Description
Technical field:
The utility model relates to a kind of diesel-oil filter of controlling function with liquid level, belongs to filter cleaner technical field.
Background technique:
Filter cleaner is widely used in internal-combustion engine, automobile, engineering machinery, air-conditioning, generator and other industrial field, it by the filtration of medium (as air, machine oil, fuel oil etc.) with reach protection associated equipment object.
2010, the whole nation only vehicle complete vehicle output just reached more than 1,800 ten thousand, clearly, as the filter cleaner of easily damaged parts, had equally very huge market.
Recent years, along with emission request progressively improves, diesel-oil filter is also more and more higher by the precision of filter paper.Companion what come is that the starting difficulty problem of vehicle manifests, particularly all the more so concerning powerful diesel-oil vehicle.
Referring to Fig. 1, existing diesel-oil filter is generally comprised of parts such as filter tank 1, fuel oil fitering element parts 2, the close board component 3 of screw thread, seal ring 4, springs 5.Wherein fuel oil fitering element parts 2 are core components of realizing filter cleaner filtering function.
Along with Abgasgesetz is more and more stricter, cleaner filter paper filter precision is also unavoidably more and more higher, existing diesel-oil filter, when its (being mainly oil and water seperator) is arranged on the front end (i.e. " oil absorbing end ") of high-pressure service pump, in practical work process, according to Henry law, air in diesel oil can constantly be separated out, then be gathered in the dirty oil end (i.e. space between " filter tank and fuel oil fitering element parts ") of diesel-oil filter, along with air is more and more, dirty oil end diesel oil pasta declines gradually, until be reduced to when the inside and outside liquid level height of fuel oil fitering element parts is poor to match with its first bubble point pressure value.Once engine shutdown, due to the easy fluidity of fluid (diesel oil is also a kind of fluid), the diesel oil in oil pipe flows out from pipe, flows in diesel-oil filter, causes the pasta in filter tank to rise, and is full of again air in oil pipe simultaneously.Thereby again during ato unit, there is difficulty in starting phenomenon.
Model utility content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of diesel-oil filter of controlling function with liquid level.
The diesel-oil filter of controlling function with liquid level of the present utility model, it comprises filter tank, fuel oil fitering element parts, the close board component of screw thread, seal ring, spring, liquid level control cover and upper end cap; Fuel oil fitering element parts are arranged on the inside of filter tank, the close board component of screw thread is arranged on the top of filter tank, spring is arranged on the bottom of fuel oil fitering element parts, the top of fuel oil fitering element parts is provided with upper end cap, the upper surface of upper end cap is provided with one group of vent slot, liquid level is controlled the top that cover is arranged on fuel oil fitering element parts, and is provided with seal ring between liquid level control cover and fuel oil fitering element parts and between liquid level control cover and the close board component of screw thread.
The beneficial effects of the utility model are: its novel structure; upper surface at the upper end cap of fuel oil fitering element parts is opened one group of vent slot; be equipped with functional component---" liquid level is controlled cover "; under the two acting in conjunction; liquid level while realizing real work in diesel-oil filter is controlled in the lower end surface that liquid level is controlled cover all the time; thereby after shutdown, there will not be the phenomenon that refills air in oil pipe, guaranteed that motor is easy to starting.
