Description
Technical field
The utility model relates to a kind of suction silencing apparatus that is used for the sealed mode refrigeration compressor.
Background technique
Noise has been regarded as one of severe contamination.As the power source and the heart of domestic refrigerating appts, the noise problem of refrigeration compressor is to become an important indicator weighing its combination property.In fact for a compressor, most of noise all is because housing is excited (for example by spring, refrigerant pressure pulsation, outlet pipe, the lubricants capacity equal excitation) that is produced by some noise source.But the noise source of compressor and transmission way complexity are various, and this has brought very big difficulty with regard to the noise elimination noise reduction of giving compressor.The main noise source of refrigeration compressor is made up of the aerodynamic noise of air inlet and exhaust emission, mechanical noise and drive motor noise three parts that mechanical moving element produces.The induction noise of compressor is owing to the pressure pulsation of air-flow in suction tude produces.The fundamental frequency of induction noise is identical with air pulsing frequency in the suction tude, and is relevant with the rotating speed of compressor.The exhaust sound of compressor is because air-flow produces due to the pressure pulsation in outlet pipe.Exhaust sound than induction noise a little less than, so the air power noise of compressor is generally based on induction noise.By being set, the inlet and outlet silencing apparatus reduces noise, silencing apparatus in the hermetic compressor is generally reactive muffler, it utilizes that pipeline section changes, resonant cavity causes that acoustic impedance changes and reflects or sound energy consumption, or utilizes sound path official post sound wave phase phase difference 180 degree to offset noise in the silencing apparatus.
Because the volume in the compressor housing is less, in the prior art, generally select the reactive muffler of single form for use, it is divided into two types: the one, and the expansion chamber silencing apparatus, it adds that by the inlet and outlet mouth inner chamber forms, and cavity volume is bigger than inlet and outlet mouth, the 2nd, and RESONANT CAVITY MUFFLER, it is made up of air inlet and exhaust piper, and around air inlet and exhaust piper an inner chamber being arranged is resonant cavity.The silencing apparatus of single form is that selection is a kind of in above-mentioned two types, and advantage is simple in structure, and the reliability height is easy to manufacture, and shortcoming is that the noise elimination effect is undesirable.
The model utility content
The purpose of this utility model is to have proposed a kind of suction silencing apparatus that is used for the sealed mode refrigeration compressor, it solves single form silencing apparatus noise elimination poor effect problem in the prior art, can weaken to greatest extent air-flow in suction tude pressure pulsation and the noise that produces, and easy to manufacture, reliability is higher.
The utility model adopts following technological scheme:
A kind of suction silencing apparatus that is used for the sealed mode refrigeration compressor, it is a silencing apparatus cavity, described silencing apparatus cavity is provided with air outlet and suction port, it is characterized in that: described silencing apparatus cavity is made up of spill upper shell and the butt joint of spill lower shell body, upper shell is provided with the air outlet and is connected with steam outlet pipe, lower shell body is provided with suction port, joint have a dividing plate with its internal separation for becoming upper gas chamber and lower chamber; Dividing plate is provided with the breather line that is communicated with upper gas chamber and lower chamber.
As optimization, the suction port of the lower end mouth of described breather line on the lower shell body, the upper end-hole of breather line is over against the air outlet of upper shell.
As optimization, the butt joint end face of upper shell and lower shell body adopts concavo-convex slot card button to be connected, and the inboard, butt end of lower shell body also is provided with convex shoulder, and dividing plate places on this convex shoulder, and upper shell and lower shell body are pegged graft and simultaneously dividing plate be pressed on the convex shoulder.
Can understand like this, upper gas chamber of the present utility model is an expansion chamber, and lower chamber resonant cavity, whole silencing apparatus are equivalent to be in series by a RESONANT CAVITY MUFFLER and an expansion chamber silencing apparatus, eliminate the noise of different frequency respectively.
The utility model is the complex muffler that a kind of employing has expansion chamber and resonant cavity, can eliminate the noise of different frequency respectively, thereby improves erasure effect widely; And simple in structure, make assembling easily, the reliability height.
