Working of Screw Pump

02/15/2016 1:05 AM

Hi pals,

I am very new to design of screw pump, currently working on Triple screw pumps, i need to understand working principle of screw pump and how the pressure is built to certain flow (Change in momentum behind it). Please share some documents or any design procedure to start this screw pump design (triple screw pump).

I have 2+yr exp in design centrifugal pump. In centrifugal pump centrifugal force imparts energy to fluid passing impeller radially and converted to pressure energy by volute cross section having with increase in area.

I do not have an idea of how pressure is built in screw pump and dint get much documents which explains the same in net. Any one who have good experience in designing of those it will be very helpful if you guide/share some documents which helps to start my learning.

Thanks in advance.

As in gear pumps the screw pump is a volumetric pump and pressure builds up according to circuit resistance.

Ask for training from the employer.

An interesting concept, design something you have no idea about the working principals.

Any jobs going in your company? There's lots of things I don't know about, I would be a positive asset to the design department.

Talking about 'Outside the Box thinking' is taking too literally.

Thanks guys.

The reply i saw was just a definition which i am already aware of that, All i need is guideline and procedure to design the screw pump.

Dude!!

Designing which you don know the working principle is what challenging one i would say and this is the way you learn different things in your life.:) I am well aware of design of centrifugal pumps so its my next step to move to screw pump. All i need is guidelines form experienced person and support.

IT will be helpful if i get some procedure notes or some guidelines

Thanks buddies:)

Hi Dude. And here is India being a super power, leading the way and you have no back up. Try the Universities in your area.

A good guideline below Dude:

Wow. Here is a company that has no procedures to design things and no basis upon which to train other than to direct people to an anonymous internet forum for guidance. What a way to run a railway!

<...Dude...> needs to find a better employer.

I doubt this is a company and it has more possibility of a lad educating himself from others and becoming an 'expert' in his local region with a grand idea and half cocked information to start his new business venture.

How many requests for standards, documents and design and back up info, come from Indian posters? They know how to run their railway on cost effective means. One cannot get much cheaper than 'free'.

It doesn't sound right...

Wouldn't it be better to ask the experts at your company.... it just seems your trying to get some keywords and techniques to impress in your group.

I call it parroting, this is usually done by salesmen who don't know what they're talking about and I'll call them out on it.

For starters:

https://en.wikipedia.org/wiki/Screw_pump

Should give you a general idea of operation.

Check out references listed after the article for more detailed info.

There are numerous Indian manufacturers of triple screw pumps. Perhaps it would be easier to simply purchase one to aid in your quest to design one.

That a wrong link; it gives a foreign-language overview of Wiki, nothing about screw pumps.
