Description
Technical field
This utility model relates to wake offset-type front guide impeller.
Background technology
Preposition guide wheel of prewhirling mainly is made up of conduit and stator, is arranged on the nearby side of propeller, and conduit produces additional pushing away
Power, built-in stator produce favourable preswirl, reduce the loss of screw current rotating energy.Some guide wheel is annular, some
It is provided with breach, but is provided with the guide wheel of breach, collide the most unavoidably.
Summary of the invention
Before the purpose of this utility model is to provide a kind of simple in construction, wake offset-type reasonable in design, easy to use
Put guide wheel, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme, and wake offset-type front guide impeller, including leading
Pipe, one group of stator, conduit is provided with opening, and catheter opening edge is provided with protection set, is provided with a stator at conduit right openings,
Remaining stator is arranged on the pipe inner wall that conduit axle center is on the lower side, and the axle center that stator is formed is offset to the top in conduit axle center, leads
Leaf has five, and stator is made up of the first deflector and the second deflector, and the thickness of the first deflector is the second deflector thickness
Twice.
Further improvement of the utility model is: the first deflector is directly connected with pipe inner wall, the second deflector
/ 2nd of a length of first deflector.
Further improvement of the utility model is: on the left of conduit, the stator length of opening part is shorter than remaining stator.
Further improvement of the utility model is: on the left of conduit the three of the stator of opening part remaining stator length a length of
/ mono-.
In this structure, conduit is provided with opening, and catheter opening edge is provided with protection set, and protection set serves the work of buffering
With, stator is made up of the first deflector and the second deflector, and the thickness of the first deflector is the twice of the second deflector thickness, with
The deflector that a conventional monoblock thickness is identical is compared, and serves the effect of shunting.
Compared with prior art, the beneficial effects of the utility model are:
This utility model utilizes accelerating type conduit to produce additional thrust, built-in stator produces favourable preswirl, reduces spiral shell
Rotation oar wake flow rotating energy loss, make propeller enters stream interface evenly, is conducive to improving propeller efficiency, improves stern flowing
Separate, recover stern hull surface pressure, reduce energy resource consumption, improve economic benefit, after preposition guide wheel of prewhirling is installed, permissible
Save the fuel oil of 4%～8%.
Accompanying drawing explanation

Fig. 2 is the structural representation of stator；
Label in figure: 1-conduit, 2-stator, 3-opening, 4-protect set, 5-the first deflector, 6-the second deflector.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole realities
Execute example.Based on the embodiment in this utility model, those of ordinary skill in the art are institute under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: wake offset-type front guide impeller, including conduit 1,
One group of stator 2, conduit 1 is provided with opening 3, and conduit 1 opening 3 edge is provided with protection set 4, is provided with one at conduit 1 right openings 3
Stator 2, remaining stator 2 is arranged on conduit 1 inwall that conduit 1 axle center is on the lower side, and the axle center that stator 2 is formed is offset to conduit 1 axle
The top of the heart, stator 2 has five, and stator 2 is made up of the first deflector 5 and the second deflector 6, and the thickness of the first deflector 5 is
The twice of the second deflector 6 thickness.
Further improvement of the utility model is: the first deflector 5 is directly connected with conduit 1 inwall, the second deflector 6
A length of first deflector 5 1/2nd.
Further improvement of the utility model is: on the left of conduit 1, stator 2 length at opening 3 is wanted than remaining stator 2
Short.
Further improvement of the utility model is: stator 2 remaining stator 2 length a length of at opening 3 on the left of conduit 1
1/3rd.
This utility model utilizes accelerating type conduit to produce additional thrust, built-in stator produces favourable preswirl, reduces spiral shell
Rotation oar wake flow rotating energy loss, make propeller enters stream interface evenly, is conducive to improving propeller efficiency, improves stern flowing
Separate, recover stern hull surface pressure, reduce energy resource consumption, improve economic benefit, after preposition guide wheel of prewhirling is installed, permissible
Save the fuel oil of 4%～8%.
The foregoing is only explanation embodiment of the present utility model, be not limited to this utility model, for ability
For the technical staff in territory, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement made
Deng, within should be included in protection domain of the present utility model.
