Abstract
The present invention is that a kind of cemented carbide idle running can be connected amphibious vertical pump for mine.Circular guide plate disconnects in pump housing outlet passage ingress and curved surface after bending to central direction has the short bent plate revising runner water conservancy curve.The short bent plate revising runner water conservancy curve can be welded on concave curved surface side.The short bent plate revising runner water conservancy curve also can be welded on convex surface side.If undesirable with the vertical pump for mine pump housing passage curve of Plate Welding, as long as subsidize a short bent plate can reach desirable.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running can to connect amphibious vertical pump for mine, it is land and amphibious type water pump dual-purpose under water, is applicable to carry in liquid containing the vertical pump of the sand-discharging submerged pump of solid abrasive particles or land.
Background technique
Prior art, " vertical pump for mine " by name, it has three patent of invention: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0.For the pump housing of welding, easy unlike the pump housing of casting, revise runner water conservancy curve and seem very difficult.At present, the technological scheme of the correction runner water conservancy curve about welding pump housing runner is not yet retrieved.
Summary of the invention
The object of the invention is: for mining provides a kind of amphibian amphibious type vertical pump for mine upgrading products---cemented carbide idle running can be connected amphibious vertical pump for mine, for the pump housing of welding, easy as the pump housing of casting, revise runner water conservancy curve and become very easy, the runner waterpower curve that final acquisition is desirable.
The cemented carbide idle running of the present invention technological scheme that amphibious vertical pump for mine adopts of can connecting is: circular guide plate disconnects in pump housing outlet passage ingress and curved surface after bending to central direction has the short bent plate revising runner water conservancy curve.The short bent plate revising runner water conservancy curve can be welded on concave curved surface side.The short bent plate revising runner water conservancy curve also can be welded on convex surface side.Guide plate is between two dividing plates one section at suction casing can be arc plate.Guide plate is between two dividing plates one section at suction casing also can be dull and stereotyped.
If cemented carbide idle running of the present invention can be connected, the advantage of amphibious vertical pump for mine is undesirable with the vertical pump for mine pump housing passage curve of Plate Welding, as long as subsidize a short bent plate can reach desirable.
Accompanying drawing explanation
Fig. 1 is that cemented carbide idle running of the present invention can be connected the general profile schematic diagram of a kind of embodiment of amphibious vertical pump for mine.
Fig. 2 is first embodiment's sectional schematic diagram of the blade wheel chamber of Fig. 1.
Fig. 3 is second embodiment's sectional schematic diagram of the blade wheel chamber of Fig. 1.
Fig. 4 is embodiment's sectional schematic diagram of the suction chamber of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
For the pump housing of welding, easy unlike the pump housing of casting, revise runner water conservancy curve and seem very difficult.
Fig. 1 is that cemented carbide idle running of the present invention can be connected the general profile schematic diagram of a kind of embodiment of amphibious vertical pump for mine.Fig. 2 is first embodiment's sectional schematic diagram of the blade wheel chamber of Fig. 1.
In Fig. 2, circular guide plate 91 disconnects at pump housing outlet passage entrance 130 place and curved surface after bending to central direction has the short bent plate 132 revising runner water conservancy curve.The short bent plate 132 of the correction runner water conservancy curve of the first embodiment in Fig. 2 is welded on concave curved surface side.
In Fig. 3, circular guide plate 91 disconnects at pump housing outlet passage entrance 130 place and curved surface after bending to central direction has the short bent plate 133 revising runner water conservancy curve.The short bent plate of the correction runner water conservancy curve of the second embodiment in Fig. 3 is welded on convex surface side.
So, if undesirable with the vertical pump for mine pump housing passage curve of Plate Welding, as long as subsidize a short bent plate can reach desirable.
In Fig. 4, guide plate 91-1 is between two dividing plates 23,24 one section at suction casing is dull and stereotyped.Certainly, guide plate is between two dividing plates one section at suction casing also can be arc plate.At this moment guide plate 91 has been no longer circular, and on by the one section of one section of short slab cut open, except weight reduction, the mainly inspection of convenient welding and weldquality.
