Abstract
Between assembled guide vane formula pump, including water pump vane, radial guide vane, impeller, there is a space guide vane body after radial guide vane, there is a ring-like runner in space guide vane body, there is spatial guide blade in runner, the entry design of spatial guide blade is matched with radial vane outlet liquid stream.Sealing ring is provided between impeller and space guide vane body, sealing ring is fixed in space guide vane body, and Material Strength and hardness are lower than impeller.The present invention can be such that impeller and space guide vane body is not directly contacted with, and allow between impeller and sealing ring and rub, and sealing ring friction destruction due to intensity and hardness are lower is replaced, to protect the service life of impeller and space guide vane body.
Description
Technical field
The invention belongs to water pump technology, in particular to a kind of assembled guide vane formula pump.
Background technique
Guide vane is a kind of important pattern of water pump pumping chamber, there is very universal application in water pump.Common sectional type is more
Grade pump, long-shaft pump, spatial guide blade formula centrifugal pump, diagonal pumps, well pump, axial-flow pump mostly use greatly guide-vane pumping chamber.It is existing to lead
Leaf is divided into radial vane and spatial guide blade.It is directly connected to as the front and back guide blade that flow channel type guide blade is actually radial vane,
Individual small flow channels are formed, the medium of each runner after positive guide vane does not mix mutually.Radial vane, including flow channel type guide blade, lead
Medium in leaf is radially flowed out from one stage impeller outlet, and radial inflow next stage impeller, and axial distance is short, is mainly used for segment
Formula centrifugal pump can reduce axial length because axial distance is short, improve rotor rigidity, but equally also because axial distance is short, from
Turning radius when guide vane flows to return guide vane is small, and turn curvature is big, and parthydraulic loss is big, and pump efficiency is by very big shadow
It rings.Spatial guide blade, because of structure problem, mouthpiece's cross-sectional area of spatial guide blade is larger, is not suitable for the design of low specific speed pump, institute
With our existing long-shaft pumps, spatial guide blade formula centrifugal pump, well pump using spatial guide blade without lower specific speed, that is,
It says, under same flow and revolving speed, water pump single-stage lift is lower, same lift, needs compared to sectional multi-stage centrifugal pump
More impeller progressions are high-specific speed pump as diagonal pumps and axial-flow pump in itself.
Summary of the invention
The present invention is intended to provide a kind of assembled guide vane formula pump, overcomes the shortcoming of above-mentioned prior art.
Technical solution of the present invention:
Assembled guide vane formula pump, including close between water pump vane, radial guide vane, space guide vane body and impeller and space guide vane body
Seal ring has a space guide vane body after radial guide vane, has a ring-like runner in space guide vane body, have space to lead in runner
Leaf, medium from water pump vane come out after, subsequently enter radial guide vane and space guide vane body, the spatial guide blade in space guide vane body
Entry design and radial vane outlet liquid stream match.In this way, impeller and space guide vane body can be made to be not directly contacted with, and allow leaf
It rubs between wheel and sealing ring, sealing ring friction destruction due to intensity and hardness are lower is replaced, to protect impeller and space
The service life of diffuser.
Further, sealing ring is set between impeller and space guide vane body, sealing ring is fixed in space guide vane body,
Material Strength and hardness are lower than impeller.In this way, this assembled guide vane formula can be made to pump, both there is segmental centrifugal pump to lead compared to space
Blade type centrifugal pumps the higher feature of single-stage lift, and the design feature with spatial guide blade formula pump, and can axially intake axial water outlet,
Well pump or other wet pit pump configurations may be fabricated to.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Shown in Fig. 5, assembled guide vane formula pump, including water pump vane (1), radial guide vane (2), space guide vane body (6) and sky
Between sealing ring (5) between diffuser (6) and impeller (1).The impeller (1) be rotary part, promoted medium energy, medium from
After the impeller (1) comes out, the radial guide vane (2) is first passed through, is gone out using the space guide vane body (6).It leads in space
There is a ring-like runner on leaf body (6), have in runner spatial guide blade (7), spatial guide blade (7) can will go out from radial vane (2)
The slipstream quick-action of the medium come can be changed into pressure energy, the entry design and radial guiding of the spatial guide blade in space guide vane body
Leaf exports liquid stream matching.After being come out due to medium from the impeller (1), the first excessively described radial guide vane (2), the larynx of pumping chamber
Tongue is the same with segmental centrifugal pump in the radial vane (2) entrance, so the hydraulic performance of water pump is also and segmental centrifugal pump
Equally, it can be designed as low specific speed pump, i.e., under identical flow and revolving speed, single-stage impeller lift is than existing spatial guide blade
Long-shaft pump, spatial guide blade formula centrifugal pump, the well pump of formula etc. are much higher.Medium after radial guide vane (2) using space by leading
Leaf body (6), the spatial guide blade (7) in space guide vane body (6) compares the radial return guide vane (3) of sectional type multi-stage pump, axial long
Spend longer, turning radius is big, curvature is small, can reduce the local resistance at turning, water pump hydraulic efficiency is promoted, moreover, this group
Close guide-vane pump have spatial guide blade formula pump design feature, can axially intake axial water outlet, may be fabricated to well pump or other
Wet pit pump configuration.
In addition, being provided with sealing ring (5), the sealing ring between the impeller (1) and the space guide vane body (6)
(5) it is fixed on the space guide vane body (6), impeller and space guide vane body can be made to be not directly contacted with, the sealing ring (5)
Material Strength and hardness are lower than the impeller (1), described close when being rubbed between the impeller (1) and the sealing ring (5)
Seal ring (5) friction destruction due to intensity and hardness are lower is replaced, to protect the impeller (1) and the space guide vane body (6)
Service life.
