Good Day. I was wondering if you could help explain how to convert a 3phase alternator to single phase.
Because I have 2 units of 5kv 3phase diesel gensets but most of my equipments runs on single phase. Therefore each phase couldn't take up much load.
An educational video on the basics of alternators for gensets running at various RPM , number of poles, frequencies and it's associated pros and cons would be a great addition to your channel. Thank you.
Can you explain switch gear and ring main units ? Struggling understanding atm and supposed to be working in substations soon.
How does car engine work pls
2@@eugenewong9101 ³ thank
I HAVE LEARNT SO MUCH FROM YOU AND WOULD HAPPILY BUY YOU A COFFEE AND A COUPLE OF BEERS!
Incredible video Paul. Masterfully explained, making the complex simple like always. Well Done.
My other teacher let's gooo!!!
I struggled many years to understand this, now i finally did understand it. Thank you so much.
Great explanation! Thank you. I never understood how a vacuum pump worked until now.
Simply Fantastic. I am using a vacuum pump since 1978 it is only today-now that i came to know exactly how a vacuum pump works. How an agelong ignorance is removed within 10 minutes with the help of modern techno presentation. Thank you.
Glad we could help you out
Love all of your content, simply explained and this is what I am currently working at México, thanks for all the info, gonna buy some merch or be a Patreon.
As someone who is studying this right now to become a HVAC guy, thank you so much for explaining this is in a way that made is it simple to understand.
Edit: grammar before morning coffee good is not
This is by far one of the most explicated videos on vacuum pumps I have come across!!!
Thank you this video has given me a much deeper understanding of the vac pump. 1 was wondering the other week about the difference between the 1 and 2 stage pumps.
👍 thank you question answered
Wow! For a person like myself who knew nothing about a vacuum pump, this was extremely simple to grasp! Kudos!
Another very concise explanation for something that seemed complex
Keep up the great work
Thanks, Charles. Glad you enjoyed
These videos are life savers! Please never stop doing them!
Really enjoy both your videos and HVAC School videos! Awesome collaboration. Keep up the great work! Thank you
Glad to hear, Daniel. Thanks!
Thirty years ago, for testing OEM air cond pipes and hoses, our engineering laboratory used a helium leak detector (small mass spectrometer optimised for helium) to assess the joints. It used two vacuum pumps plus a diffusion pump.
I just wanted to see the vane compressor arrangement - so perfect level of detail for me. Super video.
Excellent explanation showing clearly what is happening. 110/100 Thank you
You are the absolute best! These videos need to be shown in every classroom around the world
Very well explained, thank you.
非常に勉強になりました ありがとう。
Wonderful video! Thank you!!
This is the Best channel I've ever subscribed to!!!
Thank you!
As usual, your explanation coupled with great animation is an excellent and worthy teaching aid to all institutions of technical education.
You made it look so simple, thanks a lot!
That's so cool!! I have been binge watching your videos after I discovered this page several weeks ago now. I saw the HVAC school and after a few classes Brian mentioned he teamed up with you for this and now I am back here watching clips
Technical video made to understand it's principles, working conditions and usage in air-conditioning. Thanks.
Super Nicely explained !! Thank you for such cool animation !
Superb video Thks
WOW. this was very good. i finally understand this.
Great video, clear explanation, loved the animation!!!
Refrigeration mechanic here well done! Used a vacuum pump for 15 yrs now and always wondered what the inside looked like!
I just felt the need to research this and i have to say you are an incredible science communicator. I didn't have to pause at any point and understood everything you said. Maybe i am just dumb as hell but with physics videos this is almost never the case.
Very well made!
I learned something new with vacuum pumps. very informative video.
Thanks for the information!
best video thanks for everything i'm from somalia
Beautifully explained.
Just what I looking for! ... thanks for made this kind of videos! :)
Perfect explanation. God bless you.
Great explanation! Thank you very much.
Great job, straight to the point!
Awesome as usual !
Perfect explanation
Really well explained! Thank you, Guys!
Thank you for good information.
Great video beautiful presentation and great information thanks.
