英文摘要：

Based on working principle, structure and composition features of the vacuum oil filter, the general key problems in different conditions of the equipment are analyzed and the corresponding ideas on improving its system and structure are proposed to promote oil purification effect and efficiency of traditional oil filtering equipment. A vacuum oil filter is general equipment for oil purification, however, the dynamic property of its working process and deep purification quality still need to be deeply researched and discussed.
