Absolutely LOVE this channel and videos. So clear and easy to understand. Graphics are not so helpful and it is all at a good pace. Thank you sooooo much!! Coffee on route :)
Mircea Believe the N would work just fine at the step down transformer WITHOUT being ALSO grounded. Understand your confusion. The N switches polarity in reference to the TWO ends of the secondary coil. Being both positive and neutral at the same time with reference to the stated two ends.
Amazing visualisations on your channel! Hardest part about understanding something is to visualise it. Should have had videos like this when I was in school! Keep up the good work!
I really struggle understanding the principles you cover in the usual text books. The videos you produce REALLY help me understand with the brilliant animations and simple way of explaining complex ideas. So thank you. You should produce some simple DIY projects for physical experience with the principles you explain so well!
What an wonderful explanation with clear cut diagrams to understand everything you want to know about pumps ! I liked the way how you explained the function of Capacitor in pump . Thanks 🙏
Literally days ago I was explaining how difficult it is to find quality learning resources for industrial engineering. So glad I've found this channel, just wish I knew about it during my apprenticeship haha!
Big fan of your work. I am a marine engineer(Mechanical) and would like you to request to make a video on grounding check in an LCP. One of the main reason behind failures onboard
I learned more about life from this video then I did my entire childhood. I should probably go write a book about my experience with this 12 minute video now and then retire.... Good job! Was very informative.
Fantastic video. IN North American hot water heating systems (radiator) we usually have the circulation pump on the return side and located at the boiler. Thank you.
Please do an updated video for the AC motors! Would really need that! Your videos are great, not only for stuying, but also if you're just interested in how electrical stuff is working!
It'd be great if you could do a video on hydronic systems design. Like designing hot water piping systems for serving radiators for example. Things like how to maintain pressure balance using control valves, reverse-return systems, when to use VFD's and why, 1-pipe & 2-pipe layouts, etc. Love your videos. Keep up the good work.
Good suggestion, I'll add it to the list. Have you seen these videos, they might be helpful Boiler systems: th-cam.com/video/lDeuIQ4VeWk/w-d-xo.html Pressure control vlaves: th-cam.com/video/nAM5xU_KfzU/w-d-xo.html
majority of times, you can tell whether its an inlet or outlet by reading the pressure of the gauzes that usually comes with the pumps. An inlet pressure would be lower than that of the outlet. It works very similarly to that of a compressor if you will. The centrifugal force creates a higher pressure and higher temperature of flow with a liquid or vapor on its oulet movement.
Excellent video. 1 stupid question. If electricity changes direction than why fans, motors rotate in 1 direction? They should also change their direction as per frequency... Thanks.
very useful video , the question i have is : in a heating hvac system, where does the circulating pump installed ? isn't on return water line or supply water line that feeds the coil from the water heater
People, if you want warm water coming out fast at the faucet, simply make the loop without installing the pump. Pump is not necessary at all. Once the full loop is made in the warm water line, warm water will circulate through the warm water pipe by convection effect where hot water expands in the heater and forces the water to move through the loop to colder region and back into the heater and continue the cycle. I had a water pump installed but failed and I took it out and bypassed it and I still get nice hot water very quickly better than ever before with no headache to deal with failing pump or timer. Pump and timer are expensive and difficult to maintain and absolutely not needed in most residential use. If you do not believe me, try first before you take the trouble of installing one.
Do you mean disconnect the capacitor? It could be just a start capacitor that only creates an initial starting magnetic field, once the motor is up to speed it is disconnected and the motor can sustain rotation. But it will not be able to start without this.
I've always heard that these were wet rotor type pumps, however you didn't illustrate that, so i was curious if the water also cooled the bearings or not. But nonetheless, great video!
good evening can I ask why small pumps (10/15 m3 / h) with high efficiency have extremely small impellers and a high number of rotations? in this way do not risk cavitation? thank you boss
Thank u so Much for the video! May i ask besides working with concealed water tank, can the pump still pulling the water in (thru inlet) from a (top opening) small plastic water container and pump out water from the outlet in high pressure please? Thank u in advance : )
We have 2 tankless gas heaters and a hot water pipe that returns to the heaters, we can insert a pump in the circuit but since these heaters start working when a tap is turned on, the first time in the day the hot water is used it will not give immediate hot watter. How can we set it up so we have hot water immediately the first time ?
If the starting capacitor was siized incorrectly what would happen? I guess if the cap was too small it would be able to create the required phase shift? What if it was too large?
What is the need for the can between the rotor, unless that means that the rotor can get damp but the stator cannot. I have 2 of these pumps on my hot water heating system. The Bell and Goossett pump is one its last legs and will need to be replaced for this next heating system.
Goodnight. I live in Portugal. And I have a grudfos 3x400v three-phase circulation pump motor that was 3-speed. it says on the plate 420w 0.82A. 530w 0.94A. 720w 1.30A. It burned out due to a lack of phase, it has a board that has 12 terminals and only 3m 3 of line 1, 2 and 3 transform it, as I didn't care about the speed. I asked to try to rewind at maximum speed and leave 6 wires that I connect star or triangle because here 2 phases of 400v. Since I connected in star I measured the consumption in the tweezers each phase is giving me 0.4A and it almost does not turn. In a triangle it was 0.6 and it already has a bigger spin. But nothing compared to how it was before it broke down. did something go wrong when rewinding? how does the speeds work in the 3 phase system? Since now the return
If I were to install a log burner with a back boiler and connect it up with the central heating system, which has a combi boiler, but the pumps would operate in the same direction, what would happen to the pump in the combi boiler if it wasnt operating? Would the water pass through the non operating pump? Break/damage the pump? Or not pass through the pump as it will be passing through the radiators and then back to the log burner. And what if the boiler valve was open asking for hot water, what would happen with the water circulation then?
If the pumps in the central heating system and the combi boiler are operating in the same direction and the pump in the combi boiler is not operating, then the water would still be able to flow through the central heating system via the log burner back boiler pump. This would not cause any damage to the pump in the combi boiler. If the boiler valve was open, asking for hot water, the water circulation in the central heating system would depend on the configuration of the system. If the boiler valve is set up to divert water to the hot water taps, then the water would bypass the central heating system altogether and flow directly to the taps. If the boiler valve is set up to heat both the hot water and the central heating, then the water would circulate through the central heating system and the hot water cylinder in the combi boiler, with the log burner back boiler also contributing heat to the water in the cylinder.
No such thing as centrifugal forces. It’s centripetal force. The centrifugal movement you observe is a lack of centripetal force which means it cannot accelerate inwards to remain static due to the linear force imparted into it.

