Description

Do wet combined type air-strainer

One, affiliated technical field:

The utility model belongs to the single cylinder that is installed on the agricultural transportation vehicle or the air-strainer on the multicylinder engine.

Two, background technique:

Air-strainer is one of crucial annex that ensures the normal ride quality of motor, the quality of its filter makings amount is to the power of motor, direct influence is arranged working life etc., the employed air-strainer of existing transport vehicle generally is divided into dried master mode and oil immersion (bath) formula two big classes, it all is through simple dried master mode filter element filtering or just filters through simple oily filter formula, its poor filtration effect, working life is short, effect is poor, have a strong impact on the working life of motor, on the locomotive that is operated in windy and dusty area, be influenced by the adverse circumstances, its filtering effect is poorer, has caused the early stage damage of numerous vehicles.In order to improve the filtering effect of air, someone once used two dried master mode filter cleaner series connection, though can make air cleaning like this some, but the stroke of air in filter is very long, and air is blocked, and the speed that enters generator slows down, cause fuel oil insufficient, not only waste fuel, cause environmental pollution, also influenced the power of motor.

Three, summary of the invention:

The utility model is exactly to solve now with the problems referred to above that exist in the technology, and a kind of good filtration effect, long service life, the fluent dried wet combined type air-strainer of air are provided.

For addressing the above problem, technical solution of the present utility model is: a kind of combined type air-strainer that wets of doing, it comprises upper and lower shell, suction tude, steam outlet pipe, dried master mode filter core, the equal sheet of air, oil removal retaining soil dish, thread filter core, pure machine oil, laying dust cap; The steam outlet pipe outside is with dried master mode filter core, leaves air vent between steam outlet pipe and the dried master mode filter core; The gapped equal sheet of air that is with in dried master mode filter core middle and upper part, outside, the equal sheet of air outside is last shell, and the top of last shell has inlet hole, and inlet hole is connected with suction tude; Oil removal retaining soil dish is for having only the back-off frustoconic shape of upper surface and side, is end opening below it, have on its upper surface suitable for reading, dried master mode filter core lower end be fastened in its suitable for reading on, its end opening is fastened on the outer wall boss of thread filter core; Having a dedusting mouth on the shell on the close oil removal retaining soil dish end opening, fix a unidirectional laying dust cap on the dedusting mouth; One internal orifice that is slightly larger than steam outlet pipe is arranged in the middle of the thread filter core, its by inwall, with the outer wall of a boss, be fixed on that the oil immersion silk of loam cake between outer wall and the inwall and subiculum, irregular arrangement forms, the oil immersion silk of irregular arrangement is positioned at the space that outer wall, inwall, loam cake and subiculum are surrounded, and has a plurality of openings on loam cake and the subiculum; The upper end of steam outlet pipe is fixed on the shell, and the lower end is at the internal orifice place of thread filter core; The outside of thread filter core is a lower casing, and lower casing and last body seal are fixed together, and are placed with pure machine oil in the lower casing, below thread filter core, in the lower casing air inlet oil blocking barrel that has suction port on the wall is arranged.

The utility model combines dried master mode filter core and oil immersed type filter core, its compact structure, the air that uses for motor has carried out coarse filtration, the essence filter of dried master mode filter core, the leakage soil of oil removal retaining soil dish, the smart again filter of thread filter core, the cleaning of five road processes of last oil filter, and whole filter gas process air stroke is briefly fluent, filtering effect is very good, guaranteed the absolute cleaning of air, improved the power of locomotive engine, prolonged locomotive engine working life, thereby prolonged the working life of locomotive, on the motor of the locomotive that is operated in windy and dusty area, more demonstrated its advantage.The utility model is simple in structure, it is single to have changed original filter cleaner filtering effect, the weakness of weak effect, after its air through coarse filtration enters the utility model, earlier, even air is entered in the dried master mode filter core, when having overcome former dried master mode filter cleaner air and directly entering filter core through being evenly distributed of the equal sheet of air, because the air pressure part is bigger than normal, and the filter core that causes junk and the deadly defect that enters body.Long service life of the present utility model, and, guaranteed being perfectly safe of motor because the special construction of thread filter core and the effect of air inlet oil blocking barrel can not be inhaled in the steam outlet pipe pure machine oil and the interior pure machine oil of lower casing in the thread filter core.
