Nice, for next version, you may try a logarithmic spiral for the volute shape instead of the linear spiral, Physics say it should be better, something about constant angular momentum for fluid elements along the trajectory. Glad you are taking care of the leaks problem better now :)

A flow meter to put some actual numbers on the pump performance would be awesome

Sweet build. I work on pumps for work and all of the pumps that I work on, have the shaft seal on the inside of the pump. The bearings are inside the motor which is outside of the pump. There are no bearings inside of the pump. The shaft seal faces ride against one another. One has a ceramic face and the other has a graphite face. Half of the seal mounts to the backside of the impeller, in a recessed area for it, and the other half is pressed into the pump housing. Keep up the great work though! Loved this project!

This blew my mind. Graphite makes absolute sense considering the shear strength of the atomized carbon is actually going to be significantly higher than in any oil. I've never thought of using graphite for high pressure, high speed application, but with this explanation and the knowledge we have of "graphene" it makes a TON of sense. I wonder if using a material that not only was dense, like ceramic, but also repellent to carbon in chemistry could improve wear. The simple solution of graphite seems almost unbeatable though.

@@SpadeNya carbon is used for its self lubricating properties. A carbon rotary running against a silicon carbide stationary is the coolest running face combination. Alumina ceramic like mentioned in the above comment is a poor conductor of heat and will create a condition called heat checking if not kept cool. Other materials used for faces are antimony carbon, sintered and reaction bonded silicon carbide, tungsten carbide, PTFE, and in some cases chrome oxide plating. Most smaller pumps with shaft diameters below 1.500" use cheap throw away seals from the factory which are around 300 dollars. Larger pumps will use more expensive cartridge mechanical seals that can be rebuilt and can range anywhere from $1,000-$50,000 depending on size, metallurgy and elastomers used for a particular application. Sorry for the wall of text, I have a lot of experience with process pumps and rotational shaft sealing and couldn't help myself. Lol

Hey, new here but as a automotive mechanic I think I might have something to add. When you're installing shaft seals, you want to install them so that the pressure they are supposed to contain presses against the sorta V shaped wiper that seals the shaft. This makes the seal use the pressure it is supposed to contain as pressure to keep itself sealed. At 2:42 it looks like you installed the shaft seal backwards vs what I described, which is a pretty common mistake people make with crankshaft seals in engines as well. Cheers.

I'm so glad I came across this channel. Really interesting stuff.

Man, you are in top 3 channels for 3d printing because, i like that you TEST and SHOW NUMBERS of everything, thats so important, and making the reviews versions and sharing your process of thougt, cut the youtube bullshit by showing numbers, almost everything is pure numbers (sry for my english)

so the reason this worked so much better than other pumps is because pumps are extremely sensitive to impeller to housing clearance, and this sensitivity becomes more and more important as you make the pump smaller. The enclosed blades are basically like a perfect fit; the housing in this case still matters but its easier to add more area to it to get a better seal with poor tolerances.

A very impressive design especially with the gearbox fitted that shot the water so #$%#* high up.

You are awesome man! I really like your 4 motor gearbox.

Would you print one of those laminar flow nozzles and attach it to the outlet. I'm curious as to if you'll get laminar flow or if you need to have a tube between the pump and nozzle

More important. Pressure and pump heights. What are most pumps used for? Pumping from low ground to higher ground. Volume will always be second priority 😅 any other engineers agreeing?

@platinumsky845

Жыл бұрын

I disagree because it entirely depends on the application. some pumps are made for static pressure, some are made for flow rate, and some are designed for a combination of the two. Saying "volume will always be second priority" is a glaringly shortsighted perspective on pump design.

Another great video! Would love to try this design at our nearby creek 😉.

This is cool, i'm trying to build one, but what size are the shaft and bearing/seal? Thanks!

i was thinking of using this as an underwater brush, the brush being attach to the shaft and the motion being delivered by an electric pump that will suck water thru the housing... do you think it could work?

Have you tried printing the Impeller INSIDE the housing? i.e. one print? Sure you might need to change way things are mounted, attached, make some geometry changes, etc. But it might help reduce sealing issues. Managed to print impeller in my design "just above" the inside of the housing and was able to separate it fairly quickly/easily.

Great video! Throwback to the horrors of Turbomachinery course during my ME though 😂

You should buy a flow meter that attaches to a hose for these tests

Attach the rigid flange coupling to a horseshoe thingy for better performance

now you need a small boat or jet ski to test this pump on. probably not going to fly on it but you'll see how much power it has.

