Background technique
The deep well submerged pump major part of prior art is plastics stator and impeller, and single-stage impeller lift is low, and the stator inner space big efficient of lossy is low, and front shroud of impeller and runner welding blade are difficult for firmly, concentricity is also bad, particularly multistage high pressure is easily to split; Back shroud of impeller and the cooperation of stator are whole combining that friction is big, also increased loss during noise Datong District, and under anhydrous situation operation impeller and stator quick-wearing very, reduce the life-span greatly.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provides a kind of simple in structure, and is easy to adjust, reduces cost the impeller and the guide vane structure of the novel deep-well pump of increasing work efficiency.
The utility model is realized in the following way:
A kind of impeller of deep-well pump and guide vane structure comprise impeller 1, stator 2, stator lid 3, and impeller 1 is located in the stator 2, and stator lid 3 is located on the stator 2; It is characterized in that: impeller (1) comprises that front and rear cover plate, front shroud (15) are provided with blade groove (13), back shroud (16) is provided with runner blade 14, and blade 14 is the periphery of dispersion shape distribution wheel shaft 11; Blade 14 and wheel shaft 11 close ends are provided with choma 6, and wheel shaft 11 is arranged with the collar 7 with the joint of stator 2;
Described stator 2 is a chamber shape, and its inwall is provided with five equilibrium cut water 21; Cut water 21 is connected with runner on the stator 2;
Be embedded with wear ring 8 on the described stator lid 3, described wear ring 8 contacts with choma 6 on the blade 12.
Choma 6 of the present utility model, the collar 7, wear ring 8 all adopt corrosion resistant plate to be made.
The utility model is provided with cut water 21 on stator 2, with impeller 1 Spielpassung, liquid just enters stator 2 cut waters 21 runners from impeller 1 outlet, stops liquid circulation loss in stator 2; Improve the single-stage lift of deep-well pump, shortened the entire length of deep-well pump; Reduce thereby reduced the deep-well pump cost of production, the reliability of deep-well pump improves, and efficient also improves.
The runner water outlet 9 of the utility model impeller 1 and cut water 21 Spielpassung on the stator 2 improve deep-well pump single-stage lift and flow; Be bumped into the abrasion-proof stainless steel collar 7 of die mould on the impeller 1, reduce impeller 1 and stator 7 friction areas, improve wear resistance and stability greatly.
The abrasion-proof stainless steel ring 8 that the utility model is bumped in the center of stator lid 3 matches with choma 6 on the impeller 1, improves wear resistance and stability greatly, lowers stator 2 internal height, improves single-stage lift.
In sum, the utility model is a kind of simple in structure, easy to adjust, reduces cost, the impeller and the guide vane structure of the novel deep-well pump of increasing work efficiency.
