Abstract

The utility model relates to an axial space guide vane which comprises an outer casing (1), a guide vane body (2), an inner casing (3), a water guide taper (4) and an outer tube (5). The punch molded guide vane body (2) is welded between the outer casing (1) and the inner casing (3), the water guide taper (4) is connected with the inner casing (3), the outer casing (1) is connected with the outer tube (5), and the water guide taper (4) is disposed in the outer tube (5). According to the axial space guide vane, defects of multiple machining consumables, high costs and the like because traditional space guide vanes are space twisty vanes of complicated structures are overcome, the outer casing and the inner casing are connected with the outer tube and the water guide taper respectively to form a whole guide vane part after the punch molded guide vane is welded with the outer casing and the inner casing, and the guide vane part has effects of effectively reducing the liquid flow speed, eliminating the liquid rotational component, converting velocity energy into pressure energy, leading the liquid flow out and the like. The axial space guide vane has the advantages of being simple to manufacture, low in cost, small in hydraulic loss and high in efficiency.

Description

A kind of axial space stator

Technical field

The utility model relates to a kind of guide vane structure of pump, relates in particular to a kind of manufacturing simply, and cost is low, and hydraulic loss is little, the axial space stator that efficient is high.

Background technique

Stator is to use a very general class pumping chamber in all kinds of pumps, it has the flow stream velocity of reduction, eliminates the liquid in rotation component, with speed can be converted to the pressure energy, with effects such as the liquid conductance go out.At present, traditional spatial guide blade is used for well pump and guide vane mixed flow pump more, and its blade is spatial warping because complex structure is used for casting more, and casting with process that institute's consumption material is many, cost is high.

The model utility content

The utility model provides a kind of manufacturing simple, and cost is low, and hydraulic loss is little, the axial space stator that efficient is high, and its purpose is to solve traditional spatial guide blade complex structure, and the processing consumptive material is many, problems such as cost height.

The utility model solves above-mentioned technical problem by following technical proposals:

A kind of axial space stator, comprise shell, guide vane, inner casing, water guide cone and outer tube, the described guide vane after the impact briquetting is welded between described shell and the inner casing, and described water guide cone links to each other with inner casing, described shell links to each other with outer tube, and described water guide cone is positioned at described outer tube.

Described guide vane is one section circular arc type thin plate or is that one section one end is the circular arc type thin plate that the other end is the special-shaped thin plate of rectangular thin plate and integral one-step molding.

Positive progressive effect of the present utility model is: the blade that it is spatial warping that the utility model has overcome traditional spatial guide blade sheet, complex structure, the processing consumptive material is many, shortcomings such as cost height, after the guide vane after the impact briquetting and shell and inner casing are welded together, shell and inner casing are linked together with outer tube and water guide cone respectively and form whole stator parts, these stator parts have effective reduction flow stream velocity, eliminate the liquid in rotation component, speed can be converted to the pressure energy, with effects such as the liquid conductance go out, have and make simply, cost is low, hydraulic loss is little, the characteristics that efficient is high.
