Choosing The Right Marine Piston Rings For Frictionless Work

A machine, complete with a piston ring in its component, is easier to function. From small tools to large water steamers, piston rings are used almost everywhere. In a ship’s diesel engine, Marine Piston Rings help the most in their combustion chambers.

What is a Piston Ring?

A piston ring is a ring that fits into a groove on the outer diameter of a piston, which is helpful for the proper functioning of an engine. It was invented in the year 1854 and since then it changed the way, machines functioned effortlessly and without friction. A marine piston ring is used in the engine of a ship, which forms one of the most important parts of the diesel engine.

What are the types of Marine Piston Rings?

Marine Piston Rings are classified on their functions and the areas of their use. There are three basic categories in which they are placed. Smaller marine engines make use of any of the three categories, whereas, larger diesel marine engines may have all three of the categories, based on their uses. Here are the basic types.

• Pressure Rings: These rings help to seal the piston and prevent leakage of gas. As these are located on the topmost groove in the machinery of the diesel engine, their main purpose is to trap the leaking of gas inside and transferring heat to the piston walls.

• Intermediate Rings: These also help in preventing gas leakage, but their main function is to provide lubrication to the outer walls.

• Scrapper rings: These types of piston rings also help in smooth lubrication of the machinery, but they differ from intermediate rings in the way they scrape off excess oil from seeping into the cylindrical walls.

How to examine a piston ring for damage:

There are a number of ways of testing whether a piston ring is functioning properly or damaged. Here are a couple of simple ways in which they can be inspected.

• The visual method is the simplest and the most trusted way to make sure whether a piston ring is in good condition. If it shows no visual sign of damage, it can go a long way before being changed. If it shows burn marks or is slightly bigger in size due to excess wear and tear, it needs immediate replacement.

• By using a piece of wood, one can also check for broken rings. If a piston ring springs back to its original size, it is as good as new. But if it does not, it has been broken in its process and needs to be replaced.

• If an entire piston assembly is not functioning properly, it could be that the piston ring is misaligned. Immediate alignment thus becomes necessary.

There are various components in the assembly of a combustion engine. A cylinder, piston, piston ring, a crankshaft, discharge pipelines and Piston Ring Compressors form the major parts. A Piston Ring Compressor helps to compress piston rings on a piston so that they fit on the piston inside the cylinder. It is usually well-oiled so that it lets the piston and its rings function without causing much friction.

For a diesel engine to work effortlessly, these are the points to remember. Also, if one is familiar with its parts and its working, it becomes easier to pinpoint the associated problems and replace them when necessary.
