Background technique

The oil-fine separator is mainly used to separate lubricating oil and compressed gas. It is a vulnerable part and needs to be replaced frequently, and the price is relatively expensive. It is actually a porous filter material. Before the oil-air mixture enters the filter element, the oil droplets whose diameter is larger than the pore size of the element material will be filtered out on the surface of the element. Then, by changing the shape and size of the flow channel inside the filter material, the small-diameter oil droplets entering the filter material can be coalesced into large-diameter oil droplets on the fibers of the material under the action of inertial force, etc., and filtered out. The core of the oil and fine separator is generally made of superfine glass fiber and other materials specially developed for this purpose, which has achieved good oil removal effect, long service life and small pressure drop. The oil and fine separator core produced by professional manufacturers can reduce the oil content in the gas to 1-2ppm.

However, the current oil-fine separator needs to be disassembled and cleaned many times after use, and the lubricating oil will contain some impurities during long-term use. After the impurities block the filter material, the filtering effect will be further reduced. Therefore, an oil fine separator is urgently needed. Separator to solve the above problems.
