In order to ensure the normal operation of oil filling equipment such as steam turbine and power transformer,and reduced the micro amount of water mixed in oil filling equipment,the superhydrophobic-super lipophilic organic-inorganic hybrid membrane was prepared by using nano-SiO2 particles,epoxy resin and filter membrane.The relationship between initial water content,separation times,temperature and oil-water separation efficiency was studied.The physical and chemical properties of the membrane were investigated,and the field application of industrial overhaul oil and transformer oil to be overhauled was carried out by building a groups of membrane filters.The results shown that increasing the initial water content and separation times can improve the oil-water separation efficiency.The temperature had little effect on the separation efficiency,and the filtration speed should be kept in a certain range.The mechanical properties of the film were improved,and it had scour resistance and stability.After filtering the waste transformer oil,the water content decreased rapidly and the particles in the oil can be basically completely removed.
