Abstract
The utility model belongs to the technical field of fluid machinery. In order to solve the lower problem of present vortex pump efficiency, the utility model provides a vortex pump, including main shaft, impeller and leading blade, this leading blade pass through impeller mounting screw in on the main shaft, and lie in the impeller outside, leading blade is oblique flow formula blade, and quantity is 3. The utility model discloses the fluid that vortex pump's the rotatory centrifugal force that forms of leading blade acted on around it is formed with pressurized -water stream, should have pressurized -water stream will destroy the circulatory flow, makes the circulatory flow reduce intensity and weakens, and the outlet pipe is also more approached at the vortex center, link up the proportion that flows among the vortex pump and obtain increasing, link up the intensity that flows and also strengthen thereupon to improved vortex pump's lift and efficiency, noise when having reduced the vortex pump operation has improved the stability of operation, regular vortex pump two kinds of inside flows, reduced to link up flow and the circulatory flow between because of the energy of friction loss.
Description
Technical field
The utility model belongs to the technical field of fluid machinery, is specifically related to a kind of Turo pump.
Background technology
Turo pump belongs to the one of Non-blinding pump, has good not plugging performance, be applicable to pump sewage,Ight soil, fiber and other fluid media (medium)s containing solid particle. As shown in Figure 1, Turo pump comprises suction chamber21,, without phyllocyst 20, outlet pipe 22, impeller 4 and main shaft 3, the blade of impeller 4 is prismatic blade, Turo pumpWhen work, main shaft 3 impeller 4 are rotated, and fluid media (medium) flows into Turo pump from suction chamber 21, and impeller 4 is rightFlow into the fluid media (medium) acting of Turo pump, near the fluid media (medium) outlet 41 of impeller 4 is because of suffered centrifugal forceCompared with forming and connect stream greatly, this perforation stream flows into impeller 4 vane channels from suction chamber 21 and goes out from impeller 4Mouth 41 flows out to without phyllocyst 20, outside outlet pipe 22 excavationg pumps. At the segment fluid flow of impeller 4 near middlesBecause suffered centrifugal force is compared with the little circular flow that forms, this circular flow is without the interior circulation of phyllocyst 20 and form whirlpool,Because circular flow middle part is low-pressure area, the solid particle in fluid tends to circular flow center under the effect of pressure reduction,Then under the drive that connects stream outside efflux pump. In fact, connect stream be Turo pump produce lift main because ofElement, and circular flow is the power that consumes impeller 4 in a sense, the solid particles in fluid obtainsPower most still come from connect stream, thereby circular flow be cause Turo pump efficiency far below common fromThe principal element of heart pump.
Utility model content
In order to solve the lower problem of current Turo pump efficiency, the utility model proposes a kind of Turo pump, to subtractA little less than eliminate even to a certain extent circular flow, and then improve the hydraulic efficiency of Turo pump.
The utility model Turo pump comprises the pump housing, main shaft and impeller, also comprises preposition blade, this preposition bladeBe installed on described main shaft, and be positioned at described impeller outside, described preposition blade is diagonal flow type blade.
Wherein, the quantity of described preposition blade is 2-5.
Wherein, the quantity of described preposition blade is 3.
Wherein, described preposition blade pass is crossed impeller screw and is installed on described main shaft.
Wherein, described main shaft is connected with motor by shaft coupling.
The utility model Turo pump has following beneficial effect:
The centrifugal action that the preposition blade rotary of the utility model Turo pump forms is in its fluid around, frontPut after blade fluid around obtains power and be formed with setting-out stream, this pressure water stream will destroy circular flow, make to followCirculation reduces, and the intensity of circular flow also weakens thereupon; The pressure water stream that preposition blade produces destroys after circular flow,Can increase the energy of fluid media (medium), a part of circular flow is converted into and connect stream, thereby increased in Turo pumpConnect the ratio of stream, the intensity that connects stream is also strengthened thereupon, is that Turo pump produces the main of lift and connect streamFactor, so finally improved eddy flow pump lift and efficiency. Meanwhile, circular flow ratio reduces perforation stream ratioExample increases the noise while also having reduced Turo pump operation, has improved the stability of operation, regular in Turo pumpTwo kinds of portion flow, and have reduced to connect the energy losing because of friction between stream and circular flow. Due to preposition leafSheet is diagonal flow type blade, utilizes the centrifugal action of diagonal flow type blade, and the vortex center of circular flow also has radiallySkew, make circular flow closer to outlet pipe, be conducive to fluid media (medium) in Turo pump to be discharged, certainIn degree, improve flowing of Turo pump internal flow medium.

Detailed description of the invention
Introduce the technical solution of the utility model below in conjunction with accompanying drawing.
The utility model Turo pump comprises the pump housing 1, main shaft 3, impeller 4 and preposition blade 2, and impeller 4 is set withOn main shaft 3, main shaft 3 is arranged in a set of cups 7, and a set of cups 7 is outer to be provided with the filler 6 of preventing water leakage and to haveThe water passage excessively of cooling effect, the right-hand member of main shaft 3 is arranged on thrust bearing 8 and a pair of ball bearing 9, andBe connected with motor (not shown) by shaft coupling. Preposition blade 2 is diagonal flow type blade, and quantity is 2-5Individual, preferably, the quantity of preposition blade 2 is 3. Preposition blade 2 is installed on main shaft 3 by impeller screwGo up, and be positioned at the outside of impeller 4, fluid medium acting together with combining with impeller 4 formation.
Introduce the course of work of the utility model Turo pump below in conjunction with Fig. 2 and Fig. 3, (not shown in the figures by motorGo out) rotate by shaft coupling drive shaft 3, main shaft 3 rotarily drive impeller 4 and preposition blade 2 rotates,Impeller 4 rotates and causes suction chamber 21 to form low-pressure area, and fluid media (medium) is pressed in Turo pump by atmospheric pressure; EnterMost of fluid media (medium) of Turo pump flows into impeller 4 vane channels and flows out to without phyllocyst 20 shapes from impeller 4Become to connect stream 10, this perforation stream 10 is finally by outside outlet pipe 22 excavationg pumps; Another fraction fluid media (medium) existsWithout forming circular flow 11 in phyllocyst 20, this circular flow 11 is positioned at impeller 4 near middles; Preposition blade 2 revolvesTurn the centrifugal action of formation in preposition blade 2 fluid around, preposition blade 2 fluid around obtains meritAfter rate, be formed with setting-out stream, this pressure water stream will destroy circular flow 11, circular flow 11 be reduced, circular flow11 intensity also weakens thereupon; The pressure water stream that preposition blade 2 produces destroys after circular flow 11, can increase streamThe energy of body medium, is converted into a part of circular flow 11 and connects stream 10, connects thereby increased in Turo pumpThe ratio of stream 10, the intensity that connects stream 10 is also strengthened thereupon, is that Turo pump produces lift and connect stream 10Principal element, so finally improved eddy flow pump lift and efficiency.
Because preposition blade 2 is diagonal flow type blade, utilize the centrifugal action of diagonal flow type blade, circular flow 11Vortex center also has skew radially, makes circular flow 11 closer to outlet pipe 22, is conducive to Turo pumpInterior fluid media (medium) is discharged, and has improved to a certain extent flowing of Turo pump internal flow medium. Meanwhile, frontThe quantity of putting blade 2 is 2-5, and negligible amounts can not affect passing through of solid particle in fluid media (medium).
