Abstract
The invention provides a hard alloy amphibious mine vertical pump capable of being idled and connected in series. The mine vertical pump is characterized in that a short bent plate correcting the water conservancy curve of a fluid channel is arranged on the curved surface formed after a ring-shaped guide plate is broken at an outlet fluid channel inlet of a pump body and bends toward the center; and the short bent plate correcting the water conservancy curve of the fluid channel can be welded on one side of the concave curved surface or the convex curved surface. The mine vertical pump has the following advantage that if the fluid channel curve of the mine vertical pump body welded with steel plates is not ideal, the ideal requirement can be met by only attaching one short bent plate.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running amphibious vertical pump for mine of can connecting, it is land and dual-purpose amphibious type water pump under water, is applicable to carry the sand-discharging submerged pump that contains solid abrasive particles in the liquid or land with vertical pump.
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, not yet retrieve technological scheme about the correction runner water conservancy curve of welding pump housing runner.
Summary of the invention
The objective of the invention is: for mining provides a kind of amphibian amphibious type vertical pump for mine upgrading products---the cemented carbide idle running amphibious vertical pump for mine of can connecting, the pump housing for welding, easy as the pump housing of casting, revise runner water conservancy curve and become very easy, finally obtain desirable runner waterpower curve.
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 the curved surface after the central direction bending has the short bent plate of revising runner water conservancy curve.The short bent plate of revising runner water conservancy curve can be welded on concave curved surface one side.The short bent plate of revising runner water conservancy curve also can be welded on convex surface one side.Guide plate is that between two dividing plates one section can be arc plate at suction casing.Guide plate is that between two dividing plates one section also can be dull and stereotyped at suction casing.
The advantage of amphibious vertical pump for mine is undesirable with the vertical pump for mine pump housing passage curve of Plate Welding if cemented carbide idle running of the present invention can be connected, and can reach desirable requirement as long as subsidize a short bent plate.
Description of drawings
Fig. 1 is can connect a kind of embodiment's of amphibious vertical pump for mine overall generalized section of cemented carbide idle running of the present invention.
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
The invention will be further described below in conjunction with accompanying drawing.
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 can connect a kind of embodiment's of amphibious vertical pump for mine overall generalized section of cemented carbide idle running of the present invention.Fig. 2 is first embodiment's sectional schematic diagram of the blade wheel chamber of Fig. 1.
Among Fig. 2, circular guide plate 91 disconnects at pump housing outlet passage entrance 130 places and the curved surface after the central direction bending has the short bent plate 132 of revising runner water conservancy curve.The short bent plate 132 of the correction runner water conservancy curve of the first embodiment among Fig. 2 is welded on concave curved surface one side.
Among Fig. 3, circular guide plate 91 disconnects at pump housing outlet passage entrance 130 places and the curved surface after the central direction bending has the short bent plate 133 of revising runner water conservancy curve.The short bent plate of the correction runner water conservancy curve of the second embodiment among Fig. 3 is welded on convex surface one side.
So, if undesirable with the vertical pump for mine pump housing passage curve of Plate Welding, can reach desirable requirement as long as subsidize a short bent plate.
Among Fig. 4, guide plate 91-1 is that between two dividing plates 23,24 one section is dull and stereotyped at suction casing.Certainly, guide plate is that between two dividing plates one section also can be arc plate at suction casing.At this moment guide plate 91 no longer has been circular, and upper one section one section short slab that is cut open except weight reduction, mainly is the inspection of convenient welding and weldquality.
