Exactly, even when the battery isn't charged you can see air in the chamber. Liquid pumps need to be primed. It will probably also slow the engine down a bit but I doubt the prints can hold.
Also needs to change the inlet and outlet. The inlet piping does not need to be necked down right at the inlet and the 90 degree bend needs to be have a larger radius, this also causes cavitation as it throttles centrifugal pumps a lot at the inlet. The outlet needs to be longer before the nozzle is put on. All this will increase the pumps efficiency. As long as the water level is higher then the upper most part of the volute is will self prime and air will get pumped out. But he also needs to start it a little slower and potentially give the veins of the impeller a larger radius as well as making it a “semi-open” impeller.
@@marv8481 ALSO: it looks like the elbow to faceplate seal is leaking, so it's not only cavitating, but sucking in air, which is why it was able to WAY overrev, and explode.
idk it could be because you can use a fire extinguisher in case anything happens and stay way, however at 60,000 rpm it can fling anywhere. Also it could fail at any moment.
Water is not that compressable, however, gasses, are. If you have a pressurized cylinder of gas and discharge it into your sealed reservoir, the liquids will be accelerated out at a high velocity. The nozzles can then be optimized to direct that water. FDM nozzles may be better for the pressure than resin ones. They have more give. Do this before you mill something out of metal.
This is also why working with high pressure fluids with air inside the lines is quite dangerous. If the hose bursts you have a super fast stream of hydraulic fluid coming out and it can and will pierce your skin. Whereas if you have a system with no air and something bursts it’ll just release a small amount of fluid, given that the hoses are not expanded too much.
@@amalirfan Yeah I’ve seen a couple people who injected themselves with hydraulic fluid accidentally and it’s a very very bad situation. Those hydraulic lines had air in them which made it 100x worse.
I have 13 years experience in the RC hobby and when you brought out the "monster" motor, I nearly shat myself and thought, "he is gonna hurt himself". Then you did your first test and I was like, "HOW TF IS IT NOT BLOWING UP?!?" then you charged your battery lol!
@@ThePower1037 my RC has 3600w motor. You should see the panic at hardware store when you ask for connector capable of 900A lol. For reference 13A is max for anything in a UK house
Your main problem here is that the pump is partially full of air when you turn it on. This creates a lot of bubbles, turbulence, and low and high pressure regions. You could probably get a better kickback if you filled the pump with water completely before you turned it on
@Integza Some ideas to make this a bit more effective: 1: A slower, higher torque motor might actually be appropriate here. If you look at your footage inside the centrifugal pump, you see a lot of bubbles, these are probably due to cavitation, which is robbing you of output pressure. 2: Your impeller appears to be backwards. 3: You probably want your impeller to get closer to the walls of the pump.
anatomy of an integza joke: Well worded scientific explanation of how things work followed by example meme. its the reason i subbed! juxtapostion humor is best humor
Well, if you put this in a boat and put the turbine underwater without the chamber then you get a regular boat motor 😁 Also have you seen how the jetski works?
@@Leroydv97 in short, yes. It just won't be able to create a lot of head pressure, so there's quite a limit on how tight the nozzle can be without losing significant amounts of efficiency.
It only seems to explode when air gets into the system, maybe increase flow or pressure into the inlet of the motor? Maybe put the motor acrylic side up and mount the reservoir directly above it, i think that might be the easiest way to increase intake pressure. Cavitation will prolly still occur at high speed tho so idk 😅
You know had seen a couple of your older videos and i wasn't really sure how much i liked them. But now you're one of my favorite engineering channels the amount of effort you're putting in your videos is really amazing and you have really found your stride man. Congrats
Those things don't really work below the speed of sound, so you couldn't really make a video out of them, as you can't use them in any kind of project, unfortunately. "Here's a 3D-print of a ramjet. It looks nice. The end."
@@IT-kone they do! Ramjets actually stop working at the speed of sound. They work pretty nice even at around 300-400 kph. You could probably make a low speed ramjet even to work at like... 100kph or something. Still fast but you could at least test it out.
Video idea: Since you seem to love rotating forces, let's exploit the momentum. Build a gimbal with 2 rotating disks shifted by 90 degrees (X and Z axis stabilization) and use their momentum to cancel the vibration induced by the camera operator.
Video idea: Let's go on with micro! Print a 3D microfluidic TESLA valve and lets see how it works. By the way, from less important to crucial; * You should change the propeller design. * You can increase the thicknesses to avoid fails. * You must increase the downstream length and decrease the diameter of the nozzle. So that you can have a smooth flow. (remember what you were holding in your hand at the begining of the video). * You must be sure of filling the pump with water totally before running. Otherwise, this will be a demonstration of what happens when you run your pump with two phase flow (gas and liquid).
