Background
When the submersible pump pumps water containing silt or other impurities, the silt and the impurities can seriously abrade the impeller blades. When the water pump works in a large-flow low-lift state, cavitation can be generated, and blades of a water pump impeller are damaged in an accelerated mode. Silt and cavitation can cause the water pump to lose efficacy quickly. If the abrasion and damage of silt and cavitation to the impeller blade can be avoided or reduced, the service life of the impeller can be prolonged, and the faults of the water pump are greatly reduced.
The existing solution is to improve the sand and cavitation resistance by selecting high-performance materials to make the impeller or coating protective materials on the surface of the blade.
If high-performance materials such as precipitation hardening stainless steel, wear-resistant copper alloy, alloy steel and the like are selected, although the cavitation erosion resistance of the impeller can be improved to a certain degree, the impeller has the following defects: the sand resistance is improved to a limited extent, the impeller processing difficulty is increased, the material is expensive, and the cost is high.
If the impeller cavitation resistance is improved by coating the protective material on the surface of the blade, the scheme has the following defects: 1. the coating suitable for the impeller is not sand-resistant; 2. when coating, the surface of the blade needs to be cleaned, and the surface is cleaned, activated, dried, sprayed, heated and cured. The process is complex and the energy consumption is large; 3. special pretreatment, coating and coating curing and baking equipment is also needed, so that the equipment cost is increased, and a large amount of space is also needed; 4. the price of the coating material is not very high, and the cost is high; 5. the quality of the coating is not easy to guarantee and the coating is easy to peel off.
