Abstract
Centrifugal pump with propeller, centrifugal pump has centrifugal impeller, and one end of impeller, which has, sealing unit on axle, axle, and the other end of impeller has water inlet, there is propeller in water inlet, and impeller is coaxial with propeller.Propeller is without axis, and centre is empty, and it is cylindrical that it promotes blade to be fixed on, in the water inlet of impeller, promotes blade and impeller into being rigidly connected.The method of centrifugal pump with propeller, drives propeller synchronous rotary when impeller rotates, water is promoted by two-stage thrust augmentation, the first order is that the blade that propeller is rotates in water, revolving force is converted into propulsive force, the blade of propeller constantly promotes water to the water inlet of impeller, and thrust direction is parallel with axle；The water that the second level enters after impeller is accelerated to release again by the centrifugal force of impeller, and thrust direction is the tangential direction of circumference of impeller.Efficiency can be improved, increases flow, lift is improved.
Description
Technical field
The invention belongs to a kind of centrifugal pump with propeller, the characteristic promoted with water by two-stage thrust augmentation is also a kind of increasing
The centrifugal pump of die mould.
Background technology
Existing centrifugal pump only reaches the purpose drawn water, Chinese Patent Application No. with centrifugal impeller mostly：
201480072887.3《Self-priming centrifugal pump》, including：The first housing parts with the antetheca with entrance, with outlet
Two housing parts, the impeller being rotatably disposed within the second housing parts, and pump screw rod, it is rotatably disposed within first
In housing parts, impeller is connected to and including centerbody, helical blade arranges exist for being fed to impeller around centerbody
Any gas in liquid, wherein, centerbody is arranged in from a certain distance from the sidepiece towards the antetheca of centerbody so that tool
There is the passage formation of at least 12mm width in centerbody and towards between the sidepiece of the antetheca of centerbody.Chinese patent application
Number：201510608741.2《A kind of helico-centrifugal pump》, helical blade is connected with the pump shaft of pump housing water inlet, in water outlet
Pump body on the outside of centrifugal impeller, helical blade is housed at mouthful on following pump shaft abrasive rubber set is housed.This two patents
Apply for one helical blade of arranged in front in impeller, pump screw rod is coaxially arranged with impeller, except there is self-priming, and also
The efficiency of pump can further be improved.
In order to further improve the series of centrifugal pump, the present invention provides a kind of centrifugal pump with propeller, with water by two
The characteristic that level reinforcing is promoted.
The technical solution adopted for the present invention to solve the technical problems is：Centrifugal pump with propeller, centrifugal pump has centrifugation
Impeller, one end of impeller, which has, sealing unit on axle, axle, the other end of impeller has water inlet, has spiral in water inlet
Oar, impeller is coaxial with propeller.Propeller is without axis, and centre is empty, and it is cylindrical that it promotes blade to be fixed on, in impeller
Water inlet, promotes blade and impeller into being rigidly connected.
The method of centrifugal pump with propeller, drives propeller synchronous rotary when impeller rotates, water is promoted by two-stage thrust augmentation,
The first order is that the blade that propeller is rotates in water, revolving force is converted into propulsive force, the blade of propeller is constantly to leaf
The water inlet of wheel promotes water, and thrust direction is parallel with axle；The second level is that the water entered after impeller is accelerated by the centrifugal force of impeller again
Release, thrust direction is the tangential direction of circumference of impeller.
The beneficial effects of the invention are as follows, the centrifugal pump with propeller, centrifugal pump has centrifugal impeller, and there is axle one end of impeller,
There is sealing unit on axle, the other end of impeller has water inlet, there is propeller in water inlet, impeller is coaxial with propeller
's.Propeller is without axis, and centre is empty, and it is cylindrical that it promotes blade to be fixed on, in the water inlet of impeller, promotes blade and impeller
Into being rigidly connected.The method of centrifugal pump with propeller, drives propeller synchronous rotary when impeller rotates, water is pushed away by two-stage thrust augmentation
Dynamic, the first order is that the blade that propeller is rotate in water, and revolving force is converted into propulsive force, the blade of propeller it is continuous to
The water inlet of impeller promotes water, and thrust direction is parallel with axle；The water that the second level enters after impeller is accelerated by the centrifugal force of impeller again
Release, thrust direction is the tangential direction of circumference of impeller.Efficiency can be improved, increases flow, lift is improved.
The present invention is further described with reference to the accompanying drawings and examples for brief description of the drawings.
Centrifugal impeller schematic diagrames of the Fig. 1 with propeller.
Centrifugal impeller decomposing schematic representations of the Fig. 2 with propeller.
In figure in 1 and Fig. 2,1. impellers, 2. axles, 3. sealing units, 4. propellers.
Embodiment：The structure of centrifugal pump with propeller, has impeller 1, one end of impeller 1, which has on axle 2, axle 2, has axle close
Unit 3 is sealed, the other end of impeller 1 has water inlet, there is propeller 4 in water inlet.Propeller 4 is without axis, and it promotes blade to consolidate
Be scheduled on it is cylindrical, in the water inlet of impeller 1, with impeller 1 into being rigidly connected.The blade of propeller 4 can be two to six.
The method of work of centrifugal pump with propeller, the blade that propeller 4 is is rotated in air or water, and motor is turned
Dynamic power is converted into propulsive force, and propeller 4 is as screw propeller principle peculiar to vessel, but structure is different, does not take turns
It is empty in the middle of hub, is conducive to water to flow into the water inlet of impeller 1.The synchronous rotary of propeller 4 is driven when impeller 1 rotates, water is by two
Level reinforcing is promoted.The first order is that the blade of propeller 4 constantly promotes water to the water inlet of impeller 1, and the second level is to enter impeller 1
Water afterwards is accelerated to release by the centrifugal force of impeller 1 again, so it is also a kind of centrifugal pump of boosting type.
