Vacuum cleaner design guidelines 2

[waIkman]

Hello,

I am looking for some guidelines regarding the engineering of a vacuum cleaner.
I need to do a rough sizing of a system that ressembles a vacuum cleaner and I have some hurdles which i don't really have great answers for, mainly:
-What vacuum is needed for X sized particles
-The losses of the pipes & filter
-The required power for said vacuum & airflow

I don't even know if it's the best subforum to ask this.

If anyone has a recommended book or website / tutorial, I thank you very much.

Have a nice day.

I'd Google "Pneumatic Conveying"

I would just buy one and take it apart....

You can't just google every answer to an engineering question, or get all your answers on a forum. Get in touch with some professionals. Find manufacturers that make products similar to what you need. (That's what Google is really good for.) There are many of them. And many of them will make "specials". Then you know that the design is done by experienced professionals. Some of them might actually have a current product that with just a few modifications or accessories can do your job. But the most valuable thing they have is a staff of application engineers whose only job in life is to help you be successful in the application of their product. I've been at this for a long time and I can tell you that the assistance of those application engineers is invaluable! Pick up the phone and talk to a live person.

You may find the Google it answer to be flippant but sometimes having a new search term can open up a new world of information. I'm sure OP has Googled "vacuum design" and got nowhere meanwhile "pneumatic conveying" may not be an obvious search term but is going to bring up a lot of specific and relevant information.

The "vacuum" is the wrong question. It's what is the velocity required. Then is it going vertically upwards or on an angle?
Filters will have a clean and dirty DP -Key question is what level of filtration do you want to achieve ( usually x% at y microns are trapped).

Unless you've got hundreds of metres, pipe loss is probably negligible. Filters and any restrictions / nozzles will swamp pipe loss.

Power also needs efficiency of the fan / blower.

Vaccum I would guess to be about 2.5 to 3m wc. Anything more and you're into more serious vacuum pumps / liquid ring etc.

is this for a domestic or an industrial (clean room ?) application ?

Is this a student post ??

Hello everyone,

Thank you for the help, and indeed "Pneumatic Conveying" has yelded some nice info, most notably the "Pneumatic Conveying Design Guide" from David Mills, which is filled with precious info.

This "project" is not very serious at the moment and is linked to another application in my company, I just wanted to have a rough idea of the size of such a system, and what would be the important parameters to consider, as well as how the system is roughly designed (position of the fan, filters, etc...).

Once we have a better idea of the viability of this idea, we will contact skilled engineers for this task

Thank you everyone !
