Description
Technical field
The utility model relates to the distribution piping in the radial-thrust bearing in a kind of hydraulic turbine generator.
Background technique
Horizontal hydrogenerator often will be used radial-thrust bearing.A kind of radial-thrust bearing usually is used for different units, the water turbine difference of being joined sometimes, the hydraulic turbine generator difference of being joined sometimes, that is to say the suffered radial load of radial-thrust bearing and thrust loading since institute to join type different and constantly change, simultaneously the rotating speed of unit is because the type difference is joined by institute is also changing, so just cause thrust bearing shoe valve temperature height (when thrust loading is bigger) sometimes inevitably, sometimes watt temperature height (when radial load is bigger) radially.If a watt temperature exceeds permitted value, then can cause the tile kilning accident, influence the normal operation of unit.
Summary of the invention
The purpose of this utility model is in order to address the above problem, design the reasonable balance of a kind of energy radially watt and thrust bearing shoe valve watt temperature, they all can be worked under normal watt of temperature, and the radial-thrust bearing structure is not made oil content pipe arrangement in the hydraulic turbine generator radial-thrust bearing of big change again.
The technical solution of the utility model is achieved in that the oil content pipe arrangement in a kind of hydraulic turbine generator radial-thrust bearing, it comprises main shaft, bearing spider, radially watt, watt oil inlet pipe radially, thrust bearing shoe valve, the oil-feed cover, thrust disc and wing pump, wherein main shaft is seated in radially watt, thrust bearing shoe valve with radially watt all be contained on the bearing spider, the oil-feed cover links to each other with bearing spider by bolt, thrust disc links to each other with main shaft, wing pump is housed on thrust disc, radially be provided with the oil content pipe arrangement between watt oil pipe and the oil-feed cover, oil content pipe arrangement one end links to each other with a watt oil inlet pipe radially, the other end links to each other with the oil-feed cover, radially watt oil inlet pipe the other end with radially watt link to each other.It is assembled the oil content pipe arrangement by set screw nut, steel pipe, Cock screw and swab case, and swab case is a funnel shaped.
The beneficial effects of the utility model are: under the constant situation of cold oil total amount, by regulating the sectional area size of steel pipe filler opening, reasonable distribution is to radially watt and the oil mass size of thrust bearing shoe valve, thereby regulate effectively and balance radially watt with the Wa Wen of thrust bearing shoe valve, they all can be worked under normal watt of temperature.The utility model is simple in structure, and reforming cost is low, and is easy to implement, and convenient for installation and maintenance, can be widely used in various radial-thrust bearings.
Description of drawings
Fig. 1 is an assembly structure schematic representation of the present utility model;
Fig. 2 is the structural representation of oil content pipe arrangement;
Fig. 3 is the structural representation of oil box.
Each unit number is among the figure: the 1-main shaft; The 2-bearing spider; 3-radially watt; 4-is watt oil inlet pipe radially; 5-oil content pipe arrangement; The 6-thrust bearing shoe valve; 7-oil-feed cover; The 8-thrust disc; The 9-wing pump; The 10-set screw nut; The 11-steel pipe; The 12--Cock screw; The 13-oil box.
Embodiment
As Fig. 1,2, shown in 3, oil content pipe arrangement in a kind of hydraulic turbine generator radial-thrust bearing, it comprises main shaft 1, bearing spider 2, radially watts 3, watt oil inlet pipe 4 radially, thrust bearing shoe valve 6, oil-feed cover 7, thrust disc 8 and wing pump 9, wherein main shaft 1 is seated in radially on watts 3, thrust bearing shoe valve 6 with radially watts 3 all be contained on the bearing spider 2, oil-feed cover 7 links to each other with bearing spider 2 by bolt, thrust disc 8 links to each other with main shaft 1, wing pump 9 is housed on thrust disc 8, radially be provided with oil content pipe arrangement 5 between watt oil inlet pipe 4 and the oil-feed cover 7, oil content pipe arrangement 5 one ends link to each other with watt oil inlet pipe 4 radially, and the other end links to each other with oil-feed cover 7, radially watt oil inlet pipe 4 the other ends with radially watts 3 link to each other.It is assembled oil content pipe arrangement 5 by set screw nut 10, steel pipe 11, Cock screw 12 and swab case 13, and swab case 13 is a funnel shaped.
The utility model oil content pipe arrangement 5 mounts are on oil-feed cover 7, oil box 13 on the oil content pipe arrangement 5 is made a funnel shaped, device is in the position near wing pump 9, the high pressure cold oil that comes on the wing pump 9 directly enters in the funnel of oil box 13, and then along steel pipe 11, radially watt oil inlet pipe 4 enters radially watt 3 a places cooling, control by the sectional area of control steel pipe 11 filler openings and to enter radially watts 3 oil inlet quantity, so control radially watts 3 Wa Wen be in normal state.As controlling the sectional area of steel pipe 11 filler openings, only need at sector of filler opening weldering, the area size of sector is adjusted as required.Being mixed into thrust bearing shoe valve 6 by a part of high pressure cold oil that comes on cold oil that comes on thrust disc 8 pumps and the wing pump 9 cools off.
Because the effect of oil content pipe arrangement 5, under the constant situation of cold oil total amount, by regulating the sectional area size of steel pipe 11 filler openings, reasonable distribution is to radially watts 3 and the oil mass size of thrust bearing shoe valve 6, thereby regulate effectively and balance radially watts 3 and the Wa Wen of thrust bearing shoe valve 6, they all can be worked under normal watt of temperature.
