    Residual oil pump wear-resistant materials processing
　　
　　 Residue pump is the most wear-resistant parts material is the use of high-chromium cast iron, is currently one of the best performance wear-resistant materials. Slurry pump to deal with most of the media are abrasive, high concentration of slurry, so the slurry pump itself manufacturing materials, wear resistance and corrosion resistance requirements.
　　
Residual oil pump wear-resistant materials processing tools, as the technology advances in recent years have a certain breakthrough, that is, ceramic products emerging ceramic tool. Ceramic cutting tools are characterized by high strength, high hardness, good wear resistance, good chemical stability and low coefficient of friction, in the processing of similar slurry pump wear-resistant materials have greater advantages in the field.
　　
Residue pump manufacturers or supporting parts processing enterprises, are required to deal with high-chromium cast iron and other wear-resistant materials, the general use of mechanical processing tools are alloy cutting tools, such processing complex process, high cost and low efficiency, it can be said that high-chromium The difficult machining of cast iron has been a dilemma for troubled slurry pump producers.
　　
Residual oil pump manufacturers and ancillary components processing enterprises are also beginning to gradually promote and use of ceramic tools, according to the use of the situation, the ceramic tool can indeed solve the high-chromium cast iron machining problems brought about. At the same time, the use of ceramic cutting tools can also effectively reduce the production cost of the slurry pump, greatly increase the production efficiency and bring higher economic benefits to the enterprise.
　　
Residual pump in a wide range of industries to promote the use of, in the industry show good value. Residual oil pump is mainly used in mining, metallurgy, coal, electricity and other projects of mining, dredging, conveying tailings, slime, iron and other work.
　　
Cavitation pump residue cavitation causes
　　
The pressure of the residue pump fluid drops from the inlet of the pump to the inlet of the impeller, and the pressure of the liquid near the blade is the lowest. Due to the local part of the overcurrent part, the absolute pressure of the pumping liquid drops to the vapor pressure under the current temperature , The liquid is vaporized there and there may be overflow of the solution in the liquid to form many bubbles which flow forwards with the liquid and the pressure of the liquid outside is higher than that of the bubble Of the vapor pressure of the bubble will be dramatically reduced to the formation of cracks and cracks in the bubble shrinkage rupture at the same time, will have a great impact pressure, its value up to hundreds of atmospheres, the formation of water hammer, continuous blow metal surface, metal surface due to Impact and fatigue spalling. The occurrence of this phenomenon makes the overcurrent component corroded and destroyed, and the above-mentioned bubbles and bubbles are sharply reduced and the destruction of the overcurrent component ruptured is the reason of the cavitation during the operation of the residue pump.
　　
Oil pump pump running for a long time under the corrosion of the pump overcurrent part of the corrosion damage, which is due to the condensation of the metal surface is a strong impact on the metal surface pitting, serious, leading to loose metal particles and flaking, showing honeycomb Shaped, and even cause perforation, cavitation in addition to the destruction of mechanical force is also accompanied by electrolytic chemical corrosion and other complex forces, practice has proved that cure cavitation must prevent the operation of the pump flow channel bubbles.
