Different Types of Mechanical Seals and Perfect Scenarios to Use Them
In an engineering project, mechanical seals play a great role in most of the activities such as constructing buildings or laying pipelines. It can be a cumbersome process to choose the best mechanical seal if you are not aware of the factors that you must consider in your choice. You might be lucky if the project specifies the type of mechanical seal that is appropriate and you would directly go for it. However, there are no such specifications, and it is your responsibility to make a choice, then you will require some little knowledge on various types of mechanical seals and different occasions when they are suitable.
If you do not know how to make the right choice for your construction project, you can find assistance from seal manufacturers and suppliers. The manufacturers and suppliers might have the good will of helping to select the best mechanical seal, but the seals might not be appropriate for your project because they do not have the details of the project. You own the project and know every detail about it, and therefore, it would be best to some basic information about mechanical seals that would help you in choosing the right seal for your project.
There exist various types of seals that you can select for your project. Most people use the hydraulically balanced seal for their projects. The main advantage of using this seal is that it generates less heat and it can also handle high pressure when in use. You need to make certain considerations before purchasing this seal, and for instance, you will have to calculate the estimated pressure in the pipe and if it exceeds 400 pounds per square inch then it best that you use it.
There is also a stationary mechanical seal which is suitable for projects that have misaligned connecting machines. For instance, a pump and its driver or a stuffing box that does match its rotating shaft. In overall, this type of seal is suitable for machines or pumps that work at high speed.
Some project might emit heat in the process, or the project is carried out in an environment of high temperature and in such a scenario, you will need metal bellow seals. Metal bellow seals are not only useful in high-temperature regions, but they can also be utilized in extremely cold environments.
Some machines might have two way systems, and their suitable type of seal becomes the dual mechanical seals. These seals are also helpful in emergency scenarios such as when there is a shutdown or power interruption.
Non-metallic seals are necessary for connecting none metallic parts such as plastics, Teflon, and carbon. You can count on them to effectively seal whatever liquid or gas that is in the pipe. Their price is lower than that of metallic seals.