Future video theme: instead of using liquid fuel or solid fuel, you should use a semi-solid fuel/ slurry like coal-water slurry, which is just a bunch of fine coal particles suspended in water, and is highly combustible.
Actually, I think the pump would work better if the impeller was horizontal, so the water would not have to flow "up hill" to fill part of the pymp housing ... fwiw
Even if the pump was primed there is still a good chance cavitation would happen. He needs to have higher pressure coming into the pump. Raise the water up or increase air pressure on top of it to increase the NPSHa.
Priming a centrifugal pump is required only when the pump is above water level. In this case, that's not true, so priming isn't needed or more accurately it was already primed. Cavitation did happen tho, because of the bad design.
Video Idea: Put a water jet on one side of the skateboard and a jet engine on the other and have them push against each other to see which is has more thrust.

I search alot on UA-cam and was not able to find any scientific test on this method, what are the propreties of this type of material ? are they magnetic ? can it conduct electricity ? are the mechanical proprieties similar to steel ? and finally: what temperature can it handle ?.

Well I think you should go even more simple with the “throwing stuff for propulsion” and make a catapult or cannon powered skateboard. The catch: the projectiles are tomatoes (of course).
Id honestly like to see this redone, with a more efficient design and a lower power motor, I feel like that would be the key to your success. Also better sealing of all intake area to reduce air binding would be incredibly helpful and a longer nozzle to allow the pump to build head pressure.
I think you should revisit this topic. Take a look on how a turbo impeller is designed. You can get more structural support on your blades by adding a plate close to the motor side and if you put the blade on a diagonal you could get more thrust out of a less powerful motor.
What little I know about fluid dynamics, mechanics and displacement is not much, I would suggest that either there are too many forces being enacted upon from various inputs. There are air pockets created inside the housing of your pump as it spins, this adds additional varying stresses on all your components as centrifugal force has varying effects on materials when run through varying mediums. Thus compounds all stresses and that is why it breaks. For fear of leaving too much to read here: Try adding "step up" pumps from your feed tank toward your 60 000rpm pump. This should fill the gaps better and be beneficial in adding some equilibrium throughout the running process. I can make more detailed suggestions if you are keen.
I am not sure if thats possibble, hopefully other commenters can help! I'm sure Integsa can do it anyways >:D Right commenters? May the Tesla be with You.

You could make a 3d printed BB-8 droid.(Star wars) I was building a BB-8 droid 2 years back which I left incomplete because of its body.Which was made from paper mash,wood glue and, canvas cloth ,cutting strips of paper and canvas and pasting it on a beach ball layer by layer. But after a lot of work i made a 5mm thick sphere which eventually wasn't strong enough and also was not perfectly round .so I decided to add epoxy coating on it but even after that I noticed that after cutting the ball In half to put the internal mechanism inside, the body was just too flexible and can not be used.. so I searched on the internet for some solution and I came across the design of "James Bruton" which was nice and sturdy but 3D printed. I made the internal mechanism with Arduino,2 powerfull dc motors to run like a hamster wheel. which would have worked if I could could make the body smaller may be 10-15 inches in diameter . Again I faced another problem that how will I charge the battery. which will be inside the sphere and how will I put the half cut sphere back. So I left the project for a while. Now after 2 years i have plans to redesign it's internal mechanism so I can easily charge it and make the body out of cement ( which I think is again not a good idea ). Anyone having any suggestions please comment
I've seen a few people comment about the direction of the impeller blades... Impeller blades can be forward-curved, backward-curved, or even straight. Broadly speaking: --Forward-curved blades produce flow tangentially to the impeller, as the blades are actively pushing the fluid. This type of blade can easily exceed the drive rating of a motor at higher flow rates if improperly designed. These really need scroll/ volute housings to be most effective. They are better for high flow rates at low running speeds and lower pressures. --Backwards-curved blades produce flow radially, as the backward-curve creates negative pressure behind and along the length of the blades, and positive pressure in front of the blades. They offer significantly higher efficiency than forward-curved blades, function well at higher pressures, and offer greater suction characteristics as a result. They also don't need volute casings to be effective, though work better with them. --Straight blades are a bit of a mix. They are rarely used as they lack the benefits of either design and offer lower blade stiffness thanks to the lack of curved geometry. For this application, the backward-curved blades are certainly more appropriate. The pump would definitely benefit from being primed, ie filled with water before running. The air in the impeller is significantly hurting performance. Plus the thing might not explode if it spun under a higher load, which would be the case if there was no air on the system. In industrial applications, pumps are almost never run/ started 'dry' for these exact reasons.
