Abstract
The invention provides a hard alloy amphibious sand pump capable of being idled and connected in series. The sand pump has the following advantage that the defects of the current sand pumps can be overcome by adopting the method of welding wrapper plates made of high-hardness alloying metal materials which are more wear-resistant and more resistant to sand impact than the original manufacturing metal materials to prolong the service lives.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running amphibious husky pump 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.At present, not yet retrieve and adopt two kinds of different hardness materials mutually to cover the amphibious husky pump of welding, therefore, the pump housing that common metal is made and the damageable zone of impeller are very fast in the sand discharge wearing and tearing, even also can be impacted pit by the grains of sand, and husky pump is scrapped too early.Someone once attempted adopting single high hardness alloy to make husky pump, but because high hardness alloy is relatively very crisp, was difficult for processing, easily fracture and can't realizing.These current difficult problems fail to solve all the time.
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 husky pump of can connecting, adopt welding more wear-resisting than original manufactured materials, the way of the covering version of the high hardness alloy metallic material of desertification grain impact increases the service life more, to overcome current shortcoming and defect.
The cemented carbide idle running of the present invention technological scheme that amphibious husky pump adopts of can connecting is: there is the compound overlay of abrasion resistance alloy metallic material and original metallic material at the position that pit appears in grains of sand high speed impact of being subject to of the pump housing and impeller.This overlay can be that the surface that is gone out water slug by impeller of guide plate in the pump housing is with overlay in the pump housing of wear resistant alloy material welding.Overlay can be the rear overlay with the wear resistant alloy material welding of the internal surface of back shroud of impeller, and its quantity is identical with the blade number, and between two blades.Overlay can be the blade overlay that the front side of vane of impeller welds with wear resistant alloy material.Overlay can also be the interior annular plate of circular groove that is set in the back shroud of impeller internal surface, is the zone that grains of sand high-speed punching hits pit between its internal diameter and the external diameter, and the back shroud internal surface after annular plate is inlayed is level and smooth.
More than the various wear resistant alloy materials that cover version to have a kind of coverings at least edition be cemented carbide.
Can the connect advantage of amphibious husky pump of cemented carbide idle running of the present invention is to adopt welding more wear-resisting than original manufacturing metallic material, the way of the covering version of the high hardness alloy metallic material of desertification grain impact increases the service life more, can overcome the shortcoming and defect of current husky pump.

Embodiment
Below in conjunction with accompanying drawing the cemented carbide idle running of the present invention amphibious husky pump of can connecting is further described.
Fig. 1 figure is cemented carbide idle running of the present invention amphibious husky pump the first embodiment that can connect.Fig. 1 is to Fig. 5, is the schematic representation that position that pit appears in grains of sand high speed impact increases the compound overlay of bi-material that abrasion resistance alloy metallic material and original Metal Material Welding are arranged that is subject to of the pump housing and impeller.This overlay can be among Fig. 5 the guide plate in the body of the pump housing 37 by the surface of the water outlet high speed impact of impeller 38 with overlay 36 in the pump housing of wear resistant alloy material welding, the guide plate of its periphery and original pump housing internal surface welds.
Overlay can be Fig. 1 and Fig. 2 back shroud of impeller 30 internal surface with the shape of the rear overlay 31. rear overlays 31 of wear resistant alloy material welding such as the oblique square grid among Fig. 2, the quantity of rear overlay 31 is identical with the blade number, rear overlay is namely arranged between all blades and the blade, and between two blades, weld, also to weld respectively at suction port one end and discharge opening one end of impeller.
Overlay can be the blade overlay 32 that the front side of vane of the impeller of Fig. 2 and Fig. 4 welds with wear resistant alloy material, and blade overlay 32 and front shroud welding also will weld with back shroud, also will weld with former vaned suction side, the end that spues.
Overlay can also be the interior annular plate 33 of the circular groove that is set in the back shroud of impeller internal surface among Fig. 3 and Fig. 4, be the zone that grains of sand high-speed punching hits pit between the internal diameter of annular plate 33 and the external diameter, the internal surface after the welding of the back shroud after annular plate 33 is inlayed is preferably level and smooth.
More than the various wear resistant alloy materials that cover version to have a kind of coverings at least edition be cemented carbide.
