Tiivistemännät

Tiivistemännät, often translated as seal pistons or sealing pistons, are specialized components used in various fluid power and sealing applications. Their primary function is to create a seal between a moving surface and a stationary surface, preventing leakage of fluids or gases. In hydraulic and pneumatic cylinders, tiivistemännät are integral parts of the piston assembly, working in conjunction with cylinder walls to contain pressurized fluid or air.

These components are typically manufactured from materials such as rubber, polyurethane, or specialized plastics, chosen for their elasticity, chemical resistance, and wear properties. The design of a tiivistemännät can vary significantly depending on the specific application. Common designs include O-rings, U-cups, and more complex multi-lip seals, each offering different sealing characteristics and pressure capabilities.

The performance of tiivistemännät is crucial for the efficiency and longevity of fluid power systems. Factors like friction, temperature, and the type of fluid or gas being sealed all influence the choice of material and seal design. Proper installation and maintenance are essential to ensure optimal sealing performance and prevent premature failure. In some advanced applications, tiivistemännät may incorporate features like anti-extrusion rings to enhance their performance under high pressure conditions. They are a fundamental element in maintaining the integrity of pressurized systems.
