Abstract
The invention relates to a double-action vortex pump, which is characterized in that a flow channel is symmetrical flow channel (5), two water inlets (3) are centrally symmetrical relatively to a pump impeller (6), and two water outlets (4) is centrally symmetrical relatively to the pump impeller (6). When the double-action vortex pump works, the forces acting on the pump impeller (6) are equal in intensity and opposite in directions, thus the forces are mutually counteracted, and the shaft and bearing are hardly worn. Therefore, the service lives of the shaft and bearing are longer.
Description
Affiliated technical field
The present invention relates to a kind of double-action Vortex pump, especially almost eliminated the wearing and tearing of axle with bearing.
Background technique
At present, many traditional Vortex pumps of knowing are when fed sheet of a media, and pump impeller receives force unbalance, and shaft strength is also uneven, stressed like Fig. 2.Bearing can receive radial force and rotating shaft friction to take place and wearing and tearing gradually.Therefore, its working life can be very not long yet.
Summary of the invention
Receive radial imbalance force and rotating shaft that friction takes place and the deficiency of wearing and tearing gradually in order to overcome existing Vortex pump bearing, the stressed symmetry of pump impeller of the present invention, equal and opposite in direction, in the opposite direction, cancel out each other, and solved the wear-resisting problem of bearing, force analysis such as Fig. 5.
The technical solution adopted for the present invention to solve the technical problems is: cover in the intake end cover of existing Vortex pump and waterexit end and respectively done two axisymmetric runners, centrosymmetric two water intakes and centrosymmetric two water outlets.
The invention has the beneficial effects as follows, solved the wear-resisting problem of bearing, prolonged long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural diagrams intention of existing peripheral pump.
Fig. 2 is the diagram that existing peripheral pump bearing receives unbalanced force.
Fig. 3 structural drawing of the present invention.
Fig. 4 is that the A-A of Fig. 3 is to sectional view.
Fig. 5 is the diagram that peripheral pump bearing of the present invention receives the symmetric force balance.
Among the figure, 1. intake end cover, 2. water outlet end cap, 3. water intake, 4. water outlet, 5. balance runner, 6. pump impeller, 7. rotating shaft, 8. bearing.
Embodiment
In Fig. 3, Fig. 4, under rotating shaft (7) drove, pump impeller (6) can freely rotate in the cavity of intake end cover (1) and water outlet end cap (2) formation, and bearing (8) supports water outlet end cap (2); The cavity that pump impeller (6), intake end cover (1) and water outlet end cap (2) form is balance runner (5); Two water intakes (3) are about pump impeller (6) center symmetry; Two water outlets (4) are about pump impeller (6) center symmetry.
During work, the dual force in the balance runner (5) is as shown in Figure 5, and this amount of force is equal, and is in the opposite direction, acts on the pump impeller (6) and just cancels out each other.
Claims (3)
1. a double-action Vortex pump is made up of intake end cover (1), water outlet end cap (2), pump impeller (6), and its intake end cover (1) and water outlet end cap (2) respectively have two balance runners (5), and two balance runners (5) distribute axisymmetricly.
2. a kind of double-action Vortex pump according to claim 1, its intake end cover (1) has two water intakes (3), and two water intakes (3) distribution that is centrosymmetric; Its water outlet end cap (2) has two water outlets (4), and two water outlets (4) distribution that also is centrosymmetric.
3. a kind of double-action Vortex pump according to claim 1; Intake end cover (1) has two water intakes (3), two water outlets (4) and two runner (5) axisymmetricly; The distribution that is centrosymmetric of its two water intakes (3), two water outlets (4) distribution that also is centrosymmetric; Its water outlet end cap (2) has two runners (5) axisymmetricly, no water outlet (4).
