Centrifugal pump is a kind of pump equipment. It is one of the pump accessories, one guide vane, and one of the main accessories of centrifugal pump. In the past, the guide vanes were mostly produced by sand casting. The internal quality of the castings was unstable, and it was easy to produce common casting defects such as shrinkage, shrinkage, pores, inclusions and cracks.
With the advancement and improvement of the technology, in the process of manufacturing the guide vanes of the pump parts, the rough finished products are mainly cast by forging, and then finished, to obtain the final product.
In this way, the overall performance of the vane of the pump fitting can be improved during actual machining. In view of the actual application, in the pump work, the guide vanes are used in the backflow of the hydraulic machine, such as the movable guide vanes of the turbine, the fixed guide vanes, and the guide vanes in the water pump. Their role is to produce a good amount.
As one of the key components of the centrifugal pump, the guide vanes of the pump fittings are commonly used in the manufacturing process: 20SiMn, 0Cr13Ni4Mo, 0Cr13Ni5Mo, 0Cr16Ni5Mo, and the like. As for which material to use, it is determined by the actual requirements of the user.https://www.dmgcastings.com/
