Any person working in the maintenance field who has been assigned to repair a pump or gearbox, understand very well that one component that is usually replaced during a rebuild is the lip seal. In most cases, the component gets spoilt when being removed or during disassembly. Note that the lip seals are important to machine features since they help in making sure that the grease or oil do not escape from the container.
The key function of a lip seals chicago il is to prevent contaminants from getting into the lubricants, and they work by maintaining friction. For this reason, they are used in a wide range of application which includes slow-moving machines and high-speed rotation equipment.
For the lip seal to work effectively, it must be designed in a way that it maintains an appropriate contact with the rotating machine. However, this will be swayed by numerous factors which may include choosing the right lip seal, proper installation, and maintenance of the seal once it is installed. In most cases, you will find a newly installed seal starting to leak immediately it starts working. Note that this is usually caused by incorrect installation.
Bear in mind that maintaining a perfectly working lip seal starts right in the choosing process. When looking for a good material, you need to look at the operating temperature, the lubricant used and the application. The commonly used material is nitrile that works well at temperatures ranging from minus 40 degrees F up to 275 degrees F. the nitrile seal lip is used to cover numerous applications in the industry ranging from new equipment to replacement seals. What makes this material the best is that they come with unmatched resistance to petroleum oils, water, and hydraulic oils and they are cheaply available.
Viton is another cheap material is available in the market. They work in the temperature ranging from minus 40 degrees F to a maximum of 400degrees F, based on the compound. Additionally, they offer an excellent resistant to petroleum oils and can be used with gasoline and transmission fluid.
However, there are other seal materials that can be employed with petroleum oil and this includes carboxilated nitrile, highly saturated nitrile (HSN), polyacrylate and many others. All the materials mentioned coming with a specific application and exact range of temperatures. For this reason, make sure that look at the process and environment before settling on the best seal material since a perfectly selected material will avert a costly fiasco.
For you to keep your lip seal in the good working condition, you need to make sure that the oil is clean, cool and dry. Note that any contagion in the oil will reach the patch, leading to the deterioration of the shaft and elastomer. Similarly, if the oil becomes hotter, it will be subjected to wear and tear on the seal. Therefore, lip seals must be kept clean, and covering the seal with a paint coat or dirt around it will generate more heat and degrade the elastomer.
