How To Inspect A Seal Surface

What is a Seal?

Seals are used in a variety of machines. Their purpose is to guard against any kind of leak from gas, water, or air. The main idea in using them is to greatly reduce the loss of any substance in a machine or an engine.

Some of the most common uses for sealants are in vacuum systems. They are complex setups that are mainly used in major industries. Oil is transported through the tank right from the source. Good vacuum systems have a vacuum in the tank that speeds the process along. This allows the oil to travel safely without leaking. This is how most complex industrial equipment runs smoothly.

Unwanted Vacuum Leaks

Unwanted vacuum leaks often occur without much warning. If left undetected, they can cost you and your company thousands of dollars in repairs. Getting your industrial systems inspected for loose parts can save you more time and money.

Vacuum leaks are more serious than you think. They lead to all kinds of problems with your engine. Air can escape into an engine and cause problems with idling, such as stalling or misfiring while running. You could also have trouble with acceleration and fuel economy. In short, you may find yourself using more gas than usual while driving.

What Are O-Rings?

O-rings are specialized parts that are common in most mechanical systems, including engines. They are characterized by a circular design that’s shaped by the letter O. These tiny gadgets are largely responsible for holding two working surfaces together. O-rings guard against air and liquid and will protect both the valve stem and valve guide. In short, they guard against oil leaks in the valve guide and help keep your engine solvent.

O-rings have an amazing ability to hold up to 5,000 psi, which makes them strong and durable for almost anything. Yet it pays to have them inspected periodically. O-rings can be subjected to wear and tear over time. There are ways you can inspect their surfaces to check for erosion and other problems.

Problems With O-Rings

O-rings are strong and sturdy. However, they can face the following problems over time. These problems include:

• Abrasion: Loose dirt or particles can be found right on the surface. These can be the result of excess heat exposure or environmental issues.
• Flattening: Flattening happens when a surface is exposed to excess heat or major compression problems. You may also have volume issues that impact the adhesive surface.
• Degradation: You’ll see a lot of marks, blisters or open cracks right on the surface. These can affect the elastomer, 
which is the surface coating. This may be the direct result of excessive gas consumption.
• Extrusion: These same marks appear due to excess pressure. You may even have parts that don’t fit or are improperly installed. A mechanical inspection is a must.
• Installation Damage: Poorly installed parts have an impact on the surface coating and cause holes or abrasions in the elastomer. If you notice any of these issues, you should call a mechanic right away.
• Over-Compression: The surface will flatten and form tears or splits in a circular pattern. Thermal pressure or excess compression are often contributing factors.
• Thermal Degradation: The elastomer may soften or crack with excess heat exposure or rapid cycling. The elastomer may look shiny. This is caused by air exposure. An inspection should be done at this stage.
• Plasma Degradation: Discoloration and residue form on the surface. These could be the result of sputtering or extreme heat exposure. You may even have improper adhesive or a bad chemical reaction somewhere. A checkup is necessary.

Other Problems

O-rings and other secure devices offer great protection against leaks from inside and outside of the engine. There are a few other problems that often develop with these critical gadgets. One is spiral failure. This is where you might notice nicks and cuts directly on the adhesive.

You may experience inadequate lubrication or a tight and hardened elastomer. These could be two primary causes for gadget failure. Other causes may be faulty equipment or bad installation. In any case, a professional from High Vac Depot can help.

Why an Inspection is Critical

Surface inspections are now more important than ever. The reason for this is any adhesive can erode and get loose anytime. You could experience any of the above problems or you might notice other issues with an engine or machine. In these cases, a thorough inspection can help. You can determine if you need professional service to fix your motor and get everything up and running again.

Ways You Can Perform an Inspection

Doing an inspection on your seal surface is simple. All you need to do are a few simple things. You can begin by wiping down the surface of your O-rings with a tissue or clean cloth. Remove any excess fluids, such as water and oil. This helps you get a more thorough surface inspection.

Next, you do an inspection using your finger. This requires you to wear a latex glove. From there, lightly run your finger over the O-ring. This will help you detect any holes, rips, or tears in the elastomer. You should inspect your O-rings and check for any damage such as nicks or cuts. Any other decision like hair or debris should also be removed. This can give you more accurate results. Any holes or tears should be immediately noted. A professional from High Vac Depot can address the problem and fix it as soon as possible.

Should a Routine Inspection Be Done?

A routine inspection should be done to prevent any problems from happening. How frequently you choose to inspect them depends on the frequency of use. In most cases, it pays to have routine checkups done to check for residue or other damages.
