Week #11: Pneumatic & Hydraulic Components & Cavitation

Post by rjagodowski »

This week we'll revisit a few of the links presented back in the recent weeks we might have skipped over due to time constraints.


Then we'll discuss hydraulic systems, pumps & valves and the topic of Cavitation in Hydraulic systems.

The Hydraulic System (has sound).

Hydraulic Pumps from wisc-online.com.

Hydraulic Directional Control Valves

Hydraulic System Pressure



The content below is presented in this week, but most likely will be covered within the next few weeks, depending upon our progress in course content.

Aeration vs. Cavitation in Hydraulic Systems from FluidPowerWorld.com .

Hydraulic Pump Cavitation - What is it & How can you prevent it.

Here's a video on Cavitation in Hydraulic Pumps from Koldwater Software (<5 min).

All About Hydraulic Cavitation (12 min)

We didn't view This Video in the Zoom Session for today, it's at a level a bit higher than we present. BUT...it does have some good effects. They are showing cavitation with water. BUT...if you start at about the 5:30 mark, they show the audible sound of the cavitation, but a bit later they show slow motion creation and implosion of cavitation bubbles, which is pretty neat. Continue watching to see the formation of the micro-jet which is the destructive pressure of the collapse. At 8:30 in the video they show actual pump impellers which have been exposed to cavitation, to show how the damage occurs.

This is a great video on Hydraulic Pump Life & Cavitation but is rather long(1hr 02min). A good watch when either stuck inside during a quarantine or for a cold winter night by the fire!
