What is the maximum height to which a ram pump can carry water, as in this case we have a high efficiency pump of one and a half inches and we have a load of two meters, why do I say Two meters because the only thing we have to count is the vertical height the vertical component in this case we have this inclined pipe six meters long that is to say that the pump is being fed with an angle of 22 degrees if you do not have the condition of being able to supply a drop towards the pump it cannot be fed a ram pump, that is, if it is a river or an estuary or where there is no waterfall, it is not possible to install one of these pumps. These pumps can only be installed where there is a situation similar to this one where we have a spring that feeds the pump. and the load height should be counted only as the vertical load. In this case we have a little more than two meters of approximately 22 degrees and the length of this pipe is six meters. The pipe must be made of metallic material. Plastic is not recommended because of the water hammer. It is generated in the valve but it is produced in the pipe while if the pipe is a soft plastic pipe the pipe will not cause a powerful water hammer to cause the overpressure that produces the pumping. So that in the first instance now well, what would be the maximum pressure of this pump if we could not see it here since we do not have a discharge at a high point like It is evident that we are going to do it by means of a pressure gauge here we have a pressure gauge perhaps if the intake is brought a little closer we can see a manometer How much is the most efficient that a pump can work with a head of two meters, this pump should work at its point of greatest efficiency between seven and ten times its height, that is, with a two-meter drop we can reach 14 or 20 meters at its point of best efficiency, that is why the maximum height that a pump can carry will depend on the height of the original load here Two meters But if, for example, you have 30 meters or you have 20 meters of vertical drop, if you have that vertical drop, the pump is going to multiply that drop, so the maximum pressure at the maximum head always depends on the height. So how do we do with the manometer, even if we do not have the slope or we have the connection to the high point, we can see that the manometer comes from a scale of psi and bar commonly, but we are going to look at the scale of bars and we are going to say that each pair is equivalent to 10 meters of height, that is, in reality they are 10.3 meters , but for this practical case, as a rule of thumb, we can easily count as each bar It is equivalent to ten meters of vertical vertical height. Only we count the vertical component. We do not count the distance because many times they ask, well, it raises 60 vertical meters but I have 800 meters of travel . It can be easily solved by placing the appropriate diameter of pipe. If we place an adequate diameter of pipe, we can carry the water over long distances. So the vertical component is the most important and the most vital. Another important thing is that in the discharge we cannot put material that is low pressure if we want to take water to 60 70 meters 80 vertical meters we are going to have a high pressure affecting the discharge pipe So we have to be quite careful when considering the choice of material here I have put material plastic and this low pressure hose because it is simply a test, no, but it is not the most recommended, so the installation. How is it, we have the inlet pipe, we have the inlet valve, and in the discharge that is connected to the tank, we must put a t with a pressure gauge and a cut-off valve and then we put the pipe or hose that takes the water to the destination, the discharge pipe, then the other question is this pressure gauge. What scale should this be? This should be according to the height you want to carry. water, if, for example, you want to take the water to 70 meters, that is equivalent to 7 bars. So you have to look for a pressure gauge whose scale is approximately 14 bars 14 bars 16 bars, that is, twice 2.5 times more than the pressure. of the total height let's see this pressure gauge this pressure gauge reaches up to 11 bars 11 bars So for each bar we interpret that there is 10 meters of height Yes this pump all its plans all its dimensions You can find them on my website www.rubenfcobos.com where there is not only this pump that is one and a half but we also have the 2-inch one, we have the 3-inch one and soon the 4-inch one but you can find it and you can purchase the plans for a fairly economical price and you can carry it out successfully. your project So now I am going to start the pump with this valve closed with this valve closed completely we are going to start it and we are going to check what is the maximum pressure that the manometer reaches with the start once the start is given then there the valve begins to make the impact of the ram and we can see that the pressure begins to increase it begins to go from one bar to two bars two bars indicates that we could already have an equivalent pressure to take the water to twenty meters And we can see that it continues to increase Obviously with zero flow because we have this valve closed but we are going to take the pump to its maximum pressure here this tank is accumulating the pressure to a certain extent but we are going to see what the maximum pressure is well And that pressure that we are going to read here we can interpret that It will be the maximum pressure of the pump so we see that it is already reaching four bars, that is 40 meters of pressure and well, if you like this video, I ask you to give me a like and subscribe if you have not done so yet because here We see all the topics of hydraulics and pumps explained in a simple way, then we continue to see that it increases, it is already reaching almost five bars, the valve continues to make the blow, that is, here there is a pressure that is already quite important with five bars of pressure, we can see that It is a fairly important pressure, so with two meters we are practically already reaching almost 60 meters of pressure. This is maximum pressure. It is not the most expected working pressure, the most optimal or the most efficient, right. So we already see that it begins to stabilize at seven. bars means that with only two meters this wave would be able to carry water up to 70 meters high from the pump 70 meters. So it is already reaching the maximum pressure with two meters it even passed the seven bars, that is, it passed the 70 meters of water high let's close Here we are going to do a here we close it we still have retained here in this part we have retained pressure Well this is a pressure that is a little high if not even a little dangerous for this pipe or for this hose It's not high pressure so I'm going to open the valve a little to get water. Look at where the water rises, the pressure is quite strong and obviously the pressure is starting to drop because the pump was deactivated but we can continue activating it and we're going to close here and we are going to pressurize now with the valve open and with this with this Nozzle closed so we can see here the Well here what is happening too It is that this is swelling This is accumulating pressure because it is a hose that cannot withstand high pressures only for this test So I'm not going to take it to its maximum pressure Because it would not be advisable, we could have an explosion in the hose and that's not what we really want here, but we can already see that if it is the pressure that it has, we are here In 30 meters of pressure or three bars, why doesn't it go higher? because the hose is swelling, it is swelling. So it is containing the pressure but here we open it we can Raise the water to more than I don't know, up to more than 10 meters the jet. So this is the way that we can know how high the water is reaching. water when we have a ram pump we must install it is recommended to install a pressure gauge And with that simple rule that for every bar 10 vertical meters we can interpret to what height the water is reaching no I hope you liked this video and yes You want to know what the details are and how this bomb is made up inside. I leave my video here for you to click on. And also if you are interested in watching it. To buy the plans you can also go to the link I left below in the first comment. I thank you for staying until the end of this video. See you next time.
