Description

Radial guide-vane Spit Section is opened before one

Technical field

The utility model relates to multistage pump, opens radial guide-vane Spit Section before being specifically related to one.

Background technique

Open before multistage pump to open before radial direction is provided with radial Spit Section and before open radial final stage stator, and before open radial Spit Section with before to open radial final stage stator be all separate to carry out casting (see Fig. 1), then when assembling, then by front open radial final stage stator and before open radial Spit Section and fit together.

Like this, when generating, the cost producing material can be very high, adds manufacturing procedure, reduce working efficiency, also greatly reduce assembly precision.

Model utility content

The utility model in order to solve above-mentioned before open radial Spit Section and front to open cost of production that radial final stage stator exists high and reduce the problems such as assembly precision, thus before one is provided, open radial guide-vane Spit Section.

For achieving the above object, the technical solution of the utility model is as follows:

Radial guide-vane Spit Section is opened before one, open before described to open before radial guide-vane Spit Section comprises radial final stage stator and before open radial Spit Section, open before described radial Spit Section and before open radial final stage stator cast solid, open before described on radial guide-vane Spit Section and be not provided with front shroud, open radial Spit Section before described and comprise the first guide edge, the second guide edge and the 3rd guide edge, form the passage that spues between first guide edge and the second guide edge, open before described radial Spit Section by the second guide edge and the 3rd guide edge and before open radial final stage stator cast solid.

In a preferred embodiment of the present utility model, open radial guide-vane Spit Section before described and adopt stainless steel casting to form.

By technique scheme, the beneficial effects of the utility model are:

The utility model by open before traditional radial final stage stator and before open radial Spit Section and be cast as one, and front shroud is not set, which reduces cost of production and improve assembly precision.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is sectional view of the present utility model.

Embodiment

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

See Fig. 2, open before the one that the utility model provides to open before radial guide-vane Spit Section mainly comprises radial Spit Section 100 and before open radial final stage stator 200.

Before open radial Spit Section 100 and front open radial final stage stator 200 cast solid, thus open radial guide-vane Spit Section before being formed.

Before open radial Spit Section 100 and front to open radial final stage stator 200 specifically integral by die casting, and when casting, front shroud is not set, because the utility model is overall by being cast into one, so do not need to arrange front shroud.

Being directly cast all-in-one-piece owing to front opening radial Spit Section 100 with front opening radial final stage stator 200, just having saved production material, having reduced cost of production, having also improved assembly precision simultaneously.

Before open radial Spit Section 100 and be provided with the first guide edge 110, second guide edge 120 and form the passage 140 that spues between the 3rd guide edge 130, first guide edge 110 and the second guide edge 120.

In the past first guide edge 110 and the second guide edge 120 be convenient to open before liquid that radial final stage stator 200 flows out flow into open on radial Spit Section 100.

First guide edge 110 with front open radial final stage stator 200 and do not contact, the Vertical direction at the first guide edge 110 top is provided with boss 111, is provided with contact jaw 112 in the bottom of the first guide edge 110.

Second guide edge 120, and front opens radial final stage stator 200 cast solid, and its global sections is spoon shape, is convenient to like this to open before liquid that radial final stage stator 200 flows out flow into open on radial Spit Section 100 in the past.

The Vertical direction at the second guide edge 120 top is also provided with boss 121, and boss 111 on boss 121 and the first guide edge 110 is symmetrical.

The tail end of the second guide edge 120 is provided with contact jaw 122, and the second guide edge 120 is front being opened on radial final stage stator 200 by contact jaw 122 vertical casting.

The fixed edge 123 that cross section is L shape is also provided with bottom the second guide edge 120.

3rd guide edge 130, and front opens radial final stage stator 200 cast solid, and be provided with contact jaw 131 on the 3rd guide edge 130 top, the 3rd guide edge 130 is front being opened on radial final stage stator 200 by contact jaw 131 vertical casting.

3rd guide edge 130 is provided with the fixed edge 132 of L shape, and the fixed edge 123 on fixed edge 132 and the second guide edge 120 is symmetrical.

The utility model by front driving the second guide edge 120 on radial Spit Section 100 and the 3rd guide edge 130 and front opening radial final stage stator 200 cast solid, thus front will be opened radial Spit Section 100 and front open radial final stage stator 200 cast solid.

The utility model adopts stainless steel casting to form, very corrosion-resistant, durable, improves working life.

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, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
