Abstract
The utility model provides a sliding bearing, including the bearing body, the face that the bearing body contacted with the impeller shaft is the bearing surface, is provided with first lubrication groove along the axial direction of bearing surface, and a terminal surface of bearing body corresponds first lubrication groove and is provided with the second lubrication groove, and first lubrication groove is linked together with the second lubrication groove, is provided with reticulation shape cistern on the bearing surface. The utility model discloses bearing surface at the bearing body is provided with first lubrication groove and second lubrication groove, and the cooperation between bearing surface and the impeller shaft all has certain clearance, the medium that gets into in the condensate pump can follow the first lubrication groove of second lubrication groove inflow and clearance within a definite time, thereby lubricated bearing surface, be provided with reticulation shape cistern in addition on the bearing surface, can avoid lubricated blind area, can effectively prolong the lubricated time of medium to bearing surface, make slide bearing have higher resistance to compression, wear resistance and excellent lubricating property, thereby greatly reduced slide bearing and the mechanical noise and the vibration that the impeller shaft friction produced.
Description
Technical Field
The utility model relates to a slide bearing field, in particular to slide bearing for among condensate pump.
Background
At present, a condensate pump adopts a common centrifugal pump type, one or two centrifugal impellers apply work to convey condensate water to next-stage equipment, and a mechanical seal is arranged at the communication position of an output shaft and the outside to prevent a medium in the pump from leaking to the outside environment. The impeller shaft is usually supported by a rolling bearing cantilever, but the rolling bearing cantilever supports the impeller shaft, so that vibration and noise caused by friction between the impeller shaft and the rolling bearing are large when the condensate pump runs.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a greatly reduced slide bearing and the mechanical noise and the slide bearing of vibration that impeller shaft friction produced.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides a sliding bearing for support the impeller shaft and do rotary motion in the condensate pump, includes the bearing body, the face that the bearing body contacted with the impeller shaft is the bearing surface, follows the axial direction of bearing surface is provided with four first lubrication grooves that are the annular array and arrange, the terminal surface of bearing body corresponds first lubrication groove is provided with the second lubrication groove, first lubrication groove with the second lubrication groove is linked together, be provided with reticulation shape cistern on the bearing surface.
Further, the mesh-shaped liquid groove is circular.
Furthermore, the groove depth of the net-grain-shaped liquid groove is 2-5 mm.
Further, the groove depth of the mesh-shaped liquid groove is 3 mm.
The utility model has the advantages that:
the utility model discloses a slide bearing, and the axial direction at the bearing surface of bearing body is provided with four first lubrication grooves that are the annular array and arrange and is provided with the second lubrication groove at a terminal surface of bearing body, and the cooperation between bearing surface and the impeller shaft all has certain clearance, the medium that gets into in the condensate pump can follow the first lubrication groove of second lubrication groove inflow and clearance within a definite time, thereby lubricated bearing surface, be provided with reticulation shape cistern on the bearing surface in addition, can avoid lubricated blind area, can effectively prolong the lubricated time of medium to the bearing surface, make slide bearing have higher resistance to compression, wear resistance and excellent lubricating property, thereby greatly reduced slide bearing and the mechanical noise and the vibration that the impeller shaft friction produced.

Further, the mesh-shaped liquid tank 5 is circular.
Furthermore, the depth of the groove 5 of the mesh-shaped liquid groove is 2-5 mm.
Further, the groove 5 of the mesh-shaped liquid tank has a depth of 3 mm.
The utility model discloses a slide bearing, and be provided with four first lubrication groove 3 that are the annular array and arrange and be provided with second lubrication groove 4 at the terminal surface of bearing body at the axial direction of bearing surface 2 of bearing body 1, and the cooperation between bearing surface 2 and the impeller shaft all has certain clearance, the medium that gets into in the condensate pump can follow second lubrication groove 4 and flow in first lubrication groove 3 and clearance within a definite time, thereby lubricated bearing surface 2, be provided with reticulation shape cistern 5 on the bearing surface 2 in addition, can avoid lubricated blind area, can effectively prolong the medium to bearing surface 2's lubricated time, make slide bearing have higher resistance to compression, wear resistance and excellent lubricating property, thereby greatly reduced slide bearing and the mechanical noise and the vibration that the impeller shaft friction produced.
The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
