Varible Speed Pump Control

Varible Speed Pump Control

Varible Speed Pump Control

(OP)
Can you help me to find information releated with control scheme for variable speed pump.
We are desiging a water pump injection system and we need information about this issue.
Pressure of system is 2400 psig with 4 pumps of 20 KBWPD each.  

RE: Varible Speed Pump Control

Have you done a google search already?

I am not an expert on this matter, but I would say first of all that with a VSD pump there is obviously no control valve. Depending what parameter you want to control, like level, flow or pressure, I would imagine that you have a measuring sensor, like a flowmeter, level meter, that goes to the pump driver to manipulate the driver speed.

Or a variable frequency controller?

What is a KBWPD  ???

   

RE: Varible Speed Pump Control

thousand barrels of water per day??

Nowadays my learned electrical friends say that a VSD is actually a variable voltage, variable frequency drive.

Is this homework?

There is no information at all on what you are trying to do. Injecting into the ground, injecting water in to a process, are you trying to maintain a constant flow, or a variable flow, or a constant pressure? what type of pump is it?

But you need a measured variable and then you modify the pump speed. You may need to start or stop pumps depending on the system and pump parameters.

RE: Varible Speed Pump Control

Hi,

For info. there is a section untitled:"control scheme for VSD pumps" in the september 2009 issue of Hydrocarbon Processing magazine: "Applying pumps with variable speed drivers".
