Abstract
The utility model discloses a main shaft working sealing device of a horizontal water turbine. The main shaft working sealing device comprises a centrifugal sealing part, a clearance type sealing part, a filler sealing part, a water sealing box and water drainage pipes, wherein the centrifugal sealing part, the clearance type sealing part, the filler sealing part and the water sealing box are connected with a main shaft of the horizontal water turbine through a sealing seat and are sequentially arranged; and the water drainage pipes are arranged on the centrifugal sealing part, the clearance type sealing part, the filler sealing part and the water sealing box respectively. Leaked water passes through a runner wearing ring clearance seal, then is depressurized, and enters a pump plate centrifugal seal; the pump plate centrifugal seal is provided with the water drainage pipe which is used for removing most of silt and draining part of water; the remaining leaked water enters the clearance type sealing part, is depressurized and is prevented from being leaked; the leaked water passes through a second water drainage and silt removal pipe, and is further prevented from being leaked; and finally part of the leaked water is sealed by a filler seal and is drained by the water drainage pipes. The leakage of the silt and the water in the water turbine chamber is effectively controlled, and the main shaft working sealing device has a good sealing effect and applicable to a high-water-head and multi-silt power station.
Description
Technical field
The utility model relates to a kind of seal arrangement of water turbine, specifically relates to a kind of main shaft work-ing seal device of horizontal water turbine.
Background technique
The leak stoppage device that existing rotary wheel of water turbine uses mainly relies on seal ring, in service can the generation of seal ring leaked on a small quantity, the meeting of leaking enter machine and cheat along the gap between main shaft and fixed component, water turbine can't normally be moved, and the means of head it off routine are that seal arrangement is set on hydraulic turbine main shaft.The sealing device all is positioned between hydraulic turbine main shaft bearing and rotary wheel of water turbine, and sealing effect directly has influence on the normal operation of hydraulic generator unit.Because each parts of seal arrangement are vulnerable part, need often to change.Especially high concentration of sediment power station, under the wearing and tearing of silt, each parts of seal arrangement are more easy to wear; replacement frequency is higher, makes the power station be overhauled by forced-stopping machine, and the main shaft work-ing seal of some unit does not have the sand discharge structure; seal arrangement needs often to change, and has reduced the power benefit in power station.
The model utility content
The purpose of this utility model will be eliminated above-mentioned the deficiencies in the prior art and shortcoming exactly, a kind of main shaft work-ing seal device of horizontal water turbine is provided, effectively draining, sand discharge reduce the frequency of changing main shaft work-ing seal spare, make the user obtain the maximum generation benefit.
For reaching above-mentioned technique effect, the utility model adopts following technological scheme: a kind of main shaft work-ing seal device of horizontal water turbine comprises pump plate centrifugal seal parts, slit seal parts, filler sealing parts, water sealing box and waste pipe, described pump plate centrifugal seal parts, slit seal parts, filler sealing parts connect the main shaft of horizontal water turbine and set gradually by sealing seat with water sealing box, are equipped with waste pipe on described centrifugal seal parts, slit seal parts, filler sealing parts and water sealing box.
Preferably, also comprise baffle ring between described water sealing box and main shaft.
Preferably, described pump plate centrifugal seal parts are comprised of pump plate welding runner.
Preferably, described slit seal is comprised of sealing seat and runner.
Preferably, described gland sealed filler puts together on sealing seat by bolt with pressure ring, and filler is close to main shaft, forms packing seal.
Preferably, described water sealing box puts together on sealing seat, with the middle one deck oil-resistant rubber slab that filled of sealing seat.
Preferably, described sealing seat puts together on base ring, has filled one deck oil-resistant rubber slab in the middle of sealing seat and base ring.
The beneficial effects of the utility model:
The main shaft work-ing seal device of the disclosed a kind of horizontal water turbine of the utility model, simple in structure, easily manufactured, percolating water is after sealing through the runner leak stoppage czermak space, decompression enters pump plate centrifugal seal, and pump plate centrifugal seal arranges several drainings, and here most of silt and a part of water are excluded through these waste pipes by the effect of pump plate, residue is leaked and is further reduced pressure when entering the slit seal parts, overcomes leakage.A small amount of percolating water and silt are drained through the waste pipe of this place's device, and the residue of minute quantity is leaked and entered packing seal.
