Abstract
The utility model discloses a horizontal hydraulic turbine set. The horizontal hydraulic turbine set comprises a spindle (1), a runner (2) and a spindle seal (3) are arranged on the spindle (1), and a front cover plate (4) is arranged on the runner (2). The horizontal hydraulic turbine set is characterized in that a vane pump connected with a runner crown (5) is arranged at the position of the runner crown (5) and the vane pump corresponds to the front cover plate (4). The horizontal hydraulic turbine set has the advantages of being simple in structure and convenient to install; by the adoption of the horizontal hydraulic turbine set, water entering the spindle seal can be greatly reduced, the damage cycle and the replacing cycle of the spindle seal are prolonged, and therefore efficient and stable running of the horizontal hydraulic turbine set is guaranteed.
Description
Technical field
The utility model relates to a kind of water wheels unit, particularly a kind of horizontal hydraulic unit.
Background technique
At present, in the horizontal unit of routine, the sealing between runner and front shroud adopts the mode of clearance type, step type and comb-shaped to carry out conventionally, and its main sealing principle is the acting in conjunction of linear loss and volumetric loss, reduce pressure flow velocity and the pressure of water, play the effect of sealing.But the press water by runner seals, after the draining of front shroud waste pipe, still has a large amount of press waters to enter main shaft seal and flow velocity is very fast; cause the fragile leakage of main shaft seal; the leakage once be damaged, just must shut down maintenance, so just causes power station resource and economic loss.
Model utility content
The purpose of this utility model is just to provide a kind of horizontal hydraulic unit that can effectively prevent that main shaft seal from damaging.
The purpose of this utility model is to realize by such technological scheme, a kind of horizontal hydraulic unit, comprise main shaft, on main shaft, be provided with runner and main shaft seal, on described runner, be provided with front shroud, at described runner crown, place is provided with the vane pump being connected with runner crown, and described vane pump is corresponding with described front shroud.
Wherein, described vane pump comprises the ring flat-plate with weep hole, center, upper-end surface at described ring flat-plate is vertically provided with the cylinder with water inlet, and described water inlet is corresponding with described weep hole, is provided with the blade that bottom is connected with ring flat-plate upper-end surface on the outer wall of described cylinder.
Further, described blade is 8-16 sheet, and is distributed on the outer wall of cylinder.
Owing to having adopted technique scheme, the utlity model has advantage simple in structure, easy for installation, adopt it can make the water that enters main shaft seal greatly reduce, extended damage and the replacement cycle of main shaft seal, guaranteed unit efficiently, stably operation.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 the utility model Leaf pump is along axial direction schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement on the present embodiment essence spirit or substitute, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of horizontal hydraulic unit, comprise main shaft 1, on main shaft 1, be provided with runner 2 and main shaft seal 3, on described runner 2, be provided with front shroud 4, at described runner crown, 5 places are provided with the vane pump being connected with runner crown 5, and described vane pump is corresponding with described front shroud 4.
Wherein, as shown in Figure 2, described vane pump comprises the ring flat-plate 7 with weep hole 6, at the center, upper-end surface of described ring flat-plate 7, be vertically provided with the cylinder 9 with water inlet 8, described water inlet 9 is corresponding with described weep hole 6, is provided with the blade 10 that bottom is connected with ring flat-plate 7 upper-end surfaces on the outer wall of described cylinder 9.
Further, described blade 10 is 8-16 sheet, and is distributed on the outer wall of cylinder 9.
In the utility model, by the press water of runner seals, do not enter runner crown 5 after 11 drainings of protecgulum waste pipe before, under rotary centrifugal force effect, enter vane pump and pressurize after by protecgulum waste pipe 11, drain into downstream, thereby the seepage hydraulic pressure and the flow velocity that enter main shaft seal 3 are lower, guarantee that the water that enters main shaft seal 3 greatly reduces.
Claims (3)
1. a horizontal hydraulic unit, comprise main shaft (1), on main shaft (1), be provided with runner (2) and main shaft seal (3), on described runner (2), be provided with front shroud (4), it is characterized in that: at described runner crown (5), locate to be provided with the vane pump being connected with runner crown (5), described vane pump is corresponding with described front shroud (4).
2. horizontal hydraulic unit as claimed in claim 1, it is characterized in that: described vane pump comprises with the ring flat-plate of weep hole (6) (7), at the center, upper-end surface of described ring flat-plate (7), be vertically provided with the cylinder (9) of band water inlet (8), described water inlet (9) is corresponding with described weep hole (6), is provided with the blade (10) that bottom is connected with ring flat-plate (7) upper-end surface on the outer wall of described cylinder (9).
