tätningshölje

Tätningshölje is a Swedish term that translates to "sealing housing" or "seal housing" in English. It refers to a protective enclosure or casing designed to prevent leakage or ingress of substances, typically fluids or gases, in mechanical systems. Tätningshöljen are crucial components in a wide range of applications where maintaining a seal is essential for the proper functioning and longevity of machinery and equipment.

The primary function of a tätningshölje is to contain a sealing element, such as a gasket, O-ring, or mechanical seal, in its correct position and under the necessary compression. This ensures that the seal effectively prevents unwanted material transfer between different parts of a system. For example, in a pump, a tätningshölje would house the mechanical seal, preventing the pumped fluid from escaping into the environment or preventing external contaminants from entering the pump.

Tätningshöljen are typically manufactured from robust materials like metals (steel, aluminum) or durable plastics, chosen based on the operating conditions, such as temperature, pressure, and chemical exposure. The design of a tätningshölje is critical; it must provide a stable mounting surface for the sealing element and often incorporates features for secure attachment to the surrounding components. Precise manufacturing is key to ensure that the hölje does not interfere with the sealing function or cause premature wear of the seal itself.
