摘要
Abstract
Taking the rotary seals and lubrication system of a High Ice-Class podded propulsion main shaft as the research subject,a test platform capable of simulating authentic polar conditions was designed and constructed.Six typical operational scenarios were tested,including static conditions,variable rotational speeds,variable water depths,variable temperatures,pressure fluctuations,and shaft eccentricity.Through real-time monitoring of seal friction torque,air consumption,and leakage conditions,the operational stability and response characteristics of the sealing system were comprehensively evaluated.The results demonstrate that the developed sealing system achieves continuous two-hour operation without oil-water leakage under all tested conditions,exhibiting stable sealing performance.The seal opening pressure exhibits a linear relationship with water depth.Temperature increases significantly elevate friction torque and air consumption,while shaft eccentricity has a negligible impact on seal opening.This study verifies the synergistic performance of the sealing and lubrication systems,providing experimental evidence and theoretical support for optimising polar sealing system design and engineering applications.关键词
