Increasing RPM's to gain flow
Increasing RPM's to gain flow
(OP)
I understand that increasing the rpms will increase flow but how to know how many rpm's i can increase to before problems arise? My current motor is 10hp rated at 1770 rpm. Verticle turbine pump, 6 stages.
thanks

Sometimes the system is the limiting factor, sometimes the pump design is the limiting factor, sometimes the motor...
We need more info.

RE: Increasing RPM's to gain flow
maximum stable flow for the pump
maximum RPM rating for the pump
maximum RPM rating for the motor
amount of flow where NPSHa < NPSHr
power of the motor vs RPM
intersection of system curve vs pump curve at varying RPM (keep it close to the BEP)
maximum pressure rating of system components
maximum inlet velocity of the pump
pump configuration (multiple turbines)
minimum submergence
One or more of these items will limit the max speed.

I'm looking at my pump curve and where i want to be, 600-800 is too far off. my head would be really low and cavitation could occur. I think I might need to consider a new impellar. any sugestions would help.

I post the images I want to show on www.eng-tips.com to an image hosting website called Image Shack. There are a number of free hosting sites on the net, but you can find Image Shack at, www.imageshack.us
Go to www.imageshack.com and find the instructions for uploading an image to their servers. It typically just amounts to browsing your computer for your diagram and clicking the ImageShack button to upload the diagram.
Once the diagram is transferred to Image Shack, their web page will return several examples showing a number of common ways to link your uploaded image to various classes of web sites. Find the example link that looks like this one,
[url=http://imageshack.us][img=http
Unfortunately that does NOT work on Eng-Tips as it is, so you have to edit that link.
You should edit your link by removing all the characters indicated by "^" in the following,
[url htp://imageshack.us]
^^^^^^^^^^^^^^^^^^^^^^^^^
[img=http
^ ^^^^^^
leave a space where the equal “=” sign is.
You should now have a link that looks something like this,
Copy and paste that link where you want your diagram to appear in your eng-tips posting.
After you have the link pasted into eng-tips and finished your question or comment, check your work for proper formatting by clicking the "Preview Post" button just below the text box.
If it looks good, click "Submit Post"
