Hydraulic seals are made of different components, forming a seal in motion through the use of liquids. Therefore the elements are crucial in motion reciprocation through the transfer of liquid power. Soft hydraulic seals are made through different materials such as polyurethane and rubber. Like other rings, the hydraulic rings are durable when used correctly. However, wrong applications result in diverse challenges.
Pneumatic Seals for a long time have had a compound development experience which allows the pneumatic engineers to create new designs and techniques for selecting a sealing lip which preserves the lubricator film. Unique compounds are also used for pneumatic sealing experiences and applications.
As a result, there are many ways of maintaining pneumatic cylinders. Besides, some situations can lead to their failure. However, the primary key is the performance period of any pneumatic cylinder seals. Even though you have comprehensive and protective measures towards the pneumatic cylinders, it is essential always to repair them.
Hydraulic cylinders piston seals are actuators that give a stroke of a strong force. Therefore cylinders are used in many industries, for instance, application in civil engineering, manufacturing equipment vehicles, and many more. However, the hydraulic cylinders may experience different problems because of many reasons. Therefore this article will discuss 7 Common Failures of Hydraulic & Pneumatic Seals.
Pneumatic Cylinder Side Loading
This is the primary cause of pneumatic cylinder failure. The energy that is applied to the cylinder’s axis leads to several problems that vastly break down the cylinder. The effect of this to the cylinder is that the bearing wear will be affected; it will also lead to the rapture of the piston rod and failure of the seal, among many more problems.
Lack of enough lubrication
Having proper lubrication to the pneumatic cylinder is crucial. When the inner side of the cylinder is not well lubricated, it is likely to dry out and eventually fail with a disastrous outcome.
All pneumatic cylinders require proper timing so that they can work properly. In complex situations, there are different ways of achieving precise sync. Therefore to attain this, all the pneumatic cylinders have to be maintained well. In case cylinders fall out of synchronization, the machine may not work as required, and this leads to failure of the cylinder. Therefore it is at this time that repair will be needed.
Improper installation of hydraulic seals is likely to cause a severe alarm. Therefore, when the seal is installed incorrectly, it will fail in multiple ways, for instance, unsafe handling cleanness incorrect application process of even contamination. The hydraulic seals are designed in a variety of designs. Therefore consulting the Hydraulic seal suppliers will help you choose the best seal to avoid any mistakes.
This happens typically outside the jetsam and flotsam fitted into the hydraulic rod. The tiny particles get attached to the hydraulic piston, thus causing dirt to the seal. When the seal is dirty, its ability to prevent contaminants from getting into the piston reduces. However, contamination can be reduced through the proper installation of the seal and ensuring the piston area is always clean.
Based on the lubrication typed used in the hydraulic equipment, the seal may operate correctly to fail terribly because of degradation effects. The main reason behind the failure of the hydraulic cylinders is because the chemicals get in contact with a cylinder seal. It is, therefore, likely that the seal manufacturers fail to mention the seal material compatibility. This can, however, be prevented if the buyer seeks more information from the manufacturer before making the purchase
Damaged piston rods and rod bearings
When this equipment is damaged, the hydraulic cylinder is likely to fail. This is a result of poor alignment of the cylinder between the load, and this leads to bending as well as sideloading.
Overall, there are many causes of Hydraulic & Pneumatic Seals failure. However, in case you experience any of the discussed failures, it is advisable always to contact a reputable preventive measure representative to avoid further damage to the seals and cylinders.
