Choix du joint d'huile :
Similar to the selection principle of other seals, the selection of China High -pressure Oil Seal must also select the type and material of the oil seal according to the sealing medium and working conditions. Working conditions mainly consider working pressure, working line speed and working temperature range.
Lors de la sélection du matériau du joint d'huile, la compatibilité du matériau sur le milieu de travail, l'adaptabilité de la plage de température de travail et la capacité de suivre l'axe de rotation à grande vitesse de l'axe de rotation. La température de la marge de la lèvre est supérieure à la température du milieu de travail à 20 ~ 50 ° C pendant le milieu de travail, et vous devez faire attention lors de la sélection du matériau du joint d'huile.
Dans les mêmes conditions de diamètre, la capacité du joint d'huile fabriqué en différents matériaux à s'adapter à la vitesse de rotation de la surface de l'axe est différente. La relation est illustrée dans la figure ci-dessous. La plage de vitesse de ligne utilisée dans les joints d'huile est généralement inférieure à 15 m/s.
La pression d'utilisation des joints d'huile ordinaires ne dépasse généralement pas 0,05 MPa. Lorsque la pression de travail dépasse cette valeur, un joint d'huile résistant à la pression doit être utilisé.
The working range of China High -pressure Oil Seal is related to the material used for oil seal: the material is -40 ~ 120 ° C at the time of the Dingqing rubber (NBR), the Alek rubber (ACM) -30 ~ 180 ° C, and the fluorine rubber (FPM) -25 ~ 300 ° C.
The stable China High -pressure Oil Seal is an innovative sealing solution designed for high pressure applications. Widely used in hydraulic, pneumatic, automotive engineering and other industries.
Stable China High -pressure Oil Seal Overview:
Plate frame china high temperature oil seal is a sealing device to prevent fluid leakage in high pressure applications. It consists of a sheet metal skeleton supporting a sealing lip made of elastomeric material. The sealing lip is in direct contact with the fluid and forms a barrier against fluid leakage.
Working Standards:
The working principle of the stable China High -pressure Oil Seal is fairly simple. When the seal is installed in a hydraulic or pneumatic system, fluid pressure acts on the sealing lip, causing it to deform and press against the mating surface. This creates a high pressure seal that prevents fluid leakage.
stable China High -pressure Oil Seal Pros:
High pressure resistance: The plate skeleton design provides excellent stability and rigidity, enabling the seal to withstand high pressure environments without deformation or failure.
Low Friction: The elastomeric material used in the seal lip has low friction properties to reduce wear and extend the life of the seal.
Chemical Resistance: Sealing lips are made from a variety of elastomeric materials, including NBR, FKM and EPDM, which offer excellent chemical resistance to a wide variety of fluids and chemicals.
EASY TO INSTALL: Panel skeleton design allows for easy installation without special tools or equipment.
Material:
The plate skeleton is made of high-strength steel or other durable materials that can withstand high pressures and extreme temperatures.
Seal lips are typically made of high performance elastomers such as Nitrile rubber or fluorocarbons that can withstand the harsh environment of high pressure applications.
Design Features:
The plate skeleton design provides a rigid structure that can withstand high pressures without deformation or failure.
The seal lip is designed to provide a tight seal on the shaft or cylinder to prevent fluid leakage.
Seals can also include additional features such as dust lips or auxiliary sealing lips to provide additional contaminant protection and improve sealing performance.
Performance specifications:
For china high temperature oil seals are designed to withstand pressures up to 10,000 PSI or higher, depending on the specific application.
They can operate over a temperature range of -40°C to 200°C, depending on the material used.
The seal lips are designed to provide low friction operation and long service life, even under high pressure conditions.
Installation and Maintenance:
High pressure oil seals for plate skeletons should be installed using proper tools and techniques to ensure proper fit and seal.
Periodic maintenance is recommended to inspect seals for wear or damage and replace as needed.
Proper lubrication is also important to ensure proper operation and to prevent premature seal failure.
stable China High-pressure Oil Seal application:
Plate frame high pressure oil seals are widely used, including:
Hydraulic system: Plate skeleton high pressure oil seals are often used in hydraulic systems to prevent fluid leakage and maintain system integrity.
Pneumatic Systems: Seals are also used in pneumatic systems to prevent air leakage and maintain system efficiency.
Automotive Engineering: The seal is used in a variety of automotive applications including power steering, transmissions and shock absorbers.
Industrial Applications: The seal is used in a variety of industrial applications including heavy machinery, mining equipment and construction equipment.
In conclusion:
To sum up, the plate frame china high temperature oil seal is an essential part in high pressure applications. Its innovative design provides excellent stability, rigidity and high pressure resistance, making it ideal for a wide variety of industries. With its low friction, chemical resistance and ease of installation, it is a reliable and cost-effective solution for preventing fluid leakage and maintaining system integrity. As an Fabricant de joints d'huile, KNT provides High -quality oil seals for selection.

China High -pressure Oil Seal are precision components. Improper assembly and storage affect the performance of use. The storage oil seal should prevent dust, rust, and deformation. The oil seal cannot be directly illuminated by the sun, and it cannot be squeezed. The oil seal installed on the shaft should prevent the shaft and oil seal stroke rust. Pay attention to the following matters when installing and disassembling oil sealing:
(1) Lors de l'installation du joint d'huile, appliquez de l'huile ou de l'huile de graissage.
(2) Lors de l'installation du joint d'huile, il est nécessaire de faire en sorte que le bord de la lèvre soit face au côté de l'huile scellée. Ne l'assemblez pas à l'envers.
(3) Lorsque le joint d'huile est chargé dans les trous du siège, il doit être poussé à l'aide d'un outil dédié pour éviter que la position ne s'enfonce.
(4) The threads, key slots, bonds, etc. of the lip margin passed by the lip seal should be adopted to prevent lip margin damage and assemble with a dedicated tool.