I love this. The inefficiency here is staggering. A 2,000 watt motor and you could piss faster than that water moves. You are really choking your pump with the inlet pipe being way to small. Eventually you should make a proper pumpjet! That would be awesome.
@@davidroberts1852 As integza explain at the start of the video, jet engines work by throwing stuff backwards, he has tried, throwing gas backwards, and now liquid, he should try making it solid, he could try, for example, to through heavy balls using a small automatic canon, it would be incredible hard and inefficient but I would love to see what he comes up with

When RPM is too high You will get a lot of air trapped inside, submerge the pump in water 1st.

A lot of the pumps energy was wasted due to air being on the pump. It needs to be properly primed first.
I'd say more energy was wasted by rapid unscheduled disassembly.
and centrifugal pump just for moving a lot gasses/liquids, not for pressures

Well I think you should go even more simple with the “throwing stuff for propulsion” and make a catapult or cannon powered skateboard. The catch: the projectiles are tomatoes (of course).
Id honestly like to see this redone, with a more efficient design and a lower power motor, I feel like that would be the key to your success. Also better sealing of all intake area to reduce air binding would be incredibly helpful and a longer nozzle to allow the pump to build head pressure.
try creating a turboprop engine fueled off of propane,
especially now that you have a CNC machine to create metal parts
I think you should revisit this topic. Take a look on how a turbo impeller is designed. You can get more structural support on your blades by adding a plate close to the motor side and if you put the blade on a diagonal you could get more thrust out of a less powerful motor.
Project Idea: "I think you should make bicycles running using small jet engine". I hope you will make it...✌🏻
Look up Colin Furze, he did this and it turnt out very cool!
He already did
VIDEO IDEA: build a single chamber piston engine with TOMATO CANS and use it to SMASH TOMATOES!
Video idea: use ur water pump to make the worlds most powerful watergun, and break the record and destroy tomatoes
I really wonder if this works the other way around. Maybe use a bigger version of an SuperSoaker to create the water jet to push the skate board.
You should create the tomato trillagy where you have a video of how the fued against tomatoes started
and now a lesson about "cavitation" :D
yeah xd
Video idea: Head to head water engine vs propeller or turbo air engine with the same brushless motor. Btw Great video!
Theme for future video: make a 3D printer using a 3D printer.
i like the way you present the work :)
Theme: How about make a small petrol engine.
You mean like what a lawnmower or chainsaw uses?
To add to that, make the engine supercharged or turbocharged.
video idea: using 4 jet engines to make a hovering platform (similar to a quadcopter!)
Nice idea!
He only took idea of hovering jet ski name is fly board , I know this engine before 😀 never thought to make a vedio 💩
video idea: make a Biogas Steam engine
What little I know about fluid dynamics, mechanics and displacement is not much, I would suggest that either there are too many forces being enacted upon from various inputs. There are air pockets created inside the housing of your pump as it spins, this adds additional varying stresses on all your components as centrifugal force has varying effects on materials when run through varying mediums. Thus compounds all stresses and that is why it breaks.
For fear of leaving too much to read here:
Try adding "step up" pumps from your feed tank toward your 60 000rpm pump. This should fill the gaps better and be beneficial in adding some equilibrium throughout the running process.
I can make more detailed suggestions if you are keen.
video idea: Making a hovercraft with this pump on it in the next video.
May the Tesla be with You.
Tomatoes are disgusting!
I am not sure if thats possibble, hopefully other commenters can help! I'm sure Integsa can do it anyways >:D Right commenters?
May the Tesla be with You.
@@justbeeeb2061 They are discusting!
@@zsoltvarga3950 Actually factually correct! WOW
@@zsoltvarga3950 Remember Tomatoes are disgusting 😉
Well... You said it.
*"can CNC metal"*
Guess you got to revisit this pump after you figure that out!
or just cast it from aluminium, that would make an interesting video
Integza, I'm surprised you didn't 3D print a Tesla turbine. They have been used as pumps too and are easy to make.
Have you not seen(and then printed) the three designs he made?
@@stanulbrych220 They are not the bladeless turbine design Tesla invented.
