Hydrosonic Pump Project

This is the experimental hydrosonic pump project i've been working on. This
is the second test run. The pump was built completely from scratch and
I machined all the parts. The motor is 5HP 3 phase 1725 RPM and the pulley
ratio setup spins the rotor at around 3795 RPM. The resulted heating
of the water is not bad considering the rotor is 6.4" diameter and higher
speeds were in theory needed to get any cavitation with this size rotor. This is the first build.

wHEN YOU ADD A FLOW OF WATER...THE HEAT DISAPATES RAPIDLY.

THIS WILL WORK IN A CLOSED LOOP BUT AS THE HEAT IS REMOVED(FAN -HEAT EXCHANGER) YOUR PUMP WILL NOT KEEP UP. THESE ONLY WORK WHEN REHEATING THE SAME WATER OVER AND OVER...THAT WILL RAISE THE TEMP..BUT AS SOON AS THE HEAT IS REMOVED...ITS INEFFICIENCY IS EVIDENT

Maybe, but keep in mind this was the first of testing this after assembly. The project is not finished and waiting for more testing. I had little info, no plans or drawings to go on. All I had was simply some pictures and a video I seen. I had to make an educated guess on rotor size, hole size & depth and all the dimensions for the entire project. I'm suprised of the results on the first build for what info I had to go on. I've found a few who have attempted the project and got nothing at all.

I have started to get parts to build one of these. I have an old pump for use now but how did you over come the fact of getting a seal to stop the water getting into the bearing. I have been told various ways but am picking your brains at the moment.

I was also told to get it to spin as fast as possible to increase the heat in the cavitation effect.

what clearance did you have between the rotor and the cylinder walls?

I used a set of mechanical seals. They are the ceramic & carbon facing type typical of what you would find in a water pump. I just ordered the size I needed from an industrial supply company and designed the bearing hubs to house both bearings and seals.

What's the point? Would it not be more efficient just to heat the water directly with an electric heating element?

[andrewsengineering]

It could have some special uses, but even if the project was pointless, with mechanical engineering you will learn something from projects like this wether it works or not, and what you learn can be applied to other things. Same goes for the machine work.

I built one- got steam coming out of it. I ran mine at 10000 rpm-BUT-I could only run a trickle through it and that trickle had to be heated and reheated. I worked with a person who was involved in the Friction heater of the 70's.They too got heat from their machines..but again more power was required on the input side than could be gained on the output side. You like me guessed on the set up. I may revisit this at some point but for now its hard to beat an electric element when heating water
