borehole solar powered pump install

[greenhouseparos]

thought to post some pics of the installation of our water borehole solar powered pump.
the pump is a Lorentz PS1200 HR-03H powered by 4 suntech 190ad+ panels.

so far we have drilled a hole











and layed the footings for the array supports and well head cover. we are in a high wind area hence the solid lookin array bases.














thats the base layed now waiting for them to dry to fit the  array supports

[greenhouseparos]

Have no fitted the array supports pump controller and the panels. here are some photos. Now i just need some reasonable weather and the pump will be installed.
Does anyone have experiance of installing a pump in a very deep hole. The pump will sit at 150m down and with 20kg pump, 150m of 32mm plastic pipe, 150m of 4 core 6mm cable, 150m 2 core 1.5mm cable and 150m of safety rope it will start to get quite heavey.

here is the framing
   


and the pump controller




2 of the four panels






all ready for the pump.

Use a thinner pipe this isnt a 3-phase mains powered pump your only going to get a trickle out the end of the pipe. that pipe full of water will weigh a ton.  Heres the same thing at only 12m.

[greenhouseparos]

to late for that roger i already got the pipe. 
When we was drilling we found no usable amount of water at 80m so kept drilling. at 120m we found about 2-3cubic of water. the extra 30m acts as a tank. The actual water level is 30m below the surface, however with such a small producing well the pump could draw that level down. (as an estimate the driller and the geologist both quoted the hole to be producing between 3-4 cubic a day. Although a relatively small amount for such an expensive hole 3-4thousand liters of water a day is more than enough for my needs.)
Anyway all this has led me to placing the pump far down the well to avoid any draw down issues. The actual head of lift starts at 30m so i am hoping that if there is a need to get the pump out I will only be dealing with 30m of pipe with water in it. Heavey but not as heavey as 150m.   
Tommorow (if the weather is ok) we will install. I thought about erecting a scafold over the hole and have the pipe slide over some support (wood planks) and into the hole. Hopefully if we need to stop we just pull down on the pipe the other side of the supports and that should act as a brake. Hopefully!!!

Now i just need some reasonable weather

What counts as reasonable weather?

[rogeriko]

First of all remove the one-way valve on the top of the pump so when it stops running the pipe will empty out. also as you lift it up the pipe will empty out to make it lighter. Above the well you have to make a Balango, thats a wooden drum with the steel wire rolled around it and two handles on each end. this is the winch that you use to raise and lower the pump. Of course you cannot winch the pipe around the drum so lay this out straight along the field and it will go down with the steel wire. AS IT GOES DOWN every meter you can clip all the wires and pipe together  not beforehand.

Not a good picture but you get the idea.

Reasonable weather for working in Greece means cloudy and cold because all these warm sunny days are perfect for sitting at the now fairly empty beaches and drinking a couple of beers.

so the weather wasn't great but we went ahead with the install. as it turned out the weather was very important in the install process.
here is the pipe, cable, low water sensor cable and the saftey rope all laid out. about 160m long
     


here is the pump



and here is the set up for the out let. the steel plate will sit flat on top of the well casing and take all the weight of the pump pipe and cables and also act as a cover closing the hole.


 
and down it goes



everything went smothly until about 80m down. it got stuck. we pulled it out and found that the cables and saftey rope had all got bunched up. you have to leave a little slack when tieing them to the pipe because the pipe streches about 2%. we retied them with less slack and lowered it again. 80m and it got stuck again??? we pulled it back out again to check but everything seemed ok. so slowly we lowered again trying to feel if we meet an obstruction. 30m and we feel it hit the water. 70m and it started to need help going down. 80m and again it became very difficult to get it down. a little bit of head scrathing then the realization that we were trying to push a pipe full of air down into water. the pipe didnt fill with water because the pump wouldn't let any water in. switching the pump controller on (it was cloudy but just enough light to start the pump) and slowly the pipe started to go down the hole by it's self. we managed to get all of the pipe down the well and get the top plate into position without any more problems. then atanding back to wait for the water to come out the controller shut off the pump due to low light levels and then it started to rain. will have to check the correct running another day.

heres a couple of links to some video of the pump doing exactly what it says on the packet. the flashing light on the controller telss you what speed the pump is at 5 flashes for max speed.

Great install, there !!!
Glad to have people here in Greece like you and Roger, trying RE projects. I live in Athens, but have a hybrid install on Syros island connected to local Cyclades Wireless Network, waiting for some service tasks to be done.

been pumping for about 4weeks now and i am very pleased with the results.
even when the weather is overcast it is still produceing 4cubics a day.
just one problem. when the hole was drilled they used washing up liquid as a lubricant for the drill bit. so now the water has still got soap in it. every day it gets more diluted but stilll taking it's time. i guess if i had mains elec pump and not limited to output i could pump all the water out and get rid of the soap. but i don't so i wait. the trees don't seem to mind.

Well done indeed greenhouseparos.....
Looking very good in some hard terrain.

the geologist came and took a sample for the relevant testing of the water. seems like the soapy water has finally diluted it's self and flushed out. tastes good to me. just in time because the new bathroom will be ready for water this week.
