Abstract
A micro-pressure meandering sealing energy-saving pump can reduce inner leakage and enhance the water pump efficiency. A shaft sealing device of the pump is composed of a floating ball level water compensator arranged on the top of a pump cover, a shaft sealing water supply pipeline and a meandering type machine seal, the energy-saving pump can reduce inner leakage of the shaft seal, and can enhance the service life of the shaft sealing device; simultaneously, the fixing sealing surface of the impeller sealing ring adopting meandering type full-ring axial direction fixing sealing can reduce the inner leakage of the impeller and enhance energy-saving effect.
Description
Affiliated technical field
The utility model relates to a kind of energy-saving water pump, especially the plumbing pump.
Background technique
At present, known centrifugal water pump shaft sealing all is by water channel the pump chamber high pressure water directly to be caused shaft sealing chamber to carry out water-stop by filler or mechanical seal.The packing seal frictional resistance is big, and mechanical efficiency is lower, axle sleeve quick abrasion during water pump operation.And the mechanical seal frictional resistance is little, and external sealed is good, and the life-span is long, but internal leakage is greatly its deficiency.Secondly, the impeller ring of known single-stage double-suction pump all is to adopt the sealing of semi-ring crack on the static seal face.Internal leakage is bigger like this.
Summary of the invention
Existing with the big problem of single-stage double-suction centrifugal pump internal leakage in order to overcome, the utility model provides a kind of minute-pressure labyrinth seal energy-saving pump.This minute-pressure labyrinth seal energy-saving pump not only can improve pump efficiency, and can make seal life longer.
The technological scheme that the utility model adopted is: this minute-pressure labyrinth seal energy-saving pump passes through the hyperbaric chamber and the Floating Ball Liquid Level feeder 1 of pump, feedwater piping 5, and shaft sealer is linked in sequence.Floating Ball Liquid Level automatic water replenishing device 1 reduces high pressure water, carry out shaft seal in mazy type machine envelope by the press water that reduces again, the internal leakage of shaft sealing is reduced, impeller ring 4 adopts the axial static seal of mazy type of loopful to reduce internal leakage on the static seal face simultaneously, thereby reaches the purpose that improves pump efficiency.
The beneficial effects of the utility model are: mazy type machine envelope longer service life when reducing the water pump internal leakage and raising the efficiency.And simple in structure, cost is low.
Description of drawings
Below in conjunction with drawings and Examples model utility is further specified.
Fig. 1 is minute-pressure labyrinth seal energy-saving pump embodiment vertical section structure figure.
Fig. 2 and Fig. 3 are the partial enlarged drawings of Fig. 1.
Among the figure, the 1st, Floating Ball Liquid Level feeder, the 2nd, the motivation envelope (moving axis cover), the 3rd of band square type groove, the quiet machine big envelope (forming mazy type machine envelope), the 4th of band square type groove, mazy type impeller ring, the 5th, seal arrangement supply pipe, the 6th, pump cover, 7 pump housings, the 8th, impeller, the 9th, impeller key, the 10th, sealing cover, 11 pump shafts, 12 bearing supports by 2 and 3 and 10.
Embodiment
In the drawings, Floating Ball Liquid Level feeder 1 be connected by bolt (pressure medium enters in the water supply tank by pipe, float valve), flexible pipe 5 one ends on the top of pump cover 6 connect Floating Ball Liquid Level feeder 1 in addition end be connected the import of the maze type seal arrangement of water pump.Water pump vane 8, impeller key 9, maze type seal arrangement (forming), bearing by the moving axis cover 2 that has square type groove with by dead axle cover 3 (can use filler) and the sealing cover 10 that have square type groove, etc. be engaged in proper order on spools 11 by nut check, rotating part is a rotor.The bearing of rotor cooperates with bearing support 12 again and with bolt bearing support 12 is fastened on the pump housing 7, at last pump cover 6 usefulness bolts and the dead axle cover 3, the pump housing 7 that have O type cushion rubber is linked into an integrated entity.
Claims (3)
1, a kind of minute-pressure labyrinth seal energy-saving pump on the double-suction centrifugal pump pump shaft sealing device, comprises pump chamber high-pressure feed water pipeline, and shaft sealer is characterized in that: the hyperbaric chamber of pump and Floating Ball Liquid Level feeder (1), and feedwater piping (5), shaft sealer is linked in sequence.
2, minute-pressure labyrinth seal energy-saving pump according to claim 1 is characterized in that: shaft sealer is to cooperate a kind of maze type machine envelope that forms by moving axis cover (2) with square type groove tooth with static seal gland (3).
3, minute-pressure labyrinth seal energy-saving pump according to claim 1 is characterized in that: water pump seat (7), and impeller ring (4), the stationary fit between the pump cover (6) is the mazy type axial seal of loopful.
