Zündkerzendichtungen

Zündkerzendichtungen sind entscheidende Bauteile in einem Automotor, die die Abdichtung des Motors und den Schutz vor Schäden gewährleisten. Sie sind verschiedenen Bedingungen ausgesetzt, darunter hohe Temperaturen, hohe Drücke und die Reibung des Luftstroms bei hohen Geschwindigkeiten. Die Zündkerze dient als Dichtung, um den Austritt von heißen Gasen zu verhindern, die für den Motor und den Menschen schädlich sein können. Wenn die Zündkerzendichtung versagt, kann dies zu einem unzureichenden Druck führen, der Brände oder Explosionen verursacht. Hochwertige Zündkerzendichtungen wie die von Linde Polymer sind für die Sicherheit und Leistung eines Fahrzeugs unerlässlich.

V-Ringe

V-Ringe sind Vollgummidichtungen, die im täglichen Leben verwendet werden, um das Eindringen von Staub, Feuchtigkeit und Verunreinigungen in die Öldichtung, das Gehäuse und andere Bereiche zu verhindern. Sie sind wirtschaftlich, langlebig und können in mehreren Runden verwendet werden, wobei die maximale Dichtwirkung durch Anpassung der Presskraft erreicht wird. V-Ringe sind stoß- und vibrationsfest und können je nach Bedarf angepasst werden. Das Prinzip der V-Ringe besteht darin, dass Restöl den Spalt zwischen der Haupt- und der Hilfslippe füllt und so eine "eingeschlossene Ölzone" entsteht. Dieser erhöhte Druck in der "Öleinschlusszone" führt zu einer besseren Dichtleistung, da die Kontaktspannung zwischen der Hilfslippe und der Wellenoberfläche höher ist.

CR V-förmige Dichtungen

CR V-ring seals are mainly used on piston rods and plungers of heavy equipment. This rubber seal provides good stability and good wear resistance, which prevents the seal ring from being squeezed into the gap, even under harsh working conditions, such as axial or radial vibration, sudden pressure, temperature changes etc., can also provide excellent sealing effect. Suitable for hydraulic oil, water, emulsion and other media.

Kraftstoffstandgeber Neopren-Dichtungen

Neoprendichtungen für Kraftstoffstandgeber sind Komponenten, die zur Abdichtung zwischen dem Kraftstoffstandssensor und dem Kraftstofftank verwendet werden. Die Hauptfunktion von Neoprendichtungen besteht darin, die Verbindung zwischen dem Kraftstofffüllstandssensor und dem Kraftstofftank abzudichten, um zu verhindern, dass Kraftstoff austritt oder externe Verunreinigungen in das Kraftstoffsystem gelangen. Sie sind oft in bestimmten Formen und Größen erhältlich, um für ein bestimmtes Modell und eine bestimmte Ausführung des Kraftstoffstandssensors und des Kraftstofftanks zu passen.

The following are some features and applications of CR rubber seals

Weather resistance

CR rubber seals have good weather resistance and can be used in outdoor environments for a long time without being damaged by ultraviolet rays, oxygen, ozone and some common chemicals.

Ölbeständigkeit

CR rubber seals have good oil resistance to common mineral oils, gasoline and lubricating oils, and can maintain their performance and sealing properties when exposed to these liquids.

Heat resistance

CR rubber seals have good heat resistance within a certain temperature range and can withstand high temperature environments without losing their elasticity and sealing properties.

Elastizität und Widerstandsfähigkeit

CR rubber seals have good elasticity and resilience and can quickly return to their original shape after compression to ensure sealing effect.

Application fields

CR rubber seals are widely used in automobiles, aerospace, electronics, machinery and other fields. They are often used for sealing automobile engines, transmission systems, hydraulic systems, air conditioning systems and other parts to ensure the normal operation of the system and prevent leaks.

CR rubber seals have a series of excellent mechanical, physical, chemical and processing properties. The following is a detailed introduction to them:

Mechanisches Verhalten

  • Strength and toughness: CR rubber seals have high tensile strength and toughness, and can withstand certain stretching and tearing forces while maintaining their integrity and sealing performance.
  • Compression deformation: CR rubber seals have good compression deformation properties and can produce moderate deformation when subjected to pressure to achieve an effective sealing effect.
  • Elastic recovery: CR rubber seals have good elastic recovery, that is, they can quickly return to their original shape after compression or deformation, ensuring the sealing effect.

Physikalische Eigenschaften

  • Density: CR rubber seals generally have a low density, making them a relatively lightweight sealing material.
  • Hardness: CR rubber seals have a wide range of hardness, and seals with different hardnesses can be selected according to specific needs to adapt to different application scenarios.

Chemische Eigenschaften

  • Oil resistance: CR rubber seals have good oil resistance to a variety of common mineral oils, gasoline and lubricating oils, and will not expand, deform or lose sealing performance due to contact with these liquids.
  • Solvent resistance: CR rubber seals also have good resistance to some solvents and chemicals and can resist their erosion and damage to a certain extent.

Here are some common general defects of CR rubber seals

  • Aging: CR rubber seals may be affected by factors such as oxygen, ultraviolet rays, ozone and high temperature during long-term use, leading to aging, hardening and loss of elasticity. This may reduce seal performance and shorten seal life.
  • Low-temperature embrittlement: CR rubber seals may undergo low-temperature embrittlement at extremely low temperatures, causing the material to become brittle, lose elasticity, and easily break. Therefore, applications in low-temperature environments require special attention to selecting suitable materials or taking other protective measures.
  • Chemical Compatibility: Although CR rubber seals have good resistance to many chemicals, they are not compatible with all chemicals. Certain chemicals can cause rubber to swell, deform, or lose its sealing properties. Therefore, adequate chemical compatibility testing is required to ensure the suitability of materials in special chemical environments.
  • Dimensional changes: CR rubber seals may undergo dimensional changes under the influence of temperature changes and pressure changes. This can cause dimensional instability in the seal, affecting sealing performance. Therefore, when designing and selecting seals, it is necessary to consider temperature and pressure changes and select appropriate materials and designs.
  • Installation and maintenance requirements: The installation and maintenance of CR rubber seals require certain techniques and precautions. Improper installation or maintenance may result in reduced sealing performance or damage. Therefore, it is recommended to follow the manufacturer’s guidance and recommendations during installation and maintenance.
