Abstract
The utility model relates to a kind of axial-flow pump energy-saving water tank; annular slab, a sealing change and a lubrication water pipe composition is connected primarily of a pump shaft, a diffuser, a water guide cone, a water pilot bearing; lubrication water pipe is casted in diffuser; protective action is served to lubrication water pipe; further raising working life; meanwhile, rapidoprint is also saved.
Description
Technical field
The utility model relates to vertical-type axial-flow pump field, specifically, is a kind of axial-flow pump energy-saving water tank.
Background technique
Large-sized vertical-type axial-flow pump will bear larger axial force, very large to the wearing and tearing of easily damaged parts, therefore except carrying out the lubrication to the thrust-bearing and selfaligning bearing that bear axial force in transmission device, also tackle two water pilot bearings in the pump housing and carry out continuous water lubrication, general upper water pilot bearing will carry out flushing lubrication by external cooling water before water pump start.Lower water pilot bearing floods in media as well, need not establish sparge water specially.But at special occasions, such as, time occasion (pumping Huanghe water) that impurity content is larger, lower water pilot bearing lubricates with regard to needing external tap water.Now should be taken into account water lubrication sealing problem.Usually above diffuser, separately establish water tank, keep apart with medium.Water tank, primarily of casing, rubber plate, water tank pressure ring and sealing change composition, installs lubrication water pipe at cabinet exterior, carries out flushing lubrication by the extraneous tap water of pipe joint.This structure raising middle flask bulk area is large, and while waste material, lubrication water pipe soaks in media as well for a long time, comparatively large to the wearing and tearing of lubrication water pipe, has a strong impact on its life-span.
Model utility content
The utility model object proposes a kind of novel axial-flow pump energy-saving water tank, overcomes the problems of the prior art.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of axial-flow pump energy-saving water tank, it is characterized in that, comprises,
One pump shaft;
One diffuser, described diffuser is surrounded on outside described pump shaft, and described diffuser is primarily of an inner ring body, an outer ring body and to be connected between described inner ring body with described outer ring body multiple is connected blade, described outer ring body has a water inlet interface;
One water guide cone, it is outer and be arranged at one end of the inner ring body of described diffuser that described water guide cone is surrounded on described pump shaft;
One water pilot bearing, described water pilot bearing is surrounded between the inner ring body of described diffuser and described pump shaft;
One connects annular slab, described connection annular slab is surrounded on outside described pump shaft, described connection annular slab has a Inner periphery and outer periphery, described outer periphery are connected between the inner ring body of described water guide cone and described diffuser, described inner circumference edge and described pump shaft form a gap, wherein, the inner ring body of described connection annular slab and described water pilot bearing, described diffuser and described pump shaft surround an accommodating water cavity;
One sealing change, described sealing change is surrounded on described pump shaft and adjacent to described connection annular slab, described sealing change is provided with a water tank pressure ring and a rubber plate with described connection between annular slab, seals described gap by this; And,
One lubrication water pipe, described lubrication water pipe has a first end and one second end, the first end of described lubrication water pipe is combined with the inner ring body of described diffuser and is connected with described accommodating water cavity, and the second end of described lubrication water pipe is combined with the outer ring body of described diffuser and is connected with described water inlet interface.
Compared with prior art, the utility model has the advantage of, protective action is served to lubrication water pipe, improves working life further, meanwhile, also save rapidoprint.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 2, shown in figure is form primarily of pump shaft 1, diffuser 2, water guide cone 3, water pilot bearing 4, connection annular slab 5, sealing change 6 and a lubrication water pipe 7.
Described diffuser is surrounded on outside described pump shaft, and described diffuser is primarily of an inner ring body, an outer ring body and to be connected between described inner ring body with described outer ring body multiple is connected blade, described outer ring body has a water inlet interface.It is outer and be arranged at one end of the inner ring body of described diffuser that described water guide cone is surrounded on described pump shaft.Described water pilot bearing is surrounded between the inner ring body of described diffuser and described pump shaft.Described connection annular slab is surrounded on outside described pump shaft, described connection annular slab has a Inner periphery and outer periphery, described outer periphery are connected between the inner ring body of described water guide cone and described diffuser, described inner circumference edge and described pump shaft form a gap, wherein, the inner ring body of described connection annular slab and described water pilot bearing, described diffuser and described pump shaft surround an accommodating water cavity.Described sealing change is surrounded on described pump shaft and adjacent to described connection annular slab, described sealing change is provided with water tank pressure ring 8 and a rubber plate 9 with described connection between annular slab, seals described gap by this.Described lubrication water pipe has a first end and one second end, the first end of described lubrication water pipe is combined with the inner ring body of described diffuser and is connected with described accommodating water cavity, and the second end of described lubrication water pipe is combined with the outer ring body of described diffuser and is connected with described water inlet interface.Further, described rubber plate is arranged at described connection on annular slab all in a fixed way with described water tank pressure ring.
Be not difficult to find out, compared with prior art, eliminate casing, by diffuser as casing, top adds connecting plate sealing.Lubrication water pipe is now casted in diffuser blade, also serves protective action, improve working life further to lubrication water pipe.From before want independent die sinking casting box to only with one block plate process connecting plate, new structure, compared with original structure, saves material and the processing charges of nearly half, has also responded the policy of energy-conserving and environment-protective.
Below only have expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
