Abstract
The utility model relates to a water turbine spindle sealing device. The sealing device comprises a rotating wheel upper canopy, a top cover, a labyrinth clearance seal, a water guide ring and a thrower, wherein the rotating wheel upper canopy is arranged at the periphery of the water turbine spindle and is fixed on the spindle; the top cover is arranged outside the spindle; the labyrinth clearance seal is arranged in a cavity formed by the rotating wheel upper canopy and the top cover; the water guide ring is fixed on the top cover; the thrower is fixed on the spindle and is arranged on the inner side of the water guide ring; and the water guide ring is connected to form a drainage pipe. The phenomena that the sealing piece is burnt and the spindle is worn and the like are avoided, and the water turbine spindle sealing device has the advantages of simple structure, convenience in detachment and maintenance, high sealing performance, long service life and the like.
Description
Technical field
The utility model relates to a kind of hydraulic turbine main shaft device, especially relates to a kind of hydraulic turbine main shaft sealing device.
Background technique
The effect of the hydraulic turbine main shaft sealing in the generating machinery is that the gap of blockading between rotating part and the standing part leaks.The quality of main shaft seal performance directly influences the safe and stable operation of unit.
Hydraulic turbine main shaft sealing generally adopts end face contact seal; Like packing_seal, material filling type sealing, individual layer or double-layer rubber sealing, radially or end face extractive carbon loaf (nylon block) sealing, water pump packing etc.; Adopt above-mentioned sealing means to be prone to the accident that causes main shaft seals such as Sealing and main shaft wearing and tearing, Sealing burn out, Sealing wears out to lose efficacy, influence unit safety operation.
The model utility content
For overcoming the deficiency of existing technology, the utility model provides the hydraulic turbine main shaft sealing device of a kind of simple in structure, good seal performance, long service life.
A kind of hydraulic turbine main shaft sealing device; Said seal arrangement comprises runner crown, top cover, labyrinth clearance sealing, water guiding ring and slinger ring, and runner crown is located at the hydraulic turbine main shaft periphery and is fixed on the main shaft, and top cover is located at the main shaft outside; Labyrinth clearance sealing is arranged in the cavity that runner crown and top cover surround; Water guiding ring is fixed on the top cover, and slinger ring is fixed on the main shaft and is located at the water guiding ring inboard, and said water guiding ring connects a waste pipe.
Adopt the labyrinth clearance sealing to improve the effect of sealing, through slinger ring and water guiding ring the water that spills is directly discharged from waste pipe, having prevented to leak axially spills along main shaft.
The utility model is difficult for causing the generation of phenomenons such as Sealing burns out, main shaft wearing and tearing, has simple in structure, advantages such as dismounting is easy to maintenance, good seal performance, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but the protection domain of the utility model is not limited to this.
With reference to Fig. 1, a kind of hydraulic turbine main shaft sealing device, said seal arrangement comprise runner crown 1, top cover 2, labyrinth clearance sealing 7, water guiding ring 4 and slinger ring 3; Runner crown 1 is located at hydraulic turbine main shaft 5 peripheries and is fixed on the main shaft 5; Top cover 2 is located at main shaft 5 outsides, and labyrinth clearance sealing 7 is arranged in the cavity that runner crown 1 and top cover 2 surround, and water guiding ring 4 is fixed on the top cover 2; Slinger ring 3 is fixed on the main shaft and is located at water guiding ring 4 inboards, and said water guiding ring 4 connects a waste pipe 6.
Water is through labyrinth clearance sealing 7; Labyrinth clearance sealing 7 produces resistance and its flow is reduced it; The water that spills in the labyrinth clearance sealing 7 throws away the back along water guiding ring 4 water guides through slinger ring 3 again, finally discharges from waste pipe 6, prevents the purpose of leaking and axially spilling along main shaft 5 thereby reach.
The utility model is located at the hydraulic turbine main shaft periphery with runner crown and is fixed on the main shaft, has avoided main shaft to contact with the direct of Sealing, has reduced the wearing and tearing of main shaft.
