When machines and other kind of equipment are exposed to constant usage, their efficiency reduces due to wearing down. Efficiency can be accelerated if the parts in the machines are maintained properly. It is important to prolong the lifetime of these machines by subjecting them to frequent maintenance services. Wear liners are useful in ensuring that the most used parts of the machinery are covered to minimize wear.
There are different methods of lubrication. The techniques have advanced in effectiveness. Although a lining is installed to reduce the magnitude of wear, it is also subjected to different aspects that lead to wearing off. It is important to replace the outer layer from time to time to ensure that the inner parts do not weaken quickly. The following are causes of liner wear.
Friction is produced through sliding of two surfaces adjacent to each other. There are different factors that lead to this kind of friction. They include the type of materials, the speed that these two surfaces are moving at and the temperature in that space. When the level of friction is high, the materials in contact weaken resulting to tear. Friction is known to be a leading cause of wear of different parts of machines.
When particles are present between the moving parts, the results might be tearing down of the materials. In large machines, such particles are produced during combustion. They lead to scratching which, when exposed for a long time, the material becomes weak and can no longer serve the purpose. Machine owners are advised to check on the parts that are exposed to frequent use to remove these particles. This prevents abrasion from occurring.
When fuel oil is burnt, large contents of sulphur are released. Combustion involves production of sulphur contents in large amount. These contents can lead to corroding of metals. The presence of sulphur and moisture in the burning area produces sulphuric acid. This acid is highly corrosive especially in cool areas. Liners in this area corrode easily and the material becomes weak with time. The problem can be eliminated by use of an alkaline substance that neutralizes the acid.
Some metals are shiny when new. However, this appearance changes with time as the metal is used. When abrasion occurs due to continuous usage, this roughness wears the lining away. It is caused by inadequate lubrication between the colliding metals. The inadequacy is as a result of high level of heating inside the machine. With this, the liner becomes ineffective and the life of a machine is shortened.
Another minor problem that resembles abrasion is formation of tiny marks on the surface of the liner. The small marks are due to the irregular movement of pistons against the protective layer. They are also created because of insufficient lubrication. This problem might not be destructive at the early stages. However with time, the efficiency of protective coat may reduce.
These are several causes of tear in liners. Since the function of liners is to protect the metals inside from wearing off, it is important to check that they are in good condition. They are exposed a higher degree of friction and corrosion when compared to the metals. Proper maintenance and constant repairs are necessary to keep the machines functional.
