Description
[technical field]
The utility model relates to the automobile filter apparatus field, is specifically related to a kind of screw type gasoline filter.
[background technique]
The effect of screw type gasoline filter is with moisture in the gasoline and impurity filtering, and gasoline gets into through oil inlet pipe in the sediment bowl of filter cleaner under the effect of petrol pump during engine operation; Because this moment, volume became big; Flow velocity diminishes, and than the bottom that the heavy water of oil and impurity particle just are deposited in cup, light impurity flows to filter core with gasoline; And the gasoline of cleaning flows out through oil pipe from the inside that the micropore of filter core oozes people's filter core then.
At present; The filter paper that the screw type gasoline filter is adopted mostly is only to possess the filter paper that filters solid impurity; Though this gasoline filter paper filters solid impurity, and is powerless to the separation of moisture in the gasoline, and not only contain solid impurity in the gasoline usually; Also contain other impurity such as moisture, it is often not good to rely on the mode of conventional natural sedimentation to filter the effect of moisture.Therefore although present widely used BBG is strict more to petrol-injected control, the quality requirements of gasoline is improved day by day, the moisture that contains in the gasoline then is difficult to through existing screw type gasoline filter filtering.In a single day moisture in the gasoline get into motor, promptly possibly cause following infringement to motor:
1, makes the precision pair of motor power supply system be in the semi-dry friction state, cause the strong wear of precision pair.
2, cause that fuel feeding is the corrosion of smart even part and cylinder.
3, dissolve some mechanical admixture, for example salt is difficult for being removed by filter after salt is dissolved, causes the corrosion of oil supply system precision pair and cylinder.
