Reasons Why Wear Liners Reduce Efficiency

By Brian Burns


Machines and other parts of equipment wear out when exposed to continuous usage. To confirm that these machines are working efficiently, there is need for proper maintenance. The life of the machinery can also be prolonged through constant maintenance services. Wear liners are used on different parts of a machine to ensure that the parts are protected from weakening.

Though there are different methods of lubrication, it might not be enough especially when machines are subjected to continuous use. These methods are getting better every day. Once a liner wears out, it is essential to replace it with a better one. Some sectors of certain equipment can wear off fast if they are not protected well. This article has discussed several reasons why the liner can reduce efficiency.

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.

There are different gases produced during burning. These gases are harmful in one way or another. In view of their harm on equipment, production of sulphur in the burning space of equipment is dangerous. In the presence of water or moisture, this content forms an acidic substance. Acids, when they come into contact with metals, cause corrosion. Sulphuric acid is more effective in cool areas of equipment. The liners corrode easily and weaken in a short period of time. However, this can be rectified by use of a neutralizing substance.

Due to the movement of pistons inside, their shiny appearance change. With time a rough surface is formed. This roughness can tear off liners when there is constant movement. This problem comes about when lubrication is not enough between these surfaces. Due to overheating in this sector, the lubricating oil cannot support the purpose. The efficiency is reduced thus the piston cannot be protected.

When there are irregularities between linings and pistons, there is creation of minor marks on the liner surface. These marks resemble those formed through abrasion. The marks are formed when the lubricant oil is not enough between the two surfaces in operation. Tearing occurs on the protection layer and the surface of the piston. Though this may not be destructive, it can affect the machine if not rectified in good time.

These are some of the main reasons why a liner may not serve the purpose in the correct way. The ability of a coating can be appreciated by ensuring that maintenance is done regularly. Since the coating is exposed to higher amounts of friction and corrosion than the parts in protection, proper maintenance is necessary.
