and therefore the high-lift multistage centrifugal pump can keep a good working state. The bearing component comprises a bearing seat and a sliding bearing connected with the bearing seat, the bearing bush is arranged between the sliding bearing and the rotating shaft, and the bearing component and the bearing bush are of horizontal split structures. The utility model discloses an open structure in bearing part and axle bush all adopt the level, do not influence the centering nature of pump when dismantling the axle bush like this, also needn't demolish other spare parts of pump with regard to removable axle bush, fixed form about the bearing frame adopts respectively, reduced the maintenance cycle and the maintenance degree of difficulty of pump, improved the working property of pump.
Description
Technical field
The utility model relates to a kind of bearings parts, relates in particular to a kind of bearings parts of high-lift multi-stage centrifugal pump.
Background technique
High-lift multi-stage centrifugal pump is because of its lift height, require high-lift environment and be widely used in mine drainage etc., because its general rotating speed is than low-lift pump rotating speed height, and progression is more, so during the rotating shaft running it is had higher mechanical property and balance quality, and just seem particularly important this moment as the performance condition of the supporting part of rotating shaft, present pump is supported with rolling bearing and two kinds of structural types of sliding bearing, compare, sliding bearing all is better than rolling bearing on every performance, but sliding bearing is easy to wear, need add bearing shell between itself and rotating shaft, and bearing shell is needing to change after long-time running back produces wearing and tearing, but the rolling bearing that now uses often is integral type, at this moment replacing is got up cumbersome, has prolonged service cycle, and the working efficiency of high-lift multi-stage centrifugal pump is greatly reduced.
The model utility content
The utility model is at above-mentioned defective, and purpose is to provide a kind of bearings parts for maintenance of high-lift multi-stage centrifugal pump that makes convenient, thereby makes high-lift multi-stage centrifugal pump keep the bearings parts of the high-lift multi-stage centrifugal pump of works fine state.
The technical solution of the utility model is: the utility model is arranged in the rotating shaft at pump two ends, comprise bearing part and bearing shell, bearing part comprises bearing support and the sliding bearing that is attached thereto together, bearing shell is arranged between sliding bearing and the rotating shaft, and bearing part and bearing shell all adopt horizontal middle open type structure.
Bearing part of the present utility model and bearing shell all adopt horizontal middle open type structure, like this dismounting do not influence during bearing shell pump to neutrality, other component that also needn't remove pump are with regard to replaceable bearing shell, bearing support adopts up and down fixed form respectively, reduce the service cycle and the maintenance difficulty of pump, improved the service behaviour of pump.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1 is rotating shaft among the figure, and 2 is bearing part, and 3 is bearing shell.
Embodiment
The utility model is arranged in the rotating shaft 1 at pump two ends, comprise bearing part 2 and bearing shell 3, bearing part 2 comprises bearing support and the sliding bearing that is attached thereto together, and bearing shell 3 is arranged on sliding bearing and rotating shaft 1, and bearing part 2 and bearing shell 3 all adopt horizontal middle open type structure.
Claims (1)
