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.
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
Great explanation! Thank you. I never understood how a vacuum pump worked until now.
Wow! For a person like myself who knew nothing about a vacuum pump, this was extremely simple to grasp! Kudos!
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
This is by far one of the most explicated videos on vacuum pumps I have come across!!!
Refrigeration mechanic here well done! Used a vacuum pump for 15 yrs now and always wondered what the inside looked like!
You are the absolute best! These videos need to be shown in every classroom around the world
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.
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
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!
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.
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.
These videos are life savers! Please never stop doing them!
Excellent explanation showing clearly what is happening. 110/100 Thank you
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
I just wanted to see the vane compressor arrangement - so perfect level of detail for me. Super video.
Another very concise explanation for something that seemed complex
Keep up the great work
Thanks, Charles. Glad you enjoyed
As usual, your explanation coupled with great animation is an excellent and worthy teaching aid to all institutions of technical education.
Really enjoy both your videos and HVAC School videos! Awesome collaboration. Keep up the great work! Thank you
Glad to hear, Daniel. Thanks!
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.
Technical video made to understand it's principles, working conditions and usage in air-conditioning. Thanks.
I learned something new with vacuum pumps. very informative video.
This is the Best channel I've ever subscribed to!!!
Thank you!
I am a HVAC engineer you explained everything well
The ballon example in regards to the high side/low side pressure is a great analogy for explaining equalization. 👍
You made it look so simple, thanks a lot!
Very well explained, thank you.
Good work Paul. Could you please make a video of how marine and aircraft refrigeration systems work.
Super Nicely explained !! Thank you for such cool animation !
best video thanks for everything i'm from somalia
Great video, clear explanation, loved the animation!!!
Just what I looking for! ... thanks for made this kind of videos! :)
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.
WOW. this was very good. i finally understand this.
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 :(
Love the guy at 4:24 trying to wrap his head around this video.
Any chance you could take us through a high vacuum pump at some point, as a continuation onto this video?
Beautifully explained.
Perfect explanation. God bless you.
Give this man a Nobel prize 👍
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.
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....?
Is this process primarily for removing moisture, or can it also test the structural strength of the piping at the high operating pressures it will be subject to?
These illustrations are sick!
Great job, straight to the point!
Great video beautiful presentation and great information thanks.
Keep going keep going
Your videos are very useful to me
Thanks for the explanation
I have a doubt. How theblow pressure region and high pressure region gets separated. Please explain.
For a long time i’ve been wondering how A/C units work and now I know☺️
Perfect explanation
The pumps I've rebuilt at work don't use springs to push out the vanes. They're just thrown out by centrifugal force. They also all have more than two vanes, typically 6
Awesome as usual !
Thanks for the information!
could we use a reciprocating or rotory ac compressor to pull vaccum.2.what is the time required to pull vacuum in 1.5ton unit using single stage vacuum pump
Thanks for the knowledge sir....love from india
Thank you, did you check out our new Hindi channel? ruclips.net/channel/UCg4k338hz9U8jnD5SXPO5jQ
Thank you for good information.
I wish I found this channel sooner.
Engineering Mindset is my crack
Great explanation! Thank you very much.
I have a pump with weak suction. No visible oil leaking anywhere, but I can feel air leaking out of the side seams- either where the pump or compressor sections screw into the body. Is this potentially a bad gasket or something?
Very nicely explained brother 👍👍
Thanks for the great video. I'm just confused why the there is a lower pressure inside the inlet of the compression chamber ?
Really well explained! Thank you, Guys!
Thanks Paul!
非常に勉強になりました ありがとう。
SO beautiful explain sir
Well done explanation but now I have a headache from so much knowledge! Who thinks of these things? Incredible.
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🇩🇪
This was really interesting to know, thank you. Have anyone ever been told that the pumps were "pumping high-pressure vacuum" in the system? If it were not misleading, it would be hilarious.
Thank you this was very educational
Thank you for the video
Very well explained thanks
Wow every video is so good and details
I been using pumps on the daily. Pumping oil into barrels. It sux sometimes esp when you gotta change the impeller
Great topic, how about go deep in how the springs act as pushes the look up.
Would've been good if you explained the reason for a ballast.
Excellent video!
Sir, Can we use single air compressor pump with compressed air tank and vacuum tank simultaneously ?
so useful, thank you
More info on the direct hose connection would be great.
I use a Ritchie yellow jacket vacuum tree, and tie both high and low lines to it at the 1/2” fitting on the pump for faster low restriction flow.
That's why we collaborated with HVAC School so they show your how to connect and why and we explain how it works internally
@@EngineeringMindset hi
Can i use vacuum like a compressor for a small things?
Thank you
Thanks , I have problem I have rust water run in to Vacuum intel.I change Oil but It will have problem? How to do? I call at shop they don't know anything.
Good explanation except 4:29. Given the same type, a less inflated balloon always has higher pressure. If you connect less inflated balloon to a more inflated one, the smaller will always inflate the larger one. The same is true with soap bubbles.
very well explained
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.
Hi there. Where can I find a complete schematic diagram of a robin air vacuum pump? Thanks
Hi, can you please explain the vaccum pump operation in the confectionery manufacturing process?
Much appreciation .
One question: How is it only air reaching the compressor? Would an inlet from the system include the coolant?
Could you do a video on micron gauges?
Superb video Thks
Thanks Doood. Well done 👍🌹
Really cool, thank you.
You're welcome
One of the best!
Wonderful video! Thank you!!
Do you also have a video on how turbo molecular pump works?
Very good n supper useful tks mate
Good have a question can a system that sucks air and hold it then release it.
Let's say we have coloured air we calculate the volume and fill up a transparent glass then we reverse it making it colourless?
