Centrifugal Pumps

- Clarification: Cavitation bubbles are NOT air bubbles, they are bubbles of vaporized process liquid (eg steam if the liquid is water). Entrained air (ie air bubbles which are already present in, or are injected into, the process stream) can actually be helpful in very small amounts (less than 1%), because they mitigate the effects of the more troublesome cavitation bubbles. But larger amounts of entrained air (or any kind of gas) can negatively affect pump performance and reliability in a number of ways, including inefficiency, vibration and air pockets which cause dry-running of the seals.

Hi, Adam, I´ve been a teacher for 40 years. I´ve never seen such a flawless class. Congrats!!!!
"Pressure Energy" really?
As someone who has serviced and sold pumps for over a decade, I can safely say that not only did you get all the science and physics of pump design correct, it's also the most informative centrifugal pump video I've ever seen on RUclips or any other platform. Well done!
This video is the best introduction to centrifugal pumps I have found. I teach process technology and direct all my students to this video for their introduction to centrifugal pumps. Well done!
Your introduction to the mechanical equipment is very clear, precise and great. Thank you so much!
Well done. I learned how to operate these type of pumps that are used in firefighting apparatus many years ago. This is the best presentation of centrifugal pumps I ever seen.
You have done a very nice job explaining the basic hydraulic principles in pumping.
Great video on centrifugal pumps. Anyone in the fire service would benefit watching your presentation, since the most common pump used in the fire service is the centrifugal pump.
Excellent video. One of the most clear explanations I've seen... This is what makes RUclips worth watching.
I love this. You make the video extremely engaging with the animations. I feel like I learnt something at the end of it, unlike what my engineering college teacher taught me in my bachelors
I wish I knew this channel back when I was studying Mechanical Engineering.
Same
Hhhhhhhh me two ،، but It's not too late to learn 😁
LOL...how old are you...didnt you know Al Gore recently invented the internet...so there was probably no RUclips.....just kidding
Thought so too
I'm not even studying mechanical engineering... I've just found myself building a pump from scratch... Realized an axial pump isn't what was most suitable, and a centrifugal pump is... designing 3d printing jet drives designed to be used on a kayak is fun... Untill you need specifics on how a centrifugal pump is actually designed and why
i'm late to discover this but this is amazing. not only is the language easy to comprehend, the animations help a great deal in helping to visualise what textbooks try to convey. thank you so much!
This was an amazing video. I spent many hours reading through a half-dozen websites trying to understand centrifugal pumps and volutes. You made it crystal clear. Excellent video editing too. Would you also tackle vortexes too?
Your work here is simply superb. Very clear, straightforward and accessible to anyone with sufficient IQ. Well done. I think you should have at minimum, a million subscribers!
Holy nuts I've never subbed so fast. Great commentary, scripting, hosting, diagrams, editing.... How am I just finding this channel now?!?
you've helped me so much over the last 2 years of school. Just wanted to say thank you.
this was honestly a turning point for me understanding the centrifugal pump. you are the man gracias
Ah man, you're awesome sir. This is the kind of teacher i want to have in my most regrettable curriculum -Mechanical Engineering.
Aman Kumar the explanation was a very gross simplification of fluid mechanics. There’s A LOT more to this than what he explained.
@@ElZamo92 think he accomplished a lot in a 8:25 min video lol
But hopefully we won't get any teachers like him in our class😅
I work as a shipping receiving manager for a large pump distributor, I'm hoping to move into the mechanical side of our business and this definitely gives me a better idea of how they work please keep making content
These vids are great. I hope you keep at it! It'd be interesting to see a vid contrasting pumps and blowers.
he's using subversive nazi propaganda techniques that will program your subconscious mind: 3:35
Working with these on a daily basis now, thanks for sharing. Helps me understand just a little bit more why the pump won't grab the oil sometimes.
By far the best descriptions & explanation of these pumps Ive ever heard.
very informative video. you have mentioned every single important aspect of centrifugal pumps and nothing has been missed
Thank you, man. You are better than my teacher at the university.
I learned a lot. Thanks. I remember all this from Physics. Its nice to see someone explain it like this.
OMG!!! you are the best!!! Loved the way you showed everything. God bless you! And shame on 124 dislikers.
I just found this channel almost at the end of 2019. I see that the last upload was like 9 or 10 months ago. I still subbed and hit the bell in the hopes that I'll be able to consume more of your content. It's very well done and I enjoy it
... and we are two :)
one more :)
@@okarakoo And another
And another :-)
Lucky 7? 👍😁
One of the best explained videos of centrifugal pumps i have ever seen.
I've never been interested in physical machinery until this. Thanks for the super-clear and super-engaging explanation! Keep it up ;)
Excellent presentations! My new word of the day: "Cutwater". I never realized there was a term for that part of the volute/casing.
Shame you get so few views. Very helpful, learned a lot! Will recommend to friends.
2 years later => half a million views.
I think there is no shame anymore :)
Hi Adam. You were in my search results for 'pressure control valves' ! haha
This is the best video I have seen on the subject, Thank you for making and Please make more!
I saw this demonstration 30 years ago. Excellent video.
Very nice video! Hope you will make more videos like this.
- Regards a Marine Engineer Student.
Great job! Congratulations.
Wow spot on, your channel is going to explode!!! 2,781 currently at this date!!
Such superb animation coupled with clear easy to understand explanation, great job Adam.
Your'e a live saver Adam! Needed a crash course and you gave me one.
Very informative. As a mechanical engineer, this presentation was spot-on.
