Gear pumps are actually relatively efficient, work with a high range of different fluids and they have a simple construction and the output is easily controlled. They're overall pretty great.
In the refinery I work in they used a gear pump to pump a slurry of solvent, water and perlite powder (finely crushed volcanic glass). As you can imagine it needed extremely frequent maintenance, the perlite was literally sanding down everything inside the pump. Why they decided to use a gear pump for this slurry in the first place is beyond me, but they finally put in a better suited pump.
@@biggreenblob Yup, despite the properties of progressing cavity pumps being well known where I work, they default to using centrifugal pumps for almost everything. Probably because they're way cheaper. The gear pump I talked about was replaced with a centrifugal pump, it doesn't break all the time anymore, but it isn't theoretically ideal.
I assume English may not be your 1st language so I just wanted to say that I appreciate the effort you go through to make these videos available to those of us that don't speak your or native language you've done great! Thank you!
Thanks. Yes, English is not my first language. My profession is a hydraulic engineer, but I also enjoy doing computer animation. At first I translated the video myself, but it turned out badly for me. Then I turned to a translator and a voiceover, for a small fee they helped me. I do the animation myself, write the text, then the translator makes the translation, then the announcer gives the voiceover. Advertising on RUclips allows me to recoup my costs. The problem is that I cannot assess the quality of translation and sound.
@@hydraulicandpneumaticsyste3253 well I appreciate the effort I know for a fact that ots not easy and doesn't always come together easly either but with time the process will become more automatic and certainly less difficult you keep at it its great to help people gain a deeper understanding

Internal gear pumps are pretty much standard for automotive engine oil distribution. One of the advantages they have (in that application) is that they have no bearings. The inner gear will sit on the front end of the crankshaft, which has its own bearings. The outer gear will free float inside the oil pump housing. The engine oil being moved by the oil pump lubricates everything.
Nope. Oil is distributed across the gears by immersing one of the gears in the oil directly. It is NOT moved by a pump. It is moved around the parts by capillary action between the gears. In other words, the oil is passed from one gear to the next by the fact that it sticks to the gears. When the gear interfaces with the next gear, the contact causes some of the oil to transfer to the other gear.
@@protoborg you might have misread. You're describing the lubrication of a manual transmission. I was talking about the engine, which only has gears in the oil pump and camshaft timing mechanism. Engines are lubricated by pressurized oil from the pump.
Neat explanation it works different than what my 'visual intuition' was expecting. -Fluid flows around the outside of the gears, not pulled through the middle like I would expect a solid object,.
Hi, I am the author of the channel. English is not my first language, you probably understood that. I write the text, then I ask the translator to translate it into English, then I ask the speaker to voice it. I can’t rate good and bad.

@@hydraulicandpneumaticsyste3253 I liked the one you linked more. For me it makes it a little bit easier to understand. But then again it all comes down to preference. Both great videos btw
Just wanted to say that I enjoyed the accent (probably because of my Slav origin xD) I enjoyed animation even more and how much important stuff did you mention and explain in very short period of time. Must say that I love people like you!
Excellent 👍 I would like to build a hydraulic press actuated by the pump+motor. Could you please provide the scheme what components are needed and how should the connection looks like? I mean the correct order of components connection. Thank you
Nice explanation, I always thought they worked the other way around. What I am wondering is: Do the liquids get smashed around and get bubbly and foamy on the output side? Because the moving direction of the gears is exactly opposite to the direction of liquid flow.
The fluid does not flow through the engagement, there is no free volume. Fluid flows around the perimeter. At the moment when the teeth disengage, the volume of the working chamber increases, the liquid from the suction line fills the space between the teeth. Then the gear turns and the liquid is locked in the space between the teeth and the housing. Then the teeth engage and the liquid is squeezed out of the volume between the teeth, it flows into the pressure line.
depends on the viscosity and RPM of the pump. With the right pump, most liquid is pushed away from the teeth and barely moves back to the input. If the viscosity and rpm of the pump are too high the liquid can`t escape that easily and will get compressed by the gearing. This can cause bubbles and foam as we have different pressures and velocities within the fluid.
What I don't get about these pumps is that there are a lot of spots where it looks like the oil is getting compressed, the oil that is used specifically for its incompressibility. The simulated oil even got pushed out of the model at some points in the video
The animation is correct. It is necessary to correctly understand how the liquid moves in the pump. She moves around the perimeter. Through the place where the teeth of the gears are engaged, the liquid cannot flow, so there is no empty volume. I want to release a short video where this issue will be discussed in more detail.
So like if you lost access to say bottled water, do you think it would be difficult or even possible to setup a primitive version of that first pump to gather water?
It would be nice if the video showed the pump actually working. Not completely blocking a perfectly good flowing stream and showing no pump action whatsoever.
I hear my coworkers say "gearbox of a pump" all the time, even when they are talking about centrigual pumps and conveyors. What is a gearbox? I cannot find the answer anywhere. Please help
Is it just me or does the narration sound really aggressive, like I feel like someone is barely containing their rage that I asked a question, like "Oh shit, sorry! I just wanted to learn!"
I want to know very details about closed loop hydraulic piston pump and also other thing like All types of valves used in gear pump. Hope will find all the details in your channel Thank you
This video is excellent! I’m just getting into hydraulics and this is the most clear explanation I have seen of the operating principle of a gear pump. Does cavitation occur enough for it to be worth studying?
The way you pronounce things sounds like it would go well with intensely flailing hand movements In all honesty though, gotta say your English sounds great. Very informative video too.
The volume of the pump doesn't change. Each gear moves the fluid from one side to the other side. 2 gears filling 1 space forces the fluid out of the pump

Indeed, while attempting a Christopher Walken impersonation
“How inefficient would you like to make your pump?”
“Yes”
It might be energy inefficient, but I bet it can generate massive pressure and probably has really good self priming capabilies.
Gear pumps are actually relatively efficient, work with a high range of different fluids and they have a simple construction and the output is easily controlled. They're overall pretty great.
So what method would be better? These are still being used in cars to this day.

Most hydraulic pumps and oil pumps are gear type pumps.

Yes, the gear pump is not well suited for this industry.
Wow yeah slurries containing abrasives are a no-no for gear pumps. A much better choice would be a progressing cavity pump.

Great job on the animations - they add a lot! The voiceover was good too, I liked it actually. Sub’d.

The pump will not work. The first bearing was put ay the wrong side. The high pressure side was put into the low pressure side.

How It’s Made narrator: “The fluid goes into the gear pump where it is *violently sheared & brutalized* before being sent on it’s way.”

Surely if the water is flowing fast enough to enter the discharge tube, you shouldn't need a pump

Cool...but, this was 9th grade auto shop before it was turned into a daycare for students children.

Does it annoy anyone else that the volume of liquid entering the pump doesn't match what is leaving

These pumps are used in many applications. In engines, they can pump fuel. In tractors and presses, pump oil in the hydraulic system.
