According to the utility model, the chambers of traditional structures are changed to be vertically arranged, the design of pinhole muffling is adopted, and the muffler has a favorable muffling effect within a wider frequency band range, not only the complete machine electricity generation power demand can be met, but also the aim of noise reduction is played, and the universal power machine muffler can meet the entire automobile arrangement demand with multiple types of displacements.
Description
Technical field
The utility model relates to silencing apparatus, particularly a kind of general dynamic machine silencing apparatus.
Background technique
General dynamic machine (such as the supporting power engine of generator) is eliminated the noise to be held in esteem gradually and is looked.Exhaust silencer performance quality has very big influence to influence and the power character to surrounding environment.Impedance convolution exhaust silencer is used more and more widely on petrol engine, diesel engine at present.The fitness for purpose vent systems is satisfying under exhaust back pressure and the not loss effective engine power situation, reduces the noise of broad frequency band as far as possible.The petrol engine vent systems generally is arranged as secondary or multistage, but secondary or multistage silencing apparatus often are difficult to satisfy the car load layout requirement because of silencing apparatus volume or length increase, and the use of single-stage silencing apparatus can't reduce the purpose of petrol engine exhaust sound.We can say to have now and also do not reach well-content effect about the design of exhaust silencer and the research of acoustic characteristics.
The model utility content
The utility model purpose provides a kind of silencing apparatus, in the broad frequency band scope, has good noise elimination effect, can satisfy complete machine generated output demand, plays the purpose that reduces noise again, can satisfy the vehicle complete vehicle arrangement requirement of multiple discharge capacity.
The described silencing apparatus of the utility model; Comprise the housing that is provided with suction port and relief opening; And be arranged at the dividing plate in the housing, and said dividing plate comprises first dividing plate and second partition, first dividing plate and second partition laterally arrange and housing are separated into three chambers vertically arranged side by side;
Suction port is arranged on the top chamber housing sidewall, and relief opening is arranged on the housing sidewall of bottom chamber, is communicated with relief opening in the housing outlet pipe is set, and outlet pipe is offered the perforation that is communicated with self tube chamber away from end face seal, the sidewall of relief opening one end;
Also comprise and run through first dividing plate and be communicated with top chamber and the short intervalve of middle part chamber, and run through first dividing plate and second partition and be communicated with top chamber and the long intervalve of bottom chamber; Second partition is provided with bloop, and said bloop is relative with end intervalve air outlet.
Preferably, the indoor sidewall of center lumen is covered with the cotton layer of noise reduction.
Preferably, lack intervalve and be straight tube and the vertical dividing plate that runs through with long intervalve.
Preferably, the cross section of said three chambers is circle.
Preferably, the outer connection with suction port of housing is provided with suction tude, and the airintake direction of suction tude is along top chamber radially.
The beneficial effect of the utility model: the silencing apparatus of the utility model structure is changed into the vertical direction setting with the chamber of conventional construction; Adopt the design of aperture noise reduction, made it in the broad frequency band scope, have good noise elimination effect, can satisfy complete machine generated output demand; Play the purpose that reduces noise again; Can satisfy the vehicle complete vehicle arrangement requirement of multiple discharge capacity, and simple in structure, be easy to realize.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is Fig. 1 right elevation;
Fig. 3 Fig. 1 plan view.
Embodiment
