Description

technical field

[0001] The invention relates to a purification device, in particular to a high-precision centrifugal oil purification machine, which is applied in the fields of aviation, aerospace, metallurgy, petroleum, chemical industry and the like. Background technique

[0002] Petroleum-based liquids are often used to lubricate components and hydraulic systems in aircraft, natural gas transmission pump stations, road construction equipment, engines, and various machine tools. Working liquid in the system, diesel fuel in summer, etc. When impurities are mixed into the petroleum-based fluid, it will seriously affect the service life and reliability of the lubricated components and hydraulic system.

[0003] At present, there is a centrifugal oil purifier that uses the principle of physical centrifugation to filter oil. The oil pump is used to drive the oil into the centrifuge. The oil enters the rotating part of the centrifuge, and the impurity particles are deposited in...
