Quisiera saber el mantenimiento y reparacion de una valvula de escape MAN B&W pla os y components
@andyvan5692 Жыл бұрын
great video, but with the safety valve, you should torque the valve body on the test fixture to, as this ensures the spring is under the same pressure that it would be on the exhaust valve itself, so the setting point will match the usage setting.

Although I'm never going to work on diesel engines this size, I've watched several of these videos and found them really interesting. No valve springs, or cam shafts, all done by compressed air.
@scowell7 жыл бұрын
Looks like the valve is held up by air, and pressed down by hydraulic. I agree... fascinating!
@EnriqueJColl7 жыл бұрын
Jim Prong.....yes, it took me 14 minutes to figure out that these valves were pneumatically control...GEEEZUS...!!!
@scowell7 жыл бұрын
I believe the valve is controlled hydraulically, with a pneumatic spring.
@EnriqueJColl7 жыл бұрын
scowell.....yes, you are right. The hydraulic opening of the valve was left in my inkpot when I wrote the comment. The closing of the valve is passive while the opening MUST be immediately active. This system sure saves a lot of camshaft and rockers and rollers and pushrods.

Are air tools or electric tools not allowed? Impacts and ratchets mainly. I figured maybe it's because they might make a spark in a dangerous environment

So the images depicted in the video are used in the enritchment of structured sodiums and finite powders.

derived from an element source such as 5 oleum or glycol, or compressed air, negative pressure and hydrogen chloride or steam. many things you can do with nitrogen, hydrogens, etc ..... many application such as catalyst powders, enritched irons for mettulurgy etc ......

Why don't you measure the diameter of air cylinder? In some case, it was worn out and cause air leak and the valve stem can't close.

I'm having a doubt, Why lub oil is filled before placing the air piston in air cylinder...??
@kultigintolunaykaman12404 жыл бұрын
after mounting it on the main engine, it may not be lubricated at the first move so you have to add lub oil inside the air cylinder to avoid damage

I was surprised to see that they do not instruct about slightly oiling the ´´o´´rings before installing. they could use silicon grease that it´s non flammable for the air cylinder.

Hii..I think the air is supplied with L.O for lubrication purpose of the air spring piston which moves up & down and bit of air is also supplied to the guide bushing which will result in cooling & lubrication of the bushing.
