发动机油封是存放发动机时防止其锈蚀的主要技术措施。目前国内涡扇发动机试车后的油封工作一般在试车台上进行,大量占用了试车台架的使用时间和起动机的使用寿命,降低了试车效率。本文通过对发动机油封技术的研究、分析,制定出该发动机的带转油封技术方案来解决这一问题。发动机试车结束后,在台下的油封间内利用液压马达带转的方式来代替涡轮起动机,建立小型的液压站动力源进行油封,从而解决了试车台架紧张和起动机寿命短等问题。
髮動機油封是存放髮動機時防止其鏽蝕的主要技術措施。目前國內渦扇髮動機試車後的油封工作一般在試車檯上進行,大量佔用瞭試車檯架的使用時間和起動機的使用壽命,降低瞭試車效率。本文通過對髮動機油封技術的研究、分析,製定齣該髮動機的帶轉油封技術方案來解決這一問題。髮動機試車結束後,在檯下的油封間內利用液壓馬達帶轉的方式來代替渦輪起動機,建立小型的液壓站動力源進行油封,從而解決瞭試車檯架緊張和起動機壽命短等問題。

The engine oil seal is the main technical measures to prevent the corrosion of every parts and components when storing the engine. At present, the oil seal working of engine is on the test bench after test run qualified, so it will hold-up time in quantity of the test bench, meanwhile, it will reduce the service life of the starter, leading to bring down the test efficiency. In this article, through research and analysis of the engine oil seal technology, the project of take turn to oil seal technology is worked out to solve this problem. After the engine test run, do not oil seal on the test bench, but remove the engine from test bench directly, afterwards, at the oil seal chamber, using of hydraulic motor turns instead of turbine starter, establishing a small hydraulic station as the power supply to oil seal, so as to solve problems such as test bench shortage and too short starter service life.
