Water Level/ru: 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 .

Уровень воды также зависит от уклона пути. При движении локомотива в под гору, уровень воды будет казаться ниже, чем при движении по горизонтальной поверхности, и наоборот. В случае крайней необходимости, для предотвращения взрыва котла можно сбросить пар при помощи крана сброса, сифона или даже продувательного крана цилиндров.

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.

-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.
