| Summary: | 碩士 === 大葉大學 === 機械工程研究所 === 89 === The sealing system plays an important role in the performance of hydraulic and pneumatic transmission equipments .Whether in automotive,chemical and process,manufaturing, marine or power generation industries,the working environment of the sealing system become more and more demanding.Operational conditions with higher power ,temperature and working speed are expected.Adaptability numbers of lubricants and greases,greater reliability,and extensed running also post great challenges.
Hence,it is important for engineers to design an optimal seal that can prevent leakage,corrosion,inflammable or incom-patible fluid under high pressure or temperature on continuous running machinery in a sterile,explosive or other critical environment.
This report was based on Design Of Experiment (DOE ) and Computer Aide Engineering (CAE) experiments in research of pressure oil seals.
Relevant data were collected from the reactions of seals under different pressure environments, so that important parameters and factors can be found.This research has come to the conclusion as following three findings:
1.Seals that are bounded with PTFE can withstand stronger pressure than seals that are made from regular material.
2.Air side of lip angle has tremendous influences on the seal’s ability to stand pressure.
3.Response Surface Model can be obtained by gathering the para-meters from thickness and length of the seal lip.
It is hoped that the current research will be contributive in designing seals.
