Picking the Right Mechanical Seals to Use
Picking the right mechanical seal seal to use for your machines and installations is a very easy but tricky process. There are plenty of options available for you when you go about choosing which ones to use. Aside from this, there are also other alternatives you can use if you do not want to spend too much of your budget in these seals.
Some of the most common alternatives to a mechanical seal are gland packing and other similar gasket types. But most engineers prefer using mechanical seals since they are more convenient, durable, and can last them longer when used.
Factors to Remember When Selecting Seals
There are basically three important things to remember when you select which these seals to use for your installations.
First, check for chemical compatibility. Most installation where they are used usually involves pipes wherein chemicals usually flow during use. Make sure that the materials which your seals are made of won't corrode with repeated exposure to these substances.
Also take into consideration the cleaning agents you will use for your installations. Check if these solvents will react negatively with the materials your seals are made of. Chemical reactions are common especially for seals made of non-metallic materials.
Next up, make sure that before you apply the seals that the seal faces stay together. Make sure they are closed shut. If you are dealing with hazardous chemicals, even minor leaks can pose as serious health hazards to those working on the machines. It can also hasten the deterioration of your mechanical seal and the assembly itself.
Lastly, you should know that a good mechanical industrial seal is one that lasts you until the carbon face is all worn out. If the seal uses other materials, then it has to last until everything is worn away and this should take a few months. Be aware though, that seal failures happen from time to time though these can easily be rectified if the proper maintenance routines are carried out.
Types of Mechanical Seals
They come in different types. This makes them all the more convenient to use since you can choose what size, shape, and material your seal should be made with. One of the most common seals used in construction projects is the hydraulically balanced seal.
This seal has a lot of positive things that makes it appealing to engineers. First, they usually work in whatever environment temperature they may be in. They are also very easy to apply and maintain as compared to other seal types. They can also withstand tremendous amounts of pressure, which is very useful if you are planning to install the seals into machines and not just pipes or drainage.
For special occasions, you can use seals with metal bellows. This type is perfect if you are planning to use them in machines that work in extremely hot or cold temperatures. They are very durable even in these extreme circumstances. As was mentioned above, they are made from other light materials like Teflon, carbon, plastics and the like.
