Queensway Mersey Tunnel fan starting up

[@JBF-GST-Tanda]

The sliding gate really deserves a badass loud deep beefy military-base-ish buzzer alarm.

[@benberding]

I’m a fan of the theatrical startup! Curtains open on a lonely fan. Dance starts, slowly building tension. Video cut short right before final climax! What a performance! 👏🏻

[@prestonburton8504]

ahhh, but don't forget the 'reluctance' - thats the 'eeeck' of the massive bearing not wanting to move right at the beginning of rotation! i'm thinking Vincent price!

I think it blows

[@Rocketman88002]

Yes, so much fanfare over the fan😂

[@m0cafet627]

Honestly they suck me right in.

[@marcchaffee7751]

I , am now a fan club member .

[@stevebot]

Fantastic! You couldn’t put a better spin on it.

[@HelloKittyFanMan]

Haww... HAWWWW!

FANtastic

[@marcchaffee7751]

This blows me away !

[@m0cafet627]

The softest starting motor that ever lived.

[@TheRobWay1]

Should just go across the line, dim the lights in the city !

[@nomusicrc]

Thank you for not adding music to this

[@Spartanvoss]

They should start their own Fan Club.

[@arcadegeek]

I feel robbed, the video should have gone on another 3 minutes

[@user-vp1sc7tt4m]

Yes, it was a real blow that it stopped when it did,

[@PeterEdin]

No reason it couldn't have continued. Prob deliberate. Thumbs down and unsubscribing.

[@chrisloder3363]

Mersey Tunnel fan ten hours for study

[@straight6petrol]

[@Nordic_Mechanic]

They painted it red so that when people get sucked it in, the splatters on the blades dont traumatize the other workers

[@Theengineer133]

Whats about the body part?

[@michaelnaretto3409]

Planning ahead. I like it..

[@BjarneLinetsky]

With huge machinery like this, electrical efficiency and power factor are very important. The driving motor probably rated at just enough power to keep the fan at rated RPM, hence the slow start-up.

[@prestonburton8504]

actually, i think i hear a VFD solid state type device - the original would have had reduced voltage starter (delta/wye) - you can hear the very high freq harmonics.

[@AtlasReburdened]

​@@prestonburton8504I'm certain that you're correct. I repair drives for a living and recognized the sound immediately.

[@prestonburton8504]

very cool! my company did the test rig for a navy pump supplier 4160 with a vfd - have you worked with higher voltages? thats the highest i have seen - i know they are now 13kv or so@@AtlasReburdened

[@prestonburton8504]

also -what's so cool? Hearing the massive bronze shaft bearings breaking 'stiction - when it first begins to turn and getting their lubrication film built back up -anything larger has a 'turning gear' that must keep the shaft turning slow -to keep this film intact@@AtlasReburdened

See you at the party, Richter!

[@lowaltitudepowersports4903]

Open your mind

[@bitterdrinker]

Magnificent piece of engineering. The rotor weighs several tonnes and is perfectly balanced.

[@9madness9]

Now that's a turbo for my truck

[@billymillions]

The boost is amazing, but the turbo lag on the spoolup time is terrible. Imagine the race though, the other guy sprints away from the line, and is less than 100' from the finish, and you come blacking by as the turbo finally gives you the boost, passing him at Mach 0.99! 😂

[@BGTech1]

Finally, a fan to cool my pc

[@RobertCraft-re5sf]

THAT IS INSANE!!!!! Thanks for sharing this. I'm a huge fan of giant industrial/municipal machinery.

[@kevinm.n.5158]

The intrusive thoughts are telling me to jump into it

Well you aren't jumping in it, so you're a normal guy. Everything is fine with you.

[@Atomic_Oven]

Those doors opening reminded me a lot of portal 2 for some reason.

[@Anomyzer24]

Its creepy being so giant

[@792slayer]

Big machinery really is. Especially if it's automated. It's just so impersonal.

[@HelloKittyFanMan]

Why is that so... "creepy"? How does it supposedly feel like some crazy creeper skulking around?

[@ponponpatapon9670]

@@HelloKittyFanMan i think everyone who isn't a pedant automatically understands OP means "creepy" as in the 'menacing' sense of the word.

[@HelloKittyFanMan]

@@ponponpatapon9670: 1. You can't know what other people would think until they tell you, because you're not a mind reader. 2. Nothing I asked him qualifies as so-called "pedantry." 3. You aren't still person I was even replying to, so you don't have to worry about it.

[@ucitymetalhead]

It really is for some reason.

[@wayneheigl5549]

would be great to see full speed

[@HelloKittyFanMan]

Yeah, that's what I thought, too! How come he cut it off right here? It took so long to speed up, too. Even as heavy as that motor shaft and those blades are, I'd think such a big strong motor wouldn't have such a soft start... even on a soft starter.

[@wayneheigl5549]

thinking about it now , every one is standing in that fan room and if they speeded up the fan it could suck every one in. ????????

[@mikeymcmikeface5599]

​@@HelloKittyFanManYeah. Lame!

[@HelloKittyFanMan]

Nahh, @@wayneheigl5549, this isn't like... some big jet engine fan. You'd have to be a lot closer to this one for that to happen.

