Different Types of Aircraft Piston Rings
For those working outside of the aviation industry or new to it, it’s pivotal that you understand the makeup of an aircraft, right down to its very foundations. The piston ring is a part of that, but note that there are many different types of piston rings that you must also familiarize yourself with. But to get to basics, know that a piston ring can reduce or completely stop leakage of gas pressure that emanates from the combustion chamber. Not only that but it can mitigate the amount to a minimum of the seepage of oil into the combustion chamber.
Piston rings must be inserted into specialized grooves but they must also be taken and attached to the walls of the cylinder where they will experience lubrication and where a gas seal will be formed. To go over piston rings and the basics, most piston rings are constructed of high-grade cast iron and after the rings are made, they are then ground to the required cylinder wall. The next step is that they are split in two so that they can be placed over the outside of the piston and into the ring grooves that are machined in the piston wall. Because the intention behind the seal is to secure the space between the piston and the cylinder wall, it must be so that they must fit the cylinder wall snugly enough so as to have a sealed gas fit. Both parts must apply enough pressure on every point of the cylinder wall and should be able to make a tight gas seal on the grooves of the ring.
In regards to pressure rings, another type of piston ring, its job is to forestall ignition gases from departing past the cylinder during motor activity. They are set in the ring grooves promptly beneath the cylinder head. The quantity of pressure rings utilized on every cylinder is dictated by the sort of motor and its plan, albeit most airplane motors utilize two pressure rings in addition to at least one oil control rings. To permit the excess oil on the crankcase, openings are penetrated in the lower part of the oil control cylinder ring grooves or in the terrains close to these sections.
Oil control rings, on the other hand, are set promptly beneath the pressure rings or more the cylinder pin exhausts. There might be at least one oil control rings for each cylinder; two rings might be introduced in a similar notch, or they might be introduced in isolated furrows. Oil control rings direct the thickness of the oil movie on the chamber divider. On the off chance that a lot of oil enters the ignition chamber, it consumes and leaves a thick covering of carbon on the burning chamber dividers, the cylinder head, the flash fittings, and the valve heads. This carbon can cause the valves and cylinder rings to stick on the off chance that it enters the ring scores or valve guides. Likewise, the carbon can cause spark plug failing just as explosion, pre start, or unnecessary oil utilization.
