Description
Technical field:
The utility model is mainly used in the collection of the hydraulic generator unit guide bearing portion excessive mist of oil in cover turbine oil groove static and dynamic sealing place.
Background technique:
Current; The turbine oil that hydraulic generator unit guide bearing portion cover is used for lubricating is rotated parts at oil groove and carries out a large amount of mist of oil of expanded back formation; These mist of oils outwards overflow from packing seal lid and main shaft dynamic and static gaps, and the mist of oil that overflows has had a strong impact on the unit insulation and brought hidden danger to unit safety operation; Especially it is just even more serious to be in the phenomenon of outwards being overflowed by expanded mist of oil in the turbine oil groove below the rotor; Because below rotor and between the oil groove packing seal lid; The formed huge cooling air of fan produces the ring vaccum district; Outside sucking-off is covered through upper and lower packing seal in this ring vaccum district fixedly mist of oil in the oil groove, and it is excessive to have aggravated mist of oil.Simultaneously, the ring cavity of packing seal design is unreasonable, also is to cause one of excessive reason of mist of oil.The fluid oil that the mist of oil that overflows forms not only brings the big workload of tool to unit maintenance; And cause the pollution of basin, downstream water quality; For this reason; The hydraulic generator unit be badly in need of a kind of can overcome fan on the rotor forms the ring vaccum district to the mist of oil in the fixing oil groove inhale outward, annular chamber is reasonable and have the oil suction mist cover of filtration mist of oil, through such oil suction mist cover excessive mist of oil is purified by oil suction mist pipe suction purification plant once more.
Summary of the invention:
The purpose of the utility model just provides and a kind ofly can overcome the ring vaccum district to reasonable by the outer suction effect of expanded mist of oil, annular chamber in the fixing oil groove; The technological scheme that has the mist of oil filtering function again; It is characterized in that, be following packing seal lid center fixation with the main shaft in fixing oil groove upper end, covers the oil return screw of processing two M16～M25 in the face of the title place in packing seal down; In two oil return screws, load onto U type return tube respectively; In two oil return screw outsides,, the distinguish filter is housed in the bearing support inboard through the fixing a plurality of bearing supports of support bracket bolt; Be fixed on the distinguish filter on the corresponding bearing support through upper and lower two-layer distinguish pressure ring band and fixing bolt; Be fixed on last packing seal lid on the lower cover upper flange, and the packing seal interior surface is closely contacted with distinguish filter upper end, be fixed with distinguish flexible sealing body and the inboard distinguish air guide sleeve that multilayer distinguish baffle ring fixedly is housed to the upper end; Be fixed on the packing seal lid through air guide sleeve lower flange and following fixing bolt and lean on main shaft one side; Internal radius and main shaft external diameter distance that multilayer distinguish baffle ring is formed are 1.5～5mm all, and the ring internal diameter that the distinguish flexible sealing body is constituted slightly contacts with the main shaft external diameter, and symmetry is equipped with two oil suction mist Guan Bingyu internal communication in following packing seal lid side.Packing seal lid, oil suction mist pipe were covered, go up in packing seal under the anti-vacuum oil suction mist cover of filtering type comprised.
The technique effect that technological scheme realized that the utility model provided is such: when the hydraulic generator unit was worked, rotor drove fan-shaped and has become huge cooling air, and this cooling air has formed the ring vaccum district at the wind inlet of fan place.The rotary component of guide bearing constantly makes turbine oil expanded in fixing oil groove inside; Make turbine oil form the mist of oil fluffing zone; The dynamic clearance amount of packing seal lid and main shaft formation was excessive to the excessive district of mist of oil under the mist of oil of fluffing zone passed through, and the mist of oil that arrives the excessive district of mist of oil that overflows is overlapped by crucial portions such as sucking-off pollution unit stator and rotor under the effect in ring vaccum district; In the present technique scheme,, improved time packing seal lid and last packing seal cover attaching construction, reasonably strengthened the annular chamber between time packing seal lid and the last packing seal lid for solving the problem of contaminated with oil mist.In annular chamber, be fixed on the distinguish filter on a plurality of L type bearing supports through upper and lower two-layer distinguish pressure ring band and fixing bolt correspondence; A plurality of L type bearing supports are fixed on down packing seal through support bracket bolt again and cover face; The mist of oil in excessive district before through oil suction mist pipe sucking-off to purification plant; To purify mist of oil through the distinguish filter, to alleviate the burden of purification plant.The mist of oil that the distinguish filter purifies forms fluid oil, and these fluid oils are installed in the U type return tube in inboard two the symmetrical M16～M25 oil return screws of distinguish filter through symmetry again, is expelled back into fixedly in the oil groove.U type return tube has certain sealing, and its height is confirmed according to the negative pressure of oil suction mist pipe.Distinguish filter upper/lower terminal should closely contact with upper and lower packing seal cap surface.In order to solve the ring vaccum district to the outer technical problem of inhaling of the mist of oil in the excessive district of mist of oil; Lean on main shaft one side that the distinguish air guide sleeve is housed at last packing seal lid; Distinguish air guide sleeve upper end has uses the fixing distinguish flexible sealing body of fixing bolt on annular distinguish pressure ring and the air guide sleeve; Distinguish flexible sealing body internal diameter slightly contacts with the main shaft external diameter; Be fixed with multilayer distinguish baffle ring in distinguish air guide sleeve inboard, so the distinguish air guide sleeve has overcome the problem of ring vaccum district to the outside sucking-off of mist of oil in the excessive district of mist of oil fully.
The related technological scheme of the utility model is simple and reasonable, has not only thoroughly solved the excessive technical barrier of hydraulic generator unit mist of oil, has also alleviated the purification burden of purification plant.Have novelty, creativeness and practicability in the art, for the generator set in related domain is avoided contaminated with oil mist, energy saving guarantees that dirty water quality provides a good technological scheme, will be widely used on the hydraulic generator unit.
