Quote:An Archimedes screw with a bevy of serfs to operate it. Duh.


Do I have to think of everything around here?

 

I'm really going to put my intellect to the test but I'm trying to design it to run on water pressure only. Screw the pump motor.

Now I'm no Engineer... wait, yes I am. Scratch that last part.

 

While I am no good Engineer, I'm pretty sure that the job of the pump is to make the pressure. And the motor is what the pump uses to make the pressure. I can double check on that if you want, but I'm pretty sure that's how that goes.

I've been waiting for the Engineer to show up! I'm injecting into my main flow line. The injector needs 15-20% positive pressure in order to run. The booster pump is what normally does that, with the inlet and the outlet are both post filter.

 

However my water filter hogs up like 5lbs of pressure, taking it from 20.5lbs pre-filter to 15.5lbs post-filter. So I would like to change to inlet to pre-filter location and just let the hydrology take care of things. The problem is finding a small auxiliary filter that doesn't take up much pressure but also has a small enough micron filter to keep the water clean and stay un-clogged for at least 12 hours.

 

Does that really layman explanation sound viable to you? It sounds to me like it will work but then again I basically dig ditches for a living.

Let me see if I have this right; take a look at the really bad diagram that I cooked up and tell me how wonderful it is.

 

<p style="margin-left:40px;">     Injection Line

<p style="margin-left:40px;">-------| filter |---------| booster pump |-------

<p style="margin-left:40px;">                                                                I

<p style="margin-left:40px;">                                                                I

<p style="margin-left:40px;">      Main Line                                           I <-- Tie in point for Injection Line to Main Line (Must be 15-20% - 20.5 psi - higher psi than Main Line).

<p style="margin-left:40px;">-------------------------------------------------------------

<p style="margin-left:40px;"> 

And you want the inlet to occur before the filter. Do you mean the booster pump inlet or the tie in point inlet?

 

If you want the filter to be after the booster pump, that means that you are going to risk fouling up your booster pump with all the stuff in the water that ain't water.

 

Let me know if this is right or wrong and we can go from there.

This is basically the setup. So the Booster is taking water post filter, creating positive pressure and re-injecting about 6 inches below via a Mazzei injector. What I'm trying to do is move the booster inlet from point 2 to point 1. It has more than a 15% differential so it should work unless I'm completely missing something. I just need to figure out how to keep the water clean for small periods at a time.

Well, you completely ignored my demand for compliments on my diagram, but that's okay. I'll let it slide just this once.

 

Are you going to move the booster outlet to a spot before the filter as well? If you do this, you may run the risk of 'blowing out' the filter due to the increased pressure going into the filter. Assuming that the booster will in fact increase pressure.

 

Just by looking at the design, it seems that the thing was drawn up the way it was because the filter makes such a drop in pressure, else why even bother? As I stated before, if you try and run a pump - centrifugal, I am assuming - without some kind of inlet filter or screen you are running the risk of fouling up the pump.

 

How often is the filter cleaned / flushed?

I meant the booster pump inlet but then without the pump. The injection line has a filter, obviously the mainline has one. The problem moving the inlet line pre main filter means I'm putting silt into the irrigation lines which will cause big problems. I don't have a lot of pressure to spare to keep the differential above 15% though to I'm looking for a small filter that will keep the water clean enough, not take more than 1lbs of pressure while allowing flow for 12-24 hours before having to be cleaned

You're diagram made me want to party like it was 1999!

 

No only the inlet will be moving, and then there will be no booster pump. Every line gets a filter and they are cleaned before every use.

Yeah, when I started farming no one told me there would be math involved.

1. That's gonna be your biggest hurdle. All of that silt is what is going to cause that filter to have such a big pressure drop and I really don't know how you would get around that.

 

2. Do you have an idea of the mesh size that you absolutely need to have on the filter? Maybe you can go to a bigger mesh size and still get the performance that you want.

 

 

Seems to me that they put that filter in because they knew that the pump needed to be protected, and that the filter was going to cause such a drop that they were going to need a pump to make up for it. Is setting up another filter in parallel with the one that already exists an option? That way, the system can operate while you clean the offline filter.

105 Microns. Nothing will be damaged by letting sand through per se, it just clogs up emitters of which there are roughly 15,000. That's a bit more than I like to change on the weekend 

 

The main line has a Spin-Clean filter which allows it to run for hundreds of hours between cleanings. The injector stuff just needs to stay clean for a day basically, so I can get away with smaller filters that rob less pressure. I hope.

Well, if you are settled on the no pump route, I think that filter size is your most logical solution spot. Good luck man.

All kidding aside, I'm not that guy. I was just simply trying to state that that engineer stuff is waaay over my head.

I think what I'm going to do is try to set it up to do both that way when my engineering skills fail me, I can still use it the old way. I found a pump that they tried to charge me $1400 for, for $380. Suckers.

 

I'll let you know how it turns out though!
