How were the cylinders of stationary steam engines, steamships and steam locomotives lubricated, via a large oil tank using injection loss lubrication?
An oil circuit like in a car is probably not possible because the hot steam would cause water to get into the oil?
The hot steam is also extremely aggressive
The completely old DM were also supplied with oil by injection-molded lubrication in the connecting rod bearing space from below with their sliding bearings up to below the pistons to the upper connecting rod bearing in a low rotary fence.
In the cylinder liner, these old systems also had so-called oil strip rings with their own drainage at the bottom of the piston at least at 4T.
The very old 2T diesel from the initial development ran without oil stripping and intermediate drainage in the jack for petrol or diesel crankshaft sub-injection with very low speed at large stroke volume per cylinder.
Modern, all of this runs in sliding and rolling bearings pump-assisted by microchannels themselves in crankshaft and connecting rods in themselves for activation lubrication without oil immersion at the bottom in the crankcase bottom.
Within a conventional steam engine, there are actually very few parts that have to be actively lubricated…: cylinders and sliders would be the essential components. And this can be smeared relatively easily even with, for example, simple displacement oils, if the oil residues in the condensate do not interfere.
All other movable parts can be lubricated from the outside.
And as long as it is not a closed system with condensate recovery, oil residues in waste steam are also no problem.
Hello
These places were supplied with lubricating pumps with oil
