Abstract
A kind of water pump, hydraulic turbine main shaft sealing device, relate to field of mechanical technique, particularly the sealing mechanism of a kind of water pump, water turbine.Comprise the main shaft of water turbine, sealing seat; Sealing seat is nested with on main shaft, is provided with gap and forms packing cavity, arrange filler in packing cavity between sealing seat and main shaft; In packing cavity, arrange spacer, spacer is nested with on main shaft, and spacer both sides are respectively equipped with filler, in packing cavity, arrange filler pressing; Sealing seat arranges a water channel, and the outer end of water channel connects water diversion joint, and the main shaft near sealing seat arranges impeller, impeller is along with main axis, arrange water-resisting mask at impeller outer, one end of water-resisting mask is fixedly connected on the inner of sealing seat, the other end opening of water-resisting mask.This device acts on water pump or water turbine, when flowing water impurity more particularly sand content is larger, current can be pushed open by impeller, protect greatly sealing and miscellaneous part, the working life of water turbine or water pump is extended greatly.
Description
Technical field
The utility model relates to field of mechanical technique, particularly the sealing mechanism of a kind of water pump, water turbine.
Background technique
Water pump domestic at present, the main shaft seal of water turbine generally adopt conditioning sealing and the sealing of piston type rubber seal end contact, and these two kinds of seal form have used for many years, and structure is simple, easy installation and removal; But also there are some shortcomings: when cross flowing water impurity more particularly sand content is larger, due to the friction of silt, as sealing rubber parts or filler rapid wear more serious, simultaneously can the surface of contact that contacts with it of rapid wear, sealing will be changed have more than is needed half a year and also there will be pit in macro-axis cylndrical surface simultaneously, cause sealing effect to lose efficacy, finally make that whole turbine-generator units is out of service changes easily damaged parts, make troubles to production.
Model utility content
In order to overcome above-mentioned defect, the utility model provides a kind of water pump, hydraulic turbine main shaft sealing device.
The utility model comprises main shaft, the sealing seat of water turbine; Described sealing seat is nested with on described main shaft, and the inner and the described main shaft of described sealing seat closely cooperate, and are provided with gap and form packing cavity, arrange filler in described packing cavity between described sealing seat and described main shaft; In described packing cavity, arrange spacer, described spacer is nested with on described main shaft, and described spacer both sides are respectively equipped with filler, in described packing cavity, arrange filler pressing; Described sealing seat arranges a water channel, described spacer is provided with some through holes, the inner of described water channel is corresponding with the through hole of described spacer, the outer end of described water channel connects water diversion joint, main shaft near described sealing seat arranges impeller, and described impeller, along with described main axis, arranges water-resisting mask at described impeller outer, one end of described water-resisting mask is fixedly connected on the inner of described sealing seat, the other end opening of described water-resisting mask.
The utility model arranges impeller by the inner at water seal arrangement, and impeller rotates together with main shaft, and water is pushed open by impeller, avoids it to enter sealing, and water-resisting mask is used to provide enough pressure, ensures the effect of impeller draining; This device acts on water pump or water turbine, when flowing water impurity more particularly sand content is larger, current can be pushed open by impeller, protect greatly sealing and miscellaneous part, the working life of water turbine or water pump is extended greatly.
Water-resisting mask described in the utility model is one end pipe, and one end seal welding of described pipe is at the tail end of described sealing seat, and the inwall of described pipe is near described impeller; Pipe can ensure to ensure that drainage effect by the pressure that the current of impeller periphery are formed.
Impeller described in the utility model is point half assembly parts, and it comprises half-axile sleeve, and each half-axile sleeve arranges some blades respectively, and described blade bends along water (flow) direction, and each half-axile sleeve fixes formation whole parts by bolt, nut; Impeller split arranges by this set, facilitates the replacing of impeller, namely facilitates replacing, maintenance.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of structural representation of impeller.
Embodiment
As shown in Figure 1, this water pump, hydraulic turbine main shaft sealing device, comprise the main shaft 1 of water turbine, sealing seat 2; Sealing seat 2 is nested with on main shaft 1, and the inner and the main shaft 1 of sealing seat 2 closely cooperate, and are provided with gap and form packing cavity 3, arrange filler 4 in packing cavity 3 between sealing seat 2 and main shaft 1; In packing cavity 3, arrange spacer 5, spacer 5 is nested with on main shaft 1, and spacer 5 both sides are respectively equipped with filler 4, arrange filler pressing 6 in packing cavity 3; Sealing seat 2 arranges a water channel 7, the inner of water channel 7 is corresponding with the through hole of spacer 5, the outer end of water channel 7 connects water diversion joint 8, main shaft 1 near sealing seat 2 arranges impeller 9, impeller 9 rotates along with described main shaft 1, install water-resisting mask 10 at impeller 9 peripheral hardware, one end of water-resisting mask 10 is fixedly connected on the inner of sealing seat 2, the other end opening of water-resisting mask 10.
Preferably, water-resisting mask 10 is one end pipe, and one end sealing of pipe is fixed on the inner of described sealing seat 2, and the inwall of pipe is near described impeller 9.
Preferably, impeller 9 comprises two and half round sleeves 11, and half and half round sleeve 11 arranges some blades 12 respectively, and blade 12 bends along water (flow) direction, and two and half round sleeves 11 are by bolt, the fixing formation complete axle sleeve of nut 13,14.
