Can u 3D Print Pressure Washer What is Running on Water Pump? (Experiment)

Is this possible to 3D print the pressure washer that is running on the water pump? In this video, u will see how I try to make it and how well this performs. Making this video took me a lot of time because I run into a lot of different problems. The water pump that I have designed is the most complex water pump that I have ever made and free .stl files in down below. Water pump and animation are made in fusion 360.

I hope u enjoyed it. Please leave me a comment will u wanna see in future more experiment videos or tutorial style like most of these channel videos. Thank u for watching!

I learned something about pumps in school (thermodynamics), so if you need really high pressure you have to change the design.
Usually high pressure washers use piston driven pump that is better to make high pressure with lower volumetric capacity.
This design that you use is makes high volumetric flow with small pressure.
I have some formula how to calculate material flow and speed on different impellers.

1. Ask your neighbors if you can borrow their pressure washer.
2. Take it apart and 3d print something similar.
3. Return your neighbors pressure washer and build your own copy.

nice background music. i dont even like metal anymore but this just works. great videos as always man. thank you!

You can start out by using a smaller hose, then maybe try a higher gear ratio and a closed impeller or piston design, but if it’s a piston design you would have a lot of leaking problems because you’re 3D printing it. You should also try a lily impeller because they look cool and make a whirlpool

2 things that will help. I work on dishwashers and rebuild pump motors when leaking.

1. Sealing pump housing.
either need to make a gasket out of gasket material cork, create pump housing with a grove for o-ring or when using rtv make sure you spread a thin coat on each side let it setup for 2 min put together finger tight let set up for 10 to 15 min depending on rtv used then torque housing down. Good rtv will seal water tight within 20 to 30 min to use with water but requires 24 hours for full cure time.

2. You need a shaft seal and a flinger on the rod behind the housing between the housing and motor. Shaft seal prevents water from leaking to motor. In event shaft seal fails, flinger is there for added insurance to not ruin motor.

You need a positive displacement pump, usually a pressure washer has a multi piston pump, usually 3 pistons on the cheap pressure washers . There pretty beefy castings and bearings involved .

If u want hi pressure a centrifugal pump is the worst. If u want lots of volume centrifugal is good but if u want pressure ur will have to use something with a piston, diaphragm, or the highest pressure a plunger pump

You will want a closed impeller design with compression profile, and the inlet can be as much as 30 times bigger than the outlet. The rpm on that thing needs to be alot bigger. And you want to try prob. printing labyrinth seals in the edges that you will with silicone when you screw it all together. Fun project tho. :)

I would actually try to make an air pump to increase pressure in the tank and allow it to send excess pressure through the tube. Air is easier to pump.

You either need very sloped fins or a very small impeller, so you get good pressure. Pressure washers work by having lots of pressure a d turning it into speed with a small nozzle, instead of forcing water through the hose at high speed in the first place. I recommend a small impeller without reduction, your idea of moving the impeller slower just allows for pressure to escape in the turbine housing

[korishan]

A pressure pump isn't rotary and use vanes, like your builds. But it works more like a car engine with pistons. This is what allows it to build up pressure as it can turn rotational energy into high torque to push the water. Also in this build, there is a pressure valve which is controlled by a spring. This would help keep the water pressure from blowing out the seals.
1 piston will create a pulsing effect 2 pistons in parallel, but alternating strokes, will have smaller pulses, but more flow. You could do 3 or 4 pistons to get stead flow of water.

Thanks for the commentary, they truly help. A+ for your English.

Helical Rotor Pump, and a way smaller hose. If you decrease the output diameter it will increase the pressure.

TL;DR: use a mains power supply with max wattage of the motor and direct drive a 3 dimensional radial turbine

perhaps a 3 dimensional radial turbine may be more efficient than your 2 dimensional turbine. It may also reduce the complexity of a multi stage turbine as has been successful in your previous videos since it is an equivalent machine that's integrated into one (non-linear) turbine. Proper angles and sizing of the 3 dimensional radial turbine can also substitute a gear and have direct drive from the motor which may be slightly more efficient but definitely less prone to breakage or leakage. This will help overall with efficiency but you will need much higher energy and I don't know if there's any way around that. looking at the energy of chemical pressure washers or even modest electrical AC washers there is a large gap.

Thank you for these videos I appreciate your experimentation and have gained insight into my own projects.

Green hose at 6:56 is kinked, cutting off most of the water flow and increasing back pressure to pump making it leak worse.

[tejae]

These days they make a simple hose “thick balloon like hose attachment” it’s not extremely powerful but more than your standard hose nozzle. It does give me some ideas for 3D printing and thanks for this video.

If you want better pressure you could make a closed impeller with angled and curved blades. But most pressure washers use a piston pump so it's positive displacing meaning that if you plug off the water flow it would build pressure till the motor can't turn. But they put release valves in them so that doesn't happen

[akselwilliamdanenbarger]

It's a great idea❣😉 But if you whant more power try to make the outlet small or flat. This will make a small striam of water but will increase the pressure a little bit more. And a pressure tank also help... A purchased quality high-pressure washer has a powerful motor, which pumps pressure into a pressure tank (that's why high-pressure washers are so big... ) Have you heard that a purchased high-pressure washer switches OFF when the pressure is reached in the tank, and ON again when you start using the water ? I just merchandising it to proove my teory. The ON and OFF switching is just to save energy while not in youse (READY but whaiting), and for safety to not put TOO MUCH PRESSURE in the PREACHER TANK.

[hikecraze]

the design you are using is hi flow/ low pressure. good for equal pressure transfer. but to get what your after takes low flow into high pressure. using a baffle system and/or multistage compressors you may be able to up the pressure but will need sealed pressure vessels for any kind of sustained use. my suggestion take an old air compressor and convert that into your pump with a few water tight modifications. only issues are 3d printed parts can not handle pressure well and priming the system avoiding vapor lock

[paulrowe]

For the purpose of pressure I would recommend using either a Gear pump or a Piston pump.
