However, during use, the oil is often mixed with moisture and air, and these impurities will seriously affect the performance of the oil, causing equipment to ignite and malfunction frequently.

[0003] The existing devices for removing moisture and air from oil still have some shortcomings in actual use:

[0004] Traditional methods of removing moisture and air from oil mostly rely on natural sedimentation, filtration or centrifugal separation, but these methods are often inefficient and incomplete, and cannot meet the needs of modern industry for high-purity and high-efficiency oil treatment. In addition, traditional oil injection processes are difficult to completely remove air from workpiece cavities with complex internal cavities and many pipes. Utility Model Content
