Abstract
The utility model relates to a large -scale pump diffuser structure, barrel in outer barrel of multi -disc guide blade, stator and stator, all guide blades all weld the stator outside in barrel and the stator between the barrel, form the diffuser structure, and wherein a slice in the guide blade be the guide blade thicker than remaining guide blade, thereby cast the lubrication conduit who has the external clear water of connection to protect the guide bearing at the back of the guide blade of this thickening. The utility model discloses the guide blade is cast alone to the processing of accessible machining center can guarantee that the blade molded lines is the same with the designing requirement, and the guarantee efficiency is thickeied a slice guide blade back simultaneously and is cast lubrication conduit, through the external clear water protection bearing of this pipeline, casts the guide blade alone, and the mould reduces greatly, and the die sinking expense reduces, and the welding piece has also improved appearance quality, has guaranteed the shaping rate.
Description
Technical field
The utility model relates to a kind of diffuser structure, and being specifically related to a kind of guide vane can cast separately, thickeies the magna pump diffuser structure of a slice guide vane back side casting lubricating pipe simultaneously.
Background technique
Fig. 1 is the overall structure schematic diagram of pump diffuser structure common at present.As seen from Figure 1: the diffuser structure of existing large-sized vertical-type axial-flow pump water pump is cast inblock form, and material is cast iron or cast steel.Namely the guide vane 2 in Fig. 1, stator outer cylinder body 1 and stator inner barrel 3 cast inblock.But this structure Problems existing is: (1), diffuser belong to large thin-wall element, casting difficulty is large, easily produces reject.(2), cast-in-block diffuser due to guide vane be curved surface, guide vane cannot be processed between two cylindrical shells.(3), diffuser is oversize, and Integral casting die is comparatively large, not easily casts, and casting outward appearance is general.(4), original structure do not design lubricating pipe, cannot external lubrication with clean water protection guide bearing.
Model utility content
For the problems referred to above, main purpose of the present utility model is to provide a kind of guide vane to cast separately, thickeies the magna pump diffuser structure of a slice guide vane back side casting lubricating pipe simultaneously.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of magna pump diffuser structure; described magna pump diffuser structure comprises multi-disc guide vane; described magna pump diffuser structure also comprises stator outer cylinder body and stator inner barrel; all guide vanes are all welded between stator outer cylinder body and stator inner barrel; form diffuser structure; wherein a slice in guide vane is the guide vane thicker than remaining guide vane, is cast with connects extraneous clear water thus the lubricating pipe of protection guide bearing at the back side of the thick guide vane of this sheet.
In specific embodiment of the present utility model, the sheet number of described guide vane is 5-7 sheet.
Positive progressive effect of the present utility model is: the magna pump diffuser structure that the utility model provides has the following advantages: the utility model guide vane is cast separately; and by Cutter Body Processing with Machining Center; can ensure that vane type line is the same with designing requirement; guaranteed efficiency; thicken a slice guide vane back side casting lubricating pipe simultaneously; by this pipeline extraneous clear water protection bearing; independent casting guide vane; mould reduces greatly; die sinking expense reduces; weldment also improves appearance quality, ensure that molding rate.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of pump diffuser structure common at present.
Fig. 2 is overall structure schematic diagram of the present utility model.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 2 is overall structure schematic diagram of the present utility model.As shown in Figure 2; the utility model comprises multi-disc guide vane 2, stator outer cylinder body 1 and stator inner barrel 3; all guide vanes 2 are all welded between stator outer cylinder body 1 and stator inner barrel 3; form diffuser structure; wherein a slice in guide vane 2 is the guide vane (being labeled as 201 of thickening) thicker than remaining guide vane, and the back side of the guide vane thickeied at this sheet is cast with and connects extraneous clear water thus the lubricating pipe 4 of protection guide bearing.
In concrete enforcement of the present utility model, the sheet number of guide vane 2 generally elects 5-7 sheet as.
The utility model entered Strength co-mputation; magna pump diffuser is mainly divided into guide vane and stator outer cylinder body and stator inner barrel three part; three parts are fixed together by welding; thicken a slice guide vane back side casting lubricating pipe simultaneously; be connected with extraneous clear water by this pipeline; thus protection bearing, improve the easily damaged parts life-span.Independent casting guide vane, reduces mould size, reduces casting difficulty, is easy to shaping, and before welding, guide vane surface can also be processed by machining center, improves surface accuracy, and then improves hydraulic efficiency.Diffuser structure after improving, namely improves efficiency, also extends bearing working life, improves product appearance quality simultaneously.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. a magna pump diffuser structure; described magna pump diffuser structure comprises multi-disc guide vane; it is characterized in that: described magna pump diffuser structure also comprises stator outer cylinder body and stator inner barrel; all guide vanes are all welded between stator outer cylinder body and stator inner barrel; form diffuser structure; wherein a slice in guide vane is the guide vane thicker than remaining guide vane, is cast with connects extraneous clear water thus the lubricating pipe of protection guide bearing at the back side of the thick guide vane of this sheet.
2. magna pump diffuser structure according to claim 1, is characterized in that: the sheet number of described guide vane is 5-7 sheet.
