Orientations and different types in hydraulic seals

            

                    There are plenty of tools and equipments that are required to carry out industrial and manufacturing processes. The hydraulic seals are one such useful tool that can be used for a number of different purposes. There are, in fact, different hydraulic actions, and each of these actions requires the usage of specially designed tools. These seals are designed to assist in transferring power from a hydraulic system to the linear motion by containing the oil for the pressure. If the oil is not controlled, the pressure within the system will pass, and this in turn, will result in the failure of the entire system. In addition to that, these seals can also keep away the dirt from the system, by means of which the entire hydraulic action remains efficient.

Hydraulic seals are products that include types such as rod seals, flange packing and U-cups. They are specifically designed for applications that require high pressure such as those of hydraulic cylinders. It is said to have a wide array of orientations and different types. Before going further into the orientation and types of hydraulic seals, here are some things to consider when purchasing such industrial products. The diameters of the outer shaft, inner seal and housing bore should be specified. Thickness and radial cross section should also be included in the list of considerations. Service limits such as operating speed and pressure, vacuum rating and temperature should be dealt with accordingly. There are various sealing directions for hydraulic seals.

The first on the list is called a rod seal. A rod seal is a type of radial seal that is fit specifically into the housing bore. The sealing lip is found in contact with the shaft. The second type is known as the Piston seal. This is yet another type of radial seal and is a variation of the rod seal. Instead of the sealing lip found in contact with the shaft, the lip goes in contact with the housing bore. It is in the shaft where the seal is pressed accordingly. The other types of sealing orientations are symmetric and axial seals. A symmetric seal, as the concept implies, work symmetrical or equal to the rod and piston seals. The axial seal on the other hand, goes in contact or in axis with the housing component.

There are two categories for these industrial products. These are dynamic and exclusion seals. A dynamic seal is one that is used in order to separate a fluid from possible contaminants. It is utilized in order to put a gap between moving and non-moving surfaces like those found in piston ring applications. When considering dynamic seals, it is important to focus into a variety of dimensions like inside diameters, outside diameters, axial cross section, radial cross section and housing bore.


Exclusion seals are those that are used in order to separate contaminants from machine bearings. They remove any debris from moving shafts. These hydraulic seals can be sub-classified further into V-ring, scrapers and wipers. V-rings are those made out of rubber while wipers are those with lip seals that are flexible. Scrapers are those that contain scraping edges used in the process of removing contaminants from the bearings.