My years in the Navy we worked on these pumps all over the ship. Firemain, Chill Water, List Control, even air ventilation where a non sparking unit was needed or for high air pressure like the Buffalo Forge Centrifugal fans.
Wooow hat off for you man. The way you explained this is so easy and so detailed. I have a project on Centrifugal pumps and am certain about a 100%
The crack sound from his hand is addictive. Thanks for the videos. Keep producing videos.
This video is very educative and it's helping to know and understand more about C.pumps.
Good learning from your video. I am going to watch more of your videos for better understanding and learning. Keep posting Adam!
Duuude, I wish you were a teacher of mine hahah my class of unit operations I wasn't really fun, but your videos make the subject a lot more interesting
Good, many on here are dumbed down, yours gives just the right amount of good information.
The quality of education of your video is very good I wonder how it's free.
Please continue uploading videos! Your work is great, and most enjoyable! :)
I may have found a new favourite. Very interesting and well explained videos. Thanks.
I studied cavitation for nearly a year; man dat stuff if the expansion of the Universe for layman!
Surprised/not surprised you didn’t bring it up. 👍🏻😂🇦🇺🤜🏼🤛🏼🍀
Super well explained and demonstrated. Great job!
Hi, You are a great teacher because it is clear and contain all information in a short video.Great
First video on pumps I've seen with the proper pronunciation of "centrifugal"
Thank you for this video. Looking forward for some other videos about valves compressors and gas turbines
Speaking of the flow direction based on the centrifugal pump's blades curvature, yes, you should tell in which direction the pump will have it's best efficiency for moving your fluid, hence from the eye center towards the blades tips, but it doesn't mean it won't reverse the flow if you rotate the rotor in opposite direction, but cavitation may occur much sooner (at some lower rpm and outlet pressures).
This is great for my process major. Thank you!
Really great video! Very well explained. Thanks so much for posting.
Please continue making the videos. You ate awesome, the way you explain is the best and your video edits are too good.
Pumps 101. Awesome. I understand that changing the impeller by just a little controls volume and preassure immensely. Most trash pumps do high volumes with low pressures. Fire pumps do higher pressures with lower volumes. Dredge pumps for small gold dredges are somewhere in the middle. Pump design is tailored specifically for its specific use and hose size.
Excellent videos. Thank you, Adam!
VERY WELL EXPLAINED
GOOD TO WATCH FOR NEW AND SEASONED INDUSTRIAL MECHANICS
THANK YOU FOR THE VIDEO
I work on a ship, a marine engineer. These kinds of pump are very common on our system, we use it for sw systems.. This video is very very helpful for us! Thanks man!
No you ain't 😂
Adam, You should do a video on pump curves. Centrifugal and PD curves.
great job. A video on pump curves is a great ideaa
Perfect content. Please continue. Waiting one video of valves if possible. subbed.
Excellent content, very informative and easy to follow! Love it!
I really love the way you explain the subjects. Thank you so much 🙏
Great video! Thanks a lot! I wish you also showed and explained about the throttle bush
superb explanation on centrifugal pump
Great video and explanation! You deserve more views which you should get as your content is better known. I loved your command of English language too! Cheers!
You wouldn’t believe how you help me! Amazing work
Thank you!!! please make more videos about all the process equipment. very good presentation!
Great presentation! Very informative and educational. Good job thank you!
your videos are more than amazing.. please keep making them
Im looking to get into the O&G industry. Glad I stumbled across your videos.
Thank you for the great video. I have a question about the effect of temperature on the characteristics curve of the pump.
How does the characteris curve of a centrifugal pump change with the decrease in temperature provided that the pump power is constant.
A reference material to read would of great help.
Thank you
the Best explanation on centrifugal pumps... thanks bro
magnífica explicación Adam!! muchas gracias!! :) ojalá sigas haciendo muchos más para quienes estudiamos una carrera técnica o ingeniería. Could you explain how an air conditioning works? I can´t already understand how it changes hot air into cold. Saludos desde Veracruz, México.
Existen varios videos donde explican el ciclo de refrigeración
. Si te interesa te puedo recomendar uno
Good job. I loved this explanation.
Well made video. Explains nicely in a simple way
Pretty good thank you. Are their any formulas that would apply concerning impeller diameters, thickness and speeds that could be used to determine horsepower from resultant flow and pressure?
Best video on centrifugal pumps !
The videos on the pump are really awesome. Thank you so much, sir. Looking for a submersible pump but didn't find it. Can we get a video about submersible pump?
Very effective and informative!. Thank you from Nagaland. India
It pains me to hear people say it as "centrifikal" rather than 'centrifugal" as it is spelled.
Other than that, this is a fantastic series of videos. Great work
3:45 I included this part of your video in my video to explain why you need to have an emergency fund. Lol
This was amazing. Keep it up!
This is an outstanding video. You are an exceptional instructor.
Very good presentation for beginners, thanks.
I gotta say, I really enjoyed this video.
nice one adam i'am a pipe fitter and mechanical fitter thank's for additional knowledge, nice explanation bro. keep up the good work more vids. to come ☝️💪
This is a great straight forward video
Great work Adam
Awesome video, man! Pretty much how all automotive water pumps work!
bravo!! very well explained, very well illustrated too!!!
So nicely explained, Thank you
You have the best way of explanation bro.
certainly this video made my concept clear about this topic than any other videos on youtube.
Great video, i wish we had more teachers like you in college!
College is a scam.
thank you mate .. classic video
That was an awesome video, thanks!
