An Introduction to Mechanical Seals

Devices that are used to prevent leakages by joining various mechanism are referred to as mechanical seals. Additionally, the seals, prevent leakages by holding pressure or even by eliminating contamination. The efficiency of the mechanical seals is reliant on the adhesion in the instance of sealants and compression in the event of gaskets. It is of utility to comprehend additional methods of forming a seal before investigating how mechanical seals operate. One of the commonly used traditional seals is the Gland packing. The Gland packing is a made up of rope like material that is plaited and crammed around the shaft – physically padding the cavity between the shaft and the pump housing. In spite of the Gland packing seals being commonly used, a large number of households are switching to the mechanical seals due to numerous reasons. This is due to the fact that the Gland packing seals requires pressing besides the shaft so as to lessen outflow, this implies that pump will require more power in order to turn the shaft hence wasting energy. Moreover, the Gland packing need a lot of water to cool the due to friction of the shafts. Moreover, the friction that occurs as a result of the rotating shafts causes wearing of the shafts which cause increased leakage. Also, it is very costly to repair the worn out shafts as a result of the friction between the rotating shafts.

People have various reason as to why the use mechanical seals. These include, when using a mechanical seal, there is no visible leak, this implies that the seals do leak vapor when the fluid reaches the atmospheric side of the seal faces. In addition and the casing of the mechanical seals do not destroy the shaft of the pump. The daily maintenance cost is lowered when using a mechanical seal since they have the ability of self-adjusting when their faces begin to wear due to friction. Furthermore, the Apex Cartridge mechanical seals use less water compared to the traditional seals and also there is less corrosion of a plant equipment in the event that the product is contained in the pump. A type of mechanical seal that is used in rotating gear, such as thrusts, blenders, blowers, and compressors is known as an end face mechanical seal. As soon as a pump functions, the fluid might leak out of the pump between the rotating shaft and the stationary pump casing. Moreover, the mechanical seal face geometry is considered to be the one of the most critical design elements within a mechanical seal. The balance diameter, the centroid setting, and the surface area are some of the seal face properties. Supplementary properties of the seal include the surface finish, the drive mechanism, and the face topography.
