(2) If the shaft is different from the stuffing box axis, it is mainly due to processing errors and incorrect installation. Then pay attention to check whether the installation is correct after installation. If the sealing water ring is badly worn, a new water ring needs to be replaced. If the sealing water pipe is blocked, the sealing water cannot enter the middle of the packing, resulting in rapid wear of the packing, resulting in material leakage, you should dredge the blocked water pipe and keep the sealing water clean.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.

Once the materials are chosen, the manufacturing process kicks off with precise molding and machining operations. Advanced machinery ensures that every component meets stringent quality standards. The creation of the impeller is particularly critical, as it plays a vital role in fluid dynamics within the pump. Factories employ computer-aided design (CAD) technology to develop and test various impeller designs, optimizing them for maximum efficiency.
