Mechanical Face Seals - Heavy Duty Seals

机械端面密封件 是专为极端严苛的旋转应用环境设计的密封件，极为耐磨，并且能防止外部粗糙研磨介质侵入 。也被称为 端面密封件, 重载密封件, 永久密封件,浮动密封件, 双锥密封件 或复曲面密封件. Mechanical Face Seals or heavy duty seals are specifically engineered for rotating applications in extremely arduous environments where they withstand severe wear and prevent ingress of harsh and abrasive external media. A Mechanical Face Seal is also known as Heavy Duty Seal, Face Seal, Lifetime Seal, Floating Seal, Duo Cone Seal, Toric Seal

有 两种不同类型的机械端面密封件:

• DO型 是普通的形式，使用O形圈作为第二道密封元件。Type DO is the most common form that uses an O-Ring as a secondary sealing element
• DF型 以具有菱形截面的弹性体作为第二道密封元件，而不是用O形圈。Type DF has an elastomer with a diamond-shaped cross section as a secondary sealing element
  instead of the O-Ring

两种类型的密封件都是由2个金属密封圈组成的，它们面对面地装在单独的腔室内，弹性体元件使密封件在腔室内对中。 机械端面密封一个为静环在腔室中保持静止，另一个为动环绕配合端面旋转. Both types consist of two identical metal seal rings mounted in two separate housings face-to-face on a lapped seal face. The metal rings are centered within their housings by an elastomer element. One half of the Mechanical Face Seal remains static in the housing, while the other half rotates with its counter face.

应用Applications

机械端面密封主要用作轴承密封，用于工程机械及工厂工作条件恶劣、磨损严重的工况中。 Mechanical Face Seals are predominantly used for sealing the bearings in construction machinery or production plants operating under extremely arduous conditions and subject to severe wear.

包括:

• 履带式车辆，例如挖掘机和推土机 Tracked vehicles, such as excavators and bulldozers
• 输送机系统 Conveyor systems
• 重型卡车 Heavy trucks
• 轮轴 Axles
• 隧道盾构机械 Tunnel boring machines
• 农业机械 Agriculture machines
• 采矿机械 Mining machines

机械端面密封在通用机械中已被成功应用于 齿轮箱、混料装置、搅拌机、风力发电站及其它工况类似 或 期望在生命周期内免维护的场合。 Mechanical Face Seals are proven for use in gearboxes, mixers, stirrers, wind-driven power stations and other applications with similar conditions or where maintenance-free lifetime sealing is expected.
