Abstract
A kind of jet pump guide vane, including inner cover plate and baffle ring, baffle ring setting form the chamber for installing impeller in inner cover plate outer, baffle ring and inner cover plate；Baffle ring outer wall is arranged groove and forms water outlet, is connected by exhalant canal between the chamber on the inside of water outlet and baffle ring, it is characterised in that：The inner cover plate is radially outwardly extending and covers water outlet side, and the position that radially extends of inner cover plate forms baffle, and apopore is arranged on baffle.The utility model provides a kind of jet pump guide vane, drills again after the water outlet of guide vane is closed so that aqueous vapor separation is more thorough, and gas can be easier to be discharged, to promote the suction and self-priming time of jet pump.
Description
Technical field
The utility model belongs to water pump technology, refers in particular to a kind of jet pump and its guide vane.
Background technology
Usually as shown in attached drawing 5-7, outer cover plate, the inner cover plate of outer cover plate and guide vane is arranged in existing jet pump on the outside of guide vane
Between form runner；Centrifugal action of the water through impeller in guide vane is thrown away from the water outlet of guide vane, then by inner cover plate and outer cover plate
Between runner come together outflow to the inlet in the middle part of outer cover plate.
When water pump has just proceeded by self-priming, the water in the air and pump chamber of inlet pipeline is mixed to be discharged through water outlet；
Above structure is flowed since aqueous vapor synchronizes, and aqueous vapor is not readily separated, and extends the self-priming time of pump.
Utility model content
The purpose of this utility model is to provide a kind of jet pump guide vane, drills again after the water outlet of guide vane is closed,
So that aqueous vapor separation is more thorough, gas can be easier to be discharged, to promote the suction and self-priming time of jet pump.
What the purpose of this utility model was realized in：A kind of jet pump guide vane, including inner cover plate and baffle ring, baffle ring setting
In inner cover plate outer, baffle ring and inner cover plate form the chamber for installing impeller；Baffle ring outer wall is arranged groove and forms water outlet, is discharged
It is connected by exhalant canal between chamber on the inside of mouth and baffle ring, it is characterised in that：The inner cover plate is radially outwardly extending and covers out
The position that radially extends of mouth of a river side, inner cover plate forms baffle, and apopore is arranged on baffle.
Wherein, annular mounting groove is arranged around water inlet in the centrally disposed water inlet of the inner cover plate, inner cover plate inside.
Wherein, it is distributed reinforcing rib on the outside of the inner cover plate, reinforcing rib is extended down to baffle, baffle both sides outward by water inlet aperture
The reinforcing rib is distributed with respectively.
Wherein, there are three apopores for distribution on each baffle.
Wherein, the inner cover plate taper evagination, the baffle are burnishing surface.
The utility model additionally provides a kind of jet pump, including jet pipe, impeller, further includes above-mentioned guide vane structure, jet pipe
It is connected on the water inlet on the outside of guide vane, impeller is arranged on the inside of guide vane.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
The outlet of existing guide vane drills again after being closed, in air-water mixture of the electric pump when carrying out self-priming in pump chamber
Water and gas are detached in guide vane water outlet, and since gas density is lighter than the density of water, gas can go out from guide vane water outlet side
It separates, arranges through water outlet, flow velocity of the water due to being slowed down water by resistance, aqueous vapor separation is more thorough, and gas can more hold in water hole
Easily discharge, to promote the suction and self-priming time of jet pump.

Specific implementation mode
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-7：
Embodiment one
A kind of jet pump guide vane, including inner cover plate 1 and baffle ring 4, baffle ring 4 are arranged in 1 outer of inner cover plate, baffle ring 4 and inner cover
Plate 1 forms the chamber of installation impeller 11；4 outer wall of baffle ring is arranged groove and forms water outlet, the chamber of water outlet and 4 inside of baffle ring
Between connected by the exhalant canal 7 of arc, the inner cover plate 1 is radially outwardly extending and covers water outlet side, the radial direction of inner cover plate 1
Extending part forms baffle 5, and three apopores 6 are arranged on baffle 5.
Wherein, annular mounting groove is arranged around water inlet 3 in 1 centrally disposed water inlet 3 of the inner cover plate, 1 inside of inner cover plate
2.Water inlet 3 is for coordinating jet pipe 10, annular mounting groove 2 to be then used to coordinate 11 head construction of impeller.
Wherein, 1 outside of the inner cover plate is distributed reinforcing rib 8, and reinforcing rib 8 is radially outwardly extending to baffle 5, gear by water inlet 3
The reinforcing rib 8 is distributed in 5 both sides of plate respectively.Since the structure eliminates outer cover plate 9, the space setting reinforcing rib 8 reserved carries
The high structural strength of guide vane.
Wherein, 1 taper evagination of the inner cover plate, the baffle 5 are burnishing surface.
Embodiment two
A kind of jet pump, including jet pipe 10, impeller 11, further include the guide vane structure of embodiment one, and jet pipe 10, which is connected to, leads
On water inlet 3 on the outside of leaf, impeller 11 is arranged on the inside of guide vane.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
