HYDRAULIC GEAR PUMPS EXPLAINED!

How can two little gears can create HUGE hydraulic pressure.
Long term projects here: / ave

[@Kevin-rc5ec]

Dear AvE, your videos have kept me interested in engineering and thus lead me to my degree. You are just the best. Thanks for putting all the work you do into these videos, man!

[@notsure7060]

Good work m8. Gratz on your degree =D

[@ericluffy7970]

Cheers to that. Very cool you found that inspiration

[@flyingjeep911]

Same story with me but ima machinist 🙃

[@srednadahlberg]

Impeccable explanation! And I love how you stress the flow/pressure distinction.

[@StealthPlatypus1]

I absolutely love these kind of videos. Nothing beats the hands on explaining. Please keep these up!

[@JordyValentine]

Hahaha, I laughed way too hard at the click of the tourque wrench. I'm guessing you tourqued it to FT (fucking tight)

[@TINRFD]

Jeff from elderly iron has the same torque wrenches...

[@marccrocker1908]

me too lol

[@GunFunZS]

It took some learning growing up to stop at that click before the fastener said "Ting", and my knuckles chimed in.

[@underourrock]

FFT. That's Full Fucking Tight, for you. Any tighter and you get stripping.

[@ddd228]

GOOD-'EN-TIGHT. Yah .

[@doibing9856]

I've never even considered engineering until i came across your channel a couple years ago. Glad you can share joy of machining with us common folk.

[@MichaelSteeves]

11/16 wrench on a metric bolt. Never change AvE...

[@scarface3131983]

ha..it is a crapsman wrench tho

[@sthenzel]

Just 0.46mm too large, doesn´t matter that much on 12.9 bolts, they´re hard stuff. If the Crapsman dies on it, who cares?

[@duramax78]

Wasn't a wrench it's a torque device....lol

[@XC2long4u]

I use 3/4 for 19mm and 5/8 for 16 all the time, call me a rebel.

[@Scofflaw_k10]

it's 11/16 of the proper torque

[@kdknitro]

Your hydraulic videos is how I discovered you, your infrared heat gun trick is worth its weight in gold. Keep up the great info.

[@davidheaton7740]

I like the cavitation talk. Ive seen the end results of water cavitating a diesel injection pump quite a few times. They love to send steel glitter all through the fuel system as the pump detonates slowly.

[@Hizone1]

This video given me the exact knowledge that I need to know now a days for my project. Lot of thanks for uploading such a brilliant effort.

[@fergusoddjob]

Got a university report on gear pumps and was getting bored of my tutors long winded vijeos without any swearing. Glad I remembered you made a video on these!

[@coreyregier5546]

I'm in first year HET and we just started taking little hydraulic pumps apart last week to measure the displacement and whatever, good timing for this video! Also, I think that's cool that you can flip the input shaft around in case your pump needs to be driven the other way.

[@chbrules]

Love these vids. I'm not a mechanical engineer or anything (just a web app developer), but I love watching technical stuff and learning. I work on my track car, so I guess this sorta falls in line with it. You're seriously the first YTer I'd consider giving to on Patreon.

[@petermof]

As someone who lives in a former colonial outpost, the easiest way to tell imperial fasteners in my garage is by the rounded heads from using metric tools on them...

[@AndyHullMcPenguin]

Another well tested method. Eyeball the fastener, and select the tool you are absolutely certain will fit it.. if you selected metric.. it will be imperial... and if you selected imperial it will be metric. Uncanny.. works every time for me.

[@charredskeleton]

If it's an American car either might fit, if it's a Japanese car metric tools will fit but you hands won't!

[@apuuvah]

Hey... let's all switch to metric! And let's put the steering wheel on the left side as well, while we're at it!

[@wayne5607]

I was looking for a repair video on hydraulic pumps and you came up! VERY COOL! I love your videos! Thanks!

[@NeilvanGeffen]

You're a knowledgeable man! And i'm glad to learn something new from you every video!

[@CharlySick]

+AvE I like this new frequency of video releases. Keep it up!

