Movements of the Mechanical Seals |
Posted: July 12, 2019 |
While mechanical seals take over industries, it is still necessary to take a look at the wide range of all the types. The mechanical seals or agitator seals can feature different types of movements, applications and function which are best understood by categorizing them.
Static mechanical seals are used in opposition to the mating faces of seals which do not have much movement. Static mechanical seals are dependent on the compressor for further definition of their functions. Based on the movement of compressor or the direction of compressor, the static mechanical seals can be called radial or axial.
Another type of the mechanical seals is the dynamic seals. Unlike the condition of stationary seals, dynamic seals are dependent on the movement of the faces. If there is rotation, oscillation or other motions, dynamic mechanical seals are used. Most of the time, performance of dynamic mechanical seals relies on the operation factors of the compressor and pump shaft.
The reciprocating dynamic mechanical seals come into play when there is some reciprocating movement. The inner and outer surfaces on the axis are responsible for this type of movement. Moreover, the reciprocating seals are used for settling between glands where this motion is usually present.
On the other hand, axial mechanical seals are used for applying pressure or squeezing between two surfaces; upper and lower. In order to make sure that the pressure is right, take into notice the dimension of the seals. The axial mechanical seals are otherwise placed on a side which has low pressure in order to limit the movement. O-Rings are commonly used in the axial seals too.
Oscillating mechanical seals are not uncommon in the industry either. However, due to their limited use to faucets, they are less known. Faucet valves use the oscillating seals for movement of the shaft. This type of seals should be used if they offer self-lubrication.
