Background technique
At present, the balanced controls of Balance disc, gimbal, balance set or balancing drum and so on mostly are set in traditional sections multistage centrifugal oil pump, are used for the suffered axial force of balance pump shaft, but it is bigger often to remain axial force, so that balanced controls damage, and then reduce the reliability of pump.
The model utility content
The technical problems to be solved in the utility model just is: at the technical problem that prior art exists, the utility model provides the horizontal pumping installations of self balancing sections of a kind of simple and compact for structure, with low cost, good reliability, long service life.
For solving the problems of the technologies described above, the utility model by the following technical solutions.
The horizontal pumping installations of a kind of self balancing sections, comprise motor, the pump shaft and the pump housing, one end of described pump shaft is arranged in the pump housing, the other end of described pump shaft links to each other with the output terminal of motor, offer medium access interface and medium pump outbound port on the described pump housing, it is characterized in that: be separated into independently first separately joint pumping chamber and partial node pumping chamber in the cavity of the described pump housing, the entry end in described first joint pumping chamber is connected with the medium access interface, the head in described first joint pumping chamber saves the pumping outlet and is connected by the entry end of transition tube with partial node pumping chamber, and the outlet end in described partial node pumping chamber is communicated with the medium pump outbound port; Described pump shaft is positioned on a section of first joint pumping chamber and is arranged with first joint guide vane wheel, and described pump shaft is positioned on a section of partial node pumping chamber and is arranged with the partial node guide vane wheel, and the working surface that described head saves guide vane wheel and partial node guide vane wheel is towards on the contrary.
As further improvement of the utility model:
Described first joint pumping chamber and partial node pumping chamber are separated by the orifice sleeve that is sheathed on the pump shaft.
Described medium pump outbound port and first joint pumping outlet are one-body molded.
Compared with prior art, advantage of the present utility model just is: the horizontal pumping installations of self balancing sections of the present utility model, simple and compact for structure, with low cost, good reliability, by save guide vane wheel and partial node guide vane wheel towards opposite head, form opposite axial force at work, thereby reach the effect of balance pump shaft axial force, prolonged the working life of pump shaft greatly.

Embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, the horizontal pumping installations of self balancing sections of the present utility model, comprise motor 1, the pump shaft 2 and the pump housing 3, one end of pump shaft 2 is arranged in the pump housing 3, the other end of pump shaft 2 links to each other by the output terminal of coupling with motor 1, offer medium access interface 33 and medium pump outbound port 34 on the pump housing 3, be separated into independently first separately joint pumping chamber 31 and partial node pumping chamber 32 in the cavity of the pump housing 3, the entry end in first joint pumping chamber 31 is connected with medium access interface 33, the head in first joint pumping chamber 31 saves pumping outlet 311 and is connected by the entry end of transition tube 4 with partial node pumping chamber 32, and the outlet end in partial node pumping chamber 32 is communicated with medium pump outbound port 34.Pump shaft 2 is arranged in first joint pumping chamber 31 and the partial node pumping chamber 32 successively, and first joint pumping chamber 31 and partial node pumping chamber 32 are separated by the orifice sleeve 21 that is sheathed on the pump shaft 2.Be arranged with first joint guide vane wheel 312 on the pump shaft 2 in head saves pumping chamber 31, be arranged with partial node guide vane wheel 321 on the pump shaft 2 in partial node pumping chamber 32, the working surface of first joint guide vane wheel 312 and partial node guide vane wheel 321 is towards on the contrary, be symmetric arrangement and quantity unanimity, pump shaft 2 be sheathed on that head on the pump shaft 2 saves guide vane wheel 312 and partial node guide vane wheel 321 is formed rotor part in the lump.In the present embodiment, the single piece that medium pump outbound port 34 is formed in one, chamber, its underpart is saved pumping and is exported 311 for saving head that pumping chamber 31 links to each other with head, and its upper chambers is communicated with partial node pumping chamber 32, and upper chambers and lower chamber are cavity independently separately.
Working principle: under the driving of motor 1, the head that pump shaft 2 drives on it saves guide vane wheel 312 and 321 rotations of partial node guide vane wheel, medium sucks from medium access interface 33, enter first joint pumping chamber 31, save at head under the promotion of guide vane wheel 312, save pumping outlet 311 from head and deliver to partial node pumping chamber 32 through transition tube 4; Move under the promotion of partial node guide vane wheel 321, medium is finished the last stack of energy in partial node pumping chamber 32, and final medium will pump from medium pump outbound port 34.In whole process, medium will produce the forward axial force when saving guide vane wheel 312 through head, because the working surface of first joint guide vane wheel 312 and partial node guide vane wheel 321 is towards on the contrary, to produce reverse axial force during medium process partial node guide vane wheel 321, two axial forces are equal and opposite in direction in theory, direction is opposite, and the whole axial force that then acts on the pump shaft 2 is zero.
