Abstract
The utility model belongs to the technical field of the centrifugal pump, concretely relates to but vertical multistage centrifugal pump's quick replacement slide bearing device. The sliding bearing device capable of being replaced quickly of the vertical multistage centrifugal pump comprises a water inlet section base and a pump shaft, wherein a sliding bearing seat is assembled at one end, located on the water inlet section base, of the pump shaft through a fixing bolt, a sliding bearing outer sleeve is arranged in the sliding bearing seat, and the sliding bearing outer sleeve is fixed relatively through a seam-riding bolt; the pump shaft is sleeved with a sliding bearing inner sleeve, and is blocked and limited by a nut at the end part of the pump shaft. The beneficial effects are as follows: the operation complexity of the sliding guide bearing of the vertical multistage centrifugal pump is reduced, the operation is simple and convenient, the whole pump core is required to be taken out for replacement in the whole replacement process relative to the traditional mode, the time from about half to more than two thirds can be saved, the structure is simple, and the assembly is convenient.
Description
Technical Field
The utility model belongs to the technical field of the centrifugal pump, concretely relates to but vertical multistage centrifugal pump's quick replacement slide bearing device.
Background
If a shaft end guide bearing needs to be replaced in a vertical multistage centrifugal pump on the market at present, a pump body needs to be opened, a whole set of pump core assemblies such as an impeller, a distance adjusting sleeve and a pump shaft are taken out, and then the sliding guide bearing is taken down for replacement. The sliding guide bearing is a vulnerable part compared with other parts, once the sliding guide bearing needs to be replaced, the number of hands and feet is large, the operation is complex, the number of parts to be disassembled and assembled is large, and the vertical multi-stage centrifugal pump has the characteristics of large number of parts and small size, so that once the parts are carelessly disassembled and assembled, the parts are easily damaged or lost, and unnecessary troubles are caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a remedy prior art's defect, but provide a vertical multistage centrifugal pump's quick replacement slide bearing device.
The utility model discloses a realize through following technical scheme:
a sliding bearing device capable of being replaced quickly for a vertical multistage centrifugal pump comprises a water inlet section base and a pump shaft, wherein a sliding bearing seat is assembled at one end, located on the water inlet section base, of the pump shaft through a fixing bolt, a sliding bearing outer sleeve is arranged in the sliding bearing seat, and the sliding bearing outer sleeve is fixed relatively through a seam-riding bolt; the pump shaft is sleeved with a sliding bearing inner sleeve, and is blocked and limited by a nut at the end part of the pump shaft.
Furthermore, the joint of the sliding bearing seat and the water inlet section base is provided with a dismounting bolt, and the sliding bearing seat is ejected out of the water inlet section base through fastening the dismounting bolt after the fixed bolt is dismounted.
The utility model has the advantages that: the operation complexity of the sliding guide bearing of the vertical multistage centrifugal pump is reduced, the operation is simple and convenient, the whole pump core is required to be taken out for replacement in the whole replacement process relative to the traditional mode, the time from about half to more than two thirds can be saved, the structure is simple, and the assembly is convenient.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 water inlet section base, 2 sliding bearing seat, 3 nuts, 4 fixing bolts, 5 sliding bearing inner sleeves, 6 sliding bearing outer sleeves, 7 riding bolts, 8 dismounting bolts and 9 pump shafts.
Detailed Description
Fig. 1 shows an embodiment of the present invention. The utility model relates to a quick-replaceable sliding bearing device of a vertical multistage centrifugal pump, which comprises a water inlet section base 1 and a pump shaft 9, wherein one end of the pump shaft 9, which is positioned at the water inlet section base 1, is assembled with a sliding bearing seat 2 through a fixing bolt 4, a sliding bearing outer sleeve 6 is arranged in the sliding bearing seat 2, and is relatively fixed by a seam-riding bolt 7; the pump shaft 9 is sleeved with a sliding bearing inner sleeve 5, and is blocked and limited by a nut 3 at the end part of the pump shaft 9.
Furthermore, the junction of the sliding bearing seat 2 and the water inlet section base 1 is equipped with a dismounting bolt 8, and the sliding bearing seat 2 is ejected out from the water inlet section base 1 through fastening the dismounting bolt 8 after the fixing bolt 4 is dismounted.
When the sliding bearing device of the vertical multistage centrifugal pump is used, the sliding bearing outer sleeve 6 is arranged in the sliding bearing seat 2 and is relatively fixed by the riding bolt 7; a sliding bearing inner sleeve 5 is arranged on a pump shaft 9 and fixed by two round nuts 3, one end, provided with the sliding bearing inner sleeve 5, of the pump shaft 9 in the pump core assembly extends into the water inlet section base 1 during installation and is radially fixed by a sliding bearing seat 2 provided with a sliding bearing outer sleeve 6, and the sliding bearing seat 2 is fixed on the water inlet section base 1 by a fixing bolt 4.
When in disassembly, the fixing bolt 4 is loosened, then the sliding bearing seat 2 is ejected out and taken down by the disassembling bolt 8, and the sliding bearing outer sleeve 6 can be taken out for replacement by loosening the joint-riding bolt 7; the sliding bearing inner sleeve 5 can be taken out for replacement by loosening the two round nuts 3 on the pump shaft 9, and the purpose of replacing the sliding bearing can be achieved without disassembling the pump shaft.
The present invention is not limited to the above embodiments, and any person should learn to make under the teaching of the present invention and the present invention has the same or similar technical solution, and all fall into the protection scope of the present invention.
The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
