In this case, the water starts from a source higher than the pump. (This is important.) As this input water moves down from the source, it gains velocity and exits the drain valve. However, due to this movement of water, check valve A closes and water stops flowing.But the water is going to the closed valve, so it is redirected Up Passing through the other check valve B, the air layer is compressed. When the air is compressed, water stops flowing and valve B closes. When that valve closes, the compressed air acts like a spring to push the trapped water up the output pipe. Then the whole process starts all over again.
This is rather complicated. Adjusting the values to work correctly can be tricky. So I’m not going to build a ram pump, but if you want to try Here’s a great video showing what really works. (Good luck.)
In the meantime, let me point out an important aspect of this pump. First, the pump is lower than the water source, but the output is higher than the water source. It may seem strange, but it is. Second, every time water is pumped to a higher level, water is discharged from the pump. This is wastewater.
OK, back to TikTok videosCould it be the ram pump? Note that he needs 3 levels for this kind of pump. The output is at the highest level, the water source is in the middle, and finally the pump is below it. If you don’t have all three of these levels, you don’t have a ram pump.
In the drawing above, based on that video, the person draws water from a river that looks like a source.This can’t be a ram pump because the water doesn’t come straight out of the river. low level than the source. In this case, the source, not the pump, is the bottom layer of the system.
Another concern is drainage. A true ram pump should squirt excess water from the lower level. Without it, there would be no ram pump. There is no visible wastewater in the video.
So how does it work? who knows. Maybe it’s just an illusion. Maybe there’s an electric pump that’s submerged in the river and hooked up to a pipe.
A bigger question is whether the ram pump produces free energy. It sure looks like it because you’re moving the water to a higher place. It increases its gravitational potential energy instead of moving it down and decreasing its potential.
But in reality it is not. Let’s say you have a working ram pump. Suppose we start with 20 kilograms of water at the source. There is a pipe one meter down to the pump. After that, a portion of water (let’s say 10 kilograms) is pumped by him to a height of 1 meter. over it original source To increase with gravitational potential energy. This means that only 10 kg of water was discharged as waste at the pump level. Descent with gravitational potential. Overall, if 10 kg goes down 1 meter and 10 kg goes up 1 meter, the net change in energy is … zero. The pump “pays” for higher energy water in its output by forcing it to flow to a lower point.
Of course, in this example the pump is 100% efficient, but that never happens. Energy is lost in the released water and in the friction between the water and the pipe.
And this brings us to the final problem. Even with a highly efficient generator powered by falling water from a ram pump, not yet does not give you free energy. Some of the water must be drained at the bottom end, so the water source will eventually dry up.That means you have to use energy to lift more water to add to the sauce. Oh my god! Now the free energy scheme is lost.
Ultimately, both siphon and ram pumps move water without external energy input. more More energy than you started with. However, you may get water where you need it. And that’s the point of the pump.
