Abstract
The utility model relates to a telescopic submersible pump shaft, comprising a first flange (1) connected with a shaft flange, wherein a first sleeve (2) is connected to the first flange (1); a second sleeve (3) is movably sleeved on an excircle of the first sleeve (2); a second flange (4) connected with the shaft flange is connected to the second sleeve; the submersible pump shaft also comprises a connecting device and a sealing device; the first sleeve (2) and the second sleeve (3) are coaxially connected by the connecting device; the sealing device is used for sealing the joint between the first sleeve (2) and the second sleeve (3). An error can be generated by kinds of reasons when the shaft is arranged or a pump body is placed, and by adopting the submersible pump shaft, the sleeve can generate a certain displacement in an axial direction to correct the error by adjusting a bolt (7); a gland (10) is connected with a second adapter ring (6) through the bolt and used for pressing filler (9), so that the sealing property of the submersible pump shaft is good.
Description
Technical field
The utility model relates to a kind of submersible pump, is specifically a kind of submersible pump pit shaft.
Background technique
Submersible pump is the visual plant of deep-well water lift, the whole unit work that pulls the plug during use.Submersible pump pit shaft is the vitals of submersible pump, and pit shaft comprises pit shaft and well-sinking in the prior art, and upper well-sinking is to connect by flange.Submersible pump will often keep in repair because of being operated in easy damage in water, and the maintenance of submersible pump need to hang out the water surface submersible pump to be carried out on the coast, and submersible pump generally can often be dismantled and assemble like this.And generally can produce error due to a variety of causes when pit shaft being installed and placing the pump housing, this carries out regulating error while just seeming installation pit shaft and the placement pump housing very important, and well-sinking is very inconvenient because error makes to assemble on shaft structure of the prior art, and its sealing effect of joint is also bad.
Model utility content
Technical problem to be solved in the utility model is: the submersible pump pit shaft that a kind of easy fitting tight is good is provided.
For solving the problems of the technologies described above the utility model, provide a kind of submersible pump pit shaft, it comprises the first flange for being connected with pit shaft flange, on the first flange, be connected with the first sleeve, on the first sleeve cylindrical, activity is sheathed with the second sleeve, on the second sleeve, be connected with the second flange for being connected with pit shaft flange, submersible pump pit shaft also comprises the first sleeve with the second quill to the connection set being connected with for sealing the seal arrangement of the first sleeve and the second sleeve joint.
Compared with prior art, the utility model has the advantage of: when pit shaft being installed or place pump housing generation error, the utility model can be by regulating the bolt on two connecting rings to make sleeve axially have certain displacement to move with rectification error.Gland is connected with the second sleeve by bolt and compresses filler makes sealability of the present utility model fine.
The pit shaft flange that described submersible pump pit shaft is connected with the first flange is upper pit shaft flange, and the pit shaft flange being connected with the second flange is well-sinking flange, quick by flange connection convenient disassembly between pit shaft.
The structure of described connection set is to be provided with the first connecting ring on the excircle of the first sleeve, on the excircle of the second sleeve, be provided with the second connecting ring, on two connecting rings, be equipped with that quantity equates and through hole one to one, two connecting rings are bolted, and this connection set can regulate pit shaft.
As being fixed with the 3rd sleeve between preferably described submersible pump pit shaft the second connecting ring and the second sleeve, add the 3rd sleeve and be convenient to the sealing between the first sleeve and the second sleeve.
The structure of described seal arrangement is that stuffing box packing is placed in the space between the 3rd sleeve and the second sleeve and the first sleeve, the gland that it is " L " shape that described submersible pump pit shaft also comprises for press seal filler and cross section, the front end of gland horizontal expansion part is pressed in space and makes sealability of the present utility model fine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In Fig. 1: 1 first flange, 2 first sleeves, 3 second sleeves, 4 second flanges, 5 first connecting rings, 6 second connecting rings, 7 bolts, 8 the 3rd sleeves, 9 stuffing box packing, 10 glands.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, a pit shaft, the first sleeve 2 that comprise the first flange 1 for being connected with pit shaft flange, is connected with the first flange 1 be enclosed within the second sleeve 3 on the first sleeve 2 cylindricals, for the second flange 4, the submersible pump pit shaft being connected with pit shaft flange, also comprise the first sleeve 2 with the axial connection set being connected of the second sleeve 3 with for sealing the seal arrangement of the first sleeve 2 and the second sleeve 3 joints.
Described submersible pump pit shaft is because its sleeve can also can be called telescopic submersible pump pit shaft axially there being certain displacement to move, the first flange 1 is connected with the flange of upper pit shaft, the second flange 4 is connected with the flange of well-sinking, this telescopic pit shaft has just been connected with upper well-sinking like this, described connection set is to be provided with the first connecting ring 5 on the excircle of the first sleeve 2, on the excircle of the second sleeve 3, be provided with the second connecting ring 6, on two connecting rings, be equipped with that quantity equates and through hole one to one, two connecting rings connect by bolt 7.Connecting ring on the first sleeve 2 and the second sleeve 3 can be also a plurality of contiguous blocks that distribute vertically, is provided with that quantity equates and through hole one to one on two contiguous blocks, and two contiguous blocks connect by bolt 7.As being fixed with the 3rd sleeve 8 between preferably described submersible pump pit shaft the second connecting ring 6 and the second sleeve 3.The structure of described seal arrangement is that stuffing box packing 9 is placed in the space between the 3rd sleeve 8 and the second sleeve 3 and the first sleeve 2, the gland 10 that it is " L " shape that described submersible pump pit shaft also comprises for press seal filler 9 and cross section, the front end of gland horizontal expansion part is pressed in space.On connecting ring on gland 10 and the second connecting ring 6, be equipped with that quantity equates and through hole one to one, two connecting rings are bolted.When pit shaft being installed or place pump housing generation error, can make sleeve axially have certain displacement to move with rectification error by adjusting bolt 7.Gland is connected with the second sleeve by bolt and compresses filler makes sealability of the present utility model fine.
