Good hydraulic piston seals do not come straightforward. Instead, good ones come after consideration of many factors.
Only after consideration of the right factors, can you buy the right piston seals for your business.
The interior of a hydraulic cylinder is complex, with many seals to perform different critical functions. And, they keep the cylinders working efficiently.
In addition, the seals protect the internal components from damage due to contaminants, corrosion, etc.
It is not wrong to say that seals are among the most important parts of a hydraulic system. Without those seals, the systems will not work properly.
It is crucial to be familiar with the different types of seals in your hydraulic system.
Piston seals are important to attain good cylinder function. As the piston seals restrict fluid from bypassing the piston, they help in maintaining the requisite pressure across the piston to render the essential force for the cylinder to perform properly.
You can regard hydraulic cylinders as actuators that are used in large and small-scale industries, and manual and automatic tools.
With hydraulic cylinders, machines get the force to move a workload. And, the cylinders find uses in machines that push, pull, lift, steer, clamp or enable bringing down heavy loads.
The prominent user industries are–the automotive industry, civil engineering, mining, drilling, warehousing, shipping, and marine.
The right choice of hydraulic cylinders calls for the consideration of different factors, which dictate force, force direction, cylinder mounting style, bore size, stroke length, and operating pressure.
Force
It is the fundamental principle behind a hydraulic cylinder. Typically, the force gets transmitted through the front and back ends through a fluid. And, the force gets multiplied in the process.
Bore Size
The bore size is an important consideration as it determines the cylinder operating pressure. You should ensure that the bore size should ensure operating pressures are in the range of 500 psi to 10000 psi.
Rod Size
Once you finalize a minimum cylinder bore size, you should select the right rod size. Remember, you should ensure the selection of the right stroke length as that can impact the rod buckling strength.
There are instruments to calculate whether rod buckling strength for a given rod size and stroke will be the right one for a particular load.
Cylinder Mounting
You can classify hydraulic cylinders based on their mounting, which are of two types–pivot mounting and straight line mounting.
Now, let us discover the differences between them.
You can use pivot mounting when there is a need to load through an arc. And, these can include mounting, like Trunnion and clevis.
You can use straight-line mounts when you need to move the load in a linear direction. And these include mounting, like rear or front head flange and foot mounting.
Remember that hydraulic seals play a significant role in flawlessly running the cylinder, and preventing oil leakages.
Conclusion
You should ensure that you choose the right seals for your equipment to justify investment and values. Therefore, you should consider the applications, operating environment, and the maximum operating pressure.
We believe that this article will be helpful to choose the right seals for your business.
