DESCRIPTION
Mechanical seals are important for the general functioning of machines and hence buying good quality seals becomes a crucial task. There are things that you need to check before you actually buy a duo cone seal for your industry. - PowerPoint PPT PresentationTRANSCRIPT
What Are Mechanical Seals? Mechanical seals are components that are used to seal equipment (rotating ones) to ensure that the liquid inside the equipment does not leak out. In rotating equipment, there is always a danger of the content flowing out between the rotating shaft and housing case. The mechanical seal, which contains a spring, rotary seal face and stationary seal face, prevents the liquid of any kind, be it water, steam, oil, etc. to come out of the machine, thus ensuring its smooth functioning. Mechanical seal is used in a variety of industries. It is used in pumps, agitators and mixers.
What Are Mechanical Seals? Although the purpose of all types of seals is the same, the type of seal used would depend on the industry for which is it is used. Different types of mechanical face seals, also called duo cone seals, include balanced and unbalanced seals, pusher and non-pusher seals, conventional mechanical seals and cartridge mechanical seals. Each of these types has specific characteristics that match certain requirements. As mechanical seals are quite reliable mainly because they prevent 100% leakage and also because they last for a long time, they are the most commonly used sealants in most industries.
Things to Check whileBuying Mechanical Seals
Chemical compatibility:
◦ It is important to check whether the materials used to
make the seal are compatible with the fluids or liquids in
the system.
◦ Sometimes, the chemicals in the fluids may not be
suitable for the material used on the seal.
◦ For instance, halogens (chlorine, bromine, iodine, etc.)
are not compatible with Teflon coated seals.
CONTD.. Temperature limits:
◦ There are some temperature limitations that you must
adhere to while selecting the appropriate mechanical seal.
◦ For instance, seals made of ethylene propylene rubber
would not be able to prevent leakage of fluids above 150
degrees Celsius.
◦ Moreover, it may also spoil or damage the seal. Hence,
make sure that the seal you buy can withhold the
temperature that you need for processing.
CONTD.. Correct fit:
◦ This goes without saying! If the mechanical seal does not
correctly fit the equipment or machine, the chances of
leakage becomes high.
◦ Therefore, it is important to make sure that the seals
stay together, so that there is no leakage or damage to
the surfaces.
CONTD.. Seal life:
◦ As mentioned earlier, mechanical face seals or
duo cone seals are used because they last for a long
time.
◦ When the carbon face of the seal gets worn away, it is
time to change it.
◦ However, sometimes leakage happens due to seal failure
too. This condition can be rectified.
Importance of Mechanical Seals
Mechanical seals are important for the general functioning
of machines and hence buying good quality seals becomes
a crucial task.
There are things that you need to check before you
actually buy a duo cone seal for your industry.
Keeping these points in mind would ensure that you buy a
seal that would do its work efficiently for a long time.
