摘要

舱壁密封件是关键的安全部件,它可以阻止井筒穿过舱壁位置的水密隔舱之间的水淹。大多数舱壁密封技术是基于一种接触方式,密封材料总是与旋转轴接触。径向和轴向运动、振动、轴对中错误、舱壁对中错误、密封方向和气压差都可能导致这些接触舱壁密封过早磨损或失效。如果对密封进行适当的检查和维护,这种磨损将导致大量的维护成本,如果密封没有得到适当的维护,则可能导致灾难性的故障。本文将介绍一种新的非接触和非旋转舱壁密封设计,它只在存在水的情况下起作用。

Non-Contacting Water Activated Bulkhead Seals: Improved Safety and Reduced Costs
Bulkhead seals are critical safety components which stop progressive flooding between watertight compartments at the location of the shaft penetration through the bulkhead. Most bulkhead seal technology is based on a contacting approach where sealing materials are always in contact with the spinning shaft. Radial and axial shaft motion, vibration, shaft mis-alignment, bulkhead mis-alignment, seal orientation and air pressure differentials can cause these contacting bulkhead seals to pre-maturely wear or fail. This wear then leads to substantial maintenance costs if the seals are properly inspected and maintained or can lead to catastrophic failure should the seals not be properly maintained. This paper will present a new non-contacting and non-rotating bulkhead seal design that only activates in the presence of water.
