What is wet Push up of Propeller?? Wet Fit and Dry Fit Push up methods|Ramesh S|RMETC videos.

[@strobe4565]

Thank You so much Sir. It feels criminal that such high quality educational material is available for free.

[@lakshmananmani4632]

Principles of propeller extraction explained in simple, easy to understand graphical representation. Kudos!

[@rmetcvideos]

Thank you sir

[@MrKemron]

Sir your explanations of rudders and propellers have be extremely crucial in my understanding of the intricate parts of these equipment. I I thank you whole heartedly for these videos. I wish you nothing but success in your endeavors.

[@shivanshu201991]

Sir pls make a video on propeller curve. No gud video is available online. It is very hard topic to understand but u make every topic look so easy. Please do the needful sir 🙏

thank you sir...looking for more videos

[@jitheshgopinathanpillai3121]

great vdeo sir

[@ejazkhan8534]

Good work ,

[@aruntdh]

fantastic video and thank you - just one comment sir. Radial expansion of the propeller boss due to high pressure oil injection is also one of the key reasons why the jacks will face a lower resistance during the wet push up.

[@rmetcvideos]

Yr point on expansion is correct but am wondering about the logic of lower resistance bcoz of that...had it been expansion due to heating..this logic is Ok...in this case the boss WANTS to shrink back...So the lowering of resistance is due to coefficient of friction..hope u agree

[@aravinthraj3341]

thanks for the video sir. after watching your video, there is no need for studying the concept. way of your explanation is very clear sir.

[@rmetcvideos]

So nice of you

[@ravindraudakumbura4219]

Very important sir

[@Mariner-y5c]

why is 1st blade of propeller and the main engine no. 1 unit is kept in tdc position, after re fitting the propeller on the tail shaft during dry dock.

[@vishnumohan9842]

Nice video sir

[@rahulbhatia3481]

Thank you sir. Plz make video on governor droop setting.

[@rmetcvideos]

Complicated topic , but will try.

[@sreekanthkunni2227]

very helpful

Thank you very much sir🙏

[@muhammadahsan3875]

Respected sir please make video on Manoeuvring system How reversing is possible in direct reversible engine Regards and thanks

[@kunalsharma6976]

Thanks Sir... Sir, if you could plz make video for thrust bearing... arrangement and clearance... measurement.

[@rmetcvideos]

As soon as possible

[@jithugeorge14]

Looking forward for the pilgrim nut method.👏🏼

[@rmetcvideos]

Coming soon!

[@akhileshshukla8313]

Sir, What is the Significance of 'At critical speed' mentioned in the tables...?

[@amiths04]

Sir while removing propeller boss using SKF method how much pressure should we exactly apply?

[@harishankar-sc1dz]

Why we are doing dry fit intially

[@vikashpandey7711]

Thanks a lot sir

[@srajankajle5470]

Sir please make video for stern tube , header tank importance , types of sealing.

[@rmetcvideos]

sure .in future

[@jamshadrafique1490]

Hello sir can you please tell me what is nominal torque ?

[@gcsreddyreddy2502]

Sir, nice explanation. how do we overcome bimetallic corrosion between propeller and shaft in case they are of two different materials?

[@rmetcvideos]

you see there are anodes in the aft..Prop and shaft are of two differenet materials

[@mayankmishra3379]

Nicely explained, thank you sir. Mayank Mishra (DMET 2010-14) batch.

[@jaimintandel7340]

I have question regarding main engine how we can measure crankcase pressure?

[@rmetcvideos]

I am not aware of us measuring crankcase pressure.

[@arvind2170]

So sir,The jacks are pushing the propeller boss after the jacks are set up upon the nut....so the threads of the nut are helping in pushing of the propeller boss?

[@rmetcvideos]

yes

[@soorajnp4865]

Thanks sir

[@vijay.a4499]

thank you sir, I have a doubt whether pilgrim nut method is a dry push up method?

[@rmetcvideos]

It is a DRY push Up..

[@vijaymarine8088]

@@rmetcvideos thank you so much sir your videos are really helpful for me for preparing for my exams.

[@deepakshanmughan7928]

Thank you sir... One doubt sir can we do the skf method with wet push up alone? Why do we need to do the dry push up first and then go for the wet push up?

[@rmetcvideos]

Very good question.....if we do not do the dry push up,the oil will simply leak out and you cannot even be started with the wet push up..so for the pressure to build up in the first place you need a certain amount of interference fit

[@deepakshanmughan7928]

@@rmetcvideos thank you very much sir... You are an integral part of my exam preparation and im learning a lot from the channel... 😊

[@ranjithkkrishnaa]

@@rmetcvideos Sir, in addition to the above said reason, is it correct to say that Dry Push up first in order to know whether the surface roughness of shaft is within limits & also to get the initial push up distance?

[@anupammishra9162]

thank you sir

[@mohammadaslam9100]

Hello sir one Q plz answer sir After coming out from drydock your SFOC increase what is the reason sir?

[@rmetcvideos]

:-) there is no such rule..If it is happening.. depends on what you did in drydock. Maybe you replaces all piston rings and Running In his not complete. Maybe you changed a lot of steel and the ship is heavier.. Maybe you fitted new equipments which added to weight and increase the windage..Many possibilities...

[@mohammadaslam9100]

@@rmetcvideos k sir if asked by surveyour we can give this answer because this is asked in mmd exam

[@rmetcvideos]

these are the general possibilities. But if surveyor has something specific in mind based on his experience then we need to check up with the guys who have gone to him earlier 😂

[@mohammadaslam9100]

🙏sir clear my class 2 oral today and done with exams ❤️your video explanation are very helpful sir 👍

[@mountaintosea7843]

How we explain tjis push up chart

[@rmetcvideos]

Different specifics as per makers..but conceptually ...a particular distance after the pressure has developed on the push up jack..this is the dry push up..then with the injection oil another definite amount of travel to reach the final push up distanve6

[@physicsabhishek]

Sir you didn't mention to purge the lines first. MMD surveyors look out for such intricate details to fail someone in MEO exams

[@rmetcvideos]

:-).You are correct.You should start with --wear a helmet and Ear muff safety Shoes etc...Ha Ha..All those points are for you to add if you are going for Orals..Ha Ha Thank God I am Not sitting for ORALS...

[@physicsabhishek]

@@rmetcvideos No sir it is our bad luck that you are not sitting for orals. Atleast you would have considered these points by default and not fail the poor candidate just because he didn't mentioned these words. That's the ugly reality 😞.
