- The Importance of Rotavator Oil Seal A Comprehensive Overview
- Another important factor is the quality of the oil used in the engine. Oils with low viscosity or poor quality can cause the main bearing oil seal to fail prematurely. Therefore, it is essential to use high-quality oils that are specifically formulated for use in engines. These oils have the right balance of viscosity and additives to ensure optimal performance and longevity of the oil seal.
Maintenance and Replacement
- Moreover, their importance extends into the aerospace sector where they are utilized in aircraft engines, fuel systems, and cabin interiors to maintain structural integrity and safety. Their ability to withstand harsh environmental conditions, such as extreme temperatures and pressure changes, makes them indispensable in this field.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
In this blog, we attempt to highlight what are Oil Seals and the various Rotary Shaft Seals including Mechanical Face Seals, Water Pump Seals, Gland Packings, and V-Seals that are readily available.
FKM or FPM, which is in well-known brand Viton™, can withstand higher liquid temperatures of up to 180 ˚C. FKM is highly resistant to strong acids and bases, as well as to synthetic oils and greases. Glycol-based oil and grease, however, can also damage FKM.
A) Shaft runout
As shown in Figure 8, shaft runout is defined as being twice the eccentricity between the shaft center and center of shaft-center rotation trajectory.
• Rubber material
• Seal type, etc.
The performance of these seals depends to a large extent on a suitable unit load being maintained at the seal-shaft interface. These seals withstand a pressure of 15PSI and their working depends on parameters like shaft diameter, shaft speed, working temperature, service conditions, etc
