Above-mentioned impeller chimney end axle sleeve 5 comprises a plastic supporting pieces 51 shown in Figure 10 A and 10B, and it has a sleeve end detorsion structure 53 shown in Figure 10 A-10C.Plastic supporting pieces 51 surrounded one rubber bushing 52 described rotor chamber end axle sleeves 6 comprise a plastic supporting pieces 61, and plastic supporting pieces 61 surrounded one rubber bushing 62, and its structure is shown in Fig. 8 and 9.
As mentioned above, the detorsion structure characteristic of described improved impeller unit 2 can stop the impeller counterrotating, is not rotated in the forward but do not hinder impeller.Sleeve end detorsion structure 53 on the described impeller chimney end axle sleeve 5 is defined as a geared assembly, and this geared assembly comprises a pair of inclined-plane 531 and a pair of vertical face 532 of keeping out.Described each vertically keep out face 532 and be one and be located at the impeller chimney end axle sleeve 5 end faces locational axial plane of halving.The concrete structure of above-mentioned sleeve end detorsion structure 53 is shown in Figure 10 A, 10B and 10C, and described as seen from the figure two vertically to keep out face 532 are coplanes.Above-mentioned each inclined-plane 531 is that its plane normal and impeller chimney end axle sleeve 5 axis angles are about 15 ° face.
Similarly, the impeller end detorsion structure on the described impeller 42 421 is a pair of inclined-plane 4211 and a pair of vertical face 4212 of keeping out.Described each vertically keep out face 4212 and be one and be located at the impeller 42 end faces locational axial plane of halving.The concrete structure of above-mentioned impeller 42 is shown in Figure 12 A, 12B and 12C, and described as seen from the figure two vertically to keep out face 4212 are coplanes.Above-mentioned each inclined-plane 4211 is that its plane normal and leaf impeller 42 axis angles are about 15 ° face.
When impeller 42 counterrotatings, the inclined-plane 4211 of above-mentioned impeller 42 ends will with the inclined-plane 531 of impeller chimney end axle sleeve 5 near joining, when this situation occurring, because the face of vertically keeping out 532 of impeller chimney end axle sleeve 5 ends is kept out mutually with the vertical face 4212 of keeping out of impeller 42 ends, impeller 42 is limited around rotor shaft 3 further counterrotatings.Yet, when the inclined-plane 531 of the inclined-plane 4211 of impeller 42 ends (shown in Figure 12 A, 12B and 12C) and impeller chimney end axle sleeve 5 when joining, if this moment, impeller 42 was rotated in the forward, the inclined-plane 531 of the 4211 relative impeller chimney end axle sleeves 5 in the inclined-plane of impeller 42 ends is transferred or is slided, and can not produce great friction or obstruction.
As mentioned above, described impeller 42, vane rotor link 43 and permanent magnet rotor 41 its each all are provided with a circle perforation at axial center, and they are fixedly connected on and form vane rotor corotation body 4 simultaneously.Described vane rotor corotation body 4 is supported and can be rotated freely around rotor shaft 3 by rotor shaft 3.Further, its more detailed description is as follows, and described vane rotor corotation body 4 can move axially along rotor shaft.The length of described rotor shaft is longer with the length sum of impeller chimney end axle sleeve 5 and rotor chamber end axle sleeve 6 than vane rotor corotation body 4, like this when vane rotor corotation body 4 is in position near rotor chamber end axle sleeve 6, the gap is defined as X (as shown in figure 14) between impeller chimney end axle sleeve 5 and the impeller 42, She Ji gap makes vane rotor corotation body 4 equal gap (that is, distance equals X) along the axially movable distance of rotor shaft like this.
Particularly, by being set, rotor shaft 3 makes: when vane rotor corotation body 4 is in position near rotor chamber end axle sleeve 6, distance definition between impeller chimney end axle sleeve 5 and the impeller 42 is a gap, this gap length is approximately and is less than 0.1 inch, or be approximately between 0.1～0.3 inch, or be approximately between 0.3～0.5, or be approximately between 0.5～0.7.In other embodiments, rotor shaft 3 is set to make: when vane rotor corotation body 4 is in position near rotor chamber end axle sleeve 6, distance definition between impeller chimney end axle sleeve 5 and the impeller 42 is a gap, this gap length is approximately and is less than rotor shaft 3 diameters, or be approximately between one to two rotor shaft 3 diameters, or be approximately between two to four rotor shaft 3 diameters, or be approximately between four to six rotor shaft 3 diameters.Yet the length of rotor shaft 3 will can not be limited, and this rotor shaft 3 can be any Rational structure structure that is suitable for 2 runnings of this impeller unit in the existing public technology.
Figure 15-17 has enumerated the just transhipment row and the counter-rotating operation of this improved impeller unit 2.As described in preliminary matter, impeller 42 is driven by a pump housing that is connected with power supply 1.When submersible pump body 1 is connected power supply, in the process of starting, the magnetic field that the stator coil 14 in the pump case 12 will produce a change at random.At this moment, be located at field drives impeller 42 rotations of the above-mentioned variation of permanent magnet rotor 41 responses on rotor chamber 16 inner rotor shafts 3.As mentioned above, impeller 42 is connected with vane rotor link 43, and this vane rotor link 43 is connected with permanent magnet rotor 41 again, and by such setting, impeller 42 shells are followed permanent magnet rotor 41 and rotated together and move.
