Dust seals primarily serve to prevent external dust, debris, and other contaminants from entering the system's interior. They function like dedicated guardians, maintaining cleanliness within the device. For instance, in hydraulic cylinders, dust seals block particulate matter from entering the cylinder with the piston rod's movement, safeguarding components like pistons, seals, and cylinder walls from wear and damage, ensuring optimal operation and longevity.
Piston seals are crucial for preventing leakage of working fluids between the piston sides, ensuring the system can establish and maintain required pressure for stable performance. In a hydraulic system, proper piston seals allow fluid to flow along designated paths, facilitating piston motion and preventing high-pressure oil from escaping to the low-pressure side, impacting efficiency and performance. Additionally, these seals must exhibit excellent corrosion resistance for extended use under various conditions.
Oil seals are essential for sealing rotating shafts and preventing the leakage of lubricants or other fluids through gaps between the shaft and housing. They also safeguard against external contaminants like dust and moisture. In automotive engines, oil seals play a vital role in sealing critical components like crankshafts, ensuring the engine's lubrication system remains intact and preventing external pollutants from compromising engine operation. The seal integrity directly influences the device's reliability and durability.
