Water Level/cs: Difference between revisions

Latest revision as of 00:56, 18 March 2025

When running steam engines , it is of utmost importance to maintain a nominal water level in the boiler . This is done by observing a water gauge and adjusting the water level accordingly with available controls. The water level should always be visible in the water gauge, typically ranging between 75% and 85% of the boiler height.

If water rises above the limit, there are two potential dangers - there is less room for steam to be generated in, and water can overflow into the cylinders , potentially causing them to break .

If water falls under the limit, the boiler can explode and cause catastrophic damage . If the firebox is sufficiently hot and its top surface, known as crown sheet, protrudes above the water level, it can soften from high temperatures and pressure, and lead to the boiler explosion, destroying the entire vehicle.

In an emergency attempt to save the engine from exploding, immediately feed water and dump coal from the firebox.

To feed water to the boiler from storage , there's an injector . To dump water from the boiler there's a blowdown valve. Both controls are usually found in a vehicle's cab .

Hladina vody je také závislá na sklonu. Pokud jede lokomotiva z kopce, hladina se bude jevit nižší než na rovině a naopak. V případě nouze je jedním ze způsobů, jak zabránit výbuchu, vypouštění páry z kotle odkalovacím ventilem, dmychavkou nebo dokonce odvodňovacími ventily.

Water level is also grade dependent, and subject to sloshing. If the vehicle is going downhill, the level will appear lower than on a flat surface, and vice versa.
