Description
Technical field
The utility model relates to a kind of muffler for motor, refers to a kind of diesel engine silencing apparatus especially.
Background technique
Diesel engine is that burning diesel oil is to obtain exergonic motor, belong to compression-ignited, be characterized in: 1. good dynamic property, the thermal efficiency is high, 2. the weight of specific power is low, and 3. extensively adopting exhaust gas turbocharge and improve supercharging level, is 4. that diesel engine does not have ignition system, so the less maintenance of fault is easy, reliable operation.But because the working principle of diesel engine, the unexpected perfect combustion of diesel oil can make the gas undergoes rapid expansion in cylinder, such piston has a swift and violent active force down, at this moment because the running inertia of motor, piston can not down move smoothly very much, will cause engine knock like this, and namely piston skirt and cylinder wall collide, can operationally produce larger noise, noise pollution is caused to environment.
Model utility content
Therefore the utility model proposes a kind of diesel engine silencing apparatus, solve the problem that conventional diesel operating noise is excessive.
The technical solution of the utility model is achieved in that a kind of diesel engine silencing apparatus, comprises front cover, front dividing plate, outlet pipe, rear end cover, rear bulkhead, suction tude, housing, before and after housing, side has opening, described front cover is located at housing front openings place, described rear end cover is located at housing rear openings place, front cover, rear end cover and housing form airtight chamber jointly, described front dividing plate, rear bulkhead is located at enclosure interior from front to back successively, and front cover, rear end cover, front dividing plate and rear bulkhead are parallel to each other, airtight chamber is divided into the first chamber distributed from front to back by front dividing plate and rear bulkhead, second chamber and the 3rd chamber, the outlet of suction tude is successively through front cover, front dividing plate and rear bulkhead, be installed on the 3rd chamber, the entrance of outlet pipe is successively through rear end cover, rear bulkhead and front dividing plate, be installed on the first chamber.
The 3rd chamber that described rear bulkhead and rear end cover are formed is expansion cavity, air-flow flows into from the suction tude of silencing apparatus, expansion cavity is flowed into by the end of suction tude, air-flow at this moment flow velocity is slack-off, then successively by rear bulkhead, the second chamber, front dividing plate, the first chamber, the noise of air-flow in flow process is also corresponding to diminish and then reaches the object reducing noise, discharges eventually through outlet pipe.
Further, described suction tude is connected by welding manner with front dividing plate, and described outlet pipe is connected by welding manner with rear bulkhead.Connect more fastening.And such structure is compact in limited space, chassis arranges silencing apparatus, maximizedly make use of space.
Again further, the volume of the first chamber is equal with the volume of the 3rd chamber, and the volume of the first chamber is greater than the volume of the second chamber.
Again further, the suction tude between described front cover and front dividing plate is surrounded by suction tude involucrum, the outlet pipe between described rear bulkhead and rear end cover is surrounded by outlet pipe involucrum, play the effect improving erasure effect.
By above-mentioned disclosure, the beneficial effects of the utility model are: three chambers formed by forward and backward dividing plate and housing, reduce the pressure and the flow velocity that enter expansion intracavity gas from suction tude, and then reach the object reducing noise.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, diesel engine silencing apparatus, comprises front cover 1, front dividing plate 2, outlet pipe 3, rear end cover 5, rear bulkhead 6, suction tude 7, housing 8.
Before and after housing 8, side has opening, the conveniently dismounting of front cover 1 and rear end cover 5, described front cover 1 buckles into housing 8 front openings place, described rear end cover 5 buckles into housing 8 rear openings place, front cover 1, rear end cover 5 and housing 8 form airtight chamber jointly, described front dividing plate 2, it is inner that rear bulkhead 6 is located at housing 8 from front to back successively, and front cover 1, rear end cover 5, front dividing plate 2 and rear bulkhead 6 are parallel to each other, airtight chamber is divided into the first chamber distributed from front to back by front dividing plate 2 and rear bulkhead 6, second chamber and the 3rd chamber, the volume of the first chamber is equal with the volume of the 3rd chamber, the volume of the first chamber is greater than the volume of the second chamber, the outlet of suction tude 7, successively through front cover 1, front dividing plate 2 and rear bulkhead 6, is installed on the 3rd chamber, and the entrance of outlet pipe 3, successively through rear end cover 5, rear bulkhead 6 and front dividing plate 2, is installed on the first chamber.