They are also used in the Dairy industry to supply vacuum for the milking units. They are quite large. There are usually at least two vacuum pumps connected to a parlor. If one goes down the other one is used, or they are both used in conjunction to help take the load off of one unit. If the vacuum pump goes down the milking facility cannot function so it's normal to oversize the pumps so that one pump can run the system itself, albeit barely, or have a backup pump just in case. A small dairy farm (~50-100 milking head) will have pumps that are about 1' wide and 2' long mounted with a large ballast tank. A larger farm (~500 - 2000 milking head) will have pumps the size of engine blocks. This video was helpful as I have worked around these things my whole life and always wondered how they actually created vacuum.
The ballon example in regards to the high side/low side pressure is a great analogy for explaining equalization. 👍
Thank you for the video
Thanks Paul!
Wow. This is excellent. The dual units is a trip. So would adding a third increase force linearly?
Hint: Not linearly, but logrithmically, approaching 0 at n = infinity.
Nice touch adding the tip about heating the coil to extract more of the water.
so useful, thank you
These illustrations are sick!
SO beautiful explain sir
Thank you this was very educational
Really cool, thank you.
You're welcome
Thanks for the knowledge sir....love from india
Thank you, did you check out our new Hindi channel? th-cam.com/channels/g4k338hz9U8jnD5SXPO5jQ.html
Very well explained thanks
Excellent video!
Keep going keep going
Your videos are very useful to me
thank you awesome information!
Much appreciation .
Good work Paul. Could you please make a video of how marine and aircraft refrigeration systems work.
Very good n supper useful tks mate
Very nicely explained brother 👍👍
One of the best!
Wow every video is so good and details
Love the guy at 4:24 trying to wrap his head around this video.
Interesting information thanks
very well explained
excellent explained.
Good explanation... super
good show
Thanks Doood. Well done 👍🌹
Very useful information
Nice video. Now i know how it work. I will make a vacuum pump using an old hydraulic pump and i post it on my. Next video so you will see it. Thank you so much
You can also use a 120 volts refrigerator compressor.
Give this man a Nobel prize 👍
I am a HVAC engineer you explained everything well
Thank you soo much
Thank you so much
Good information
Thanks!! regards from Chile
What a good video!
Nice video. Good job my friend.
For a long time i’ve been wondering how A/C units work and now I know☺️
Wow good video
Fantastic
Any chance you could take us through a high vacuum pump at some point, as a continuation onto this video?
Quite interesting
If you hook identical balloons together like that the smaller one is actually higher in pressure due to more elastic material per unit surface area.
That's a very interesting point, I like it
Thank you for saving me from typing this on my phone.
@ axelasdf And what you gone doo with the much greater surface from the bigger balloon? It’s just my question. Greetings from Belgium 🇧🇪. Peace ✌️
@@gunnarallgottsmann as the balloon gets bigger it's surface grows but the Material gets thinner. Therefore the tension gets less. Because the bigger balloon has less tension it's pressure is lower than the pressure of the little one and air flows from the little balloon to the big balloon. To experience this yourself just blow up a balloon. At first it's hard to produce the pressure with your lungs but at a certain point it reverses and it's easier to blow air into it the bigger the balloon gets.
Hope that answers your question.
Greetings from Germany🇩🇪
I wish I found this channel sooner.
Engineering Mindset is my crack
Vacuum pumps are also used extensively in the semiconductor manufacturing industry. Everything from rotary vane pumps to turbo pumps, to rotary blowers, to ion pumps, to cryogenic pumps, and everything in between.
Hmmm when you will release the video about diesel gen alternator? Love ya' paul keep it up!
Check out how car alternators generate electricity here: th-cam.com/video/jdSKlg80DjU/w-d-xo.html
This Jan 2021 I'm gonna go for HVAC so let's prepare from being too empty shall we,nice vid man!After reading at some comment, I realised I'm a slow learner :(
great video. has anyone tried to connect two two-staged vacuumpumps in series? if there's a reed valve it should help to prevent an overcompression and might improve the vacuumpower....?
I have a vacuum pump, but never knew the mechanics of it. Now I know.
Incidentally, it is the same mechanics that are in my hand-cranked fuel transfer pump, with the inlet being the tube on the bottom that goes into the bulk tank/drum, and the outlet being the spout on top of the pump. These pumps are nice because they are self-priming and reversible.
Special thanks
Very beautifuly explained
Physics explaining bernoli's theorm