You need some rigid hosebucket coupling

put a thin bead of hot glue down where your housing joins together. This will help seal the housing and increase the pumps pressure.

can we get a video comparing each pump's pressure? like see how high up each can pump water

You should try putting one planetary gearbox in it

Hello, nice design. You could use closed bearings, they're for fluids etc. they cost about the same. Regards

*_Rigid_* *_Flange_* *_Coupling_*

that is very impressive. good job. I have a questions though. usually, in compressors, the housing starts big and is small at the outlet, to build pressure (if I remember correctly). it is supposed to be the same with a water pump, or is it different because water is incompressible?

@2009dudeman

Жыл бұрын

A water pump and air compressor are both fundamentally the same thing. Both are fluid pumps. Their design only differs because of what we want the result of that pumping action to do. With a water pump the primary goal is to move water quickly, so we prioritize flow out of the pump. This is where centrifugal pumps (non-displacement pumps) shine, because water flow is inversely proportional to outlet pressure. So our goal is to keep pressure at the outlet as low as possible. This means we don't want very much restriction at the outlet. Remember pumps do NOT create pressure, they create flow. It's the resistance to that flow which creates pressure. For a water pump (excluding pressure washers, which we will cover later), the main goal is to create as small a restriction as possible at all points in the pump. And air compressor is different in what we want out. We care more about what pressure it can generate over how much flow it can produce. This is for two reasons, air demand for a compressed air system in most cases is intermittent, it's also easy compared to water to store a large amount of gas in a pressurized container. Whereas water requires an accumulator that comes in one of several forms, they are almost always more complicated than a tank with a threaded hole. Since non-displacement pumps lose flow as pressure builds, they make good pumps for air until you actually hook them up to something. Think about those commercial floor blowers, they are just a form of centrifugal pump just like the ones Let's Print makes. When you feel the air coming off them it's clear they move a LOT of air. However you can pretty much use a piece of cardboard to block off their outlet, they don't produce any flow when the outlet resistance increases even slightly. So for an air compressor where we usually want 100psi or more at the outlet, we move to a positive displacement pump, a pump that for every revolution will always output the same volume regardless of outlet pressure. These are found usually in the form of piston pumps, but you can also get vane pumps, diaphragm pumps and many more. The end result is that each displacement pump creates a fixed amount of flow. For an air compressor this is great because it means when the air tank starts building pressure, the flow stays the same, so the tank fills at a nearly constant rate. This does have the side effect, unlike a non-displacement pump that as outlet pressure increases, stress on the pump itself and the motor also increases. Without safety controls this could result in failure of the pump, which can be highly explosive in the case of air systems. As a result outlet size doesn't matter as it cannot really affect flow, however the larger the outlet the more surface area the fluid inside has to press against and the stronger and more expensive the outlet must be. A pressure washer for example uses a displacement pump as we desire outlet pressure over outlet flow, so we see a small outlet due to the high working pressure even though it's a water pump. Another side effect of pumping dense fluids is that even small restrictions cause pressure to rise quickly, as such with positive displacement pumps that move liquids we always need a high volume pressure release as once we plug the outlet such as closing the sprayer on a pressure washer we must bypass the full flow of the pump or use a pressure activated switch that disables the pump entirely (not important to the discussion but I thought I would add it anyway). This is all a very basic overview, but it's still educational.

@@2009dudeman I have to somewhat correct on what you said. For the most part, great foundation. The inlet on centrifugal pumps that are pipe fed are usually larger in diameter than discharge since the desire is for the inlet to have lower flow resistance, thus maintaining higher pressures through the system before reaching pump inlet. This is crucial since the pressure has to be large enough so as to avoid cavitation on the first stage impller vanes. The discharge side diameter is usually governed by what discharge pressure you want your under load system to operate at and the flowrate needed. The larger the diameter, the greater your pressure output could be, but this may ruin efficiency of the pump. That being said, a 5' diameter pipe is not gonna lead to a 5000psi discharge pressure necessarily. As an added fun fact, air compressors can be centrifugal. It is common in high flow applications to have compressors with up to 6 or more impellers feeding into each other in series, just like water pumps. These types of compressors may not see pressures as high as boiler feed pumps of the same number of stages. It depends heavily on application and operating speeds but it is possible. Example: Some boiler feed pumps are rated to have a peak operating discharge pressure of over 7000psi and they are the size of a full sized truck when assembled.

@@willpestka2745 I don't know if I would call that as much of a correction, as I would an addition of information. There are various types of air compressors that are not positive displacement, some are even hybrid designs. But that goes beyond the scope of basic pump operation. A compound turbo setup is an example of multistage compressor to provide flow at pressure without being fixed displacement. I've worked on compound turbo systems as high as 120psi, which is higher pressure than many positive displacement compressors. But that's all additional information that gets confusing. Just talking turbocharger AR ratio is more than most master level ASE mechanics understand.
