All vedios are really good and very easy to understand , please make more vedios on all topics , especially if you can cover the auxiliary engine ,it will be very helpful
Thank you for your response and support!!!! Please do share this post on your facebook and whatsapp status!!!! Marine Engineering hub aim is to bring all our marine personnel to this platform
Hydrostatic mean pressurized lubrication.. But the motive is to make sure that full film lubrication is achieved in Crosshead. For that this arrangement is made by Man b&w engine. I have told that by this arrangement we are ensuring that instead of boundary lubrication scenerio which was there earlier design is eliminated and full flim lubrication scenerio is tried to maintain Thank for watching and keep supporting and sharing knowledge!!!!
Lubrication. Oil is injected 20 degree before BDC or 20 degree Before TDC please clear it. At 4:30 u told that lube oil feed 20 degree Before BDC and in your writing material u mentioned at 20 degree Before BDC please clear it sir. Thank you
Bro ur told only lower surface bearing but why need to check clearance in top bearing, it means top bearing also fitted oil grooves and hydrodynamic lubrication, it is the same or not
Clearance are always taken opposite to the load acting surface, main bearing load acts on bottom half clearence taken on top,crank pin bearing load acts on top so clearence taken on bottom side,Next about lubrication oil wedges are formed which carries load as cross head bearing has only oscillation movement not rotating fully.
Simple and very informative video.
Thank you sir. Very useful.

Guru ji very very useful videos u r giving
Thank you !!!!
Please make vedios on starting air system of man b&w ,main air , control air, overlap n ll...
It’s very helpful sir..!! Do more..!!
Sure!!!!
Keep supporting!!!!🙏
great effort
Nice bro easily understood everything
Thank you for your support and response!!!

What all crosshead clearences are taken and how, plz explain
I read that crosshead is lubricated by hydrostatic type... N u have told hydrodynamic.. Pls explain
Hydrostatic mean pressurized lubrication..
But the motive is to make sure that full film lubrication is achieved in Crosshead.
For that this arrangement is made by Man b&w engine.

Bro some surveyor ask why important of lower surface bearing and top bearing what is the use
Lubrication. Oil is injected 20 degree before BDC or 20 degree Before TDC please clear it. At 4:30 u told that lube oil feed 20 degree Before BDC and in your writing material u mentioned at 20 degree Before BDC please clear it sir. Thank you
And in your writing material u mentioned that lube oil is feed 20 degree Before TDC......please clear it sir
It's after BDC bro because when piston moving upwards that time it's easy to inject oil for crosshead lubrication.....
Possible to check the lower bearing
Bro ur told only lower surface bearing but why need to check clearance in top bearing, it means top bearing also fitted oil grooves and hydrodynamic lubrication, it is the same or not

Hello, video is very useful
Can you enlighten us with different Cross Head Bearing in detailed way!
Please watch my next video already I have uploaded on type of bearing!!!!

Sir which type of separate x head pump is used in sulzer engine to increase the pressure from 3-4 baar to 12 to 14 baar ??
gear
gear pump
screw pump
Bro I confused, what type cross head use in hydrodynamic lubrication
👍👍