@@htmagic I know, but isn't the point of his videos trying/inventing new things?
for higher pressure use a positive displacement pump
Video idea: strap a jet to a plane. We need more air travel.
u can make a turbo prop engine or a vectored thrust rocket or turbojet engine
Try making a steam-powered car!
Have a boiler, that feeds into a turbine, which then powers the wheels.
Ya know....this was done over 100 years ago...nice idea and would love to see again honestly
Video idea : You should build a small submarine and see if you can shoot rockets underwater. Because underwater footages are always cool and torpedoes too !
Video idea: make a rocket engine that uses a Venturi to mix the fuel and air
or make a venturi that uses an engine rocket to fuel a mix of air
So basically, a rocket engine with a carburettor
You obviously need a better propeller for the pump!
(Flat type should be good) 😁👍
Idea: Strap a high power laser to a CNC/3D printer and see if you can cut a 2x4!
You could make a 3d printed BB-8 droid.(Star wars)
I was building a BB-8 droid 2 years back which I left incomplete because of its body.Which was made from paper mash,wood glue and, canvas cloth ,cutting strips of paper and canvas and pasting it on a beach ball layer by layer. But after a lot of work i made a 5mm thick sphere which eventually wasn't strong enough and also was not perfectly round .so I decided to add epoxy coating on it but even after that I noticed that after cutting the ball In half to put the internal mechanism inside, the body was just too flexible and can not be used.. so I searched on the internet for some solution and I came across the design of "James Bruton" which was nice and sturdy but 3D printed. I made the internal mechanism with Arduino,2 powerfull dc motors to run like a hamster wheel. which would have worked if I could could make the body smaller may be 10-15 inches in diameter .
Again I faced another problem that how will I charge the battery. which will be inside the sphere and how will I put the half cut sphere back. So I left the project for a while.
Now after 2 years i have plans to redesign it's internal mechanism so I can easily charge it and make the body out of cement ( which I think is again not a good idea ).
Anyone having any suggestions please comment
Idea: using solid objects instead of water, I want to see shooting tomatoes
🍅🍅🍅💨🛹😂😂😂
good idea
Video idea: When you perfect metal jet engines, send a rocket into space!
This requires shit ton of papers and bereaucracy
8:28 Im like 90% sure you PUT the fan the opposite way. Shouldn't it be the opposite way so that it can "grab" more water?
I've seen a few people comment about the direction of the impeller blades...
Impeller blades can be forward-curved, backward-curved, or even straight.
Broadly speaking:
--Forward-curved blades produce flow tangentially to the impeller, as the blades are actively pushing the fluid. This type of blade can easily exceed the drive rating of a motor at higher flow rates if improperly designed. These really need scroll/ volute housings to be most effective. They are better for high flow rates at low running speeds and lower pressures.
--Backwards-curved blades produce flow radially, as the backward-curve creates negative pressure behind and along the length of the blades, and positive pressure in front of the blades. They offer significantly higher efficiency than forward-curved blades, function well at higher pressures, and offer greater suction characteristics as a result. They also don't need volute casings to be effective, though work better with them.
--Straight blades are a bit of a mix. They are rarely used as they lack the benefits of either design and offer lower blade stiffness thanks to the lack of curved geometry.
For this application, the backward-curved blades are certainly more appropriate.
The pump would definitely benefit from being primed, ie filled with water before running. The air in the impeller is significantly hurting performance. Plus the thing might not explode if it spun under a higher load, which would be the case if there was no air on the system. In industrial applications, pumps are almost never run/ started 'dry' for these exact reasons.
@@KenanBaskott Thanks for clarification. This is what I was wondering about.
@@KenanBaskott quality explanation
@@KenanBaskott explanations like these are so rare
This video helps figure out a couple ideas for a water jet board for traveling up the local river
make two of those, feed them with hoses, and attach them to gloves, and wherever there is water you can have jet hands.
Video idea: Do it again with metal and destroy your beloved new CNC in the process !
Video idea: make an electric rocket engine
I love this. The inefficiency here is staggering. A 2,000 watt motor and you could piss faster than that water moves. You are really choking your pump with the inlet pipe being way to small. Eventually you should make a proper pumpjet! That would be awesome.
Video idea: make a solid exhaust jet engine
Solid exhaust?
@@davidroberts1852 As integza explain at the start of the video, jet engines work by throwing stuff backwards, he has tried, throwing gas backwards, and now liquid, he should try making it solid, he could try, for example, to through heavy balls using a small automatic canon, it would be incredible hard and inefficient but I would love to see what he comes up with
@@keeeeevin1474 right. So solid projectiles. I feel like exhaust is the wrong word for that application
