Rotary Rod Seal/ Rotary Rotomatic Seal/ Rotary Swivel Seal

Rotary seals, also known as radial shaft seals or lip seals, are essential components used in rotating machinery to prevent the leakage of fluids and to protect the moving parts from external contaminants. They are commonly used in applications such as pumps, motors, gearboxes, and engines.

Characteristic

1. Function: The primary function of a rotary seal is to create a barrier between the rotating shaft and the surrounding environment. It prevents the escape of lubricants, such as oil or grease, and prevents the entry of contaminants, such as dust, dirt, or water.

2. Construction: Rotary seals typically consist of an outer metal case, a flexible sealing lip made of elastomer material, and a garter spring for maintaining proper sealing pressure. The sealing lip makes contact with the shaft and creates the dynamic sealing effect.

3. Material Selection: The choice of material for rotary seals depends on the specific application requirements including fluid compatibility, temperature range, pressure, and speed. Common materials include nitrile rubber (NBR), fluoroelastomer (FKM), silicone rubber (VMQ), and polytetrafluoroethylene (PTFE).

4. Design Considerations: When selecting a rotary seal, considerations should be given to factors such as shaft speed, operating temperature, pressure, shaft size, and the nature of the fluid being sealed. These factors will help determine the appropriate seal design, size, and material for optimal performance and longevity.

5. Installation and Maintenance: Proper installation and maintenance are essential for the effective performance of rotary seals. The shaft and seal housing should be clean and free from burrs or damage. Lubrication may be required during installation, and regular inspection and replacement of worn or damaged seals are recommended.

6. Types of Rotary Seals: There are various types of rotary seals available to suit different applications. Some common types include radial shaft seals (single lip or double lip), metal-cased seals, cassette seals, and split seals. The selection of the seal type depends on factors such as operating conditions and space limitations.

7. Performance and Efficiency: Well-designed and properly installed rotary seals can significantly improve the performance and efficiency of rotating machinery. They help reduce friction, minimize wear on components, and prevent lubricant leakage, therefore extending the service life of the equipment.

Rotary seals play a vital role in maintaining the integrity of rotary systems by preventing fluid leakage and protecting against contamination. Careful consideration of the application requirements and proper selection and installation of rotary seals can ensure optimal performance and of rotating machinery.

The choice of Rotary Seal determines the operating efficiency and operating cost of the equipment. We can provide different types of oil seals. Welcome to consult.
