This video systematically builds up a functional Hydraulic Circuit to operate a Rotary vane steering Gear.It will explain the concepts involved and the functional requirements of Any Steering Gear.#RMETCVideos ,#Rotaryvanesteeringgear,#MarineEngineeringTraining. Also please go thru the Rule Requirements in my previous videos • Steering gear for ship... and
• Steering gear for ship...
Sir your videos are sooo Intresting🤩👌..... nothing can be better then this 👌
So well explained 🤩🤩👌
Very nice explanation thank you so much sir
Started from one question to another, Great Sir because due to this we will not have that confusion that what is this and what is that, as you also know that these steering gear diagrams are very confusing due to their there symbols. Thankyou Sir.
Gmg sir saw all ur video
Thanx for sharing ur knowledge
Best regards
Thanks for explaining in details sir, which we most of us are not aware about.sir, keep sharing your knowledge.
As usual sir... Another excellent video... This channel has the best content for marine engineers explained in depth and concisely, with excellent animation. Thank you sir for the effort u r putting in and sharing your knowledge 👍🙏
Thank You Sir for the wonderful explanation.
Excellent video..All clear ❤️❤️❤️
As always, Excellent video sir.. Crystal clear explanation without missing a thing.
Glad it was helpful!
Sir one of the best explanation about rotary vane.... Understood how pilot operated chexk valve play an important role in the motion of rudder.... Thank you very much sir❤
Nicely explained. ..sir
Excellent one sir..,, hope u will come soon with 4 ram ship circuit🙏
sure.. will do a few more on steering gear. Hope guys dont get bored..
@@rmetcvideos ❤️ no sir … we never get bored with ur videos…
@@rmetcvideos Sir Any of your videos can never be boring...We look forward to any upload of yours...Sir would request you to make a video on Bulk carrier deck crane hydraulic circuit... Thank you.
u mail to me on ramesh@rmetc.co.in...pls mail the circuit. If I have the material on that crane in my content I will try and answer you.Crane contents arerelevant only for bulk/container guys..In fact I conduct Crane courses for Companies directly.. for chief engineers, 2Es ETOs and superintendents ..so another constraint why I cannot put it out on public domain ..hope you understand
Very nice and up to the point explanation.
Will you please explain what is difference between 2 vanes, 3vanes, 4 vanes? Why can't we use more than 3 vanes? Like 5 vanes, 6 vanes etc
2 Vanes does the job. More vanes will add complexity.By increasing the vanes we may utmost increase the Torque handling capability...If the size restrictions are not there and we can do the job with 2 vanes -- why extra vanes with more comlexity??
Sir i love the you makes things so easy to understand.Please make a video on starting air system.
Hello Sir it's really a amazing video with great information., But I have a small doubt that when oil exerts the pressure on vane to move port the return oil has to pass through check valve and the check valve is actuated by the same oil which is used for turning but my doubt is that when the oil gets in check valve line there is a clear resistance free passage for oil to return to the tank and on the other side of the check valve there is pressure of return oil so how it is actuating the check valve instead of directly returning to the tank ??
The oil is returning resistance free..correct.. but the inllet oilTurning the vanes is full of pressure because the Physical Rudder is generating the resistance...This pressure can easily open the check valve
@@rmetcvideos Ok Sir I got it., Thank you 😊
Pls make a video on manouvring diagram.
THANK YOU SIR.
Love you Bda Sahab .keep it up .

Hi..how are you. From Karachi--correct..Hope u had a great trip ?
Very helpful video sir,thank u .
Great video sir please put more videos regarding marine auxiliaries
Great Explanation. Sir pls make video on Windlass Hydraulic circuit and its components also.
Thanks. Soon
please share information on control systems. two element main engine jacket water temperature controller. Boiler water level controller.
interesting..will do in due course
Sir kindly post video about steering gear locking arrangement...I have huge doubt regarding that topic..I can say your videos r best for doubt clearance...
every steering gear needs to be hydraulically locked to retaijn the rudder position. It is already a part of this video. Hydraulic locks are also talked about in My earlier video on steering Gear Rules
Sir pls took class for class 2..awaiting for you if u r having time..can u share your contact number?
can whatsapp me on 9381013180...But since I am not a faculty in any institute, I wonder If I can answer all your question 😄
Excellent video sir
Nice one sir 🙌
Jabardast jindabad sir
Sir please make a video on indicator diagram and power card and power measurements of main Engine
Please Please
Thankyou For all tbe videos....they are quite helpful in my exam preparation....I request you to please consider my topic and have a talking about it...
Hi..in this electronic era ..??
awesome video sir! sir if possible please make some videos on hydraulic circuits for deck equipment like mooring winches etc
Ha ha..Though Hydraulics is my special area of interest.. Hydraulic Videos are not doing well at all.They hardly get any view as compared to the other videos.This Rotary vane video is doing very badly ..actually...
All of your videos have helped many candidates including me to clear class 2 exams sir..Have shared the channel with many of my friends and colleagues.Channel will definitely gain recognition in coming days!
Sir i have a doubt, what about the oil on the other half of the actuator, it has to escape back to the tank in order to facilitate smooth movement of ruuder without any hydraulic lock..how is it achieved?
Thru Pilot operated check valve
sir could you please tell me which is functioning as the bypass valve in the arrangement that you have shown? cuz i worked on a ship with rotary vane steering gear made by rolls royce. the circuit is almost the same. i have checked the instruction manual. i can't really figure out the bypass valve(being a cadet, haha). please sir help me
I am not able to comprehend your question..BYPASS ..valve??Anway I will try ..The Pilot valve (4) in the center postion can be called BYPASSING or SHORT Circuiting..That is to Unload the pump when no control signal is given ..The other valve --on top- (6) -we are calling as SHock ABsorber..This also can be argued that it is Bypassing the OIL to the other side..Hope I have answered your question by accident Ha HA
Amazing sir
Thanks bada saab
thank you very much
All respect chief
too good sir
Thanks sir, 👍
great
Thank you sir!
mail to me on ramesh.rmetc.co.in. Dont have too many pics.,Not sailed for more than 5 years now. Still I will try my best
Thanks Sir
Sir, In framo system one oil heating valve is there which reduces the pressure of oil and due to this sudden reduction of pressure oil gets heated, can you please explain physics behind this that how oil gets heated if pressure on it relived suddenly.
Energy required to create a flow at any point in a hydraulic system is P(Pressure) x Q (Flowrate).SO pressure before the heating valve is more and Pressure after the heating valve is less. So Press diff x Flow Rate is the amount of heat generated
Hi sir, normaly we fit filter on suction side of the pump, however, in hydraulic systems it is fitted on discharge side. Any particular reason for the same.
we cannot fit filters on the suction side. AT best we can fit Strainers. Filters need to be about 10-20 Microns to be effectiv ein Hyd system which cannot be fitted in suction side since it will cause cavitation

What is the location of the relief valve in the system ?
I guess --you are able to see--the Relief valve in Pump assembly and Shock Valves near the Actuator valve block
How do we fill up oil ?? And how we remove air
Most of the circuits with feed pumps have a self priming system.Operating the system on no load in either direction for a couple if times shud do the trick Additionally there are purge points.You can check up by operating them.
How we achieve the sealing effects in vanes sir
we have Sealing Strips. These are available in YOuTube in some of the vidoes showing Ohaul of Rotary Vane steering gear ..
I think your circuit diagram explanation of the oil flow is wrong. If the rudder turns the way you have explained in the video, the ship will steer towards the starboard side.
Very True..Thanks for pointing it out. Maybe I was not concentrating ...
