Description
Technical field
The present invention relates to a kind of filter cleaner, particularly a kind of filter core of automobile fuel oil filter.
Background technique
Automobile fuel oil filter is all adopt filtering type filtering.
In early days, the filter core of gasoline filter has tinsel chink type, metal screen formula, nylon cloth, porous ceramics formula etc.The feature of tinsel chink type, metal screen formula, nylon cloth is reliable operation, long service life, but smoothing effect is poor, complex structure, manufactures and cleaning inconvenience, is gradually eliminated; The feature of porous ceramics formula is that structure is simple, and filtering usefulness is high, but maintenance washes is more difficult, not easily cleans, and working life is not long, and application is less at present.
The material for core of diesel-oil filter has cotton yarn, nylon cloth, felt, wire etc.They are good by performance, long service life, but the shortcoming such as ubiquity filtering efficiency is low, complex structure, cost are high, maintenance is inconvenient, be also eliminated.
At present, gasoline filter and diesel-oil filter all generally adopt micropore paper filter core.Due to paper filter core have good by performance, smoothing effect good (filtering efficiency >=99.6%), cost is low, maintain the advantages such as easy, is thus used widely.What domestic and international use was maximum is disposable filter filter core, and it is made up of parts such as filtration paper cylinder, central network cylinder, upper and lower covers, and the upper and lower covers made by steel plate with tackiness agent, filtration paper cylinder and central network cylinder bond.The operations such as wherein filtration paper cylinder need make folding tube after phenolic resin process, upper and lower covers needs punching press, the deep processing of central network cylinder, technique is loaded down with trivial details, and structure is more complicated, often has degumming phenomenon, and working life is short.For above-mentioned degumming phenomenon, upper and lower covers adopts epoxide resin material to make by some MANUFACTURER, and resin is poured in mould, and allow its spontaneous curing together with filtration paper cylinder, central network cylinder combine together, although overcome degumming phenomenon, other shortcoming still exists.After paper filter core blocking, cleaning is more difficult, must more renew cartridge.Disposable paper filter core filter cleaner, the replacement cycle is generally 10000 kilometers.
Summary of the invention
