Can we run a compressor water pump driven by diesel engine to fetch water from bore wells?

Question

I started a orchard farm, waiting for electric supply. Till the time I want to pump water from a300 feet bore well to grow life fencing plants, water level is in 70 feet. so want to use a compressor pump as there is no electricity how can I use diesel engine to drive the compressor instead of eclectic motor.

Answer 1

1 with both engine and compressor bolted to the same bed connect the compressor shaft  to the diesel engine drive either by direct coupling or ofset a belt drive between the two. Suggest the rpm ratios are the same.

2 put your supply  pipe to the farm down about 100 feet into the well, or longer if you can.

3 insert the air supply pipe from the compressor some 5 feet down the bore

3. seal around the pipes and the bore hole, expander tube like a  bike or car tyre wraped around and inflated hard.

4 If it blows out put some concrete on it to hold it down after doing 3 again

5 start your compressor / diesel and raise around 100psi and water should flow into your garden

6 as the water level drops in the bore raise the air pressure.

Answer 2

you could certainly put a generator on the diesel, ......

you'd have to be way more specific about what you're trying to do to get a useful answer.

you can't draw water up 70'

you have to push it.

you can only draw 30' or less.

Answer 3

What everyone is trying to say is that you're going to need a submersible pump, one that will hang on the end of the pipe going down into the well.  The pump can be driven by an electric motor or by means of a driveshaft from the engine to a gear box to change the rotational direction 90 degrees.

You need to talk to someone who knows what they're doing when it comes to designing irrigation systems and sizing pumps.  Pumps have different pumping curves, which will give a person the amount of water it can move at so much head.  In your case, you're going to have a minimum of 70 feet of head just getting the water out of the well.  Additional head results from the friction of water flowing through the pipe.  The diameter of the, it's length and the amount of flow determines the additional head.  You can convert head into pounds per square inch of pressure by dividingit by 2.31.  The pump is going to have to work against 30 psi just getting the water to the top of the well plus additional head in the pipe..  

If you're in the US, try your local University Extension, Natural Resources Conservation Service or Soil & Water Conservation District.  The last two will be listed under governmnent and USDA.  Pump supplier can provide pump info and pipe resistance, but you need to figure out how much flow you need before the pump man can recommend a pump.

Answer 4

yes a compressor can force water to the top of a well. You put a device on the bottom in the water and force air down and brings water up. Check a rural water well supply

Answer 5

New Mexico Farmers use irrigation pumps like that. They are auto engines running natural gas to turn a pump. You should have no problem. Just do as someone said and make sure it is turning the pump in the right direction.

Answer 6

If the compressor pump is a rotating type, there should be only minor problems having a diesel to drive it. Be sure the diesel drives the compressor in the correct rotation, the speed should be constant.  If it's an indirect drive, the speed of the diesel vs the speed of the pump can be changed by using different size drive and slave pulleys, or link drives.
