At present, chinese patent literature discloses an impeller subassembly of deep-well pump, and grant bulletin number (CN207830208U), including the casing and all set up impeller and the stator in the casing, the stator be located the impeller top, the casing is tube-shape and casing both ends opening, the stator links firmly in casing upper end and casing up end and is higher than the stator up end, the casing lower extreme be connected with and be annular bottom plate, bottom plate outside middle part is equipped with the annular convex shoulder of protrusion in the bottom plate lateral wall.

The above structure is a simple impeller assembly for a deep well pump, which is not yet compact and perfect.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pair of guide vane assembly of deep-well pump has solved the not inseparable problem with perfect enough of prior art structure, has reached the advantage that improves the part and connect closely degree, provide the leak-stopping function.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a stator subassembly of deep-well pump, includes more than one guide vane group, and guide vane group includes the stator casing, is equipped with stator, impeller, its characterized in that from top to bottom in the stator casing in proper order: the upper end of stator casing is equipped with the throat portion, and this throat portion plug-in connection is fixed in the slot of stator, is equipped with the leak-stopping mechanism in the stator.

Preferably, the leakage stopping mechanism is: a first water collecting ring groove is arranged at the joint of the guide vane and the inner wall of the guide vane shell where the guide vane is located, and the first water collecting ring groove is connected with a water return pipeline arranged in the guide vane through a channel; the junction of this stator and the stator casing diapire of upside is equipped with water collection ring groove two, and this water collection ring groove two establishes the return water pipeline in this stator inside through the channel connection, and inside return water pipeline intercommunication stator casing.

Preferably, the water return pipeline comprises a water collecting annular hole, a sewer pipe is connected below the water collecting annular hole, and a section of S-shaped bent pipe is arranged on the sewer pipe.

Preferably, the guide vane is provided with a step, and the second water collecting ring groove is arranged at the lower side corner of the step.

Preferably, the first water collecting ring groove and the second water collecting ring groove are both arc-shaped grooves.

To sum up, the utility model discloses following beneficial effect has:

1. the utility model discloses can change the atress structure between the part, improve and fold the lifting surface area who presses between the part to guarantee the reliability that compresses tightly.

2. The utility model discloses can reach the effect of stator subassembly leak-stopping return water, the joint seam of each part all can not seep water in the subassembly.

3. The technical effects of improving the tightness and leakage prevention of the parts can be achieved through the characteristics.

Detailed Description

Examples

The utility model provides a stator subassembly of deep-well pump, includes more than one guide vane group 1, and guide vane group 1 includes stator housing 2, is equipped with stator 3, impeller 4, its characterized in that from top to bottom in the stator housing 2 in proper order: the upper end of stator casing 2 is equipped with throat portion 5, and this throat portion 5 is pegged graft and is fixed in the slot of stator 3, is equipped with the leak-stopping mechanism in the stator 3.

The leakage stopping mechanism is as follows: a water collecting ring groove I6 is arranged at the joint of the guide vane 3 and the inner wall of the guide vane shell 2, and the water collecting ring groove I6 is connected with a water return pipeline arranged in the guide vane through a channel; the junction of this stator 3 and the 2 diapire of stator casing of upside is equipped with two 8 of collecting water ring grooves, and this two 8 of collecting water ring grooves establish the return water pipeline in this stator through the channel connection, and inside return water pipeline intercommunication stator casing.

The first water collecting ring groove is connected with one channel, the second water collecting ring groove is connected with one channel, and when the guide vane assembly rotates, water flow can automatically rotate to permeate into the channels.

The water return pipeline comprises a water collecting annular hole 7, a sewer pipe 9 is connected below the water collecting annular hole 7, and a section of S-shaped bent pipe 10 is arranged on the sewer pipe.

The S-bend 10 is substantially "S" shaped by 90 degrees clockwise rotation, but is referred to in the industry by the term "S" bend. The S-shaped bent pipe is mainly used for avoiding water flow in the guide vane shell 2 from entering during rotation, and the effect that only water flows back and water does not enter is achieved.

The processing of leak stopping mechanism adopts the stator 3 piecemeal amalgamation of saying to form, specifically, divide into two, and the first piece is the interior piece of disc, and the second piece is the annular outer piece of circle, and the first piece inlays and establishes in the second piece, and wherein, two of catchment annular ring 7, downcomer 9 respectively account for half.

The guide vane 3 is provided with a step 11, and the second water collecting ring groove 8 is arranged at the lower side corner of the step.

The first water collecting ring groove 6 and the second water collecting ring groove 8 are both arc-shaped grooves.

Meanwhile, in order to ensure a certain confidentiality of the technology of the present invention, the applicant chooses to make a simplified schematic structural diagram of fig. 1 and 2, and a specific schematic structural diagram is disclosed in fig. 3.

The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any use of the present invention as a basis, in order to solve the same technical problems and achieve the same technical effects, the equivalent changes, equivalent replacements or modifications should be still included in the scope of the present invention.
