Abstract
The utility model discloses a reposition of redundant personnel centrifugal pump, including the pump body, set up the inside impeller of the pump body, with impeller connection and drive the rotatory pivot of impeller and with the feed inlet and the discharge gate of the inside intercommunication of the pump body, be equipped with on the blade of impeller the inside suction hole of the intercommunication pump body and with the suction channel of suction hole intercommunication, the axle center position of pivot be equipped with the outside venthole of the intercommunication pump body and with the air outlet channel of venthole intercommunication, suction channel and air outlet channel intercommunication. The utility model discloses a gaseous the inhale suction channel of reposition of redundant personnel centrifugal pump through setting up suction hole on the impeller and containing the area in with the ground paste to it is outside to arrange the pump body through air outlet channel and venthole, makes the gas separation in the ground paste go out, thereby has reduced the gas content in the ground paste effectively, has reduced the condition of impeller idle running simultaneously, has improved the work efficiency of centrifugal pump, and has practiced thrift the energy, and the delivery pressure of centrifugal pump also can reach perfect condition.
Description
Technical field
This utility model relates to pump technology field, shunts centrifugal pump particularly to one.
Background technology
Centrifugal pump is a kind of pump housing utilizing impeller to rotate and to make fluid generation centrifugal motion carry out work, wherein impeller and rotating shaft are the core components of centrifugal pump, its impeller of current centrifugal pump itself does not has suction capacity when idle running, the surrounding of impeller must be allowed in advance to be full of fluid, and impeller just can pump slip when rotating.But this working method commonly there is a problem in that so that flow significantly reduces, the conveying efficiency of centrifugal pump is difficult to effectively play owing to causing impeller to dally containing the large percentage of band gas in slip, time-consuming take electricity；Additionally, a large amount of gases containing band also can make output pressure be difficult to reach perfect condition in slip.
Utility model content
For solving above-mentioned technical problem, the utility model discloses a kind of shunting centrifugal pump, including the pump housing, it is arranged on the impeller of described pump body is connected and impeller rotates rotating shaft and the charging aperture connected with described pump body and discharging opening with described impeller, the suction hole being communicated with described pump body on the blade of described impeller and the air intake passage connected with described suction hole, the shaft core position of described rotating shaft is communicated with the venthole outside the described pump housing and the outlet passageway connected with described venthole, and described air intake passage connects with described outlet passageway.
As further improvement of the utility model, described impeller back is provided with protective plate.
As further improvement of the utility model, it is tightly connected by mechanical seal case between described rotating shaft and the pump housing.
As further improvement of the utility model, described rotating shaft one end is provided with lubricant reservoir, and described lubricant reservoir is connected with described axis of rotation by bearing.
As further improvement of the utility model, the described pump housing and impeller are made up of wear resistant cast iron.
The beneficial effects of the utility model are:
Shunting centrifugal pump of the present utility model will suck air intake passage containing the gas carried in slip by the suction hole being arranged on impeller, and it is discharged to outside the pump housing through outlet passageway and venthole, the gas in slip is made to separate, thus significantly reduce the gas content in slip, decrease the situation of impeller idle running simultaneously, improve the work efficiency of centrifugal pump, and saved the energy, the output pressure of centrifugal pump also is able to reach perfect condition.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, the accompanying drawing used required in embodiment will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structure sectional view of the present utility model.
Labelling in figure: the 1-pump housing；2-impeller；21-suction hole；22-air intake passage；3-rotating shaft；31-venthole；32-outlet passageway；4-charging aperture；5-discharging opening；6-protective plate；7-mechanical seal case；8-lubricant reservoir；9-bearing.
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 clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.
As it is shown in figure 1, a kind of shunting centrifugal pump, including the pump housing 1, it is arranged on the impeller 2 within the pump housing 1 is connected and impeller 2 rotates rotating shaft 3 and the charging aperture 4 that connect internal with the pump housing 1 and discharging opening 5 with impeller 2；In order to improve the anti-wear performance of this centrifugal pump, the pump housing 1 and impeller 2 select wear resistant cast iron to make.
Being communicated with the suction hole 21 within the pump housing 1 and the air intake passage 22 connected with suction hole 21 on the blade of impeller 2, the shaft core position of rotating shaft 3 is communicated with the venthole 31 outside the pump housing 1 and the outlet passageway 32 connected with venthole 31；Air intake passage 21 connects with outlet passageway 31, makes suction hole 21, air intake passage 22, outlet passageway 32 and venthole 31 form the gas passage inside and outside a connection pump housing 1.
Impeller 2 back is provided with protective plate 6, is tightly connected by mechanical seal case 7 between rotating shaft 3 and the pump housing 1, and rotating shaft 3 one end is provided with lubricant reservoir 8, and lubricant reservoir 8 is rotationally connected with rotating shaft 3 by bearing 9, is lubricated for countershaft 3.
During utility model works, air extractor is coordinated to bleed from venthole 31, so will produce negative pressure in air intake passage 21 and outlet passageway 31, thus produce suction force, make suction hole 21 be discharged by the gas within the pump housing 1, reduce the gas content in slip, decrease the situation of impeller idle running simultaneously, improve the work efficiency of centrifugal pump, and saved the energy, the output pressure of centrifugal pump also is able to reach perfect condition.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