[@ronroberts110]

Glad you mentioned cavitation. Put your hand underwater and move it from one side to the other really fast. A vacuum pocket will form behind the hand that you can easily see. There's no air in there, but it is a cavity. I have also seen the inlets being pressurized to reduce cavitation. The highest I saw was 100-PSI, and that was on a 3000-PSI system. Great vidya, my friend...

[@GlawberOliveira]

I was so pumped for this video

[@jamesdaniels9882]

Your videos helped me fix my ingersol-rand impact now its helping me understand pto’s that i work with daily better. You got one for everything dont ya

[@ownedpatrol]

Just picked up a little scrap honor pump from work that I'm gonna disassemble and attempt to fix. Your videos definitely helped get me interested!

[@mehmetalikocak3843]

Aliminyum ana gövdede çizik varsa o pompa ölüdür , bogaz keçesi yada gözlüklerde, keçelerde problem varsa belki kurtarırsın pompanı .

[@poongkyelee2068]

It is really fascinating to see the inside of the gear pump!! Thanks for the video

[@MatthewMershon]

That was incredibly informative. I love your videos.

[@duramax78]

Thanks for another great video ave.

[@MohaMMaDiN55]

I love you man. I never seen such an explanation like this for gear pumps. neither in books.

[@tomthumb3085]

I can’t believe that it’s almost six years since I first watched this video. It’s still great to watch now. Thanks.

[@tomdaloon]

Another great video Ave! Learned a lot, thanks!

[@dukeman7595]

I learned more in 10 minutes regarding the workings of a hydraulic pump/motor than I ever did watching KZbin videos.

[@dirtydish6642]

Put my 48 Ford 8N into a tree stump, cracking my loader pump case earlier this year. Had to self learn everything you just showed. This filled in some lingering gaps of knowledge from that day.

[@nickledimez4012]

Very Good man! I’ve learned a lot in so little time! Thank you.

[@a__duck]

This is awesome , im taking a hydraulic design course right now so this is at a perfect time!

[@promenacegaming5402]

I just had to rebuild one of these on my PTO for my wrecker, and damn. This knowledge is great.

[@pauldavidson6321]

The ISO code on the pump body is stamped "P " for pump or "M" for motor , Motors also usually have a case drain port.it would appear someone has swapped the rotation group to change direction. You have a pump in this clip as indicated by the seals on the thrust plates ,a motor is bidirectional and the thrust seals seals are figure 8 shaped .

[@dukeman7595]

You have a great deal of knowledge telling the difference between the two. You should have a KZbin channel.

[@pauldavidson6321]

@@dukeman7595 I run a hydraulic repair business.

[@Pyronics]

That was awesome! Actually great info and fun while we are at it! Love it!

[@mysinglefriend]

Great video, and great style. 10/10! Thanks for making it humorous too.

[@lourdesamykupusamy4314]

I appreciate your clear explanation and good reasoning.you are professional. Thankyou for sharing without holding any secrets.

[@evansveilleux5168]

Very clear good views,explanation,and comprehensive language;as much as vocabulary,u can tell the speaker knows what’s an hydraulic component

[@marklowther2133]

The cut out pieces on the gear side of the bearing holder only allow oil to escape back out into the side of the pump that it came from. Because the groves don't break into where the bearings are. The groves on top do look like they allow the high pressure oil into the bearings. I think this makes sense because if the oil was flowing in and out of the bearings it would not be at as high a pressure. Also I love your channel, and I wish I had lecturers like you at uni.

[@MrBanzoid]

Thanks for the explanation. Brilliant.

[@garym8348]

Thanks man. Very in-fkn-formative. I had to replace the oil pump in my car about 20 years ago and for whatever reason I thought about gear pumps and watched your vid. Great job, good info.. Thanks again.

[@HennerZeller]

I never really thought about the details of a gear pump and falsely assumed that the oil goes through the middle part, but had been wondering how it would do that as the cavity is pretty small there. Doh. That the oil goes _around_ the outer diameter makes much more sense. #TIL. Your vijeos are a source of interesting information. Skookum as frick. Thanks!

