Centrifugal pumps are one of the most common types used in industry. It’s a device that pumps mud for solids control equipment. Figure 1 shows a generic, single stage centrifugal pump and Figure 2 illustrates a multistage centrifugal pump.Continue reading “Centrifugal PUMPs”
Driven by motor, the pump body and inlet line are filled with liquid before starting the pump. With high-speed rotation, the impeller drives the liquid between the vanes to rotate together. Due to the effect of centrifugal force, the liquid is thrown to the outer edge of impeller from the impeller center with kinetic energy increased. After the liquid entering the pump shell, as the flow channel in the volute type pump shell is gradually enlarged, the liquid velocity is decreased gradually, which makes part of the kinetic energy transform into static energy, therefore the liquid with high pressure is discharged along the outlet. At the same time, the impeller center forms a certain vacuum for th at the liquid is thrown out. The pressure on liquid level is higher than that of impeller center, so the liquid in suction pipe will flow into the pump under the action of pressure difference. With the constant rotation of impeller, the liquid is sucked and extruded continuously.
Ever since 2000 BC when the Egyptians invented the shadoof, a pump used to draw water from wells, the pump has been a key component of everyday life. Here are several types of pumps invented since then, along with some of their most common applications. The wide variety of pumps for today made it impossible for us to include them all.
This video shows how these solids control equipment (shale shaker, desander, desilter, mud cleaner, centrifuge and pumps) works.
