Introduction of duplex stainless steel casting impeller:
Duplex stainless steel casting impeller has the characteristics of impact resistance, corrosion resistance and wear resistance. Duplex steel impeller can reduce the energy loss of fluid delivery and provide stable and long-lasting power for fluid delivery in production.
Advantages of duplex steel impeller:
1. Duplex steel impeller has both the toughness of austenitic and the high strength of ferrite, and has the ability to resist stress corrosion. It is suitable for conveying corrosive media such as chloride ions.
2. The duplex steel impeller is manufactured by sand casting process, which can withstand centrifugal force at high speeds and has strong deformation resistance.
3. Duplex steel impeller has high hardness, and when conveying media containing a small amount of solid particles, the wear rate is lower than that of ordinary stainless steel and the replacement cycle is longer.
Use of duplex steel impeller:
1. Seawater treatment industry: duplex steel impeller can be used in seawater circulation pumps in desalination plants and coastal power plants, which can withstand the corrosion of high chloride ions in seawater.
2. Chemical industry: casting impeller can transport corrosive media containing acids, alkalis and salts, so it can transport fluids in the production of chlor-alkali chemicals and fertilizers.
3. Paper industry: casting impeller can be used in pulp conveying and black liquid treatment, and can withstand corrosion and fiber wear.
4. Oil and gas extraction: casting impeller can be used in the collection and transportation systems of offshore oil fields and acidic oil and gas fields to transport sulfur-containing and chlorine-containing oil and gas media.
FAQ:
Q1: What special matters need to be paid attention to when installing Casting impeller?
When installing casting impeller, it is necessary to ensure that the lifting equipment has sufficient load-bearing capacity and does not collide with the blades. The gap between the pump housing and the pump shell needs to be adjusted strictly according to the design value. The gap is too large, which leads to a decrease in efficiency, and too small may cause friction.
Q2: During use, it was found that the blades of casting impeller have slight corrosion spots. What should I do?
You can first lightly grind the corroded area with fine sandpaper, wait for the oxide layer to be removed, and then apply a special passivator for duplex stainless steel to form a protective film. If the corrosion area exceeds 5% of the blade area, it is recommended to contact us to assess whether it needs to be repaired.
