Abstract
The utility model relates to field of mechanical technique, about a kind of runner envelope on motor, especially about a kind of welding type runner envelope.Comprise the cylinder-shaped body that one end open is greater than the other end outlet, it is characterized in that, described body is bolted fixing halfbody by two and forms; Halfbody inner top side is inclined-plane, and is 80 °-85 ° with the angle of level, and inside halfbody, low side is vertical plane.The utility model has the advantage of: opening is greater than the other end outlet, can realize the acceleration during output of current, increases the kinetic energy of water, thus promotes the impeller quick rotation in runner envelope, improves generating efficiency.
Description
Technical field
The utility model relates to field of mechanical technique, about a kind of runner envelope on motor, especially about a kind of welding type runner envelope.
Background technique
Runner envelope connects base ring in axial flow, inclined flow turbine and draft tube forms water passage, and forms appropriate gap with runner bucket outer rim.Although existing runner envelope not only can play ensure runner safe handling therein, it still also exists some shortcomings part, and such as, existing runner envelope volume ratio is comparatively large, heavier, and transport inconvenience very, adds cost of transportation simultaneously; In the process of transporting and use, be inconvenient to put forth effort, cause local pressure uneven, easily damage runner envelope, occur that working life is short, the phenomenons such as user cost is high.In addition, after runner envelope is imbedded, owing to being difficult to ensure surperficial uniform force, the time has been grown easy appearance and has damaged.
Model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of simple for structure, surperficial uniform force, the welding type runner envelope of long service life.
For achieving the above object, the utility model have employed following technical proposal: a kind of welding type runner envelope, and comprise the cylinder-shaped body that one end open is greater than the other end outlet, it is characterized in that, described body is bolted fixing halfbody by two and forms; Halfbody inner top side is inclined-plane, and is 80 °-85 ° with the angle of level, and what lower end, inclined-plane connected is sphere, and inside halfbody, low side is vertical plane.
In above-mentioned a kind of welding type runner envelope, described body outer surface is provided with through stiffening rib and latitude stiffening rib, and the described jointing place through stiffening rib and latitude stiffening rib is connected together by welding.
In above-mentioned a kind of welding type runner envelope, the joint between described halfbody is provided with O type rubber bar.
Compared with prior art, the utility model has the advantage of: opening is greater than the other end outlet, can realize the acceleration during output of current, increases the kinetic energy of water, thus promotes the impeller quick rotation in runner envelope, improves generating efficiency.
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. 1 is the structural representation of halfbody in model utility.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of welding type runner envelope, comprise the cylinder-shaped body 1 that one end open is greater than the other end outlet, current flow into from opening, flow out, in this process from outlet, opening can expand current influx more greatly, go out young, the quick flowing of flow can be accelerated, thus the impeller quick rotation between promoting.Described body outer surface is provided with through stiffening rib 2 and latitude stiffening rib 3, and the described jointing place through stiffening rib and latitude stiffening rib is connected together by welding.By the rigidity of the whole outer surface of body can be made more even through stiffening rib and latitude stiffening rib, rigidity is more strengthened.Described body is bolted fixing halfbody by two and forms 4, and the joint between halfbody is provided with O type rubber bar 5, and rubber strip, when connecting, can play the effect of sealing, avoid phenomenons such as leaking.Halfbody both sides are provided with contiguous block 6, and contiguous block is provided with several attachment holes 7, and bolt and attachment hole coordinate and can realize two halfbodies and connect into a complete runner envelope.Halfbody inner top side is inclined-plane, and is 80 °-85 ° with the angle of level, and what lower end, inclined-plane connected is sphere, and inside halfbody, low side is vertical plane.Such as, when angle is 85 °, the water yield that opening flows into can be larger, and when angle is 80 °, the water yield that opening flows into can be slightly little, specifically determines according to actual conditions.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
