hydraulic seals - its orientations and types

by:DMS Seals     2020-06-02
Hydraulic seals are Rod seals, flange filler and U-cups.
They are designed for applications that require high pressure, such as hydraulic cylinders.
It is said to have a variety of directions and different types.
Before further exploring the direction and type of hydraulic seals, there are some issues to consider when purchasing such industrial products.
The diameter of the outer shaft, inner seal and shell hole shall be specified.
The thickness and radial cross-sections should also be included in the list of considerations.
Service restrictions such as operating speed and pressure, vacuum rating and temperature should be handled accordingly.
Different sealing directions these industrial products have different sealing directions.
The first one on the list is called Pole seal.
The rod seal is a radial seal specially installed in the housing hole.
It is found that the sealing lip is in contact with the shaft.
The second type is called a piston seal.
This is another radial seal that is a variant of the rod seal.
The lip is in contact with the housing hole, not the sealed lip in contact with the shaft.
It is located on the shaft of the corresponding pressed seal.
The other types of seals are symmetrical and axial.
As this concept implies, the symmetrical seal is symmetrical or equal to the rod and piston seals.
On the other hand, the axial seal is in contact with the shell parts or on the shaft.
Types of hydraulic seals these industrial products are divided into two categories.
These are dynamic and exclude seals.
Dynamic Sealing is a seal used to separate the fluid from possible contaminants.
It is used to leave a gap between movement and non-movement
Like those moving surfaces found in piston ring applications.
When considering Dynamic Sealing, it is important to focus on various dimensions such as inner diameter, outer diameter, axial cross-section, radial cross-section, and shell holes.
The exclusion seal is a seal used to separate contaminants from machine bearings.
They remove any debris from the moving axis.
These hydraulic seals are divided
Further divided into V-
Rings, wipers and wipers. V-
The ring is made of rubber and the wiper is made with a flexible lip seal.
A forklift is a scraper that contains scraping edges used in the process of removing contaminants from the bearing.
