Description
[technical field]
The utility model relates to a kind of hydro-electric power generating equipment field, particularly a kind of water turbine.
[background technique]
Hydraulic power potentials is a renewable energy sources, is constituent element important in China's energy resource structure.China is the country of a fully-loaded stream, particularly in China the Yellow River and southwestern the Northwest, builds water conservation reservoir on heavily silt-carrying river, builds hydroelectric power plant, and sand erosion is inevitable.
Sand erosion is a worldwide problem, is not that manufactory just can solve.It shows that mainly the repair cycle shortens the maintenance workload increase.All the time, the structure of the water turbine that horizontal clockwise direction rotates, it all is protecgulum, runner, main shaft seal, main shafts etc. split out and pack into from generator end, bonnet, tail water is taken over, the tail water bend pipe splits out and packs into from the tail water end, that is to say that easy-abrasion part splits out from the protecgulum direction, and cause bearing, flywheel, generators etc. almost are that complete machine is torn open imperial and installation, this structure to water-quality ratio preferably the power station be no problem, all be then to carry out complete machine mounting or dismounting maintenance the overhaul life, but for the high concentration of sediment power station, frequent maintenance certainly will cause a large amount of energy losses, therefore must be improved to shorten engineering time its structure.
[model utility content]
The technical problems to be solved in the utility model is to provide the water turbine of tearing the formula structure behind a kind of protecgulum open, and the easy-abrasion part of water turbine can be under the situation of motionless main shaft, all splits out and packs into from the tail water direction, has made things convenient for maintenance, has shortened dead time.
The technical problems to be solved in the utility model is achieved in that the water turbine of tearing the formula structure behind a kind of protecgulum open, comprise the tail water bend pipe, tail water is taken over, draft cone, bonnet, stator, gate operating mechanism, seat ring, protecgulum, runner, main shaft seal spare, main shaft and spiral case, described tail water bend pipe, tail water is taken over, draft cone connects successively, described draft cone and runner are fixed on the described main shaft, described stator and gate operating mechanism are fixed on the bonnet, wherein: described spiral case and seat ring are connected to one, described protecgulum and bonnet the be placed in front side and the rear side of spiral case, described stator is located between described protecgulum and the bonnet, described seat ring comprises one radial ringed and an axial ring surface, described protecgulum is set in outside the described main shaft and is connected to radial ringed inboard of described main shaft seal spare and described seat ring, described bonnet is connected in the axial ring surface of described seat ring, and the outside of this axial ring surface is connected in spiral case, inboard supporting is located at described protecgulum and bonnet, the front end of described runner pushes against in described protecgulum, and the rear end pushes against in described draft cone.
Advantage of the present utility model is: tear the formula structure open after the water turbine protecgulum is arranged to, its with seat ring also can mode for convenience detach being connected, during mounting or dismounting; protecgulum and seat ring mutual noninterference, easy to maintenance, shortened dead time effectively; make full use of the water energy, economic benefit is improved.Avoided former easy-abrasion part to split out, and caused that bearing, flywheel, generator etc. almost are that complete machine is torn open imperial and installation from the protecgulum direction.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
[embodiment]
See also shown in Figure 1, tear the water turbine of formula structure behind a kind of protecgulum open, comprise tail water bend pipe 1, tail water takes over 2, draft cone 3, bonnet 4, stator 51 and gate operating mechanism 52, seat ring 6, protecgulum 7, runner 8, main shaft seal spare 9, main shaft 10 and spiral case 11, described tail water bend pipe 1, tail water takes over 2, draft cone 3, connect successively, described draft cone 3 and runner 8 are fixed on the described main shaft 10, described stator 51 and gate operating mechanism 52 are fixed on the bonnet, described spiral case 11 and seat ring 6 are connected to one, described protecgulum 7 and bonnet 4 the be placed in front side and the rear side of spiral case 11, described stator 51 is located between described protecgulum 7 and the bonnet 4, described seat ring 6 comprises one radial ringed 61 and an axial ring surface 62, from axial section, this radial ringed 61 and axially ring surface 62 be connected to form " L " shape structure of a symmetry.Described protecgulum 7 is set in outside the described main shaft 10 and is connected to radial ringed 61 inboard of described main shaft seal spare 9 and described seat ring 6, described bonnet 4 is connected in the axial ring surface 62 of described seat ring 6, and the outside of this axial ring surface 62 is connected in spiral case 11, inboard supporting is located at described protecgulum 7 and bonnet 4, the front end of described runner 8 pushes against in described protecgulum 7, and the rear end pushes against in described draft cone 3.
Because the seat ring in the utility model is designed to " L " shape structure and is connected to one with spiral case 11, during assembling, can earlier protecgulum 7 be packed into from the tail water end, be set in outside the main shaft 10, be locked at radial ringed 61 inboard on the seat ring with stud 72, reinstall runner 8, draft cone 3, and with runner 8 and draft cone 6 usefulness keys and bolton on main shaft 10, and the front end that makes runner 8 pushes against in protecgulum 7, and the rear end pushes against in draft cone 3.Load onto stator 51 then, reinstall bonnet 4, after making stator 51 and bonnet 4 being connected, be locked on the axial ring surface 62 on the seat ring, load onto gate operating mechanism 52, load onto tail water then and take over 2, tail water bend pipe 1 with stud 42; Load onto main shaft seal spare 9 at last.During dismounting, directly carry out conversely by the order of packing into, get final product until pulling down the parts that need from the tail water end.
In sum, the utility model is torn the formula structure open after the water turbine protecgulum is arranged to, its with seat ring also can mode for convenience detach being connected; during mounting or dismounting, protecgulum and seat ring mutual noninterference, easy to maintenance; shortened dead time effectively, made full use of the water energy, economic benefit is improved.Avoided former easy-abrasion part to split out, and caused that bearing, flywheel, generator etc. almost are that complete machine is torn open imperial and installation from the protecgulum direction.