[@tomcummings3471]

never thought about it until seconds before he was explaining it, but I too assumed the flow would go through the middle. which makes absolutely no sense in retrospect

[@MIGASHOORAY]

N

[@TimpBizkit]

I always imagined the closing in teeth would pressurise the oil (although the oil doesn't change in volume very much at all unlike with compressed air) with some leakage but yes going around the outside makes more sense.

[@hamppid1alfathponphydrliqe60]

[@miguelash886]

I made the same assumption

[@MG-it9mw]

Very education and accurate. This helped me to understand the K46AC transmission. Thanks

[@jhjbeckett1]

Sir, you have a way of breaking down high end knowledge to my level. Also, I can't stop saying chooch or skookum. Thanks!

[@anger806]

I am a mechanic for a company which specializes in truck mounted material handling loaders (primarily logs) ran completely by a gear pump mounted to an eaton pto on the underside of the truck transmission and driven by the input shaft of the transmission, typically when we see symptoms of a tired pump we only replace pumps, not disassemble and repair. This vidjayo defintely helped me understand a little more of the witchcraft that goes on inside these pumps

[@ryanbarbolt3691]

I've been taking things apart since I was 5, and I gotta say I love your channel, even if you are Canadiene. Keep it up

[@rogerkerr5745]

Great vid, would love to see more. ie spool valves, proportional control etc etc

[@crazytrutas]

Great, always learning something with your vids.

[@ALegitimateYoutuber]

After hearing you talking about pressure and flow, I wish you would do a few videos just on the basics. Kinda like what you would see in those old education film from like the 40's. Because without a doubt you're knowledgeable enough to get the info right, and I feel you would easily be able to put it all in layman terms.

[@MrOner07]

I love this channel...always make great videos!

[@jimnnobody]

Best explanation ever. Thank you.

well thanks again Hoser, beauty lesson. very entertaining way of educating.

[@moeshouse575]

Moe7404. i worked industrial hydraulics for 20 years. now retired. that demo was the best that subject could EVER be done. the part about pump or motor is a point that even a lot of people that work on them dont even understand

[@neilcarrie3396]

I to work in the hydraulics industry and it does catch a lot of people out. What he stripped down was actually a pump tho because of the 2 different sized ports and the kidney plate seal only sealing off the high pressure side. Some pumps like commercial brand actually run a full seal around the shaft like a motor has but the ports are the give away.

[@mattzze98]

Ist a one directon motor wich needs the sealing only on the higpressure side an a lekage flow from the bearings spots to the Tank side The actuator is labeld as a Motor also Greetings from germany

[@keithcarpentersr.4353]

Moe Shouse I have an old backhoe and not really any power or force when I’m using the backhoe part. Would it be a bad pump?

[@soaringkhaled]

Wow.. Thank you very much for this informative video ... it helped me understand so many things, and now I can reassemble my micro gear pump for the 1/16 Hydraulic wheeled loader :) ... Awesome Video !!

[@roscoepcoletrain2716]

thank you so much for your help, u taught me so much I needed to know if a pump could run either way all I have to do is flip the gears wow thanks again

[@sv55492]

Great video! Could you possibly do a video of the internal workings of a hydraulic pump/motor and how it transitions between the two functions? Thanks!

[@DoRC]

Very interesting. From the automotive mechanic side is always throught it squeezed through the middle. This makes more sense now that i see you explain it.

[@crazyDIYguy]

Such a good video, so much simple and good information I immediately paused and took notes in my notepad app.😎👍💯

Think you should find some vajayos that’s apply to your needs friend

[@jeremyjames83]

Love you vids man..! Keep up the good work

[@ta420nk5]

Great video, your ability to explain relatively complex workings is second to none. I was going to ask your option on a brand of tool the other day and bam there it was, what do you think about porter cable?

[@WatchWesWork]

I love how you go into detail on how to verify that it's a metric bolt and then you wail on it with an 11/16 wrench. You can't script gold like that.
