Primærpakninger

Primærpakninger, also known as primary seals, are critical components in many mechanical systems. Their main function is to prevent leakage between two mating surfaces that are intended to contain a fluid or gas. This containment is essential for the proper operation and safety of various equipment, from engines and pumps to pipelines and hydraulic systems. The design and material of a primary seal are chosen based on factors such as the operating pressure, temperature, the type of fluid or gas being contained, and the chemical environment. Common types of primary seals include O-rings, gaskets, lip seals, and mechanical seals. O-rings are simple toroidal seals that rely on compression to create a seal. Gaskets are typically made of softer materials and are compressed between two rigid surfaces. Lip seals feature a flexible lip that maintains contact with a rotating or reciprocating shaft. Mechanical seals are more complex and use precisely lapped faces to create a seal. The integrity of a primary seal is paramount. A failure in a primary seal can lead to loss of product, environmental contamination, potential safety hazards, and costly downtime. Therefore, their selection, installation, and maintenance are crucial aspects of engineering and maintenance practices. The effectiveness of a primary seal is often verified through pressure testing or visual inspection.
