Study and Development of Anti-changing Working Conditions Mechanical Seal of Hot Oil Pump

The mechanical seal leakage of hot oil pump has always been an important problem for oil refineries.How to solve the leakage problem and prolong the life of mechanical seal is not only an important factor influencing the economic benefit of refineries but also very critical to the scientific research in this field.In this paper,the theory of changing working condition mechanical seal is discussed,anti-changing working condition mechanical seal is developed,and the failure of changing working condition mechanical seal is solved.It is also compared with conventional anti-exhaust mechanical seal.
