Problems solved by technology

Some people have tried to use a single high-hardness alloy to make a sand pump, but because the high-hardness alloy is relatively brittle, difficult to process, and easy to break, it cannot be realized
These current problems have not been resolved

Embodiment Construction

[0012] The following is a further description of the cemented carbide idling and series-connected amphibious sand pump of the present invention in conjunction with the accompanying drawings.

[0013] figure 1 The figure is the first embodiment of the cemented carbide sand pump that can be idling and can be connected in series for amphibious purposes. Figure 1 to Figure 5 , is a schematic diagram of a cover plate made of wear-resistant alloy metal material and original metal material welded to the parts of the pump body and impeller where pits appear due to the high-speed impact of sand particles. This overlay can be Figure 5 The surface of the deflector in the body of the pump body 37 that is impacted by the water outlet of the impeller 38 at a high speed is welded with a wear-resistant alloy material to cover the cover plate 36 in the pump body, and its periphery is welded with the deflector on the surface of the original pump body .

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 [0001] The invention relates to a cemented carbide sand pump that can be idling and can be connected in series for amphibious purposes, which is an amphibious water pump for both land and underwater use, and is suitable for a submersible sand pump or a land vertical pump for conveying liquid containing solid abrasive particles. . Background technique [0002] The existing technology is called "Vertical Pump for Mining", and it has three invention patents: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0. At present, no amphibious sand pump has been found that uses two materials with different hardness to cover and weld each other. Therefore, the vulnerable parts of the pump body and impeller made of ordinary metal wear quickly in sand discharge, and may even be impacted by sand particles. pits, causing the sand pump to fail prematurely. Someone once tried to use a single high-hardness alloy to make a sand pump, but because the high-hardness alloy is rel...
