How does a screw pump work in solids control system?

Screw pump is having the simplest working on the entire pumps. How does a screw pump work insolids control system?

Let’s start with fluid coming at inlet at the bottom most part of this pump.

Now since driver screw is rotating and other two drive screws are also rotating but in different directions, they tend to build up the suction pressure at the bottom part. This suction pressure makes the fluid to move upward. Fluid passes through the small clearance between these screws and also the centrifugal force is experienced by this fluid. Both of these factors contribute towards providing the force which in turn results in the development of pressure in the fluid.

Screw Pump

A screw pump is a positive displacement pump that use one or several screws to move fluids or solids along the screw(s) axis. In its simplest form (the Archimedes’ screw pump), a single screw rotates in a cylindrical cavity, thereby moving the material along the screw’s spindle. This ancient construction is still used in many low-tech applications, such as irrigation systems and in agricultural machinery for transporting grain and other solids.

Development of the screw pump has led to a variety of multi-axis technologies where carefully crafted screws rotate in opposite directions or remains stationary within a cavity. The cavity can be profiled, thereby creating cavities where the pumped material is “trapped”.

In offshore and marine installations, a three spindle screw pump is often used to pump high pressure viscous fluids. Three screws drive the pumped liquid forth in a closed chamber. As the screws rotate in opposite directions, the pumped liquid moves along the screws spindles.

Three-Spindle screw pumps are used for transport of viscous fluids with lubricating properties. They are suited for a variety of applications such as fuel-injection, oil burners, boosting, hydraulics, fuel, lubrication, circulating, feed and so on.

Compared to centrifugal pumps, positive displacements (PD) pumps have several advantages. The pumped fluid is moving axially without turbulence which eliminates foaming that would otherwise occur in viscous fluids. They are also able to pump fluids of higher viscosity without losing flow rate. Also, changes in the pressure difference have little impact on PD pumps compared to centrifugal pumps.
