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.

Abrasion is another cause of weakening in linings. In case there is presence of small particles between these moving parts, the liner can be weakened. Machines that have combustion spaces experience this common problem. Particles produced in this part lead to scuffing of the layers in contact. When these particles are not eliminated in good time, they can be destructive. Machine owners should confirm that such areas are cleaned frequently to avoid abrasion.

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.

As pistons move inside the liners, the shiny surface disappears and forms an abrasive metal. Due to constant movement, the metal increases wearing rate of this lining. This factor is caused by lack of enough lubrication. The insufficient lubricant comes as a result of heat produced during movement. With this the liner is less efficient thus cannot protect the piston inside well.

Another result of insufficient lubrication between a liner and the metal is formation of small marks on the liner. The scratches are from the uneven movement of the covered part with the coat. Though the aspect seems minor, it can affect the liner as time passes. Wearing off decreases the efficiency of the coating thus the metal inside is not protected in the right way.

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.