I learned a while ago that if you set the pump backwards, you get to do the job all over again.
Lol
Lmao
That's why arrows are CLEARLY imprinted on the casing to indicate direction of water flow. Do you think they put those arrows on the case as a joke?
oh no 💀
10 years after i completed my engineering, i now know the actual usage of a capacitor. THANK YOU!

But I have a question that when I disconnect the motor after it starts it just keeps going on normally until switched off.
Do you mean disconnect the capacitor? It could be just a start capacitor that only creates an initial starting magnetic field, once the motor is up to speed it is disconnected and the motor can sustain rotation. But it will not be able to start without this.
Hi, thank for the informative videos.
We are using a circulating pump also in fire fighting water tank, what is exactly the purpose of it?

Do these work for cooling water as well?
I've always heard that these were wet rotor type pumps, however you didn't illustrate that, so i was curious if the water also cooled the bearings or not. But nonetheless, great video!
The bearings maybe permanently oiled. I see those in air conditioning motors.
Will the pump turn at all if it has a bad capacitor?

Prevent water from reaching the electrical coils.

All pumps of this type have to be installed sideways/horizontal!if not it wont last too long.
Oh yeah yeah
No pluggo bubble. 😥
So does the pump remains on
Depends what you're using it for. It can and usually does turn off for perhaps at night when there's no demand.
Duwayne Kelly-james Home heating system the circulation system pump only
comes on when the heat(boiler) is actually on.
Is it weird if i found it really mind boggling how the diagrams go right to left instead of left to right ...
No such thing as centrifugal forces. It’s centripetal force. The centrifugal movement you observe is a lack of centripetal force which means it cannot accelerate inwards to remain static due to the linear force imparted into it.
I knew someone wouldn't be able to resist commenting this 😂
The Engineering Mindset but if you knew it then why not use the correct terminology? It’s been this way for at least 25 years.
@@altypeRR Maybe because except for engineering students, no one has heard of centripetal force?
