液压密封件 –提高性能

液压应用对于密封件是严峻挑战。液压密封件不仅要防止液体从油缸中泄漏,还要能承受油缸中 高压,极端的温度和侧向力的作用。 在这些应用中, 液压密封件的功能远不止防止泄漏。

液压油缸密封件:高性能和耐用性

液压系统的密封是由一系列专门的密封件组合来实现的。活塞杆密封 件防止液体从油缸内部泄漏到外部,同时,液压活塞密封件防止液体从缸头流出。 这使压力在活塞的一端积聚,从而让油缸得以伸缩。
耐磨环的功能是为液压油缸的活塞和活塞杆提供导向和支承作用,以及吸收侧向负载。同时,可以防止油缸运动部件间的金属接触,优化密封系统性能。
防尘圈和耐磨环安装在液压缸内,当活塞杆缩回系统时,用于刮除活塞杆上的脏物,杂质颗粒,碎屑和水分等,以防止它们污染液压介质。同时可防止它们损坏耐磨环,密封件和其他元件。

Hydraulic scraper
Innovative materials for Hydraulic Seals Hydraulic Seals from Trelleborg Sealing Solutions are the first choice when it comes to sealing a high-performance cylinder.
Our proprietary materials, such as Polytetrafluoroethylene (PTFE) based Turcon® or polyurethane (PU) based Zurcon® ensure maximum durability and performance with minimum maintenance.

Specially engineered – extraordinarily efficient

Hydraulic systems are usually sealed with a complex configuration of high performance seals. Our Hydraulic Seals products range includes O-Rings and a number of innovative Seals designed for applications in hydraulic cylinders, such as the spring-energized Turcon® Variseal®, O-Ring engergized Turcon® Stepseal®2K, Zurcon® polyurethane U-Cup RU9 and many more.

Discover our Hydraulic Cylinder Seals product range
Trelleborg Sealing Solutions offers a wide range of Seals for all applications within hydraulic cylinders:
Rod seals and piston seals prevent leakage of fluid from cylinders and stop pressure buildup.

Wear rings guide the piston and piston rod preventing metal to metal contact.

Scrapers or Wipers are Seals which prevent external media from entering the cylinder.
