Abstract
The utility model relates to a diesel engine respirator assembly of Cummins series, comprising a casing, a filter core, an air entraining pipe, and other main parts, wherein, the air entraining pipe is connected with an exhaust port of the casing. The utility model is characterized in that: the filter core is positioned in a filter cavity inside the casing, the wall of the filter cavity is provided with a baffle to form an airflow labyrinth; the air entraining pipe is a metal bellow. The respirator assembly has a reasonable structure and a good oil mist filtration effect, as the entraining pipe with metal bellow form is adopted, the installation is convenient; meantime, the circulation sectional area is not affected during high temperature, folding or vibration; problems of exhaustion blocking, over high pressure inside cavities of relative parts of the engine, seal component damage, etc. are prevented, and reliability of Cummins diesel engine is improved.
Description
Technical field: the utility model belongs to the diesel engine field, relates to functional part one resuscitation apparatus of diesel engine, mainly is a kind of resuscitation apparatus of east wind comings series diesel engine.
Background technique: during diesel engine work, the pressurized gas that diesel combustion forms promote piston motion in cylinder, thereby driving crankshaft rotating, in pair clearance in the cylinder cause pressurized gas to bleed the cavity volume that crankcase, gear chamber, oil sump etc. communicate, cause this cavity volume internal air pressure to raise, cause faults such as damaging sealing, the chamber internal air pressure must be discharged, adopt resuscitation apparatus to realize usually.East wind comings series diesel engine is to introduce a kind of diesel engine that American technology is produced the eighties.Its existing air pressure discharges solution and is achieved in that cavity of punching press on the crankcase side cover plate, outwards protrude, the welding plate washer forms the air-flow labyrinth in the cavity, cavity outside weldings pipe is chewed logical labyrinth, and pipe is chewed to connect with a rubber hose by clip gas is drawn.In actual application, because the labyrinth structure scheme is unreasonable, in the time of can not solving owing to the diesel engine high speed operation well, the filtration problem of the machine oil mist that in crankcase, forms, when having air entraining pipe exhaust release of pressure, machine oil is the vaporific body of being taken out of, accelerates consumption of lubricating oil on the one hand, causes environmental pollution on the other hand; More serious problem is, the Cummins Engine machine is parts, pipeline complexity near outlet pipe is chewed, the very easily distortion in assembly process of the outlet pipe of rubber material, nest folding, and through the paint drying tunnel time, this pipe, is subjected to be softened after the higher temperature baking from nearer apart from the hyperthermia radiation spacing, transport later at motor, with situations such as main frame assembling, operational shock under often aggravated distortion, nest is discounted and is resembled, cause air-flow not smooth, cause the crankcase internal air pressure to raise, wash out phenomenons such as related seals pad.
Summary of the invention: the utility model is for solving comings diesel engine the problems referred to above, a kind of comings series diesel engine air breather assembly is proposed, comprise housing, filter core, several critical pieces such as air entraining pipe, described air entraining pipe is connected with the relief opening of described housing, it is characterized in that: described filter core is positioned at the filtering cavity of described housing, described filtering cavity chamber wall is provided with plate washer, forms the air-flow labyrinth; Described air entraining pipe is a metal bellows.This air breather assembly is rational in infrastructure, the mist of oil good filtration effect, owing to adopt the air entraining pipe of wavy metal form of tubes, both convenient the installation, do not influence actual internal area simultaneously when high temperature, nest folding or vibration, avoided exhaust not smooth, motor associated components chamber internal air pressure is too high, damage problems such as Sealing, improved the reliability of comings diesel engine.
Description of drawings: Fig. 1, the utility model air breather assembly structural representation;
Fig. 2, the structural representation of the housing of the utility model air breather assembly.
Embodiment: as shown in Figure 1, 2, this air breather assembly comprises housing 1, filter core 2, and several critical pieces such as oiling body 4, air entraining pipe 7, housing 1 and oiling body 4 adopt the Reinforced Nylon material, and air entraining pipe 7 is a metal bellows.Housing 1 is provided with that suction port 10, screw thread 9, high-order exhaust chew 8, plate washer 3, oiling body 4 be provided with oil filler 5, oiling chamber A and with plate washer 3 similar plate washers.Housing 1 adopts welding or technique for sticking to connect with oiling body 4, constitutes filtering cavity B, and B is provided with filter screen in the chamber, logical relief opening 6, and the some plate washers on housing 1 and the oiling body 4 form the air-flow labyrinth, and communicate with each other by suction port 10 in A chamber and B chamber.The mounting type of this resuscitation apparatus for by with housing be that holistic screw thread 9 is tightened on the gear chamber cover outside, by suction port 10 with gear-box, crankcase and resuscitation apparatus A chamber and the communication of B chamber.During engine operation, the gas that the high pressure of crankcase contains the machine oil mist enters filtering cavity B by the gear-box inner chamber through suction port 10, forms turbulent flow in its labyrinth structure, constantly the machine oil mist is fully filtered, machine oil attached on the filter core, after separating out, machine oil is flowed back in the gear-box; Pressurized gas enter air entraining pipe 7 along flowing to shown in the arrow through relief opening, and the air-flow that filtration is separated out behind the machine oil excludes.For motor filling machine oil the time, the lid 11 of the oil filler 5 of outwarding winding, machine oil, is entered in the engine block through suction port 10 by oiling chamber A by oil filler 5.This air breather assembly is installed on the gear-box side plate, it is rational in infrastructure, the mist of oil good filtration effect, owing to adopt the air entraining pipe of wavy metal form of tubes, both convenient the installation do not influence actual internal area simultaneously when high temperature, nest folding or vibration, avoided exhaust not smooth, motor associated components chamber internal air pressure is too high, damages problems such as Sealing, has improved the reliability of comings diesel engine; Also have machine oil simultaneously and add pouring functions.
