Hydrotaran. Pump that pumps water for irrigation without electricity and fuel

We are accustomed to the fact that in order to pump water we need a pump powered by electricity or a motor pump (on a gasoline engine). But it turns out that it is possible to lift or pump decent volumes of water without consuming energy. What is needed for this? A simple and ingenious device is a gidrotaran. As well as a constant drop in water level at the installation site of this pump.

With a high pressure of water (for example, in a mountain river), some models of hydrotrans are capable of lifting water up to 40-50 m. No, this is not a perpetual motion machine. This is just the lawful use of hydraulics. We look at the hydraulic ram device:

Diagram and description of the hydraulic ram. In short, this simple device works like this: water, when flowing at a height difference, creates a pressure in the pipe, closing one valve and opening another. When the discharge valve is opened and the air tank is filled, a decrease in pressure is created in the system, which opens the main (bump) valve with a short-term outflow of water. But this valve closes quickly and a water hammer appears. Because the liquid is not compressed - it opens the discharge valve, filling the pumping pipe. The cycle repeats itself.

This animation makes the working principle more clear. Those. we take the flow of water that comes out of the air container. It is much smaller than what is shown on the right in the diagram, but the water in it is under pulsating pressure, and is able to rise to a decent height. Hydrotaran is not a perpetual motion machine - this device only converts the kinetic energy of a water flow through a water hammer into another water flow.

The invention of the principle of operation of the hydraulic ram appeared at the end of the 18th century. from the Englishman D. Whitehust and the Frenchman Montgolfier. But they made devices based on empirical laws. Only N. Zhukovsky at the end of the 19th century. summed up the theoretical calculations for this process of water hammer.

In the west, this device is known as the ram-pump (ram pump). In the USSR, the development of gidrotaranov Rogozin G.V. Under his command in Kyrgyzstan many similar pumps were manufactured and installed in canals and mountain rivers to raise water for irrigation to fields:

And now some manufacturers continue to produce similar installations for land reclamation and water supply, based on the developments of the Soviet engineer Rogozin:

Project for pumping water from a stream in Kyzyl. See how high the water is pumped without using electricity. Using only the laws of hydraulics and the pressure drop in the flow.

On this principle, not so long ago, prototypes for generating electricity were created:

Why they didn't go into series is a big question. Indeed, in these modifications, it is no longer the height difference in the river bed that is used, but the pressure difference at the surface and at depth, if I understood correctly. This installation has a problem: self-oscillations can be attenuated due to the solubility of air in the water of the air container. But it can be solved.

Imagine the village is located by a large and deep lake. Such a unit is installed together, lowers to the bottom on the platform and supplies electricity to the house. Neither gas nor firewood is needed. Pay only for service. The golden age of independence from energy monopolies!

But these are all large installations that can pump thousands of liters per hour and pulsed liquid supply to rotate generators. For the private sector and their needs, a less productive device is sometimes sufficient. Such hydraulic rams have long been made by both kulibins and small firms. Here are designs made from common parts that can be purchased at any store:

A minimum of details. The main cost is pipes or hoses for delivering water to the site. I saw a video on youtube that one craftsman was able to lay a water supply system at a distance of 250 m from the stream. But his water flow was created only 2 l / min. How to collect in detail - there are a lot of videos on youtube.

So what is the idea and meaning of this article? Let's say someone has a summer cottage, but no well. And the site is located next to a stream or river with a sufficient height difference in their bed. You can collect this simple hydraulic ram and pump water for irrigation even from a small stream. It will be necessary to take water upstream and downstream by 10-15 m to supply it to the hydraulic ram. And he will already supply water to your tank or drip irrigation system. As you wish. And all this without electricity and electric pumps.

This technology is especially suitable for homes located near streams and rivers in mountainous areas. There, the difference in the channel is large and the water can be pumped over long distances and heights. Unfortunately, hydrotaran is not suitable for lakes and lowland rivers, where there is no height difference even by 0.5 m for hundreds of meters.
