Abstract
The utility model discloses a take slide bearing's dive axle mixed flow pump, including dive axle mixed flow pump main shaft (2) and impeller (3) install antifriction bearing (1) on main shaft (2), install impeller (3) antifriction bearing (1) below, stretch out main shaft (2) impeller (3) below be fixed with on main shaft (2) end slide bearing (6). The utility model discloses that the impeller adopts is two fulcrum bearing structure of beam with both ends built in, comes as another strong point of locating through increasing axle body length, and axial force that its operation produced and radial force are undertaken by antifriction bearing and the slide bearing at impeller both ends respectively, compare the cantilever structure impeller that current single fulcrum supported, and the axial force and the radial force of production when it operates are all undertaken by a set of antifriction bearing on the impeller, the utility model discloses stability and reliability when improving the impeller operation can be shown, the life of antifriction bearing and dive axle mixed flow pump is effectively being prolonged.
Description
Technical field
The utility model belongs to water conservancy machinery technical field, specifically, relates to a kind of diving axle mixed flow pump with sliding bearing.
Background technique
Diving axle mixed flow pump is primarily of pump head and drive motor composition, and pump one, pump head and motor share a main shaft, and impeller is positioned at main shaft end.For reducing the impact of radial force on main shaft and bearing life of impeller, improving service life of equipment, except carrying out except static balancing and dynamic balance running to impeller, generally all can select main shaft and the bearing of large-size specification.The moment that impeller is larger on main shaft also can have a certain impact to the stability that equipment runs.
Summary of the invention
technical problem:the subject matter that the utility model solves is: provide a kind of diving axle mixed flow pump with sliding bearing, former rolling bearing is also as the main strong point, increase by place's sliding bearing as supplemental support point, plain bearing housing is fixed on the position of water-inlet horn mouth and main the tip of the axis, impeller location is positioned in the middle of two place's strong points, reduces the impact of the unfavorable factor such as moment on diving axle mixed flow pump life-span particularly bearing life.
technological scheme:for solving the problem, the technical solution adopted in the utility model is:
A kind of diving axle mixed flow pump with sliding bearing of the present utility model, comprise diving axle mixed flow pump main shaft 2 and impeller 3, described main shaft 2 is provided with rolling bearing 1, described impeller 3 is arranged on below described rolling bearing 1, described main shaft 2 stretches out below described impeller 3, and described main shaft 2 end is fixed with sliding bearing 6.
In described impeller 3 lower end, the impeller bottom plate 4 entering impeller 3 inside for anti-sealing is installed.
Described sliding bearing 6 is cylinder-shaped sleeve.
Water-inlet horn 7 is connected with described impeller 3; Described water-inlet horn 7 is provided with flow deflecting cone 5, and described flow deflecting cone 5 is arranged on outside described sliding bearing 6.
beneficial effect:compared with prior art, the beneficial effects of the utility model are:
1. sliding bearing cost is low, and diving runs high lubricating effect.
2., in running, between the outerface of spindle with sliding bearing internal surface, easily form liquid desert and do not occur directly to contact, reducing the sliding friction between two surface of contact.The absorbing effect of liquid desert also makes operation more steady.
3. in the utility model, for reducing the arm of force to the impact of impeller, what impeller adopted is two fulcrum support structures of beam with both ends built-in, is used as the strong point at another place's (main shaft end) by increasing axle body length, is born by sliding bearing compared with the radial force of long cantilever generation.The axial force that its running produces and radial force are born by the rolling bearing at impeller two ends and sliding bearing respectively, compare the cantilever beam structure impeller of existing single fulcrum support, the axial force produced during its running and radial force are all born by one group of rolling bearing of impeller upper end, the utility model can significantly improve stability when impeller runs and reliability, effectively extends the working life of rolling bearing and diving axle mixed flow pump.
Accompanying drawing explanation
Fig. 1 is the sectional view of existing diving axle mixed flow pump;
Fig. 2 is a kind of diving axle mixed flow pump sectional view with sliding bearing of the present utility model;
Have in figure: rolling bearing 1, main shaft 2, impeller 3, impeller bottom plate 4, flow deflecting cone 5, sliding bearing 6 and water-inlet horn 7.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in detail.
As shown in Figure 2, the diving axle mixed flow pump of band sliding bearing of the present utility model forms primarily of rolling bearing 1, axle mixed flow pump main shaft 2, impeller 3, impeller bottom plate 4, flow deflecting cone 5, sliding bearing 6 and water-inlet horn 7.Roller bearing 1 is arranged on main shaft 2, and impeller 3 is arranged on the main shaft 2 below rolling bearing 1, impeller bottom plate 4 water shutoff of impeller 3 lower end; Compared with prior art, the utility model extends the length of main shaft 2, and main axis length extends to water-inlet horn 7 place, stretches out below impeller 3.Sliding bearing 6 is fixed on main shaft 2 end, and in the utility model, sliding bearing 6 is cylinder-shaped sleeve.The main strong point of main shaft 2 is born by roller bearing component 1, and supplemental support point is born by sliding bearing 6.Flow deflecting cone 5 is arranged on water-inlet horn 7, and sliding bearing 6 bolt is fixedly mounted on flow deflecting cone 5.
In the utility model specific embodiment, roller bearing component 1 as the main strong point, the axial force produced when bearing water pump operation and most of radial force.The plain bearing element 6 increased, as the supplemental support of axle head, bears the part radial force produced when water pump operation, farthest avoids the oscillation phenomenon that submersible pump causes because radial force is uneven in running.The liquid formed in relative movement between plain bearing element 6 internal surface and main shaft 2 outer surface is unconcerned, the part surface of two relative movement is not directly contacted, reduce the frictional loss between two slip surfaces, while improving the operation stability of rotary component, also extend the service life of equipment of diving axle mixed flow pump.
