Abstract
The utility model relates to the field of water pump equipment, in particular to a double suction pump impeller fixing structure which is characterized in that the fixing structure is arranged on the other side of an impeller and comprises a front nut, a back nut and a clamping ring which is placed between the front nut and the back nut, the front nut, the back nut and the clamping ring are arranged on a driving shaft in a sleeved mode, wherein the front nut and the back nut are matched with the driving shaft in a thread mode, and the clamping ring is respectively matched with the driving shaft, the front nut and the back nut in a clamping-limiting mode. The double suction pump impeller fixing structure has the advantages of being simple in structure, low in production cost and capable of being widely used for impeller locking of a large-scale pump, and the double suction pump impeller fixing structure is especially suitable for locking a water pump impeller which is started frequently.
Description
Technical field
The utility model relates to the pump equipment field, is specifically related to a kind of double-suction pump impeller fixed structure.
Background technique
The water pump of existing market, in actual moving process, often can run into following two kinds of situations: the first, when the examination electricity, often because the motor wiring is incorrect, cause the unit counter-rotating, cause rotor part collective loosening, impeller can produce axial float, when serious, can cause unit to damage; The second, in water pump when shutdown,, due to supply disconnecton, fed sheet of a media moment is blocked by outlet valve, to the impeller of water pump, usually can produce huge large water hammer, cause the rotor counter-rotating, and it is loosening to produce rotor.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, a kind of double-suction pump impeller fixed structure is provided, this structure comprises front nut, snap ring and the back nut that is arranged at impeller one side, fixed structure is fixed on live axle and carries out spacing to impeller, while making it along with drive shaft turns, can guarantee that impeller can not produce axial float, from making whole impeller as rotor, can bear enough oppositely external force, and unlikely loosening.
The utility model purpose realizes being completed by following technological scheme:
A kind of double-suction pump impeller fixed structure, relate to impeller and live axle thereof, described impeller one side coordinates with described live axle flanged surface, it is characterized in that: described fixed structure is positioned at described impeller opposite side, described fixed structure comprises front nut, back nut and snap ring, described snap ring is between described forward and backward nut, the three is set in described live axle, wherein said forward and backward nut and described live axle form screw-thread fit, and described snap ring tightens spacing the cooperation respectively with between described live axle and described forward and backward nut.
Described live axle is provided with locking slot with described impeller, front nut, snap ring, the back nut place of matching, and between described snap ring and described live axle, spacing cooperation of chucking is by described locking slot and described snap ring inside lock mortice lock drive fit.
Internal ring wall surface one place's lug that the inboard locking plate of described snap ring is described snap ring.
Described snap ring is by the described snap ring outside locking plate and described spacing cooperation of forward and backward nut with spacing cooperation of the chucking between described forward and backward nut.
Described snap ring outside locking plate is that the uniform some lugs in external annulus surface of described snap ring constitute.
The utility model has the advantages that: simple in structure, cost of production is low; Can be widely used in the impeller locking of magna pump, be particularly useful for the water pump vane locking of Fraquent start.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of snap ring in the utility model;
Fig. 3 is the side view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model feature and other correlated characteristic are described in further detail, so that technician's of the same trade understanding:
As Figure 1-3, in figure, the 1-8 mark is respectively: impeller 1, front nut 2, snap ring 3, back nut 4, live axle 5, locking slot 6, inboard locking plate 7, outside locking plate 8.
Embodiment: as shown in Figure 1, the fixed structure in this enforcement is fixed on live axle 5 and is positioned at a side of impeller 1, in order to spacing to impeller 1 is carried out, avoids occurring axial float when along with live axle 5, rotating.Fixed structure in the present embodiment comprises front nut 2, snap ring 3 and back nut 4.Front nut 2, snap ring 3 and back nut 4 are set with on live axle 5, wherein before nut 2 with back nut 4, with live axle 5, form screw-thread fit respectively, snap ring 3 is between front nut 2 and back nut 4 and with both, form and tighten spacing the cooperation respectively.On the internal ring wall of snap ring 3, have the lug of a place as inboard locking plate 7, on external annulus, have uniform some lugs as outside locking plate 8, wherein inboard locking plate 7 coordinates with locking slot 6 lockings on live axle 5, and outside locking plate 8 forms spacing the cooperation with front nut 2, back nut 4 respectively.Live axle 5 is provided with locking slot 6 with impeller 1, front nut 2, snap ring 3, back nut 4 places of matching, and snap ring 3 is by being stuck in its inboard locking plate 7 among locking slot 6 with live axle 5, to form spacing cooperations of chucking.
The present embodiment is in the specific implementation: when mounted, the inboard locking plate 7 of snap ring 3 forms stuck with the locking slot of live axle 56 snap ring 3.On snap ring 3 external annulus, uniform some outsides locking plate 8 is stuck with front nut 2, the fastening formation of back nut 4 respectively, namely after front nut 2, snap ring 3 and back nut 4 install, these outside locking plates 8 are to intermittent nut 2, back nut 4 bendings forward alternately, so that outside locking plate 8 is stuck with groove or the inclined to one side silk of front nut 2 and back nut 4 respectively, snap ring 3 just can connect front nut 2 and back nut 4 securely like this.At this moment, no matter live axle 5 forward counter-rotatings can guarantee that impeller 1 can not produce loosening, from making whole rotor, can bear enough oppositely external force, and unlikely loosening.This structure can be widely used in the impeller locking of magna pump, is particularly useful for the water pump vane locking of Fraquent start.
Although with reference to design and the embodiment of accompanying drawing to the utility model purpose, describe in detail with above-described embodiment, but those of ordinary skills can recognize, under the precondition that does not break away from the claim limited range, still can make various improvement and conversion to the utility model, as: the kind of front nut 2 and back nut 4 and structure can require to replace with lock nut, hexagon nut etc. according to the fastening strength to impeller 1; The structure of snap ring 3 with and with the matching relationship between front nut 2 and back nut 4, can be set to that keyway is connected and buckle connection etc., therefore do not repeat one by one at this.
