Water pump without power

This is not a joke or a prank. The water pump we are talking about really does not require electricity, gasoline, or anything else. It does not draw energy from the ether and does not catch free energy. With all this, it is capable of raising a column of water several times higher than the initial pressure. No deception or trickery - ordinary physics and nothing more.
Of course, if you see such a pump for the first time, then like me you may think that this is nonsense... The same as the invention of a perpetual motion machine... But no, everything is much simpler and quite easily explained. This is a 100% working model of a water pump, repeated by more than one craftsman.

Making a water pump


So, first, I will tell you how the pump works, and then its operating principle and operation in real conditions.

Design with description


This is what he looks like. Everything is made from PVC pipes.

In this case, the design looks like a straight pipe with various valves and taps, with a branch in the center of the thicker diameter pipe.
The thickest part is a buffer or receiver for accumulating and stabilizing pressure. Inlet and outlet ball valves are installed on the left and right.
I will be looking at the pump from right to left. Since the right side is the entrance for water, and the left is the exit.
In general, we realized that water is supplied to the ball valve on the right. Next comes the tee. Tee, separates the flows. It flows up to the valve, which closes when there is sufficient pressure. And the direct flow is supplied to the valve, which opens when the desired pressure is reached.
Then, the tee goes again to the receiver and to the output. Oh, and a pressure gauge, but it may not be there, it’s not that important.

Details


All parts are laid out before assembly. I use PVC pipes, they are glued with glue, but polypropylene can also be used.

Assembly


I'm collecting. The second valve is in the middle and looks a little different. The difference between these two valves is that the brass valve will initially always be open, while the PVC valve will initially always be closed.

Let's add a pressure gauge to measure pressure during operation.

Pump tests


It's time to install and test the pump. I would like to make a reservation and say that the pump does not pump water, but rather increases its pressure. What I mean is that the pump needs an initial pressure to operate.
To do this, install a pump in a small stream. Let's connect a long pipe several meters long (this is a mandatory condition) and draw water from a small hill. As a result, water will flow to the pump itself.

We place the receiver vertically, the brass valve should be in the open air.

And the pump, clicking the valves, begins to supply water above the intake level. Much higher than the level of water intake at the beginning of the pipe.

Working principle of a water pump


All this seems truly amazing and incredible, but there is no secret here.Such water pumps are also called hydraulic shock pumps and they work like this:
When water is supplied, it immediately rushes into the open valve.
Working principle of a water pump

As soon as the water gains a slight run-up, this valve will close sharply. And since the column of water in the pipe has inertia, like any physical mass, a water hammer will occur, which will create excess pressure that can open the second valve. And the water will rush into the receiver, where it will compress the air.
Working principle of a water pump

As soon as the excess pressure is extinguished and becomes less than the outgoing one, the middle valve will close and the upper one will open. As a result, water will again flow through the top valve.

Then the cycle repeats.

Such pumps can create pressure 10 times higher than the initial one! And to confirm this, watch the video:

    My son did something weird here in the plastic assembly without looking at the drawing in the video announcement. The primary hydraulic shock pump will not work if assembled as in the photo. For the simple reason that it is nonsense.But the drawing on the video poster is a viable device that is countless years old.

      Dear Monk, be kind enough to speak in technical language and not in market language. Why won't the pump work? If it works from the energy of flowing water in a stream, then it is perpetum mobile as long as the stream flows.

    I also think that the circuit in the photo is not working. The outlet pipe must be installed as in the diagram in the video.

    The photo is definitely not a working diagram, why would water go into the receiver after the valve, if there is pressure in the receiver, but there is no pressure further down the pipe, the receiver simply will not fill, but in the video the diagram is correct

    The laws of physics have not been repealed. Learn materiel.

    For running water in the form of a spring, there has long been a pump using it (lifting to any(!) height)

    The only good thing about the design is that it is simple, but it requires constantly flowing clean water for the valves to work properly. This design does not apply to the Perpetum Mobile. Any water mill or hydraulic turbine can supply a small part of the water energy under higher pressure, if part of the water energy that it uses is supplied to a water pump or any other. In this case, the authors prefer to remain silent about the efficiency, without comparing it with other alternative options.

    1. Both circuits are working.
    2. It doesn’t have to be a stream. Enough water at higher elevations. It turns out that the water initially drops from the starting point to the pump, and then the pump raises it above this starting point.
    3.The pump consumes water. Some of the water remains at the lowest point where the pump is located.

    As a firecracker valve, you can use a regular check valve with the spring pulled out.

    What to do with water? which splashes out of the valve? Only suitable for installation in a stream. This is a great idea, hats off!
