Guarnizioni delle candele di accensione

Le guarnizioni delle candele di accensione sono componenti cruciali del motore di un'automobile, in quanto garantiscono la tenuta e la protezione del motore da eventuali danni. Sono soggette a diverse condizioni, tra cui temperature elevate, pressioni elevate e attrito del flusso d'aria ad alta velocità. La candela funge da guarnizione per impedire la fuoriuscita di gas caldo, che può essere dannoso per il motore e per le persone. Se la guarnizione della candela si guasta, può causare una pressione insufficiente, provocando incendi o esplosioni. Le guarnizioni per candele di alta qualità, come quelle di Linde Polymer, sono essenziali per garantire la sicurezza e le prestazioni di un veicolo.

Anelli a V

I V-Ring sono guarnizioni in gomma piena utilizzate nella vita quotidiana per evitare che polvere, umidità e impurità entrino nel paraolio, nell'alloggiamento e in altre aree. Sono economici, durevoli e possono essere utilizzati in più giri, con il massimo effetto di tenuta ottenuto regolando la forza di pressione. I V-Ring sono resistenti agli urti e alle vibrazioni e possono essere personalizzati in base alle esigenze specifiche. Il principio alla base dei V-Ring è che l'olio residuo riempie lo spazio tra il labbro principale e quello ausiliario, creando una "zona di olio intrappolato". L'aumento della pressione nella "zona di intrappolamento dell'olio" si traduce in migliori prestazioni di tenuta, poiché la sollecitazione di contatto tra il labbro ausiliario e la superficie dell'albero è maggiore.

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.

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.

Oil resistance

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.

Elasticity and resilience

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:

Comportamento meccanico

  • 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.

Proprietà fisiche

  • 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.

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.
