The model utility content
It is reliable that technical problem to be solved in the utility model provides a kind of sealing, stable, and the energy-efficient nothing that energy consumption is low is leaked vertical self-sucking pump.
In order to solve the problems of the technologies described above, the energy-efficient nothing that the utility model provides is leaked vertical self-sucking pump, comprise motor, the pump housing, pump cover, efficient impeller, sub-propeller, stator, pump shaft and motor cabinet, the described pump housing by level near main cylinder and secondary cylindrical shell form, described secondary cylindrical shell and described main cylinder bottom communicate, the outlet pipe that transfers level after described main cylinder top is provided with and tilts to rise earlier to, described impeller, stator, pump cover is located in the described main cylinder, be provided with outlet bend pipe vertically upward in the described secondary cylindrical shell, the open height that goes out of described bend pipe is higher than described impeller.
Described sub-propeller upper end is provided with oil sealing.Described pump shaft is connected with the rotating shaft of motor by coupling.The top that connecting tube entangles described pump shaft and described connecting tube is connected on the described motor cabinet, and the bottom is connected on the described stator.Described sub-propeller is the minor diameter sub-propeller.Impeller by the gap step-down, is joined the minor diameter sub-propeller for band increasing back sealing ring structure.Described impeller has adopted not only efficiently but also the anti-cavitation performance design.
Adopt the energy-efficient nothing of technique scheme to leak vertical self-sucking pump, its advantage is: (1), pump water inlet and outlet pipe all are level, line arrangement reduces by 2 90 ° of elbows than prior art self-priming pump, can improve water pump and inhale 0.5～0.8 meter of journey, reduce by 1～1.5 meter of pipe resistance, improved unit efficiency.(2), impeller is for band increasing back sealing ring structure, by the gap step-down, can significantly reduce the sub-propeller sealing load, thereby reduce the sub-propeller diameter, improves pump efficiency.(3), motor coupler is connected with the motor shaft interference, pump shaft and motor coupler are rigidly connected by flange, concentricity is guaranteed, the water pump operation reliability improves greatly.(4), sub-propeller and oil sealing two seals, not only can guarantee operation and shut down does not instantaneously all have leakage, and the air outside can not sucking during self-priming, self-priming time significantly shortens.(5), water pump vane has adopted the design that improves anti-cavitation performance, water pump suction journey height.
In sum, the utility model is that a kind of sealing is reliable, and stable, energy consumption is low and simple in structure, reliable performance, easily manufactured energy-efficient nothing are leaked vertical self-sucking pump.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, motor 1 is fixed on the motor cabinet 2, motor cabinet 2 links to each other with the pump housing 6, the rotating shaft of motor 1 links to each other by motor coupler 7 and pump shaft 9, pump shaft 9 is equipped with oil sealing 3 from top to bottom successively, sub-propeller 8 and impeller 10, pump cover 11 is on the intermediate clapboard 64 of main cylinder 61, impeller 10 is covered with stator 5, stator 5 is fixed on the pump cover 11, the top that connecting tube 4 entangles pump shaft 9 and connecting tube 4 is connected on the motor cabinet 2, the bottom is connected on the stator 5, and sub-propeller 8 is the minor diameter sub-propeller, and impeller 10 is band increasing back sealing ring structure, by the gap step-down, the general centrifugal pump of impeller 10 inlet diameters is big, adopted not only efficiently but also the anti-cavitation performance design, the pump housing 6 by level near main cylinder 61 and secondary cylindrical shell 62 form, secondary cylindrical shell 62 and main cylinder 61 bottoms communicate, main cylinder 61 tops have and are tilted to the outlet pipe 63 that afterwards transfers level to earlier, are provided with outlet bend pipe 12 vertically upward in the secondary cylindrical shell 62, and the open height that goes out of bend pipe 12 is higher than impeller 10.
Referring to Fig. 2, the working procedure that this energy-efficient nothing is leaked vertical self-sucking pump is as follows;
Fill liquid in the pump housing 6 when starting first, impeller 10 is high speed rotating under the driving of motor 1, because action of centrifugal force, the liquid in the pump housing 6 is thrown out of impeller 10 outlets, and impeller 10 inlets produce vacuum like this.Air in the intake pipe 12 enters impeller 10, forms gas-liquid mixture between the very little gap of impeller 10 and stator 5.Gas-liquid mixture slows down by the extremely short diffusion admittance of stator 5, is discharged to the enough big pump housing of volume 6 tops.Because air and density of liquid difference are very big, overflow the water surface so be distributed in just floating poly-the moving up of the bubble of current inside, and discharge from water pump outlet pipe 63.Liquid mixes with gas owing to the reason of self gravitation and impeller 10 import negative-pressure suckings comes back to impeller 10 outer rims, along with whole process goes on again and again, gas constantly is drawn out of in the bend pipe 12, therefore relative vacuum appears, water level in the pipeline is just along with rising, till gas is all drained, finish the self-priming process after, turning to transfusion operation automatically.After water pump is shut down, the liquid in the bend pipe 12 since siphonage reflux, but since in the secondary cylindrical shell 62 vertically upward bend pipe 12 certain height is arranged, after siphonage stopped, remaining liquid had still flooded impeller 10, guaranteed that start next time to need not fluid injection.
Personnel in the present technique field should be realized that, the foregoing description is not with this novel qualification of opposing, as long as in this novel connotation scope, any the foregoing description technique variation, flexible program are not all exceeded protection domain of the present utility model.
