Description
Technical field
The utility model is related to a kind of impeller of pump more particularly to a kind of diving impeller of pump.
Background technology
Deep-well is the capital equipment for extracting deep-well underground water with immersible pump, is widely used in field irrigation and sprinkling irrigation.For
For deep-well immersible pump, single-stage lift is to weigh one of the important index of pump performance.Its higher overall length of monopole lift
It is smaller, overall volume is smaller, occupies less space, improves economy, be also convenient for transport use.
But existing deep-well immersible pump is by hole diameter due to being limited, the list of deep-well immersible pump under same traffic
Pole lift is lower than Ordinary Centrifugal Pumps.The performance of existing deep-well immersible pump is relatively low, to improve single-stage lift, needs sacrificial body
Product, but affect the application of deep-well immersible pump.
Invention content
A kind of diving impeller of pump is provided utility model aims to solve the above problem of the existing technology,
Under the premise of given volume, single-stage lift can be improved, when being applied to deep-well immersible pump, that is, there is suitable volume, again
The hydraulic efficiency of pump can be improved.
What the above-mentioned technical purpose of the utility model mainly solved by the following technical programs：Diving impeller of pump, packet
Front shroud, back shroud are included, the blade being set between front shroud, back shroud has integrally formed shaft on the back shroud,
There is axis hole, the blade to be integrally formed on cover board in the rear, the inner end of the blade and the shaft in the shaft
Outer wall is relative to setting, it is characterised in that the outer end face that the blade is is vertical with the front shroud, and is located at the front shroud
Outer institute is in the plane.Under the premise of given volume, single-stage lift can be improved, when being applied to deep-well immersible pump, that is, is had
There is suitable volume, and the hydraulic efficiency of pump can be improved.Specifically, blade extends to the outer of front shroud, increases leaf
The effective area of piece improves single-stage lift under the premise of not increasing impeller volume.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures：It is described
The quantity of blade is 7-8 pieces.The quantity of blade is relatively more, is also beneficial to increase single-stage lift, further improves impeller
Energy.
The thickness of the blade is 1.8 ~ 1.9mm.The thickness of blade is relatively thin so that the space between blade and blade
It is more, it is also beneficial to improve single-stage lift.
The diameter of the back shroud is less than the diameter of the front shroud.
On the back shroud have auxiliary section, the quantity of the auxiliary section is equal with the quantity of blade, the auxiliary section with
The corresponding blade cooperation, makes to form arc chord angle between the back shroud outer and the blade.
The groove of the middle part setting taper type of the back shroud, the groove is interior to be arranged plural pieces back blades, the accessory lobes
Piece be centrosymmetric emitting shape distribution.
The utility model has the advantage that：1, under the premise of given volume, single-stage lift can be improved, is applied to
When deep-well immersible pump, that is, there is suitable volume, and the hydraulic efficiency of pump can be improved.Specifically, before blade extends to
The outer of cover board increases the effective area of blade, under the premise of not increasing impeller volume, improves single-stage lift.2, leaf
The quantity of piece is relatively more, is also beneficial to increase single-stage lift, further improves impeller performance.3, the thickness of blade is relatively
It is thin so that the space between blade and blade is more, is also beneficial to improve single-stage lift.
