Tätningshöljen

Tätningshöljen are components used in various mechanical systems to prevent the ingress or egress of fluids, gases, or contaminants. They function by creating a seal around moving or static parts, thereby maintaining the integrity of the system. The design and material of a tätningshölje are crucial for its effectiveness and are determined by the specific application, including the operating pressure, temperature, speed of motion, and the nature of the media being contained or excluded.

Commonly, tätningshöljen are found in applications such as pumps, engines, hydraulic cylinders, and rotating shafts. They can be made from a range of materials, including rubber, plastic, metal, and composite materials, chosen for their resistance to wear, chemical compatibility, and ability to maintain flexibility or rigidity as required.

The types of tätningshöljen vary widely. For instance, rotary shaft seals, often referred to as oil seals or lip seals, are designed to seal rotating shafts. Static seals, such as O-rings or gaskets, are used where there is no relative motion between the surfaces being sealed. In some cases, a tätningshölje might incorporate multiple sealing elements or a complex geometry to achieve a higher degree of sealing performance or to accommodate specific environmental conditions. The proper selection and installation of a tätningshölje are essential to prevent leaks, reduce friction, and extend the operational life of the equipment.
