Pneumatic seals mainly contain fluids such as compressed air and steam. Materials with advanced properties, which provide the best balance between friction loads, the form of fluids, and the effects of temperature and pressure, are used to produce pneumatic seals.
Seals play a crucial role in the hydraulic cylinders and systems’ operation, design, and service life. The Piston Seals’ purpose is to provide a leak-proof device, wear and tear resistance, high and temperature resistance, low friction, and easy installation. Pneumatic Seals Suppliers in Dubai choose the piston seal material based on their application to restrict the properties needed for optimizing the device’s functioning.
Piston seals for hydraulic or pneumatic cylinders are usually used for shutting gaps or sealing joints. Based on the devices’ application, hydraulic piston seals come in various sizes and materials. In general, piston seals on the surface are soft and smooth, non-metallic rings that sit in the groove to form a seal assembly to isolate fluid in reciprocating motion applications. For fluid power to be transformed into linear motion without any losses, its use is critical.
Generally, pneumatic seals are made of several materials such as polyurethane, rubbers. There are dynamic hydraulic piston seals called rod seals on the hydraulic cylinder’s inner diameter that are exposed to motion along with the piston.
General Guidelines for proper installation –
Create Working Space
Make a dedicated work area for seals to be mounted. The comfort of easy installation is provided by taking out hydraulic cylinders in an open and suitable room.
Remove the Old Seal
Ensure that the old seal is removed without scratching the surface around the seal before installing the new piston seal. Removal can be achieved reasonably rapidly with the aid of a seal pick.
Clean the Cylinder Parts
Clean the cylinder sections thoroughly to ensure that no chips, debris, and other foreign particles remain in the groove of the cylinder. Furthermore, different parts’ cleaning will ensure the seal’s long-lasting efficiency to perform its purpose optimally. The sharp edges need to be debarred or chamfered before seals are inserted into the grooves or tube to ensure smooth insertion of the pneumatic seals into the cylinder.
Close Inspection Parts
It is essential to carry out a close inspection of the pieces, especially for parts that require sealing for any scoring marks or cuts. Seals may be damaged by scratches or scoring marks on the cylinder sections’ surface, leading to leakage in the device. It will take a long time to avoid installing pneumatic seals with sharp edges to ensure the seal’s existence remains intact.
Place The Seal In The Right Position.
Pneumatic seals are subject to high pressure, including the seal’s proper seating in the cylinder groove. While the seal is installed, it must be ensured that the seal is correctly seated in its place.
Use Right Lubricants
Lubricants and oil compatible with seals must be used with designated lubricants or greases to install seals on the cylinder. The same lubricants used in the manufacture of seals should be used for installation.
Do Not Use Sharp-Edged Tools.
To mount the seals on the cylinder, do not use any sharp-edged tools, as they could damage the seal during installation. Using blunt and designated tools for the building is recommended. There are tools specifically designed to install the seal on the cylinder that is available on the market. The cylinder must contain a lead-in chamfer while installing the seals. And if it is not available, then consider using an installation sleeve. inserting seals; always consult the pneumatic Seals Suppliers for detailed information.
