The impellers of alkali melting pumps are often clogged with nickel powder; does anyone have any good solutions? The concentration is 98% and the temperature is 400
Thread Content
The equipment uses melt alkali pumps from Jiangsu Feiyue; the medium contains nickel powder, the temperature is 400 degrees, the concentration is 98%, and the operation cycle lasts for over a month.
What is the shape of the impeller? Open? Semi-open? Closed? Also, is it for continuous use or intermittent use? If it is used intermittently, it should be cleaned and maintained promptly after shutdown; if possible, it is recommended to pump clean liquid through it for a while during shutdown.
Check the flow rate, head, and specific gravity to see if the selection was incorrect Can a clogged pump burn out its shaft? Reduce the resistance at the outlet; try adding a spiral vane in the inlet pipe. Consider replacing it with a forced circulation pump or a mixed-flow pump.
May I ask the original poster whether the nickel powder must be conveyed together with the molten alkali? What is the function of nickel powder? Nickel has a specific gravity of 8.9; a large difference in specific gravity will certainly lead to centrifugal separation. I have been involved in nickel smelting for over 20 years.
