FSC 2820: An Introduction to Reciprocating Steam Engines and Their Related Components

When it comes to the procurement of reciprocating steam engine components, Federal Supply Classes (FSCs) provide a standardized and efficient means of identifying and procuring exact items of need. As a part of the Federal Supply Classification system managed by the United States DLA, FSCs group items of supply together based on their characteristics or uses, simplifying sourcing processes for many. In this blog, we will provide a brief introduction for FSC 2820, which focuses on reciprocating steam engines and their related components.

What are Reciprocating Steam Engines?

Reciprocating steam engines are a form of heat engine that is capable of transforming the thermal energy of steam into mechanical power that can be harnessed for work. They typically operate with the use of a piston-cylinder arrangement, where the steam pressure created through boiling or other means drives the piston back and forth. This linear motion is then converted into rotary motion through connected assembly parts, allowing for various machines to be driven when connected. Reciprocating steam engines have played a significant role in history, continuing to find use with their various benefits.

The Basic Applications of Reciprocating Steam Engines

Reciprocating steam engines were widely used during the Industrial Revolution, where they powered locomotives, ships, factories, and various other industrial machinery. While they have been largely replaced by internal combustion engines and electric motors in many applications, they are still used in some specialized areas. For example, they are popular in various industrial processes, as well as for electrical generation in certain areas or industries.

Common Components Organized Within FSC 2820

Cylinders

Cylinders are the heart of countless reciprocating steam engines, serving to house the piston assembly and provide the space necessary for steam to expand and move through the system. With the intensive pressure levels and temperatures present in steam engines, cylinders are engineered with robust materials.

Pistons

Pistons are the moving parts within cylinders, driven by steam pressure while being connected to a crankshaft to transfer energy. Pistons are snugly fit within the cylinders to prevent steam leakage, promoting reliable operation.

Valves

Valves are used in reciprocating steam engines to manage the flow of steam as it moves in and out of cylinders. They are also commonly timed to ensure that the steam is admitted at the appropriate point in the piston's stroke.

Cranks and Connecting Rods

Cranks and connecting rods convert the linear motion of the piston into rotary motion, with the connecting rod connecting the piston to the crank. As the crank rotates during operation, output is provided.

Flywheels

In order to promote a smooth output of energy from the engine, components known as flywheels are used. They are large, heavy wheels that connect to the crankshaft, storing rotational energy.

Governors

Governors are used to regulate the speed of an engine under varying loads, achieving this through the control of steam that is admitted to cylinders.

Bearings

Bearings support the rotating parts of an engine, reducing friction to promote smooth operations. The proper lubrication of bearings is essential for preventing wear and tear.

Lubricators

Lubricators deliver oil to moving parts of an engine reducing friction and wear to promote the longevity of all assemblies.

Condensers

Condensers cool and condense exhaust steam, creating a vacuum that increases the engine's efficiency.

Popular Types of Reciprocating Steam Engines

Several types of reciprocating steam engines have come about through history, each with its own unique characteristics and applications. Out of all that is available, the most notable examples include simple engines, compound engines, and triple-expansion engines.
