Abstract
The utility model relates to an axial combined impeller and guide blade structure, and belongs to the filed of submersible centrifugal electric pump. The guide blades are arranged on a blade wheel, and have same diameter and definite conicity. As the radial water outlet of the guide blades are changed into the axial water outlet, the radial dimension is small, the structure is compact, and the utility model is convenient for processing and manufacturing the combination with any stage.
Description
The utility model patent is a kind of impeller and guide vane structure of axial combination, belongs to the submersible centrifugal electric pump field.
The impeller and the guide vane structure of the present submersible centrifugal electric pump that uses, water is to flowing to, by the water chute of stator by impeller shaft, radially flow out, flow in the pump impeller of next stage pump or by pipe joint again and flow in the lifting pipe, impeller and the guide vane structure of existing submersible centrifugal electric pump are loose, stator overcurrent part to the greatest extent cun greatly, require the hole diameter of use big, limited the using scope of water pump, and materials are many, processing time consuming, the inside hydraulic loss of pump is bigger, has reduced the efficient of pump.
In order to overcome the deficiency of above-mentioned water pump vane and guide vane structure, the utility model patent spy has proposed a kind of water pump vane and guide vane structure of axial combination.
The impeller of the axial combination of the utility model and guide vane structure mainly are made up of impeller, stator, shell.Impeller is identical with the stator diameter, and the edge has certain tapering.
The impeller of this axial combination and the working procedure of guide vane structure are: water axially flows into stator by the impeller outer edge of pump, water chute by stator, water outlet in the middle of the water that impeller is thrown away is pooled to axially flows in the pump impeller of next stage pump or by pipe joint again and flows in the lifting pipe.
This is the impeller and the guide vane structure of combination axially, is a semi-enclosed pump impeller, and the stator water outlet is by radially changing into axially, and stator overcurrent part physical dimension is reasonable, and the inside hydraulic loss of pump reduces, and has increased the efficient of pump.Have tapering on impeller, the stator, making refluxes reduces, and has increased the flow of pump, this device radial dimension is little in addition, is half of former submersible centrifugal electric pump impeller and guide vane structure volume approximately, compact structure, saved metallic material morely, also be convenient to process, the combination of manufacturing and any number of stages.
Fig. 1 is the impeller of this axial combination and the work schematic representation of guide vane structure
Embodiment: (see figure 1)
The impeller of the axial combination of the utility model and guide vane structure mainly are made of impeller 1, stator 2, shell 3, and stator is contained in above the impeller, and external diameter is identical.All have certain taper, constitute a semi-enclosed pump impeller.
