Description
Technical field
The utility model belongs to centrifugation pump technical field, specially a kind of centrifugal pump impeller.
Background technique
Water pump is widely used in every field, it sends the mechanical energy of prime mover or other external energies to liquid
Body increases liquid energy, is mainly used to convey liquid to include water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal etc..
Water pump includes centrifugal pump and mixed-flow pump etc..And have certain gap at centrifugal pump suction chamber inner edge and blade wheel chamber's water inlet outer rim,
If this gap is excessive, the high pressure water flowed out from impeller will leak back into the import of impeller by the gap, so that reducing pump
Water yield reduces the efficiency of pump, and in order to avoid liquid reflux in centrifugal pump use process, spy increases floating in impeller assembly
Choma.Floating choma is not contacted with impeller surface under normal circumstances, if floating choma and impeller surface easy phase when having a liquid residual
Mutually paste.When impeller rotates, if floating choma is pasted with impeller, the rotation synchronous with impeller under the action of frictional force of floating choma
Turn, but when floating choma is different from impeller rotation, i.e., the speed of floating choma has therebetween opposite lower than the speed of impeller
The contact site of movement, floating choma and impeller can mutually be worn under the action of frictional force, if when floating choma serious wear
It will lead to liquid reflux, if impeller damage will lead to impeller performance decline when serious.
Utility model content
When the technical issues of the utility model solves is that existing water pump floating choma is overcome mutually to paste with impeller, cause
The shortcomings that the two mutual frictionally damage, propose the centrifugal pump impeller that can be separated rapidly when a kind of floating choma is pasted with impeller.
The purpose of this utility model can be realized by the following technical scheme: a kind of centrifugal pump impeller, including upper cover and
The center of lower cover, the upper cover is equipped with boss one, and the center of the boss one offers through-hole one, and the upper cap upper surface is equipped with
At least two lug bosses one, are also arranged with the floating choma of activity cooperation on the boss one, the floating choma can with it is convex
It plays one phase of portion to recline, the center of the lower cover is equipped with boss two, and the boss two is interspersed in through-hole one, in the boss two
The heart offers the through-hole two that can be matched with the machine shaft of centrifugal pump, if the one side of the lower cover towards upper cover is equipped with cured leaf
Piece.
At work, this impeller is set in the blade wheel chamber of centrifugal pump and is connected with the indoor reflux lid that absorbs water, work as centrifugation
The floating choma that impeller is equipped with when pump startup can be separated rapidly with impeller and be reclined with reflux lid, and impeller and reflux lid connect
The gap for meeting place reduces, so that the indoor water of impeller is not easy to flow back, the working efficiency of water pump is improved, because floating choma can be fast
Speed is separated with impeller, so that the two is not likely to produce biggish frictional force, reduces the two because the effect of frictional force is mutually worn.
Further, the lug boss is evenly spaced on around the center line of boss one, phase between two neighboring lug boss
Mutually combination forms groove one.Lug boss is evenly spaced on and forms groove to reduce the contact surface of floating choma and impeller
Product, floating choma is separated rapidly when pasting with impeller, the two is not likely to produce biggish frictional force, reduce the two because
The effect of frictional force is mutually worn.
Further, the upper surface of the upper cover is equipped at least two through-holes three, and the blade is equipped with and is interspersed in through-hole
Positioning pin in three, the lower surface of the upper cover be equipped at least two grooves two, and the blade is equipped with to be clamped with groove two
Lug boss two.Through-hole three, positioning pin, groove two and lug boss are set second is that in order to enable upper cover and lower cover to be fitted close, made
Upper cover is consistent with lower cover revolving speed when must be centrifuged pump work, to improve the working efficiency of centrifugal pump.
Further, the upper cover, boss one and lug boss one are integrally formed.Upper cover be integrally formed so that impeller installation,
Convenient disassembly, component are simple with changing.
Further, the lower cover, blade and boss two are integrally formed.Lower cover is integrally formed so that impeller installation, disassembly
Convenient, component is simple with changing.
Compared with the prior art, the advantages of the utility model are: the utility model is equipped with lug boss in upper cap upper surface,
Lug boss is evenly spaced on around the center line of boss one, is combined with each other between two neighboring lug boss and is formed groove one, thus
The contact area for reducing floating choma and impeller enables floating choma to separate rapidly when pasting with impeller, and the two is not easy
Biggish frictional force is generated, both is reduced because the effect of frictional force is mutually worn, while strengthening floating choma and impeller
Service life；Upper cover and lower cover are provided with through-hole three, positioning pin, groove two, so that upper cover and lower cover is enable to be fitted close,
So that upper cover is consistent with the revolving speed of lower cover when centrifugation pump work, to improve the working efficiency of centrifugal pump.
