Clarification: Cavitation bubbles are NOT air bubbles, they are bubbles of vaporized process liquid (eg steam if the liquid is water). Entrained air (ie air bubbles which are already present in, or are injected into, the process stream) can actually be helpful in very small amounts (less than 1%), because they mitigate the effects of the more troublesome cavitation bubbles. But larger amounts of entrained air (or any kind of gas) can negatively affect pump performance and reliability in a number of ways, including inefficiency, vibration and air pockets which cause dry-running of the seals.

As someone who has serviced and sold pumps for over a decade, I can safely say that not only did you get all the science and physics of pump design correct, it's also the most informative centrifugal pump video I've ever seen on KZfaq or any other platform. Well done!

I'm not even studying mechanical engineering... I've just found myself building a pump from scratch... Realized an axial pump isn't what was most suitable, and a centrifugal pump is... designing 3d printing jet drives designed to be used on a kayak is fun... Untill you need specifics on how a centrifugal pump is actually designed and why

@Maverickf22flyer 4 жыл бұрын

Speaking of the flow direction based on the centrifugal pump's blades curvature, yes, you should tell in which direction the pump will have it's best efficiency for moving your fluid, hence from the eye center towards the blades tips, but it doesn't mean it won't reverse the flow if you rotate the rotor in opposite direction, but cavitation may occur much sooner (at some lower rpm and outlet pressures).

Pumps 101. Awesome. I understand that changing the impeller by just a little controls volume and preassure immensely. Most trash pumps do high volumes with low pressures. Fire pumps do higher pressures with lower volumes. Dredge pumps for small gold dredges are somewhere in the middle. Pump design is tailored specifically for its specific use and hose size.