Described improved impeller unit has the ability that stops impeller 42 counterrotatings.If impeller 42 allows counterrotating, the impeller 42 of then this rotation will produce flow-disturbing, reduces the flow stability of impeller unit and the efficient of water pump and impeller unit greatly.Shown in Figure 16 and 17, when the impeller counterrotating, water will be flowed into by water outlet staving 21, water produces a reaction force to the blade of impeller 42, this opposition is delivered to whole vane rotor corotation body 4, drives impeller rotor corotation body 4 moves to impeller chimney end axle sleeve 5, and here, the face of vertically keeping out 532 of impeller chimney end axle sleeve 5 ends and impeller 42 ends vertical keeps out that face 4212 intermeshes and the further counterrotating that stops impeller 42.More specifically, when the impeller counterrotating, vane rotor corotation body 4 moves along rotor shaft, makes impeller 42 near impeller chimney end axle sleeve 5, as shown in figure 17.
When vane rotor corotation body 4 continued counterrotating, the face of vertically keeping out 4212 of impeller 42 ends contacted and crossover with the vertical face 532 of keeping out of impeller chimney end axle sleeve 5 ends.Because this structure of mounting bracket 212 stops 5 counterrotatings of impeller chimney end axle sleeve, though this moment 16 li of rotor chamber magnetic field counterrotating power is provided constantly for vane rotor corotation body 4, described impeller 42 still is prevented from further counterrotating.Therefore, before current direction became forward, above-mentioned impeller 42 was prevented from rotation, thereby stoped and not wish to take place liquid and be back in the impeller chimney by water outlet 211.According to the characteristics of submersible pump, after after a while, it is stable that the direction of Ac and magnetic field will become.After magnetic field is stable, the pump housing 1 will impel permanent magnet rotor 41 to be rotated in the forward.
As a reference, explanation water is enumerated by the reverse inflow of water intake staving in the right of the substantially horizontal arrow points above the vane rotor corotation body 4 in Figure 16.And among Figure 16, explanation vane rotor corotation body 4 driven directions are enumerated on the substantially horizontal arrow points left side in the vane rotor corotation body 4, and it is the result of the reaction force of flow action on impeller 42 blades.Curved arrow among Figure 16 is represented the direction of counterrotating.
This moment, when the pump housing 1 applied a moment of torsion that is rotated in the forward on permanent magnet rotor, vane rotor corotation body 4 was rotated in the forward generation on the contrary.When this takes place, the inclined-plane 531 of the 4211 relative impeller chimney end axle sleeves 5 in the inclined-plane of impeller 42 ends slides, the face of vertically keeping out 4212 of impeller 42 ends separates with the vertical face 532 of keeping out of impeller chimney end axle sleeve 5 ends like this, separately crossover or do not stop that vane rotor corotation body 4 is rotated in the forward not.When impeller 42 was rotated in the forward, vane rotor corotation body 4 was driven and leaves wheel cover end axle sleeve 5.Increase along with vane rotor corotation body 4 rotational speeies, water will flow out impeller chimney 2 through water outlet 211, it has additionally applied an acting in opposition on the blade of impeller 42 simultaneously, makes rotor corotation body 4 further leave impeller chimney end axle sleeve 5, makes impeller 42 not contact with impeller chimney end axle sleeve 5.The horizontal arrow of lower floor among Figure 15 represents that when vane rotor corotation body 4 is rotated in the forward shown in the curved arrow of Figure 15, water acts on the reaction force direction on impeller 42 leaves.When this takes place, will produce gap as described above between impeller chimney end axle sleeve 5 and the impeller 42.Described gap is enough big, make impeller 42 ends inclined-plane 4211 and vertically keep out face 4212 and do not contact with the inclined-plane 531 and the vertical face 532 of keeping out of wheel cover end axle sleeve 5 separately.
In other embodiments, sleeve end detorsion structure 53 can be defined as comprising one to eight vertically keep out face 532 and with the inclined-plane 531 of its respective number, each inclined-plane 531 is approximately with respect to the radial plane inclination and is less than 15 °, or be approximately between 15 ° to 20 °, or be approximately between 20 ° to 45 °.And impeller chimney end axle sleeve 5 and impeller 42 structures are respectively equipped with the vertical vertical face 4212 of keeping out of keeping out face 532 and impeller 42 ends of one, three or four impeller chimney end axle sleeve 5 end more specifically, and the inclined-plane 4211 of the inclined-plane 531 of one, three or four impeller chimney end axle sleeve 5 end and impeller 42 ends, shown in its concrete structure Figure 18 A, 18B, 19A, 19B, 20A and the 20B.Alternatively, described sleeve end detorsion structure 53 is for can stop impeller 42 counterrotatings and not hinder the arbitrary structures scheme that it is rotated in the forward.For example, in another embodiment, the inclined-plane can be rough curved surface, but it has certain inclination with respect to the radial plane substantially.
In other embodiments, described impeller 42 can be defined as comprising one to eight vertically keep out face 4212 and with the inclined-plane 4211 of its respective number, each inclined-plane 4211 is approximately with respect to the radial plane inclination and is less than 15 °, or be approximately between 15 ° to 20 °, or be approximately between 20 ° to 45 °.Alternatively, described impeller 42 is for can stop impeller 42 counterrotatings and not hinder the arbitrary structures scheme that it is rotated in the forward.For example, in another embodiment, the inclined-plane can be rough curved surface, but it has certain inclination with respect to the radial plane substantially.
