Description
Technical field
The present invention relates to impeller housing technical fields, more particularly to a kind of impeller housing bushing.
Background technique
Axial-flow pump during operation, impeller housing be it is fixed, the outer Surface of Sphere of blade and impeller indoor spherical surface there is
Gap, in order to improve the wearability and cavitation resistance of water pump, save the cost needs to add impeller buss in impeller housing.But
It is that in actual operation, since the installation of bushing is generally installation by adhering, the disassembling, assembling and replacing of bushing is relatively complicated, in axis
The case where being easy to appear casing slip, offset in stream pump operation process, it is difficult to guarantee the stability of water pump operation.Therefore, in order to
Solve the problems, such as above-mentioned, the present invention provides a kind of new technical solutions.
Summary of the invention
The object of the present invention is to provide a kind of simple, convenient dismounting and the significant impeller housing bushings of locating effect.
Used technical solution is the present invention in view of the above technical defects: a kind of impeller housing bushing, including bush body,
The outer circle of the bush body is evenly arranged with multiple detent slots, and annular is provided with more between the bush body outer rim and inner hole
A bearing gear is adapted with impeller, and the bush body is hingedly provided with press strip at the both ends of each bearing gear, the single pressure
Item rotates relative to bush body and abuts impeller housing inner wall, and the outer circle of the bush body is provided with multiple corresponding with press strip convex
Edge.
Further, the end face that the single press strip abuts impeller housing inner wall is provided with multiple fins.
Further, the single bearing gear is domes, and is detachable connection with bush body.
Further, the middle part insertion of the bearing gear of domes is equipped with reinforcement block, and reinforcement block can be monoblock type or divide
Any one in body formula structure.
The beneficial effects of the present invention are: the present invention is hingedly provided with press strip on bushing, in bushing installation by adhering in leaf
Press strip is rotated after hub cap and abuts outer casing inner wall, greatly enhances locating effect, and the fin on press strip can effectively reduce lining
The case where set sliding offset, guarantee the stabilization of water pump operation performance, and setting bearing gear is adapted with impeller on bushing, greatly
The phenomenon that big reduction bushing is prone to wear, it is durable, the bearing of serious wear need to only be kept off to disassembling, assembling and replacing, it is easy to operate
Fast, convenient and practical.
Detailed description of the invention
Present invention is further described in detail with reference to the accompanying drawings and detailed description.Fig. 1 is structure of the invention
Schematic diagram.Wherein: 1, bush body, 2, detent slot, 3, bearing gear, 4, press strip, 5, flange, 6, fin, 7, reinforcement block.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, does not restrict the protection scope of the present invention.
A kind of impeller housing bushing as shown in Figure 1, including bush body 1, the outer circle of bush body 1 are evenly arranged with multiple
Detent slot 2, annular is provided with multiple bearing gears 3 and is adapted with impeller between 1 outer rim of bush body and inner hole, and bush body 1 exists
The both ends of each bearing gear 3 are hingedly provided with press strip 4, and single press strip 4 is rotated relative to bush body 1 abuts impeller housing inner wall, lining
The outer circle of set ontology 1 is provided with multiple flanges 5 corresponding with press strip 4.
In the present embodiment, the end face that single press strip 4 abuts impeller housing inner wall is provided with multiple fins 6, is embedded in bushing
Formula is mounted on after impeller housing press strip 4 rotating abutting outer casing inner wall, so that the fin 6 on press strip 4 is close to inner wall, it can be effective
The case where reducing casing slip offset.
In the present embodiment, single bearing gear 3 is domes, and is detachable connection, arch knot with bush body 1
It is preferable that the bearing of structure keeps off 3 pressure-bearing effects, is hardly damaged, and after bearing keeps off 3 serious wears only need to by its disassembling, assembling and replacing,
It is simple and convenient.
In the present embodiment, the middle part insertion of the bearing gear 3 of domes is equipped with reinforcement block 7, and reinforcement block 7 can be whole
Any one in formula or split type structure, reinforcement block 7 is provided with the intensity for being conducive to improve bearing gear 3, durable, whole
Formula reinforcement block 7 dismount it is simple and convenient, but 7 somewhere of reinforcement block cracking be easy to extend in overall structure, service life is shorter；Point
Body formula 7 service life of reinforcement block are longer, but dismount it is relatively complicated, can be according to actual conditions flexible choice monoblock type or split type
The reinforcement block 7 of structure.
The beneficial effects of the present invention are: the present invention is hingedly provided with press strip on bushing, in bushing installation by adhering in leaf
Press strip is rotated after hub cap and abuts outer casing inner wall, greatly enhances locating effect, guarantees the stabilization of water pump operation performance, Er Qie
Setting bearing gear is adapted with impeller on bushing, greatly reduces the phenomenon that bushing is prone to wear, durable, easy to operate fast
Victory, it is convenient and practical.
The above described is only a preferred embodiment of the present invention, being not the limit for making any other form to the present invention
System, and made any modification or equivalent variations according to the technical essence of the invention, still fall within present invention model claimed
It encloses.
