In this case, the water flows from a source higher than the pump. (This is vital.) As this input water moves downstream from the source, it picks up speed and exits through the drain valve. However, this moving water closes the check valve A, stopping the water from flowing out. But because the water flows into the closed valve, it’s diverted up downstream of the second non-return valve B and causes the air space to be compressed. When the air is compressed, the water stops flowing and valve B closes. When the valve closes, the compressed air acts as a spring to push the trapped water up the discharge pipe. Then the entire process starts all yet again.
It’s quite complicated; it’s hard to regulate the values to make the whole lot work properly. So I’m not going to construct a piston pump, but when you need to try, here’s a nice video showing one that actually works. (Good luck.)
In the meantime, let me indicate the important thing features of this pump. First, the pump is lower than the water source, however the efficiency is higher than the water source. It could appear strange, nevertheless it is what it’s. Secondly, each time water is pumped to a better level, some water is thrown out of the pump – that is sewage.
OK, back to the TikTok video. Could or not it’s the ram pump? Note that you simply need three tiers for one of these pump: The exit is at the highest, the water source is in the center, and at last the pump is at the underside. If you do not have all three of those levels, you do not have a plunger pump.
In the diagram I drew above, based on this video, an individual is pumping water out of a river that appears to be a source of water. So it might’t be a plunger pump because water cannot flow straight from the river. Remember that the pump have to be at temperature A lower level than the source. Again, the source, not the pump, is the bottom level of the system.
Another thing to look at out for is sewage. In an actual plunger pump, additional water should flow from the underside level. Without it you do not have a ram pump. And there is no sewage within the video.
So how can it work? Who knows. Maybe it’s just an illusion. Maybe there’s an electrical pump submerged within the river and connected to a pipe. I attempted to message the one who posted the video but got no response.
The larger query is, does a piston pump create free energy? It actually seems that way because you might be moving the water to a better place. This would increase its gravitational potential energy as an alternative of shifting it down and reducing its potential.
But that is probably not the case. Let’s imagine now we have a working piston pump. Suppose I start with 20 kilograms of water on the source. A 1 meter long pipe results in the pump. Then a number of the water (say 10 kilograms) is pumped to a height of 1 meter above original source in order that increases into gravitational potential energy. This signifies that only 10 kg of water was discharged as waste on the pump level – but because it flowed downwards, it had reduction in gravitational potential. Generally speaking, with 10 kg falling 1 meter and 10 kg rising 1 meter, the entire energy change is…zero. The pump “pays” for the higher-energy water on the outlet by passing the water to a lower point.
Of course, in this instance, the pump could be 100% efficient—and that never happens. Energy is lost within the discharged water and the friction between the water and the pipe.
And that brings us to the ultimate problem: even in the event you had an incredibly efficient generator powered by falling water from a plunger pump, Still wouldn’t provide you with free energy. Since a number of the water must be discharged on the lower end, the water source will eventually dry up. This would mean you’ve to make use of energy to rise up more water so as to add to the source. Oh no! Now you simply lost your free energy plan.
Ultimately, each a siphon pump and a reciprocating pump move water with none external energy input – but you aren’t getting more energy than at the start. However, you may get water where you wish it. That’s what the pump is all about.
