What Will Affect the Durability of Shaft Seals?

2019-04-23


The durability of any product is always important; can you purchase a product if you knew it will not last the way you expect it to? For you to purchase shaft seals the first thing that comes to your mind is its durability, so that you may not end up regretting purchasing them when they start wearing out faster than you intended.

 

There are important factors that you should put into consideration to ensure that your shaft seals are able to give you quality services and can last longer. But there are also other factors that may disappoint you through reducing the lifespan of your shaft seals. This means that you need to be cautious of how you will handle these factors so as to avoid the expected recurring problem of changing shaft seals. Normally as you might expect, shaft seals should last longer for the period that will almost be at your satisfaction.

 

The following aspects are going to affect the durability of your shaft seals.

1. The aspect of the lubricant that is utilized.

A lubricant in simple terms is a fluid that is supposed to soften a surface area that is rough. It is quite surprising to find out that it is one of the factors that will reduce the life span of your shaft seals. One fact that is known is that the interaction between the seal material and the lubricant is unavoidable; they must work together for good operations of the shaft seal. During the shaft seals operations, both the seal edge and the lubricant are highly visible to the unbearable thermal and mechanical conditions. The exposure is not quite good for your shaft seal since it makes them do more of the work than it is supposed to do. The exposure also allows for the clipping of the lubricating film and passing of oxygen which is otherwise not needed during operations.

 

The seal function is also affected by the vital and flexible change in temperature caused by the lubricant. With high and extreme temperatures on the seal edges the outcomes that follow are; the accumulation of harmful oil carbon, cracking, scorching and also some remains of the seal edges.

 

The lubricant used in these shaft seals should be carefully analyzed in such a way that it will no longer have negative effects while the shafts are in their operations. A good example of the shaft seals that are good at maintaining the lubricant in good order is the metric shaft seals, these modern seals are well designed to cater to the issue brought about by lubricant. Consider putting them on your shafts shopping seals for remarkable results and durability.

 

2. The aspect of pressure.

When you are under pressure your concentration will be affected and most of the time the results will not be pleasing. The higher the pressure the lower the results of whatever works you are supposed to do. The same rule applies even to the shaft seals; when the fluid that is to be sealed is pumped with the pressure the seal lip will be directly affected. The expected high pressure in the seal lip will lead to a reduction of the rotational speed and the velocity in the circumference. The reduced speed means that the friction might be too high that can cause wear and tear to the shaft seal. Metric shaft seals will integrate the shortened seal lip that will reduce both the pressure and flexibility in the contact zones. The reduction of the rotational speed caused by these high pressures also leads to over temperature, and as a result, the seal experiences lack lubrication that is needed for its operations.

 

The best thing about metric shaft seals is that they are specially equipped by a unique geometry at the seal edge. This geometry has the capability of adjusting lubrication in the point of contact, reduce wear and reduce the over temperature condition that might occur. The design used in making these metric shaft seals is such that you can be able to increase expand the area of application in regards to pressure and the rotational speed will not be affected in any way.

 

Pressure applied during the shaft seal operation should not be ignored; you should consider taking immediate actions by getting yourself metric shaft seals for good performance.

 

3. The aspect of the temperature

The temperature always has a part in everything you do, for instance, a change in temperature can make you change your plans anytime anywhere. The same changes in temperature are somehow unavoidable in shaft seals, whether it is hot or cold; there is an influence to the shaft seals that can later be related to its lifespan.

 

When the temperatures are very high the seal materials will experience negative changes in its mechanical features that would, in turn, affect the durability of the seals. Extreme temperatures can lead to the unexpected malfunction of the seal while at the same time the seal lip will be harder than normal and cracks will also be noticed in the point of contact. The high temperatures can be as a result of environmental factors and friction that is normally caused by the seal lip during its operations. The resultant of high temperature caused by friction is normally known as the 'over temperature' since the seal gap temperature is higher than the oil bath temperature.

 

Increased high temperatures also lead to fast corrosion of the medium to be sealed and may also have a negative effect on the extracts that lead to unwanted reactions which cause damages to the seal materials point of contacts.

 

For the metric shaft seals, the story is different because their materials are suitable for any temperature and are oil resistance. They have also been fitted with friction optimized seals that help reduce the heat produced during friction and curb the issue of over temperature in the seal lip.

 

There are other factors that normally affect the lifespan of your shaft seal but the ones mentioned above are most vital and you should take a keen interest in them. You can also put your focus on the metric shaft seals that are well designed to curb the above factors and allow for a longer durability feature.
