How the fitting clearance between the screw and the sleeve of a labyrinth screw pump (LSP) affects the pump performance and what law it follows are still unsolved problems for LSP design. So the fluid quasi-steady flow in the pump with different clearances is approximately modeled by the shear-stress transport k-ω model (SST k-ω model) in multiple reference frame (MRF) of .
Centrifugal pumps are widely used in various industries for transferring fluids from one place to another. One of the key performance indicators of a centrifugal pump is its head-flow curve. The head-flow curve provides valuable information about the pump's performance at different flow rates. In this article, we will delve into the details of the centrifugal pump head-flow curve, exploring its significance, characteristics, and implications for pump operation.
The first curve under pump performance characteristic is the head Vs. flow rate curve. It is also known as a pressure vs. quantity curve. To draw this curve head is plotted on Y-axis, and the flow is plotted on X-axis. You can see the sample HQ curve in the image here. Now let’s convert this curve to a word so that
