Water Level/de: Difference between revisions

Revision as of 14:02, 12 March 2025

When running steam engines , the most critical responsibility is to maintain a nominal level of water in the boiler . This is done by observing a water gauge and adjusting the water level accordingly. The water level should always be visible within 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.

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

Water is fed to the boiler from storage using an injector . It is dumped from the boiler using a blowdown valve, usually found in a vehicle's cab .

Der Wasserstand wird außerdem beeinflusst von der Wärmeausdehnung des Wassers. Wenn die Wassertemperatur steigt, steigt auch der Wasserstand, ohne dass zusätzliches Wasser in den Kessel gelangt.

Der Wasserstand ist zudem abhängig von der Gleisneigung und Schwappen des Wassers. Wenn eine Lokomotive bergab fährt, erscheint der Wasserpegel niedriger als auf einer ebenen Fläche und umgekehrt.

-Maintaining a proper water level in the boiler is critical. This is done by observing the water gauge and adjusting the amount of water in the tank accordingly. The water level should be visible on the water gauge at all times. This range typically shows between 75% and 85% of the boiler height, which is the intended range of operation. Blowdown valve is used to dump water from the boiler, while the injector is used to add more. Having the water level above the gauge leaves less than optimal room for steam to generate in and may overflow to the cylinders, potentially causing major damage. Having the water level below the gauge can be even more catastrophic. If the firebox is sufficiently hot and its top surface (known as “crown sheet”) protrudes above the water level, it can melt, causing the pressurized boiler to explode.

-Im Notfall eines zu niedrigen Wasserstands, ist eines der letzten Mittel zur Verhinderung der Explosion, durch das vollständige Öffnen der Kesselspeisepumpe mehr Wasser in den Kessel zu fördern. Zudem sollten sofort die Kohlen aus der Feuerbüchse abgelassen werden, in der Hoffnung die Temperatur zu senken, bevor die Feuerbüchsendecke schmilzt.