[@gabrielv.4358]

Yes, but that culd be the full speed. Boring IK, but could be pushing insane amounts of air

[@wmsymms]

Definitely a scene from Half-Life.

[@HughieMunro]

Perfect place to throw a couple head crabs into

[@kilgarragh]

Would’ve said portal 2

[@HelloKittyFanMan]

Nah.

[@EarthCoreGames]

Aww you cut the video during the climax 🤨

[@craigmorris954]

I'd like to know what the point is of this sand in the first place

[@heroknaderi]

I assume if cranked on high it will blow tons of air

[@torque395]

Can you imagine the startup current that thing must draw, and for the length of time that it takes to start it? And it actually seems to be underpowered. A bigger motor would probably start it faster and with less energy use.

[@ZA-mb5di]

Why don't the blades have more of an angle to them? It seems like it wouldn't be very good the way it is

[@doct0rnic]

So does it go faster?

[@redsquirrelftw]

Now that's a big heavy metal fan! 🤙

[@Nintendo3D5]

What's the max speed of this thing?

[@poly_hexamethyl]

Why do they close those doors on it when it isn't running?

[@jeffhiner]

I'd imagine to keep the duct sealed, to keep air from blowing out or being drawn in. If you're running another fan somewhere a few miles away, you want the air to go the full length of the tunnel and not out earlier.

[@ayuse01]

Where is part 2?

[@moosanouman]

He's a big fan of ur video

[@kumarsanjeevasingh19]

Each blade are red😂

[@gavincurtis]

I didn’t know they had tours of Michael Moore’s bathroom fan. Amazing!

[@tonybochiano]

😂

[@daniellclary]

Fascinating that most mechanical machines involves the spinning motion.

[@claudevieaul1465]

"Pleased to finally meet you, I'm such a massive fan!!"

[@DeerbrookSouthernRR]

I don’t know why but there’s something really creepy about this. Like imagine you’re walking through a dark building and this big ass thing is at the end of the hallway running full speed

[@samk9729]

Turbines are into all sorts of music But they are huge heavy metal fans

[@julesviolin]

Only question from me...... Why aren't the hatches open 24hrs ?

[@AlessandroCussino]

The perfect fan for this summer. How much $ ?

[@ShortStuff0000]

Played in reverse would be a scene from Total Recall

[@davidpar2]

Those were some serious beef curtains

[@FEDERALSIGNALTECH]

What a big fan and it's very quiet operation but why does it spin so slowly and I thought it was a high RPM fan and what is fresh air intake?

[@Derek.Eva.Nightingale]

With any fan, the energy required (current in amperes if electrically driven) at the initiation of start up is to overcome the static inertia, plus friction in the drive system. As the machine rotational speed increases, the air it now begins to move creates resistance, which requires proportionally more energy, until the maximum rotational speed is approached, at which point the turning force, or torque, should remain constant. It is the opposite situation (regarding starting from standstill), to a motor driving, say, a compressor, lathe or other machine, which requires an initial high starting torque, or electrical current. BUT...... you already knew that, I would have thought....(!!)

[@ZA-mb5di]

Is this for a traffic tunnel?

[@klsar1]

What does this thing do? Fanning what?

[@flyguy5941]

Me when I fart,,,lol. Really it moves fresh air through the tunnel to help force out car and truck exhaust.

[@johngalt7382]

Is that the fan for the whitehouse diaper room?

[@huntspoint3442]

Yep Trump had it installed.

[@robertb.3651]

How fast does it spin 100rpm ????

[@danceswithbadgers4024]

I used to love things like this,but now im an extractor fan.

[@gabrielv.4358]

This is so scary. I have been 100m close to a water pusher ventilator that was 1 metre big I think, ang it was scary to hear that. I cant even imagine being close to that

[@lilclacla1610]

What kind of tunnel is it

[@nicksteele-u3u]

Road. Queensway tunnel, runs from Liverpool to Birkenhead.

[@kennymaclaurin3683]

The purpose of this is?

[@baileyjerman5573]

Air flow

[@karlreinke9653]

Where is this? Britain?

Liverpool.

[@micksalau]

Ant to think I tore myself away from watching paint dry for this.......

[@Ififitzisitz]

I've never heard of this before. What are the parameters?

[@felix30471]

very large

[@ckuethe]

I was not blown away by this video. Very disappointed by the description, it's just so much hot air.

[@MysticRixel]

This is taken directly from Portal 2

Hat-tip to the lads at Metro-Vick for a gearbox that will be around in 200 years. Still working. Probably still ramping up to operating speeds. (a VFD the size of a city bus...)

[@captainobvious9188]

Does it ever finish starting up?

[@akaikangaroo]

Rumor has it: this fan still hasn't gained the full speed

[@anthonytimpson4975]

this might effectively cool my 3090

[@r.scottmarsh5092]

Fantastic!

[@SkyChaserCom]

You can hear the whine of the VFD carrier - Imagine soft starting this before the VFD? Probably huge resistors to get it going initially.

[@pamthevan7340]

I bet National Grid notice when that gets turned on.

[@cloudy4872]

can this air cool an i9

[@berniestep]

pretty sure this entire process was designed by Derek Meddings!

It was a shame the video stopped before the motor was up to speed.
