Know The Types Of Seals Used In Hydraulic Cylinders

The reason why hydraulic cylinders are in quite a demand is because of their efficient performance. The main purpose of using such a type of cylinder is to make sure even in a different yet challenging situation and applications, things can be sorted easily. It does not matter whether it is the lowing truck that clears the road or the utility vehicle that uses an electrical issue, you shall find a hydraulic cylinder almost everywhere. There are so many reasons for which hydraulic cylinders like DZ Ding Zing Hydraulic Seals are being used. There is a complex configuration made for the better performance that seals downs. This way the pressurized fluids in the hydraulic cylinder system are generated and stay in motion.

Understand The Types

Hydraulic Seals are made of different materials such as briers, polyurethane, and PTEE to name some. Such type of material determines a certain operating condition that restricts because of the type of fluid, pressure and even the fluid chemical computability or temperature. There are two basic categories of this type of cylinder namely:

(1) Static Seals

(2) Dynamic Seals

Static Seals: Talking about static seals to give you a better understanding, the perfect example of the same can be O-ring. This type of seal is located in the groove. There is no specific movement that can be noticed. But yes within its confined space, it works like a gasket. Talking about O-rings, it is a versatile option that is available in different sizes. When you place it in the cylinder housing and squeeze by casing there is a physical barrier that is being created between the casing and housing. It is more commonly used with the backup rings that have the pressure of more than 1500 psi

O-ring can serve many purposes such as you can use it in:

  • Ethylene propylene diene (EPDM)
  • Wiper seal for Hydraulic cylinder
  • Nitrile rubber (NBR)
  • Fluoro rubber (FKM

It is also best to be used in different mineral oils, water, and fluids that are based on air and fluids multitudes. There are some other compounds as well such as Hydraulic and pneumatic seals, silicone and Polyurethane (TPU) that have been used in the static environment.

Dynamic Seal:

This type of sealing is subject to radial movement or say axial movement when there is a pressure built up. There is a piston seal, road seal and even the will seal that you get in such a type of option. The foci of the piston seal are to protect the fluid which is pressurized against leaking across the piston as the system pressure pushes down the position and rod at the head of the cylinder.

With the help of a rod seal, the right pressure in the cylinder can be held. This way the fluid will not leak out and further damages can be protected. If there is any kind of leakage being noticed through the ceiling of the rod then it may reduce the performance of the equipment. There are extreme cases that are rare and that could awaken the environmental issues too.

There are wipers which are popularly known as scrapers. It helps in protecting against the contaminants such as dust dirt and moisture that may enter the colander and then they retract back against the system. If contamination is not controlled on time then it may cause some serious significant damage to cylinder walk, rod, and even other components. Most of the time it is the contaminant that is responsible for the component failure and premature seal failure in the power system of the fluid.

Choosing the right type of seal can be a challenging task. After all, it assures the best possible performance for the application of the hydraulic cylinder. So make sure you take a wise decision and choose the one that would prevent any cause of damages. Always remember, there are guide rings that can work the best for protecting the damages from the site to get loaded. This way any possible risk of metallic contraction to take place between the rotational and axial components from contacting one other can be avoided. It is time to trap the contaminants rightly before they can even reach the most crucial sealing elements. So what are you waiting for?
