Post-processing of large castings, large foundry processing manufacturers can use liquid sandblasting to clean the oxide scale and residue on the surface of the casting, which can not only remove impurities, but also play a role in polishing and improving the surface finish of the casting; Use grinding wheels, abrasive cloths, sandpaper and other abrasives to remove impurities such as burrs, protrusions and oxide scales on the surface of steel castings, so that the surface is smooth. In addition, methods such as mechanical, electrochemical and chemical polishing can further improve the gloss and corrosion resistance of castings.

In the world of drilling operations, particularly in oil and gas exploration, the mud pump plays a crucial role. A mud pump is a vital piece of equipment that circulates drilling fluid (commonly referred to as mud) from the surface to the drill bit and back up to the surface. This fluid serves multiple functions it cools and lubricates the drill bit, removes cuttings from the wellbore, and maintains the necessary pressure to prevent the influx of formations fluids. Therefore, accurately calculating the performance of a mud pump is essential for efficiency and safety in drilling operations.
