The pump body of submerged electric pump for well comprises ashell, wherein a turbine housing is fixedly connected in the shell, a guide vane is arranged inside the turbine housing, and the turbine housing and the guide vane form an integral structure. The pump body of submerged electric pump for well has the advantages of simple structure, abrasion resistance, high working efficiency and the like.
Description
Technical field
The utility model belongs to the pump technical field, relates to a kind of pump housing, particularly a kind of well pump housing of Submerged Motor Pumps.
Background technique
At present, the well Submerged Motor Pumps is the bigger product of demand in the pump series products, and industrial and mining enterprise, high-floor feedwater, deep-well water lift, agricultural irrigation, domestic water, the conveying of change liquid etc. are played a positive role.General well mostly comprises the pump housing, is arranged on pump shaft, impeller and motor in the pump housing with Submerged Motor Pumps, and pump shaft links by shaft joint and rotating shaft, and the pump housing and motor link.The pump housing generally is made up of volute and stator, and at present, well is not an integral structure with the volute and the stator of the Submerged Motor Pumps pump housing, and such pump body structure is complicated, is subjected to the wearing and tearing of current easily, serious even working efficiency that influence well usefulness Submerged Motor Pumps.
Summary of the invention
The purpose of this utility model is to have above-mentioned problem at prior art, and the pump housing of a kind of well of simple in structure, high working efficiency with Submerged Motor Pumps is provided.
The purpose of this utility model can realize by following technical proposal: a kind of well comprises housing with the pump housing of Submerged Motor Pumps, is fixed with volute in housing, and described volute inboard has stator, it is characterized in that, described volute and stator are integral structure.
This well is designed to integral structure with the pump housing of Submerged Motor Pumps with stator and volute, reduces the diffusance of stator, thereby reduces divergence loss.The gap of control housing, thus disc friction reduced.Reduce the vane inlet angle, thereby reduce the loss of import bump.
With in the pump housing of Submerged Motor Pumps, described volute comprises the seat of honour, following, blade rack, loam cake and lower cover at above-mentioned well.Above-mentioned stator is connected with following by the mode and the seat of honour of welding, and mode and blade rack, loam cake and the lower cover by spot welding is connected again.Stator is supported by blade rack, and blade rack can also be played a supporting role to whole spiral case.
With in the pump housing of Submerged Motor Pumps, described blade rack comprises bezel ring, and support base ring on the support at above-mentioned well, and bezel ring, is connected on above-mentioned stator and the support.
With in the pump housing of Submerged Motor Pumps, described volute and stator all adopt stainless steel material to make at above-mentioned well.
Compared with prior art, this well is designed to integral structure with the pump housing of Submerged Motor Pumps with stator and volute, reduces the diffusance of stator, thereby reduces divergence loss, effectively raises the working efficiency of well with Submerged Motor Pumps.
Description of drawings
Fig. 1 is the structural representation of this well with the pump housing of Submerged Motor Pumps.
Fig. 2 is the structural representation of this well with the stator of the pump housing of Submerged Motor Pumps.
Among the figure, 1, housing; 2, stator; 3, the seat of honour; 4, following; 5, blade rack; Bezel ring, on 5a, the support; 5b, support base ring; 6, loam cake; 7, lower cover.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this well comprises housing 1 with the pump housing of Submerged Motor Pumps, is fixed with volute in housing 1, and described volute inboard has stator 2, and described volute and stator 2 are integral structure, and volute and stator 2 all adopt stainless steel material to make.
Particularly, volute comprises the seat of honour 3, following 4, blade rack 5, loam cake 6 and lower cover 7, and above-mentioned stator 2 is connected with following 4 with the seat of honour 3 by the mode of welding, and mode and blade rack 5, loam cake 6 and the lower cover 7 by spot welding is connected again.Blade rack 5 comprises support loam cake 6 ring 5a and support base ring 5b, and above-mentioned stator 2 is connected with support loam cake 6 ring 5a.Stator 2 is supported by blade rack 5, and blade rack 5 can also be played a supporting role to whole spiral case.
In other words, as shown in Figure 1, stator 2 with the seat of honour 3, weld together for following 4, spot-welded together with support loam cake 6 ring 5a, loam cake 6 and lower cover 7 again, formed a volute like this, such volute has reduced the diffusance of stator 2, has improved the working efficiency of electric pump like this.
This well is designed to integral structure with the pump housing of Submerged Motor Pumps with stator 2 and volute, reduces the diffusance of stator 2, thereby reduces divergence loss.The gap of control housing 1, thus disc friction reduced.Reduce stator 2 inlet angles, thereby reduce the loss of import bump, and then improved the working efficiency of well with Submerged Motor Pumps.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used 1, housing morely; 2, stator; 3, the seat of honour; 4, following; 5, blade rack; Bezel ring, on 5a, the support; 5b, support base ring; 6, loam cake; 7, term such as lower cover, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
